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."

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.”

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

Eighty-one years from now, Turlock's climate could resemble more of southeast California's high desert areas, according to a new report that says inland California municipalities should consider increasing temperatures due to climate change when planting street trees.
…"Urban foresters in inland cities of California should begin reconsidering their palettes of common street trees to prepare for warmer conditions expected in 2099 due to climate change," said the study's co-author, Igor Lacan, UC Cooperative Extension environmental horticulture advisor in the Bay Area.
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.
Researchers look at ways to improve onion yields
(Ag Alert) Padma Nagappan, Aug. 1
Jairo Diaz-Ramirez and five other scientists have recently completed year two of an irrigation trial for onions, testing furrow and drip irrigation, and found that their methods produced good results, without water distress or soil tension. They tested the Taipan variety of onions.
Commercial and backyard poultry owners are asked to be attentive to their animals' health to help prevent the spread of the lethal and contagious virulent Newcastle disease now raging in Southern California, reported Bob Rodriguez in the Fresno Bee.
Symptoms of the disease include sneezing, coughing, green watery diarrhea, neck twisting, paralysis, decreased egg production and swelling around the eyes and neck, according to Maurice Pitesky, UC Cooperative Extension poultry specialist.
He said the popularity of backyard chickens is one of the challenges to controlling the disease. He estimates there are about 100,000 homes with poultry, with each home averaging five chickens.
"That is a lot more than in 2002, when we had the last outbreak (of virulent Newcastle disease)," Pitesky said. In 2002, the disease started in a backyard flock and eventually spread to 22 commercial poultry farms, killing 3.2 million birds.
"While people have the best of intentions, unfortunately a lack of biosecurity practices in people's backyards is one of the contributing factors of the disease spreading," Pitesky said.
Birds can become infected by coming into contact with other birds that are carrying the disease or by humans that carry the disease in their clothes or shoes. Pitesky said the disease also spreads when people purchase birds from a private party who may not be able to verify the bird is disease free.
He recommends buying from a hatchery or feed store that is affiliated with the National Poultry Improvement Plan, an organization that focuses on disease control.
“The goal is to be preventative,” Pitesky said.
If backyard chickens appear ill, owners should call the California Department of Food and Agriculture's State Bird Hotline at (866) 922-2473.
For more information on the disease, see the Virulent Newcastle Disease Outbreak Information and Resources page Pitesky has posted to his website, UC Cooperative Extension Poultry.

The late winter freeze caused significant issues for several different commodities throughout the state and has been especially problematic for the California olive crop. The fluctuating temperatures have created substantial concern among the industry as bloom looks to be far below normal levels.
“Overall we're a little on the pessimistic side. The bloom, on the whole, has been pretty poor, many orchards actually have a very light, to next to no bloom at all,” said Dani Lightle, Cooperative Extension Orchard Systems Advisor for Glenn County. “There's an orchard here or there that looks pretty good, but on the whole, it is a little bit dismal.”

In short, he is working on breeding the perfect avocado that tastes great and is easier, faster, and less water-dependent to grow. This year is shaping out to be a good one for avocados, but this issue is always one to keep in mind.
Focht states that in the future, there will likely be more variety available in the mainstream marketplace. One varietal that Focht gets excited about is the Reed avocado which has now been popping up in places such as Whole Foods. It's known for its round, dinosaur egg shape and is about the size of a softball. It has a relatively large seed but the edible flesh is sometimes double or even triple that of a Haas that can make a lot more people happier per individual fruit.
(Chico News & Review) Ashiah Scharaga, May 24
When drifting clouds dapple the sky and vibrant wildflowers—tickled pink buds, honey-hued petals and virent stems—awaken in the verdant fields of Table Mountain, explorers quicken their pace. They spot trickling streams and grazing cattle. Occasionally, they look straight down, turning anxious eyes to their mud-slicked heels—did they step in one of the fertile cow-pie mines littered across the landscape?
That may seem a nuisance, but it's a necessity. Tracy Schohr, a livestock and natural resources adviser for University of California Cooperative Extension, said the natural magic of the popular Butte County recreational spot is made possible because of a long-standing grazing program. “If cattle were not actually on Table Mountain Ecological Reserve,” she said, “essentially those invasive species would choke out those native plants, and they wouldn't be there.”
… In the past, grazing was misunderstood and primarily viewed as destructive, said Dave Daley, a fifth-generation Butte County cattleman and associate dean of Chico State's College of Agriculture. He credits changing perspectives to the development of grazing science, fueled by people such as Schohr and Kate Wilkin, a UC Cooperative Extension forestry, fire science and natural resource adviser for Butte, Yuba, Sutter and Nevada counties.

