Enormous wildfires spark scramble to improve fire models
(Nature) Jeff Tollefson, Aug. 31
…“Something is definitely different, and it raises questions about how much we really know,” says Max Moritz, a fire scientist at the University of California, Santa Barbara.
… The problem, Moritz says, is that most of the fire models in use today are based on data from the past two or three decades. But it seems that fire behaviour might be shifting in response to climate faster than anybody expected, and that makes it increasingly problematic to extrapolate from past trends, he adds.
Rodent control critical in subsurface alfalfa systems

For alfalfa growers seeking other methods of rodent control, Dr. Roger Baldwin, Cooperative Extension specialist at UC Davis, says rodenticides, fumigants and trapping can be moderately to highly effective, depending on method and means used.
Deeply Talks: Fire & Drought–The Extremes Become Routine
(Water Deeply) Matt Weiser, Aug. 30,
The American West has entered an era of permanent water scarcity, a marked shift from previous periods of episodic drought. The same can now be said for fire: In California, there hasn't been a month without a wildfire since 2012. Join us for a conversation about the ways in which water and wildfire management intersect, and about the West's adaptation to its new, and far from normal, reality. We'll be joined by experts Crystal Kolden, associate professor of forest, range, and fire sciences in the College of Natural Resources at the University of Idaho, and Van Butsic, cooperative extension specialist at the University of California, Berkeley. Email our community editor with questions for the panelists (firstname.lastname@example.org) or tweet us @waterdeeply using the hashtag #DeeplyTalks.
Deadly poultry ailment, Newcastle disease, reaches Ventura County
(Ventura County Star), Aug. 29
Maurice Pitesky, a veterinarian and University of California extension specialist in the School of Veterinary Medicine at UC Davis, said one of the challenges in keeping a lid on the disease is the continued popularity of raising backyard chickens.
“While people have the best intentions, unfortunately a lack of biosecurity practices in people's backyards is one of the contributing factors of the disease spreading,” Pitesky said.
The longtime head of the UFW is stepping down. His replacement will be the first woman to lead the union
(LA Times) Geoffrey Mohan, Aug. 28
At its heart, the UFW remains torn between whether it can be both a grass-roots union and a broad social movement operating in the halls of power, said Philip Martin, a UC Davis agricultural economist and farm labor expert.
...“It is worth noting that the UFW does not have union locals, and so therefore does not have a system under which current farmworkers are trained in leadership development with the idea that they will rise within the union,” he said.
Expert Views: Managing Wildfires to Protect Water Resources
(Water Deeply) Lindsay Abrams, Aug. 28
Van Butsic, cooperative extension specialist at the University of California, Berkeley:
"Managing forest and wildfires to benefit water resources is difficult because there are trade-offs between short-term costs and long-term benefits. In the short term, wildfires can lead to increased erosion and sedimentation in streams and reservoirs. This contributes to lost revenue for downstream power generators and at times even requires water to be treated before it is potable."
Can Angelenos and Coyotes Coexist?
(LA Magazine) Henry Cherry, Aug. 27
…Intrigued by the animals, I stumbled across Coyote Cacher, an interactive website operated by University of California's Dr. Niamh Quinn. A native of Ireland, Quinn has been studying coyotes for about four years. “There are no coyotes in Ireland, but when I came here there was the need for coyote research in Southern California,” Quinn says. “There is a need for professional extension to the cities and the police departments, the people that never managed coyotes before but all of a sudden find themselves needing to do so.”
Why homes are lost to wildfire — is yours as safe as it could be?
(Mercury News) Lisa Krieger, Aug. 27
…“When you start to understand why homes burn, often through embers igniting fuel in home attics or adjacent to homes, then it is easier to understand these patterns,” said Kate Wilkin, a fire specialist for UC Cooperative Extension.
Limiting suburban sprawl can ease the devastation of wildfires
(Mother Nature Network) Matt Hickman, Aug. 27
…But there's a bigger issue at hand. Max Moritz, a wildfire specialist with the University of California's Division of Agriculture & Natural Resources, relays to Martin Kuz of the Christian Science Monitor that inaction from state lawmakers who are reluctant to lead the charge in restricting development in vulnerable areas is only worsening the situation. Presently, local officials, developers and homeowners face few limitations when building in fire-prone wild land urban interfaces. Moritz refers to this as a “political will problem.”

Idea to Reduce Glyphosate Use with Grapes
(Cal Ag Today) Mikenzi Meyers, Aug. 23
John Roncoroni, a UC Cooperative Extension Weed Science Farm Advisor in Napa County, has made strides toward meeting this challenge. “Many times, growers will do two applications of herbicides during the year … but what I'm trying to do is push it back to post-leaf fall after the season to clean up and come back with a pre-emergent material right before bud break then maybe skip that last glyphosate treatment after bud break.”

The Social Costs of Living in Wildfire-Prone Areas
(East Bay Express) Alastair Bland, Aug. 21
…"But that's so politically contentious — it's a line politicians walk up to but turn away from," said William Stewart, a UC Berkeley forestry and wildfire specialist.
… “People seem to have short memories," said Sabrina Drill, a natural resources advisor for the UC Cooperative Extension, a statewide off-campus division of the university system that focuses on agriculture and natural resources. "I think people might think twice about building a home where there had just been a fire, but people seem to forget after about three years."
… Van Butsic, a UC Berkeley researcher who studies forestry and land use, has closely studied this. In a paper now under review for publication, he and scientist Anu Kramer, from the University of Wisconsin, describe an alarming trend of building homes in known fire-risk areas.
"We studied 30 of the largest fires since 1970," he said. On average, they found that 20 years after an inhabited area burns, not only were most of the destroyed homes rebuilt but many new homes were added — about twice as many homes in total as there were at the time of the burn.
… In 2016, researcher Susan Kocher spent nine months on sabbatical in Provence, the arid region of southern France that resembles much of inland California. Here, Kocher — the Central Sierra Natural Resources Advisor for the UC Cooperative Extension — compared building patterns in high-fire risk parts of California and France.
"In California we often say, 'We should be able to tell people they can't build here,'" said Kocher, whose research, coauthored with Butsic, was published in March of 2017 in the journal Land. "In France, they just tell people they can't build somewhere."
Cooperative Extension adapts to a less agricultural America

