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.

Answer to how urban coyotes thrive is not for weak-stomached
(Texarkana Gazette) From the LA Times, June 29
This scientific study is a coyote postmortem on an unprecedented scale—it has so far documented the contents of 104 stomachs and intends to examine 300 by the end of the year. The team, led by Niamh Quinn, UC Cooperative Extension's human-wildlife interactions advisor, is already generating a wealth of data to better understand how these omnivorous canids sample everything from pocket gophers to hiking boots while managing to survive in a land of 20 million people.
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.”
He demonstrated the 40-acre experimental vineyard during a recent field day at the UC-Davis Oakville Station north of Napa. About 200 winegrape growers, vineyard consultants, and other industry representatives attended.
Several methods available to control vineyard weeds
(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.”
UC's Humiston welcomes visiting Chinese ag scientists

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.
Santa Barbara County Avocado Farmer Struggles to Find Workers Amid Immigration Crackdown
(CNN Money/KTLA) Kristen Holmes, June 15
…“The crops that are most affected are the ones that use hired labor,” explains Daniel Sumner, director of the University of California, Agricultural Issues Center at UC Davis, pointing to avocados, berries and tree fruits. “It's really now through the rest of the summer that we're going to hear more and more farmers and farm workers rushing to get a harvest in with really not enough labor force to do it. And that's a real challenge. It may mean that we have crops rotting in the fields.”
Research Nets Going Over Citrus Trees To Prevent Huanglongbing Disease
(Cal Ag Today) Jessica Theisman, June 15
Beth Grafton-Cardwell is the director of the Lindcove Research Extension Center in Tulare County and research entomologist based out of the University of California, Riverside. She recently told California Ag Today that there is work being done on installing a net structure to protect trees from Asian Citrus Psyllids, which spread the deadly Huanglongbing disease. Texas A&M researchers are installing net structures on the edge of groves to block psyllids from coming into an orchard.
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.

(Progressive Dairyman) Alison L. Van Eenennaam and Maci L. Mueller, June 4
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.
Another chapter in California's unusual 2011 weather saga was added over the weekend when clouds dumped 1.64 inches of rain in Fresno, seven times the average for the month June, according to the Fresno Bee.
The story, written by Mark Grossi, said that the wet weather increases the potential for mold and mildew problems in vineyards. Growers may be applying additional treatments of mildew-fighting chemicals.
"Rain during this stage of the growing season is really unwelcome," the article quoted Matthew Fidelibus, UC Cooperative Extension viticulture specialist based at the Kearney Agricultural Research and Extension Center.
For farmers of other crops, the rain storm is a break from having to irrigate fields for a few days, agricultural officials told Grossi.
According to the Weather Channel website, the usual dry and warm weather pattern for June will soon resume. By Thursday, the valley high temperature is forecast at 90 degrees, about average for this time of year.
"All that we do know for certain is that a tremendously large population went into overwintering in fall 2010. So, if they survived, there could be a very large population emerging in the spring," the story quoted Tracy Leskey, a research entomologist at the U.S. Agriculture Department's Appalachian Fruit Research Station in Kearneysville, W.Va.
The stink bug will feed on almost anything, including cherries, tomatoes, grapes, lima beans, soybeans, green peppers, apples and peaches. When it feeds, it leaves behind an ugly spot that renders the fruit or vegetable unmarketable.
UC Cooperative Extension farm advisor Stephen Vasquez and viticulture specialist Matt Fidelibus warned of the new pest's potential to harm California grape crops in a post to their new Viticulture blog. They wrote that damage can be substantial when BMSB populations are not identified early and managed appropriately. Growers and wineries are also concerned that the “stink” from any bugs accidentally crushed in wine or juice grapes could taint the product with off flavors.
"One might define this thing as the bug from hell," U.S. Congressman Roscoe Bartlett told the Chron. "If I was a mad scientist doing gene splicing and putting together a bug that would really be nasty and I was turning it loose on my enemy, I probably couldn't do a better job."
The Chronicle said the best hope for farmers that have brown marmorated stink bugs is the insecticide dinotefuran, the active ingredient in the commercial products Venom and Scorpion. The chemical compound is labeled by the Environmental Protection Agency for use on vegetables, grapes and cotton, but not in orchards, as it is in Japan and other Asian countries.
More information about the BMSB and current research is available in a streamed PowerPoint presentation by USDA's Lesky posted on the web.
People involved in agriculture rarely complain about rain, but the latest series of winter storms has folks talking.
The San Joaquin Valley Viticulture Facebook page, maintained by UC Davis viticulture specialist Matt Fidelibus and Fresno County UC Cooperative Extension farm advisor Stephen Vasquez, reported on the drenching in the center of California.
"We've received more than two inches of rain at Parlier in the last 48 hours, and rain is likely for 7 of the next 10 days," read a post made at 4 p.m. on Monday.
Sacramento Bee reporter Loretta Kalb got commentary about the wet weather from the director of UC Cooperative Extension for Sutter, Yuba and Colusa counties, Chris Greer. He said the effects of this year's late-season soaking raised concerns for some row crops and tree crops. The wet ground will make it difficult to plant some crops such as rice during the traditional late April or early May schedule.
"If we don't get the ground dried out completely, it warms up, the weeds start growing, and they get a head start on the crop," Greer said./span>