Sheep Shearing 101: Why Aspiring Shavers Flock to This California School
(KQED) Tiffany Camhi, May 23
…“We try to get the students shearing the first day because they make a lot of mistakes,” says John Harper, head of the UC Cooperative Extension Sheep Shearing School in Hopland.
Harper says if you can make the right moves with your feet, everything else falls into place.
“We're dancing instructors,” says Harper. “It's like 'Dancing With The Stars' on steroids, but with sheep.”
Around this time of year, hundreds of thousands of sheep in California need to have their wool shaved off. But Harper says there's a shortage of sheep shearers worldwide.
That's why he started the school in Hopland about 25 years ago.
Dan Macon of the California Wool Growers Association says the growing popularity of backyard flocks in California (usually just a handful of sheep) is adding to the demand for shearers, too.
“Infrastructure of the sheep industry is a key component,” says Macon. “Having people with that kind of skill and willingness to work hard is desperately needed.”
AUDIO: Hey, Salad Lovers: It's OK To Eat Romaine Lettuce Again
(NPR Morning Edition) Allison Aubrey, May 23
…After a big foodborne illness outbreak linked to baby spinach back in 2006, the leafy greens industry put in place a number of procedures to prevent contamination. "Prevention became the major focus after that outbreak," says Michele Jay-Russell, a food safety researcher at the University of California, Davis.
"They set up intensive testing protocols to monitor water quality," Jay-Russell says. The industry also agreed on standardized setbacks — or buffers — to separate growing fields from livestock operations, which can be a source of E.coli contamination. "You want a safe distance from where you're growing fresh produce and where you have concentrations of animals, like on a feedlot or dairy," she says.
Are avocados toast?
(Grist) Nathanael Johnson, May 22
…When Katherine Jarvis-Shean was a doctoral candidate researching the decline of cold winters a few years back, she thought more farmers should be freaking out. “I used to think, ‘Why aren't you guys more worried about this? It's going to be the end of the world.'”
After all, many fruit and nut trees require a good winter chill to bear fruit. But after spending a few years as an extension agent for the University of California — working directly with farmers and translating science into techniques they can apply on the land — she understands better. It comes down to this: Farmers have a ton of concerns, and the climate is just one of them.
“If you decide what to plant based on climate, but then can't make the lease payment, that's not sustainable,” Jarvis-Shean said.
Lanternflies Eat Everything in Sight. The U.S. Is Looking Delicious.
(New York Times) Zach Montague, May 21
…Native to Asia, lanternflies first appeared in Pennsylvania in 2014. Despite a quarantine effort, they have also been discovered in small numbers in New York, Delaware and Virginia.
… “Most pests deposit their eggs on their host plant, or very close, so they already have food available,” said Surendra Dara, an adviser at the University of California Cooperative Extension.
“Those that have the advantage of being able to lay eggs on non-plant material obviously have a better chance of surviving and spreading,” he added.
Garbanzos are catching on in Yolo County
(Woodland Daily Democrat, Ag Alert) Bob Johnson, May 19
…“The largest part of our crop goes to canning, maybe 90 percent,” said Paul Gepts, UC Davis plant sciences professor and legume breeder. “California can only compete with high quality products. We have other varieties with higher yields, but the seeds are too small. The growers get a premium for larger, high quality seeds.”
Gepts developed the two newest UC garbanzo varieties, Vega and Pegasus. Both have large, attractive seeds well suited for the canning market, and both have resistance to Ascochyta blight, a fungal disease that can devastate the crop.
… “I think growers are more interested in garbanzos because it's a winter crop, and wheat prices are low,” said Rachael Long, UC Cooperative Extension farm adviser in Sacramento, Solano and Yolo counties. Long is finishing up UC's first Garbanzo Production Manual, which should be available before the end of the year.