Israel and UC deepen water technology collaboration
(Jewish News of Northern California) Hannah Jannol, Aug 17
S.F.-based Consul General of Israel Shlomi Kofman attended the MOU signing ceremony on July 16, held during a three-day workshop titled, “The Future of Water for Irrigation in California and Israel.” The document was signed by an agricultural division of the University of California, UC Davis and the Agricultural Research Organization of Israel.
… Doug Parker, director of the California Institute for Water Resources, helped put the MOU together. He said California and Israel already work together frequently on water research, but formalizing the relationship could give the two parties more leverage when applying for grants and funding.
‘Batnadoes' Can Protect California's Crops
(Atlas Obscura) Anne Ewbank, Aug. 16
… He's likely right, according to Rachael Long, a farm advisor with the UC Cooperative Extension in the Sacramento Valley. She's researched for decades how bats can help farmers control pests. “Armyworms are always a big problem in rice production,” she says. “Bats are predators, of armyworms, cutworms, and other pests.” Bats' nocturnal feasts prevent adult moths from laying eggs that will hatch into hungry, rice-eating caterpillars, and, Long says, their impact cannot be overstated. When pest populations get out of control, “it can be really devastating.”
Wildfires Are Inevitable – Increasing Home Losses, Fatalities and Costs Are Not
Wildfire has been an integral part of California ecosystems for centuries. Now, however, nearly a third of homes in the state are in wildland urban interface areas where houses intermingling with wildlands and fire is a natural phenomenon. Just as Californians must live with earthquake risk, they must live with wildfires.
UC: Tariffs could cost fruit, nut industries over $3 billion
(Farm Press) Aug. 15
A new report released by the University of California Agriculture and Natural Resources' Agricultural Issues Center estimates the higher tariffs could cost major U.S. fruit and nut industries $2.64 billion per year in exports to countries imposing the higher tariffs, and as much as $3.34 billion by reducing prices in alternative markets.
Evacuation priorities: Save people first, then livestock

In California's new wildfire reality, facing the need for periodic fires to clear fuel
(SF Chronicle) Kurtis Alexander, Aug. 13
While misguided forest- management policies are just one reason that fire has become more devastating, a warming climate and more development in California's wildlands also contribute, making planned burning vital, said wildfire specialist Max Moritz with UC's Division of Agriculture and Natural Resources.
“We need to become more comfortable with fire as a tool,” he said. “Prescribed fire could do a lot of good, restoring these forests to healthy conditions and reducing the fire hazard.”

UCCE Manure Nitrogen Study Update in Dairy Feed Crops
(California Dairy Magazine) Aug. 10
It takes time for the nitrogen found in dairy manure water to become available to feed crops out in the field, and as dairy producers don't want to under or over fertilize their feed crops, the UC Cooperative Extension is conducting a research trial to find out more regarding how manure water interacts in the soil with plant root systems. Watch this brief interview UC Agronomy Advisor Nicholas Clark as he summarizes a recent presentation he shared at the Golden State Dairy Management Conference.

Drought may be increasing camel cricket numbers
(Farm Press) Tim Hearden, Aug. 8
A few years ago, University of California viticulture and pest management advisors noticed unusual leaf symptoms in certain Napa County hillside vineyards that were right next to oak woodlands.
As described by the UC Cooperative Extension's Monica Cooper and Lucia Varela, the feeding activity they noted in April 2015 resulted in a “lace-like” appearance to damaged leaves. Then last year, in March, they observed feeding damage to expanding buds.
… Where vineyards have come into play is when they were situated on hillsides next to oak woodlands and mixed species of white alders, madrone, California bay, and Douglas fir, according to Varela, a north coast integrated pest management advisor, and Rhonda Smith, a UCCE viticulture advisor.
Yes, humans have made wildfires like the Carr fire worse. Here's how.
(Washington Post) Sarah Kaplan, Aug. 8
…Many forests in the western United States are “fire adapted” said Scott Stephens, a fire ecologist at the University of California at Berkeley. Natural wildfires every 5, 10 or 20 years help clear debris from the forest floor and make room for stronger, healthier trees.
…Wildfires are as unstoppable as hurricanes, Stephens said — and much like hurricanes, increasingly inevitable as the climate changes. “But you could do a lot more when you're getting ready for fire to inevitably occur,” he said. By building with fire-safe materials, establishing buffer zones between ecosystems and communities, and better caring for forests before fire season starts, some of the destructiveness of fires could be mitigated, Stephens said.
The staggering scale of California's wildfires
(New York Times) Lisa Friedman, Jose A. Del Real, Aug. 8
…Lisa: Mr. Trump in his tweet referred to the longstanding dispute between California farmers and environmentalists over the allocation of the state's precious water resources. Both sides want more and Mr. Trump has embraced the arguments of the agriculture community.
But William Stewart, a forestry specialist at the University of California, Berkeley said leaving less water for fish would have no impact on amount available for fighting fires. That water comes from local streams and rivers, where water-dropping helicopters drop their buckets. Neither he nor other scientists could point to a scenario in which California's environmental laws have prevented or curbed the use of water to fight wildfires.
California giving out $170 million in cap-and-trade revenue to help prevent wildfires
(San Francisco Chronicle) Kimberly Veklerov, Aug. 8
…Groups in six Bay Area counties will get a combined $7.4 million. The biggest portion of that, $3.6 million, will go to UC Berkeley. The Federal Emergency Management Agency in 2016 withdrew what would have been an award of roughly the same amount to thin and remove eucalyptus trees in the East Bay hills after a lawsuit by conservation activists.
…Keith Gilless, chairman of Cal Fire, said the state needs to do much more vegetation management — activities like reducing hazardous plant fuels — to address wildfire risk.
“One of the things we need in California moving forward is striking a better balance between carbon sequestration in forests and the risk associated with that densely stocked carbon sequestration,” said Gilless, also a UC Berkeley professor of forest economics. “We need to figure out ways to do vegetation management that are socially acceptable with the smallest public subsidy possible.”
These California counties have the highest concentration of homes vulnerable to wildfire
(Sac Bee) Michael Finch II, Aug. 7
In the case of the northern counties, the risk will be higher because homes there often dispersed at the edge of a wildland area, said Lenya Quinn-Davidson, a Eureka-based fire advisor for the University of California Division of Agriculture and Natural Resources.
“Those areas that you mentioned are areas that have a lot of homes mixed into the wildland-urban interface — areas where there are a lot of homes that are edgy and in the forest and have a lot of fuel.”
Can More Logging Help Prevent California Wildfires?
(KQED) Forum, Aug. 7
Cal Fire officials announced yesterday that the Mendocino Complex fire grew to over 283,000 acres, making it the largest in state history. As wildfires across the state rage on, Governor Brown and some lawmakers are calling for increased forest thinning to lessen the threat posed by fires. Those in favor of logging say that removing trees and vegetation can help reduce a fire's intensity and make forests more resilient. Opponents say thinning does nothing to protect communities from fires and imperils species that depend on dense forests. We'll take up the debate.