Even by the standards of the Bay Area, where sourcing local, organic chicken feed is seen as something of a political act, the spectacle of 30,000 fruit and nut trees being tended by formerly incarcerated orchardists is novel.

Machines take over for people at Napa vineyard
(Capital Press) Tim Hearden, May 14
In the heart of the Napa Valley, a vineyard produces fine Cabernet Sauvignon with virtually no help from laborers.
The 40-acre “touchless vineyard” was established by Kaan Kurtural, a University of California Cooperative Extension specialist who has devoted much of his career to improving production efficiency in vineyards as labor shortages have worsened.
…When Kurtural started experimenting with vineyard automation 10 years ago, his primary goal was to save growers money in labor costs, he said. But since then, research has shown that grape quality is superior, largely because the tall canopy protects grapes from sun damage, he said. The system also uses less water than others, he said.
Dozens of strawberry growers gather in Santa Maria to learn latest industry advancements
(KSBY Staff) May 9
More than 100 farmers and growers took park in a meeting teaching them on the best way to grow a healthy strawberry.
The University of California put on the annual event which was free to the public.
Growers discussed improvements handling weeds, disease, and insects.
The Santa Maria Valley is the second largest strawberry growing area in California after the Salinas Valley.
The crop means a lot to people in Santa Maria.
"We've got a number of challenges to the California strawberry industry and we're doing are best to work together," said Steven Fennimore of University of California Cooperative Extension Agriculture and Natural Resources. "I'm optimistic that we'll find some satisfactory solutions."
Growers talked about all kinds of different ways to boost their crop including ways of using images from aircraft to detect stress in plants.
Pesticide Use on California Farms at Near-Record Levels
(Fair Warning) Paul Feldman, May 9
…Some experts say long-term changes in the mix of items farmers produce in California, including increases in almonds and other high value crops, give the agriculture industry the incentive to use more pesticides. Such crops present “a larger economic risk if pests are not controlled,”said Brad Hanson, a weed specialist at the University of California, Davis, plant science department.
Jim Farrar, director of the University of California's statewide integrated pest management program, added that more pesticides are needed when “you move from something like alfalfa and sorghum for dairies, where cosmetic injury isn't a problem … to something like oranges where if there's a blemish on the rind you get downgraded even if the orange is perfectly healthy.”
Cherry growers expect lighter crop yields
(Ag Alert) Ching Lee, May 9,
…Kari Arnold, a University of California Cooperative Extension farm advisor in Stanislaus County, said she's careful not to paint the 2018 cherry season as a disaster year "because it's really not." The crop may not be as robust, she said, but this was somewhat expected, because last year's crop was so big.
What wasn't expected, she said, was the freeze in the spring, which "did cause some damage to flowers." But the damage varied depending on the location of the orchard and whether growers were able to apply frost protection, she added.
"It's still going to be a good crop," she said. "It may not be the same as last year, but they're going to be good cherries. They're probably going to sell at a higher price because there'll be less of them."
She said she's concerned that word of it being a light crop may scare away field help, adding that "it's hard enough to get field labor in the first place anymore, because labor is becoming more and more difficult to come by and more difficult to keep."
Peak Avocado Is Yet to Come
(The Atlantic) Cynthia Graber, Nicola Twilley, May 9
…Its partners in evolution—the giant, elephant-like gomphotheres and three-ton ground sloths that dined on its fruit in return for transporting and then pooping out its giant seed—went extinct soon after the first bipedal apes arrived in the region. Rodents, jaguars, and eventually humans stepped in as dispersal mechanisms, albeit significantly less effective ones. The flourishing avocado forests that carpeted much of Mesoamerica dwindled and died out. And, as Mary Lu Arpaia, who runs the avocado breeding program at the University of California at Riverside, explained, the avocado became a backyard fruit, enjoyed by first the indigenous peoples and later the conquistadors, but rarely cultivated intensively—until recent decades.