Trump wants to clear more trees to halt fires. The feds need to spend more, experts say.
(Sac Bee) Emily Cadei and Kate Irby, Aug. 7
“I think for a number of years the feds were more ahead of this dilemma, at least in discussions,” said Scott Stephens, a professor of fire science at the University of California, Berkeley. But “I have to say right now, I think the state is moving ahead. It's certainly being more innovative, it's doing more policy work.”
Trump says California's water policies are making the wildfires worse. Is he right?
(Sac Bee) Dale Kasler, Aug. 6
William Stewart, a forestry management expert at UC Cooperative Extension, agreed. “The entity that's doing the worst job are the people working for him,” Stewart said, referring to Trump.
Stewart said the Carr Fire, which killed seven people and forced mass evacuations in and around Redding, started in shrub and grasslands west of the city, not in the forests. Only lately, after the threat to Redding abated, has the fire moved north onto Forest Service land and forested property owned by Sierra Pacific Industries, he said.

Cal Fire responds to President Trump's tweet about state wildfires
(ABC7) Rob McMillan, Aug. 6
Cal Fire and a researcher from UC Riverside responded to Donald Trump's tweet related to the state's wildfires on Monday.
"Thinning would be a good idea, but the question is how you thin properly," UC Riverside's Dr. Richard Minnich said.
"There are too many trees in the ground sucking the ground dry. That's one of the reasons you had so many trees die in the Sierras."
But Minnich says that there is plenty of water in California. Shasta is the biggest reservoir in the state and it's currently more than two-thirds full.
California Wildfires: It's a people problem
(East Bay Times) Lisa Krieger, Aug. 5
Even as fires rage across California, thousands of new homes are being built deeper into our flammable foothills and forests, as lethal as they are lovely.
A big reason why: It's harder to do controlled burns — one of the most effective fire suppression techniques — near residential areas, due to smoke concerns. Until the 1970's, fire suppression tended to minimize fire spread.
“If homes are sprinkled through the landscape, you take that key tool off the table,” said Max Moritz, a wildfire specialist with UC's Division of Agriculture & Natural Resources.
Report: Future climate could affect street trees

Wildfires force California to reckon with a not-so-new normal
(Christian Science Monitor) Martin Kuz, Aug. 3
…The committee's focus on improving utility grid safety and examining the liability of power companies reflects the causes of several blazes in 2017. The absence of land use planning from its agenda suggests what Max Moritz, a wildfire specialist at the University of California, Santa Barbara, describes as a “political will problem.”
“If you want to keep communities safe, then you have to think about living differently, about where and how we build our communities,” he says. “But there's no bill in the legislature about that.”
Will smoke taint summer harvests in the Mother Lode?
(The Union Democrat) Giuseppe Ricapito, Aug. 3
Drift smoke from the Ferguson Fire has some Tuolumne County vintners and agriculturalists concerned about the commercial viability of the early fall grape harvest, but one forestry official with the University of California noted that the native wilderness of the Mother Lode has a developed adaptability to smoky conditions.
Susie Kocher, forestry and natural resources advisor with the University of California Department of Agriculture and Natural Resources Central Sierra Cooperative Extension, said that “smoke taint” of commercial agriculture was always a concern during fire season.
“It's grapes we worry about the most,” she said. “In the past there have been bad years when there was a lot of smoke where grapes were on the vine and wineries had to produce the smoky wine because of that effect.”
Coyote encounters expected to rise during heat and drought
(ABC 10) Jared Aarons, Allison Horn, Aug. 2
The record-breaking heat and drought are forcing animals, including coyotes, out of their natural habitats and closer to humans…
The University of California Coyote Catcher website tracks sightings and attacks. Their figures for 2018 show coyote incidents are down compared to last year. In 2017, there were 142 coyote attacks. More than halfway through 2018, San Diego is on track to stay below that number, with 64 attacks.
According to the website, there have been six reported pet deaths this year.