More illnesses with later onset dates linked to romaine outbreak
(The Packer) Ashley Nickle, May 8, 2018
Richard Smith, a University of California Cooperative Extension advisor based in Salinas, also said the outbreak is hurting sales.
“It's having an effect,” Smith said May 7. “This is the problem — lettuce is pretty expensive to grow, and you've got to cover your costs. You can lose money, at this point the bigger growers can afford to lose for a period of time, but then they've got to make it up, and it just makes it hard. We're not sure how the year's going to go.
“I guess the good news is that the consumers are being sophisticated enough to be focusing on the romaine (versus all lettuce) ... The reality is I guess the FDA doesn't want to clear romaine yet because they think that the lettuce from Yuma might have a 21-day shelf life, so until the FDA clears it and then that news gets clearly articulated, I think it's going to be a damper.
AEI economists say farmers have ‘beef' with Trump
(Hagstrom Report) May 7, 2018
…Daniel Sumner of the University of California at Davis also told The Hagstrom Report that farmers hurt by the administration's trade policies have "a beef" with Trump.
Sumner said that even though the tariffs on Chinese steel and aluminum have not yet gone into effect, California farmers including wine and almond producers are already worried. "Even if the tariffs don't happen, the rhetoric has effects," he said.
Sumner also said that Mexican buyers of U.S. dairy products — "reasonable business people in Mexico" — began months ago to contact New Zealand dairy producers about becoming a supplier because the Mexicans are worried about the impact of the North American Free Trade Agreement renegotiation.

Egg prices plunge as supplies rebound
(Capital Press) Tim Hearden, May 4
Commercial egg prices in California are plummeting, and a slow global economy combined with a rebounding chicken flock after last year's devastating avian flu outbreak are among the contributing factors.
…At first, Midwestern egg producers that didn't want to retrofit their barns simply avoided California. Those that did want to market to California found confusion in what actually constituted a Proposition 2-compliant cage, said Joy Mench, a University of California-Davis animal science professor.
“(T)he wording of Prop. 2 does not allow it to be regulated, so there is no official definition of what it means,” Mench said in an email. “That will have to be decided in the courts, either because there is a lawsuit or because someone is prosecuted.”
In enforcing the initiative, the CDFA uses the federal Shell Egg Food Safety rule, whose space requirement is larger than the United Egg Producer guidelines that most of the other states use, noted Maurice Pitesky, a poultry specialist at the UC-Davis School of Veterinary Medicine.
Farming takes center stage at Yolo County Fairgrounds
Woodland Daily Democrat) Cutter Hicks, May 4
Field trips to the fairgrounds led to a farming experience for students as the Yolo County 4-H and Farm Bureau hosted its 10th annual Farm Connection Day to kick off the Spring Show this weekend.
The four-hour event Friday featured more than 100 agricultural displays and hands-on activities for kids of all ages as nearly 2,500 visitors walked through the gates.
Farm Connection Day was open to the public and more than 200 4-H students teamed up to host the event — with a little help from adult volunteers. Their focus was to teach students of Yolo County the aspects of the organization before judging shows later that day.
DeAnn Tenhunfeld, a Farm Connection Day organizer, said that the attendance was the largest seen since she founded it in 2008.
Frost damage varied for California nut trees
(Farm Press) Robyn Rominger, May 2, 2018
Some almond growers experienced frost damage from recent freezing conditions, say University of California experts.
“There's really a lot of damage,” says Katherine Jarvis-Shean, UC Cooperative Extension orchard systems advisor for Sacramento, Solano, and Yolo counties. “The earlier varieties really took a hit. Some trees even dropped their nuts due to frost damage. It's pretty bad in some orchards.”
… Bruce Lampinen, UCCE almond and walnut specialist, measured temperatures in an almond trial at Davis, and notes that “Feb. 20 and 24 were the coldest days. It was very problematic because that's when the trees were in full bloom.” At full bloom, temperatures below 28 degrees F. can cause crop loss.
…Phoebe Gordon, UCCE orchard systems advisor for Madera and Merced counties, says, “From what I've seen and heard, the damage has been variable. Some orchards weren't hit that hard, and others were hit very hard. I think it depended a lot on micro-climate and what stage the trees were in. They become more susceptible to frost damage as they transition from dormant to full bloom, and to nut set. I don't think we'll really know until ‘June drop' is finished what the final load is.”
Dani Lightle, UCCE orchard systems advisor in Glenn and Butte counties, says, “Almonds were right in the middle of full bloom when the frost happened. Most of the orchards in my area seem to have escaped. We didn't seem to cross the threshold to where there was heavy damage. Of course, there are exceptions, but by and large we came out better in the end than we thought we would.”
New weapon in fight against walnut blight
(Farm Press) Robyn Rominger, May 2, 2018
Walnut growers have a new tool to help manage blight disease in their orchards — Kasumin 2L, manufactured by Arysta LifeScience, is the trade name for kasugamycin, and is available as part of a strategy to control the disease.
The new bactericide was discussed at a recent University of California Cooperative Extension breakfast meeting at Yuba City. “It's great to have another chemistry in the rotational loop for blight management in walnuts,” says Emily Symmes, UCCE integrated pest management advisor.