Growers prepare for smaller prune harvest
(Farm Press) Tim Hearden, Aug 2
…With guidance from University of California Cooperative Extension advisors, growers have been paying close attention to tree water stress and sugar levels in the weeks leading up to the harvest, which was expected to begin in about the third week of August.
… “It's probably going to vary a little bit because the cropping is really variable,” UCCE advisor emeritus Rick Buchner says of the prune crop. “Some of it is good and some is really light. We had a heck of a time pollinating them.”
…“Harvest can be a nerve-wracking time in the prune business,” UCCE advisors Franz Niederholzer and Wilbur Reil note in a California Dried Plum Board blog post. “The finish line – when the entire crop is in the bins – may be in sight, but here are still tough decisions to be made that influence your bottom line.”
…In general, harvest can be expected roughly 30 days after the first healthy fruit in an orchard starts changing color, UCCE orchard advisor Katherine Jarvis-Shean explains in a separate blog post. She urged growers to time their irrigation cut-off to improve dry-away ratios, reduce premature fruit drop and decrease shaker bark damage at harvest.

Agricultural advances draw opposition that blunts innovation
(Science) Anne Q. Hoy, June 29
Scientists are using technology to expand global food production and ease its environmental impact, but advances are being challenged by claims that lack scientific evidence and raise public distrust and concern, a leading agricultural scientist told an American Association for the Advancement of Science audience.
Alison Van Eenennaam traced the advent of campaigns against agricultural innovations related to areas from cattle and chicken production systems to plant biotechnology. The impact such efforts are having on agricultural advances was the focus of the ninth annual AAAS Charles Valentine Riley Memorial Lecture on 5 June at the AAAS headquarters in Washington, D.C.
UC Davis Experts Help Farmers, Ranchers Profit in Growing Trend
(Cal Ag Today) Patrick Cavanaugh, June 29
Many farmers could benefit from agritourism and the added value it brings, but developing successful agritourism operations can be tricky. Experts at the Agricultural Sustainability Institute (ASI) at UC Davis are helping farmers and others in the agricultural community understand the regulations, permits, insurance, marketing and other considerations needed to succeed.
“Agritourism operations are more successful when they're part of a supportive community of tourism professionals, county regulators, agriculture regulations and others,” says Gail Feenstra, ASI's food, and society coordinator.
Feenstra and her team recently received a $73,000 grant from Western Sustainable Agriculture Research and Education, a U.S. Department of Agriculture program, to develop training, resources and peer support for farmers and ranchers considering agritourism. Feenstra is working with Penny Leff, ASI's statewide agritourism coordinator and team project manager.

Mechanized vineyard saves labor, boosts quality
(Western Farm Press) Tim Hearden, June 27
Kaan Kurtural started working on a fully mechanized vineyard to help growers save on labor costs, but then he noticed it also produced grapes with superior quality.
“We made wine from these last year and compared it to our traditionally-farmed vineyards,” says Kurtural, a specialist in the University of California-Davis Department of Viticulture and Enology. “Until we tell people what it is, they can't distinguish the quality of the fruit or the wine.”

(Western Farm Press) Tim Hearden, June 27
As most fumigants in California are being phased out, growers are having to find other ways to control weeds in young vineyards.
And while weeding by hand has been done, increased costs and a shrinking labor force have made this task impractical, says John Roncoroni, University of California Cooperative Extension Weed Science Farm Advisor in Napa County.
New podcast offers advice to California farmers
(Capital Press) Padma Naggapan, June 26
Two enterprising farm advisors with the University of California's cooperative extension have begun a podcast that will focus on tree crops and other produce grown in the Central Valley.
Called “Growing the Valley,” the podcast will have a new episode every two weeks, with each episode focused on news growers can use, such as managing specific pests, irrigation techniques, alerts about what to watch out for, and what tasks to take care of at particular times of the year.
Proactive Pawnee Fire response in Lake County seeks to avoid another catastrophe
(SF Chronicle) Lizzie Johnson, June 25
“I've never seen so much focused attention in Sacramento on the issue,” said Keith Gilless, a professor of forest economics and dean of the College of Natural Resources at UC Berkeley.
“Last year, 2017, got everybody's attention,” said Gilless, chair of the California State Board of Forestry and Fire Protection. “Last year was just terrible. Everybody involved is doing their best to be as prepared as we can. Any area might burn now, including those with much higher structure densities than they did 20 or 50 years ago.
“You are going to need a lot of resources that you might not have needed before,” he said. “The state is being very aggressive in its suppression efforts.”