What a nutritionist wants you to know about pesticides and produce
(NBC News) Samantha Cassetty, April 15
This week, the Environmental Working Group (EWG) released an update to their annual Dirty Dozen and Clean 15 lists. These lists reveal produce with both the highest and lowest levels of pesticide residue, according to their methodology. The report looks more or less the same as last year's guide, with strawberries claiming the unfortunate number one spot, edging out spinach and nectarines.
… But let's get one thing clear: Organic produce is not pesticide-free. There are pesticides used in organic farming, but they're derived from natural substances rather than synthetic ones, And as Carl Winter, Ph.D., Extension Food Toxicologist and Vice Chair, Food Science and Technology at University of California, Davis puts it, in either case, “the dose makes the poison.”
OPINION: Should California Winemakers Be Worried About China's Tariffs?

At the April 6 Joint Information Hearing of the California State Senate Select Committee on California's Wine Industry and the California Assembly Select Committee on Wine the overarching theme of the meeting was: “We are open for business.” While there are impacts from the October fires, the message went, stories of our demise are greatly exaggerated. So come on down for your corporate event, wine tasting weekend, wedding or bachelorette party.

McGourty discussed some of the scientific advances being brought to bear for assisting the wine industry with its water usage, including surface renewal technology, which will tell a grower exactly how much and when to irrigate and could save 50 to 100,000 gallons of water per acre, using crop cover on the soils, which allows soil in one acre to hold an additional 38,000 more gallons of water, and various ways to control frost in vineyards so that irrigation isn't needed to prevent frost.
County program to cull dead trees continues
(The Union Democrat) Alex Maclean, April 5
Scientists doing field-based research saw a decline in the death rate of ponderosa pines from western bark beetle infestation last year, but Tuolumne County isn't slowing down its effort to help landowners affected by the drought-induced epidemic.
… Jodi Axelson, a Cooperative Extension specialist in forest health at University of California, Berkeley, said the slowing of mortality seen over the past year should give counties like Tuolumne an opportunity to catch up on removing dead trees from private property.
Axelson is part of a team of scientists collecting data on tree mortality that also includes John Battles, a forest ecology professor at UC Berkeley, and Susie Kocher, a natural resources advisor for UC Cooperative Extension, Central Sierra.
Land suitable for certain California crops expected to shrink
(Agri-Pulse) Steve Davies, April 5
California growers should start to look seriously at how to adapt to a changing climate, which could shrink the land available for many of the state's most popular crops, a new study has found.
“Reduced numbers of chill hours, increased pest pressure, increased water demand and water-induced stress, as well as variable and unreliable water supply, are examples of factors that are projected to adversely impact the yield and quality of various crops grown in California,” says the paper, published in the journal Agronomy. Chill hours are traditionally defined as those periods where the temperature is below 45 degrees Fahrenheit.
"Understanding climate change and how it is impacting agriculture can help us develop relevant adaptation strategies and enhance agricultural resilience to climate risks," said lead author Tapan Pathak, a cooperative extension specialist at the University of California Division of Agriculture and Natural Resources.
Search for wine ‘smoke taint' solutions intensifies after Northern California wildfires
(North Bay Business Journal) Jeff Quackenbush, April 4
The international pursuit of ways to predict how much smoke from a wildfire will end up in finished wine and what to do about it got a boost when the dark clouds of particles pumped out by the massive North Bay fires in October descended on the University of California, Davis, experimental vineyard in Napa Valley.
“The moment the smoke started, my phone started ringing off the hook,” said Anita Olberholster, Ph.D., a specialist in the science of winemaking for University of California Cooperative Extension. When the fires erupted Oct. 8, most of the North Coast winegrape crop had been picked, but some late-ripening fruit, particularly cabernet sauvignon was still on the vine, in the home stretch of the 2017 harvest. “It quickly realized how thin the data is I need to base recommendations on.”

UC Climate Video Questioned by UC Researchers
(UCD Aggie) David Madey, April 4
According to a video called “The diet that helps fight climate change” released by the Office of the UC President, everyone — including the 238,000 students across the UC system — can help combat climate change on their own. But not everyone is celebrating.
… “[The video] recommended for the global population a diet that only the top one percent can afford,” said Dr. Frank Mitloehner, a professor and air quality specialist at UC Davis. “We could not even satisfy a Mediterranean diet for the entire United States population today.”
… Dr. Glenda Humiston, the vice president for the UC Division of Agriculture and Natural Resources, wrote in a public letter to UC colleagues, “[The video] states that if the world was to reduce its meat consumption, that decision alone could offset the emissions from a billion cars on the road by 2050. For the U.S., however, this contention is misleading, as the impact would be considerably smaller.”
Dr. Alison Van Eenennaam, an expert featured in “Food Evolution” from UC Davis, also claims that the Climate Lab video is misleading. With a combined 2.1 million views on YouTube and Facebook to date, Van Eenennaam expressed concern that the public is led to believe that diet is twice as important as transportation effects –– which is not true at all, she said.
“It's not simple, and that video made it simple,” Van Eenennaam said.

Drought put UC's water-saving strategies into practice
(Western Farm Press) Tim Hearden
The historic drought from 2012 to 2016 forced almond growers to put into practice water-conservation strategies they'd been taught by University of California Cooperative Extension crop advisors — so say a farmer and an advisor in a newly released video on water management.
Raj Meena of the Gustine, Calif.-based Meena Farms, says tools such as the pressure chamber, which measures water stress in trees, and soil moisture monitoring helped the operation survive drastic cutbacks in water. “I would say our water management improved considerably because it had to,” he says in the video, part of series on drought tips from the UC California Institute for Water Resources. “If we hadn't done that, we wouldn't still be farming. When you're so regulated in the water that you have, you have to allocate it very carefully.”
UC program aids in citrus disease fight
(AgAlert) Christine Souza
At war with the Asian citrus psyllid since it was found in San Diego County in 2008, California citrus growers and packers have had unprecedented success in slowing the spread of the tree-killing bacteria the psyllid can carry. People in the citrus business say part of that success relates to the testing and distribution of clean citrus plant material through the University of California, Riverside.
The Citrus Clonal Protection Program at UC Riverside tests clonal material to ensure that citrus varieties introduced into California remain free of pathogens.
Joel Nelsen, president of California Citrus Mutual, said he believes work such as that done by the program has helped defend California citrus from the tree-killing bacterial disease huanglongbing or HLB, also called citrus greening.
California fights costly battle against invasive species
(Agri-Pulse) Tyler Ash
Every year, California acquires on average nine new invasive species, including exotic insects, spiders, mollusks and even South American mammals. Three of those invaders usually try and settle down, start a large family and stake a claim on some of the Golden State's endless buffet of agricultural crops, becoming the bane of farmers and researchers.
“There are lots of species that get here and don't become established, it's just a few that do,” said Jim Farrar, director of the Statewide Integrated Pest Management Program of the University of California Division of Agriculture and Natural Resources.
According to the UC-Riverside's Center for Invasive Species Research, invasive pests cost the state an estimated $3 billion a year. Intrusive plants alone cost California at least $82 million annually for control, monitoring and outreach, not including crop loss, as reported by the California Invasive Plant Council.
UC Davis researchers on a hunt for backyard chicken eggs around the Thomas Fire burn scar
(Ventura County Star) Cheri Carlson, April 3
Veterinarians at UC Davis have put out a call for eggs from California's backyard chicken owners, particularly those living near the Thomas Fire and other recent blazes.
They want to test the eggs for free in an effort to understand how they might be affected by wildfires, lead and other environmental factors.
It's called the Backyard Chicken Egg Study. And, they need help from backyard chicken enthusiasts, said Maurice Pitesky, a faculty member at the UC Davis School of Veterinary Medicine-UC Cooperative Extension.
“We're trying to understand the connection between the environment and our backyard chickens,” said Pitesky, who teamed up with colleague Birgit Puschner to test the eggs.