With vineyard labor scarce, Napa growers warm up to machines
(Napa Valley Register) Henry Lutz, June 24
On a recent morning at the UC Davis Oakville Experimental Station, extension specialist Dr. Kaan Kurtural walked along the edge of an especially tall block of Cabernet Sauvignon.
Planted in 2016, the block hosts 1,340 vines and produces roughly 15 to 18 pounds of fruit per vine. “So it'll be yielding quite nice,” Kurtural said as he walked down the 62-inch tall rows.
Far more notable than the vineyard's fruit, however, is how it gets farmed.
“There are no hand practices out here,” said Kurtural. “Everything is done by machine.”
Early Detection Key to Managing Ceratocystis Canker in Almonds
(Growing Produce) Dianne Munson, June 22
...Based on a statewide survey out of the Department of Pathology at University of California, Davis, canker diseases are the primary cause of tree death in almond orchards, and Ceratocystis canker is one of the most prevailing canker diseases found in California. This canker disease is aggressive, but it doesn't have to mean disaster.
“If you know what to look for, the disease is manageable,” says Florent Trouillas, UC Cooperative Extension Specialist, Department of Plant Pathology, University of California, Davis.
California has 27M more dead trees than in 2016, but numbers may be easing in some areas
(Ventura County Star) Cheri Carlson, June 22
“Trees aren't getting moisture that they need to be healthy and they're stressed,” said Susan Kocher, a natural resources adviser for UC Cooperative Extension. “We had a huge insect outbreak because of the drought.”
Kocher, based in South Lake Tahoe, focuses on the Central Sierra, where stands of ponderosa pines were hit hard by beetle attacks.
…The highest risk of fire is when trees still have their needles – the so-called “red and dead” phase, Kocher said. Green needles turn red, and those dried-out needles are a particularly flashy fuel, like tinder in a campfire. Once the needles fall off, the risk drops a bit.
Chinese scientists visit Tulelake
(Siskiyou Daily News) Danielle Jester, June 20
The University of California Agriculture and Natural Resources Intermountain Research and Extension Center in Tulelake hosted a group of scientists from Chinese universities on Sunday; the scientists are on a tour of agriculture in northern California through June 22.
University of California Vice President of Agriculture and Natural Resources Glenda Humiston explained the purpose of the tour, noting, “The Chinese face many of the same issues that we do here in the U.S. The Chinese universities want to improve rural economic development to lift up the quality of life for people in rural communities.
“They are also responding to global climate change, drought and pests while trying to improve food security and water use efficiency. They see UC Cooperative Extension as an effective research model; we hope that scientific collaborations will accelerate solutions and help maintain relations for California agriculture with China.”

With wildfire season at hand, California on slightly safer footing this year
(SF Chronicle) Kurtis Alexander, June 17
… But as significant, and plentiful, as the new fire-protection measures are, they merely nip at the edge of an underlying issue: that fire is a constant in California, and as long as people choose to live in and around the state's wildlands, experts say, the threat remains.
"I would not be surprised if we have another big fire," said Bill Stewart, forestry specialist at the University of California, Berkeley. "I just don't think we're where we need to be."
… “We really haven't put together the pieces of a resilient fire strategy in local areas,” Stewart said.
Reducing food waste to combat world hunger
(Morning Ag Clips) June 17
One-third of the world's food is spoiled or tossed rather than eaten, a fact that is tragic when nearly one billion people go hungry. The injustice of food waste is worsened by the fact that food decomposing in landfills emits greenhouse gases that contribute to climate change.
UC Cooperative Extension is working closely with the cities and county of Santa Clara in a far-reaching program to divert organic matter – food and green waste – from landfills by composting and using the product to enrich soil in the home garden.
From dendrometers to drones, devices drive ag-tech boom
(Farm Press) Tim Hearden, June 16
Agriculture across the country is going high-tech, and California is leading the way as the tree nut and other industries are looking for ways to save water.
Agriculture across the country is going high-tech, as the ag and food sectors invested $10.1 billion in digital technologies in 2017, according to a University of California study. That's up from $3.2 billion in 2016, reports the UC's Giannini Foundation for Agricultural Economics.
In California, which was the leading state last year with $2.2 billion spent to adopt new technologies in ag and food production, UC Cooperative Extension researchers are researching or developing lots of new, innovative ideas. And growers are putting them to work in their fields and orchards.

Overburdened growers fuel an ag-tech investment boom
(Western Farm Press) Tim Hearden, June 14
…While ag was slower than some other industries at adopting digital technologies, farm and food sector investments in these technologies zoomed to $10.1 billion nationwide last year, up from $3.2 billion in 2016, according to a new University of California report.
California was the leading state for ag-tech investments with $2.2 billion in 2017, or 22 percent of the total, and ag and food producers in the Golden State spent $5.1 billion on new technologies between 2012 and 2017, reports the UC Giannini Foundation for Agricultural Economics.
UCD Oakville Field Day Highlights: Trellis Trials, Red Blotch Vector Update, Mechanization Tools
(Wine Business) Ted Rieger, June 12
The University of California, Davis (UCD) hosted its annual Grape Day at the Oakville Station experimental vineyard in Napa Valley June 6 with talks and presentations by UC Cooperative Extension specialists, and presentations and equipment demos from vineyard industry suppliers.
UCD viticulture extension specialist Dr. Kaan Kurtural showed a trial planted in 2016 with six different trellis systems designed for mechanical harvest in a 1-acre block at the experimental vineyard using Cabernet Sauvignon 08 on 3309 rootstock. The six trellis types include: a traditional vertical-shoot- positioned (VSP) trellis as a control; a single high-wire system designed for mechanized management; a high-quad system; a cane-pruned system with 12-inch cross arms for a sprawl-type canopy; and two versions of a relaxed VSP, one with a T-top post for a wider canopy.

Why a Decline in Insects Should Bug You
(Wall Street Journal) Jo Craven McGinty, June 8
Entomologists want to put a bug in your ear: Insects are necessary for the survival of mankind.
“It's the classic third-grade food chain,” said Richard Redak, an entomologist at the University of California, Riverside, and co-author of the book “Bugs Rule!” “If you pull insects out, you've got a problem.”
…“Any organic product in a human's life probably has a beneficial insect and a pesty insect,” Dr. Redak said. “The pesty ones are an incredibly small fraction of the total. Those that are not a problem are critical to the ecosystem.”
Brown Marmorated Stink Bug Officially Deemed Pest of California Almonds
(Growing Produce) David Eddy, June 7
Brown marmorated stink bug (BMSB) is certainly not new to California growers, but in the wake of some more troubling finds, it is now officially a pest of almonds.
Almonds are now listed as a preferred host on the Stop BMSB website, which was created by a team of researchers from all over the country dedicated to finding a way to stop the pest from damaging a wide range of crops.
One of those researchers is Jhalendra Rijal, University of California Cooperative Extension Area IPM Advisor for San Joaquin, Stanislaus, and Merced counties, who said the first such damage was just two years ago, when they were found in peaches. The actual first finding in the state was three years before that, in Sacramento, but despite being a very large find, they never appeared to spread, adding to the mystery of BMSB movement.

7 Highlights from the 2018 World Meat Congress
(Pork) U.S. Meat Export Federation, June 4
The 2018 World Meat Congress concluded Friday with sessions focused on consumer trends and education, as well as an in-depth look at cutting-edge technologies reshaping meat production around the world. The 22nd World Meat Congress was held in Dallas May 31 and June 1. Hosted by the U.S. Meat Export Federation (USMEF) and the International Meat Secretariat (IMS), the event drew about 700 participants from more than 40 countries.
…The panel featured Gary Rodrigue, blockchain food trust leader for the IBM Corporation; Dr. Martin Wiedmann, Gellert family professor in food safety at Cornell University; and Dr. Alison Van Eenennaam, cooperative extension specialist for animal genomics and biotechnology at the University of California-Davis.
… Van Eenennaam, whose program at UC-Davis focuses on research and education around the use of animal genomics and biotechnology in livestock production systems, explained the value of gene editing. For example, research is underway to utilize gene editing to prevent such diseases as African swine fever in hogs and tuberculosis in cattle.
“What better way to approach dealing with disease than through genetic improvement?” she noted.

Physical dehorning of dairy cattle is a standard practice to protect both human dairy workers and other animals from injury. However, it is not only costly for producers, but also painful and stressful for the animals. As a result, dehorning is currently facing increased public scrutiny as an animal welfare issue. Despite these factors, 94 percent of U.S. dairy cattle producers report routine dehorning.
Early Ripening Grapes Could Revolutionize Raisin Production
(Growing Produce) Matthew Fidelibus, June 2, 2018
The USDA-ARS raisin grape breeding program has long focused on the development of early ripening varieties. Early ripening allows drying to begin sooner, thus helping to avoid inclement weather and enable production of dry-on-vine (DOV) raisins. ‘Fiesta' and ‘Selma Pete' are examples of early ripening raisin grapes from the USDA that have helped change the way California raisins are made.

Here's what trade tariffs could mean in Merced County, where nuts are big business
(Merced Sun-Star) Thaddeus Miller, March 28
China has threatened retaliatory tariffs on a select group of exports from the U.S. following President Donald Trump's plan to impose tariffs on steel and aluminum imports.
China's tariffs would first hit U.S. products such as avocados and nuts, with 15 percent duties. Beijing, if officials deemed it worthwhile, could also place 25 percent tariffs on American-made goods such as pork and aluminum.
…"It doesn't really matter which one it is, whether it's alfalfa, almonds or wherever it may go," said David Doll, a farm adviser with the Merced County UC Cooperative Extension. "They're as much political as they are anything else."
Nuts are big business in Merced County, where almonds are the second largest commodity at $578.5 million, according to the 2016 Merced County Crop Report, the most recent available. Almonds, pecans and pistachios bring in tens of millions of dollars more.
Out of every dollar made on a farm in the Central San Joaquin Valley, half pays for salaries and 40 cents goes to pay for supplies, Doll said, citing UC cooperative studies.
"Farms are businesses, and if they aren't profitable they're not going to stay in business," Doll said.

Scientists say regulation stifles many new biotech traits
(Agri-Pulse) Jim Weber, March 28
Federal regulation of agricultural biotechnology needs to be based on risk and not on process, a wide range of scientists and food industry executives agreed at the Agri-PulseAg and Food Policy Summit. Coincidentally, a similar message was delivered a day later by a Council on Agricultural Science and Technology (CAST) task force.
“Scientists have been screaming that for 30 years,” said Alison Van Eenennaam, a cooperative extension specialist in animal genomics and biotechnology at the University of California-Davis. “That's where regulation should be.”
…Although the USDA, universities and small businesses have developed dozens of GE crops – with improved traits ranging from healthier and less allergenic to safer and more environmentally sustainable – and carried many through safety and pre-market testing, almost all have been denied commercial release mainly because of U.S. regulatory obstacles,” according to the CAST task force, led by Alan McHughen, who chairs the Department of Botany and Plant Sciences at California-Riverside.
If China Strikes Back On Tariffs, California Tree Nut Exports Could Take A Hit
(CapRadio) Julia Mitric, March 27
California agriculture could find itself caught in the middle of the U.S. — China trade dispute.
After President Trump ordered a 25 percent tariff on imported steel and a 10 percent tariff on imported aluminum last week, China hit back, announcing it may impose a 15 percent tariff on agricultural exports from the U.S.
The U.S. faces competitors for every agricultural product it exports. California wines, for example, compete with wines from New Zealand and Chile. If China hits the U.S. with a 15 percent tariff on wine, that's a problem, explains Dan Sumner, Director of the University of California Agricultural Issues Center.
"We may think California wine is special, but not everybody does,” Sumner said. "And if it's 15 percent more expensive than it used to be because of the tariff, there'll be a substantial reduction in how much gets sold in China."

The agreement increases the academic, scientific, technological and cultural cooperation that are part of UC President Janet Napolitano's Mexico Initiative.
Building an IPM Program to Fight Fruit Flies
(Growing Produce) David Eddy, March 26
When faced with spotted wing drosophila (SWD), it's critical for growers to keep in mind this is almost certainly unlike any pest they have dealt with before. That's because it's one of two species — out of a potential 1,500-plus — that feeds on healthy, not rotting, fruit.
That's certainly not the end of growers' difficulties with SWD, says Jhalendra Rijal, University of California Cooperative Extension Area IPM Advisor, Northern San Joaquin Valley. It's tricky because vinegar flies — the tiny flies often found circling above fruit bowls on kitchen tables — are so ubiquitous. Even the oh-so-common name, “fruit flies,” indicates the pests' omnipresence.

Has the California dairy industry gone sour?
(Agri-Pulse) Tyler Ash, March 21 (Subscription only)
Rumors are circulating that a stampede of California dairy producers is heading toward greener pastures in other states. But why?
Experts in the nation's No. 1 milk-producing state have been ruminating on this dilemma for over a decade now, and it seems to stem from the same problems that are plaguing farmers all over America. Typical of the ag industry in general, mom-and-pop farms are going by the wayside and more large-scale farms are increasing production. So, the production seems to truck along but the number of players in that production does not.
“I remember being a kid, driving up I-5 and there were dairies all over the darn place,” said Jeff Stackhouse, livestock adviser for the University of California Cooperative Extension in Humboldt and Del Norte counties. “Now there's one.”
Statistics from the California Department of Food and Agriculture back him up. According to the agency, the state had 1,563 dairies in 2012 and four years later the number was 1,392, an 11 percent decline. The drop was 4 percent from 2015.
...Frank Mitloehner, professor of Animal Science at UC-Davis and a UC Cooperative Extension specialist, said California has lost approximately one fourth of its dairies over the last 15 years. His research focuses primarily on air quality related to livestock production and specified that the number of dairy cows in California hasn't actually decreased, just the number of dairies. He confirmed that most of the dairies that have closed were relatively small and weren't as competitive in today's market.
“The small ones often have a harder time in a strongly regulated environment,” Mitloehner said. “Large dairies generally hire some consultants to deal with air and water regulations to get their dairies to comply, but many small folks lack resources.”
According to Betsy Karle, dairy farm adviser for the University of California's Department of Agriculture and Natural Resources (UC ANR), the primary regulation that significantly affected California dairy producers was the General Order of Waste Discharge Requirement that was implemented by the Regional Water Quality Control Board in 2007, which affected approximately 1,400 dairies in California's Central Valley.
'Buy local' food programs deceive consumers and are rarely enforced, a USA TODAY Network investigation finds
(The Republic) Robert Anglen, March 20
As local-food sales grow into a $20 billion industry, a USA TODAY Network investigation found that state-branding programs designed to inform consumers and support local farmers are deceptive and virtually unregulated.
These "buy local" programs purport to connect shoppers with food from their states by affixing logos and stickers.
…"The word local is chic; it sells things," said Cindy Fake, horticulture and small-farms adviser for the University of California Cooperative Extension. "So it's used by everybody and anybody."
Fake said the word "local" has no clear definition and consumers are easily misled.
"They are likely to be deceived," she said. "Consumers are thinking one way and the marketers know that. They know consumers want local, so they say it's local."
… "There is a huge diversity across states about what is local," said Gail Feenstra, deputy director of the Sustainable Agriculture Research and Education Program at the University of California Division of Agriculture and Natural Resources.
Feenstra said there is more transparency on fresh produce because it's easier for consumers to identify where it came from and recognize regional products on store shelves.
But shoppers need to do their research, she said.
Roof Rat Damage Causing Concern for Growers
(AgnetWest) Brian German, March 16
Typically more of a problem in urban areas, roof rat damage is causing significant concern for farmers. According to University of California Agriculture and Natural Resources (UCANR) scientists, roof rats are appearing in considerable numbers this year. Researchers suggest monitoring fields for rodent activity and using bait stations before the growing season to prevent problems from developing further.
Valley farmers welcome rainstorms
(KFSN-TV) Reuben Contreras, March 15
Rain in the valley and snow in the Sierra from the last few weeks is adding to the water supply local farmers count on to grow their crops.
…"During the strawberry season if you have too much rain it is going to cause the fruit to rot," said Michael Yang of the UC Cooperative Extension Fresno County. "So during the full harvest, we don't want any rain."
Yang works with smaller growers in Fresno County. He says almost all of them rely on groundwater and wells to grow Asian specialty crops sold at farmer's markets.
Pedestrian Orchards Will Reduce Injuries
(California Ag Today) Jessica Theisman, March 14
California Ag Today recently spoke with Becky Phene with the University of California out of the Kearney ag center. She's working alongside Kevin Day, UC tree fruit advisor in Tulare County, on development of pedestrian orchards.
"My background is irrigation. I got asked to participate in the pedestrian orchard with Kevin because he wanted to demonstrate multiple technologies that would be beneficial not just now, but in the future,” Phene said.
Day has combined his pedestrian orchard with subsurface drip irrigation. The pedestrian orchards are by design kept short so that there is no usage of ladders. Eliminating the usage of ladders can help prevent on the job accidents.
“The pruning lets the tree grow quickly and fill in as quickly as possible in the first couple of years, and then he develops the shape of the canopy and the shape of the leaders,” Phene said.
Whole orchard recycling has promise for new almond plantings
Western Farm Press) Tim Hearden, March 14
When it comes time to push out old almond orchards, grinding them into the ground will improve soil nutrients for the next planting, a University of California Cooperative Extension researcher has concluded after years of studying the practice.
Whole orchard recycling increases soil organic matter and carbon, soil nutrients, and microbial diversity, leading to better productivity for the new trees planted in the old orchard's place, says Brent Holtz, pomology farm advisor in the UCCE office at Stockton, Calif.
California Almonds Are Back After Four Years of Brutal Drought
(Bloomberg) Alan Bjerga, Donna Cohen and Cindy Hoffman, March 14
After dropping during the drought, the 2017 almond crop rebounded to a record 2.14 billion pounds of shelled nuts. That's more than triple the amount of walnuts, the No. 2 U.S. nut, and more than four times that of pistachios, which are emerging as a serious competitor for California acreage. Almonds are “incredibly versatile,” said Daniel Sumner, an economist at the University of California, Davis. “And California is the best place to grow it. Where else can the weather be hot and dry and perfect, but you also have a system where you can bring water from mountains full of snow?” Almond-picking is also highly mechanized, which attracts farmers concerned about migrant-worker labor shortages, and its long history in the state creates a level of expertise competitors can't match, he said.

The What, When, and Why of Using Microbials on Your Farm
(Growing Produce) Robin Siktberg, March 12
Why should microbial controls be a part of an Integrated Pest Management (IPM) program? The first, and main one, is that research shows that they work. Many microbial products in the market today are backed by trial data that shows when used correctly, microbials can be a very effective way to improve plant health, suppress pest pressure, and improve yields.
“Microbials are very powerful tools,” says Dr. Surendra Dara, Strawberry and Vegetable Crops Advisor at University of California Cooperative Extension. “They have a number of benefits for the grower. Microbial control agents are either very specific (as with some viruses or Bt) or can attack a broad range of pests (as with fungi). They can have multiple modes of action, which prevents development of pest resistance. They are very safe for workers and consumers, and are a sustainable control option.”
(Fresno Bee) Robert Rodriguez, March 12
Roof rats, a common problem for city dwellers, are migrating to California farms and nibbling on everything from avocados to irrigation tubing.
University of California scientists say last year's wet weather created a perfect environment for the quick-breeding rats to flourish.
…"Rodents are everywhere and they are opportunists," said Rachel Long, a University of California, cooperative extension adviser. "They move in from their surrounding urban habitats to take advantage of any food source they can find. And once that food source disappears they search for food elsewhere."
Do Backyard Chickens Need More Rules?

…It was easy to welcome another chicken, partly because Oakland's local policies for keeping poultry aren't that restrictive. Roosters aren't allowed, and hens just have to be housed at least 20 feet from any house. That's it. No rules about the number of birds, their coops, slaughter or care. Bare-bones local laws around chickens are really common, says Catherine Brinkley, a veterinarian and urban planner at the University of California, Davis.
Brinkley says these policies tend to focus on limiting nuisances, like early morning cock-a-doodle-dos or eyesore coops — leaving a gap in codes when it comes to health and safety. "They're not at all focused on public health considerations, like [requiring] training for new owners in washing hands and selling eggs, nor do they think about if somebody is hoarding chickens or other awful things that, quite honestly, happen with animal welfare," Brinkley says.
OPINION Farm Bill must include climate change adaptation
(Redding Record Searchlight) Marty Walters, March 9
A new study published by a group of University of California researchers led by Tapan Pathak, published in the journal Agronomy, provides a whole new level of analysis in the ways that California's agriculture will change and be stressed by our changing climate, and it recommends ways to reduce some of the negative effects.
OPINION The self-inflicted economic damage to American agriculture
(The Hill) Daniel Sumner, March 9
Agriculture is so fully integrated into world markets that consumers everywhere take for granted that ripe peaches will be available to everyone, everywhere in January, while Zinfandel, Shiraz and Prosecco are universally available. Likewise farmers all over the world use tractors made in America, and tomato processors use equipment from Italy.
Study indicates that climate change will wreak havoc on California agriculture
(LA Times) Michael Hiltzak, March 9
The California we know is the breadbasket of the nation, producing more than two-thirds of the country's fruits and nuts, including almonds, pistachios, oranges, apricots, nectarines and prunes, and more than a third of its vegetables, including artichokes, broccoli, spinach and carrots. It's all valued at more than $50 billion a year.
Precise gene technology impacts GMO debate
(Capital Press) Tim Hearden, March 8
Precise gene-editing technology is bringing the debate over genetically modified crops into a new era, researchers and experts say.
While the use of GMOs has ignited a high-pitched public debate for years, the ethical and socioeconomic debate over the newer techniques “seems to be keeping pace with the science,” observes Neil McRoberts, a University of California-Davis associate professor and plant pathologist.
Trade war could spark food fight, California growers fear
(LA Times) Geoffrey Mohan, March 2
Steel and aluminum may be the intended quarry of a trade war that President Trump has said would be "good" for the U.S. economy, but the casualties of the conflict could be food, agricultural economists warn.
… No state has more at stake than California, which leads the country in agricultural revenue. Farmers and ranchers in the Golden State are twice as dependent on foreign trade as the country as a whole. World leaders also likely know that Trump enjoyed deep support in rural, agricultural areas, including much of the Central Valley, said Dan Sumner, an economist who directs the Agricultural Issues Center at UC Davis.
Shoes with rubber soles, western cottontail rabbits, birds, avocados, oranges, peaches, candy wrappers and fast-food cartons were among the contents that UC Cooperative Extension human-wildlife interactions advisor Niamh Quinn has found inside the stomachs of urban coyotes, reported Louis Sahagun in the Los Angeles Times.
Quinn is working with Cal State Fullerton graduate student Danielle Martinez to get a clear picture of what is sustaining coyotes that died across Los Angeles and Orange counties.
"This much is clear: coyotes aren't struggling in our urban environments," Quinn said. "They are almost everywhere, continually learning to adapt alongside us."
Quinn also developed the Coyote Cacher web application to catalog reports of coyote sightings throughout California. Users can see when and where coyote interactions occurred.
"Was howling at an ambulance going down PCH toward Hoag Hospital in Newport Beach," a report posted this month said.
"Killed and ate my cat," said another from the same area.
The stomach contents study indicates that cats make up only about 8 percent of the urban coyotes' diets. Dogs aren't part of the study because it would be difficult to differentiate the DNA of coyotes from other members of the canid family.
