Wine grape growers in the San Joaquin Valley who want to switch from hand pruning to mechanical pruning won't have to replant their vineyards to accommodate machinery, according to a new study published in HortTechnology by University of California Cooperative Extension researchers. Instead, growers can retrain the vines to make the transition, without losing fruit yield or quality.
Mechanical pruning reduced labor costs by 90%, resulted in increased grape yields and had no impact on the grape berry's anthocyanin content. That's welcome news for growers because the cost of re-establishing a vineyard in the region is roughly $15,600 per acre.
“We found that growers do not have to plant a new vineyard to mechanize their operations,” said Kaan Kurtural, UC Cooperative Extension specialist in the UC Davis Department of Viticulture and Enology. “We have proven beyond a doubt that an older vineyard can be converted to mechanization. There is no loss in yield during conversion and post-conversion yield is better and fruit quality is equivalent to or better than hand-managed vines. The economies of scale are evident in the savings per acre and per vine as depicted in the balance sheet provided with the newly published paper.”
The research was conducted in an 8-acre portion of a 53-acre, 20-year-old Merlot vineyard in Madera County. After completion of the research project, the grower converted the rest of the 53-acre vineyard to single high-wire sprawling system. Many other wine grape growers have followed suit.
The Wine Group, which manages 13,000 acres of vineyards across Central California, is establishing new vineyards and converting old vineyards for mechanical pruning and suckering, said vineyard manager Nick Davis. Davis, who works closely with Kurtural and the UCCE viticulture advisor in Fresno County, George Zhuang, said the company greatly values the UC Cooperative Extension research that is guiding the changes.
“I think extensionists are undervalued,” Davis said. “We lean on them for applied research, which has been wonderful. They offer us what we can't provide ourselves.”
More than half of all California wine grapes are grown in the San Joaquin Valley. Worker shortages, rising labor costs, low returns and occasional droughts are driving wine grape growers to seek innovative ways to sustain their businesses.
“To help growers maintain the profitability of their vineyards, we're studying the use of machines to reduce the number of people needed to perform tasks like pruning,” Zhuang said.
“Because the canopy architecture and yield characteristics of mechanically pruned vines are different from vines that are hand-pruned, the water and fertilizer requirements for the mechanically pruned vines can be quite different. So we are studying the yield and fruit quality of grapes produced on different rootstocks in mechanical pruning systems in the San Joaquin Valley,” Zhuang said.
The Madera field study was conducted for three consecutive seasons in the hot climate conditions typical of the San Joaquin Valley. In this area, traditional vineyards are head-trained to a 38-inch-tall trunk above the vineyard floor and two eight-node canes are laid on a catch wire in opposite directions and two eight-node canes are attached to a 66-inch high catch wire. Although this traditional training system can work for mechanical harvesting, it doesn't accommodate mechanical dormant pruning and shoot removal with limited success in other mechanical canopy management operations.
To accommodate mechanical pruning and shoot removal, the vines were converted to a bilateral cordon-trained, spur-pruned California sprawl training system, or to a bilateral cordon-trained, mechanically box-pruned single high-wire sprawling system.
The latter option proved to be the most successful system for mechanical pruning in the San Joaquin Valley.

Landowners aim to fight fire with fire
(Benito Link) Blaire Strohn, March 19, 2019
The 2018 wildfire season in California was devastating, which left local landowners to consider how future blazes can be prevented. Their solution: more fire.
…UCCE livestock and natural resources advisor Devii Rao said the meeting also looked at Cal Fire funding and prescribed burn associations. She mentioned that last year former Gov. Jerry Brown signed two pieces of legislation related to prescribed burning:
Senate Bill 901 provides Cal Fire $1 billion for forest health, fuel load, and prescribed burns over five years, including $35 million a year for prescribed fire and other reduction projects.
Senate Bill 1260 requires Cal Fire to collaborate with public and private landowners on prescribed burns. They must also create a program for pre-certification for a “burn boss,” a private contractor that has experience in prescribed burning.
…In June, Rao will co-host a meeting with Lenya Quinn-Davidson and Jeff Stackhouse from UCCE Humboldt County. The meeting is expected to focus on how to develop a prescribed burn association, in addition to a small burn demonstration on a local private ranch.
A More Humane Livestock Industry, Brought to You By Crispr
(Wired) Gregory Barber, March 19
Hopes were running high for cow 401, and cow 401 serenely bore the weight of expectations. She entered the cattle chute obligingly, and as the vet searched her uterus, making full use of the plastic glove that covered his arm up to his shoulder, she uttered nary a moo. A week ago, Cow 401 and four other members of her experimental herd at UC Davis were in the early stages of pregnancy. But now, following a string of disappointing checkups, it was all down to her. Alison Van Eenennaam, the animal geneticist in charge of the proceedings, kept watch from off to one side, galoshes firmly planted in the damp manure, eyes fixed on a portable ultrasound monitor. After a few moments, the vet delivered his fifth and final diagnosis. “She's not pregnant,” he said. Van Eenennaam looked up. “Ah, shit,” she muttered.

US researchers moving abroad to avoid FDA's CRISPR-edited animal regulations
(Genetic Literacy Project) Cameron English, Alison Van Eenennaam, March 14
One day soon, farmers may be able to raise food animals immune to deadly diseases and spare them painful but necessary procedures like horn removal. These innovations, made possible by CRISPR and other gene-editing techniques, could cut the cost of food production, reduce antibiotic use in agriculture and dramatically improve animal welfare. But federal regulation may very well stifle these developments in the US.
In 2017, the Food and Drug Administration (FDA) proposed a plan to regulate gene-edited animals as veterinary drugs under the 1938 Food, Drug and Cosmetic Act, because their DNA is “intentionally altered.” The proposal has drawn harsh criticism from animal scientists, some of whom are packing up their labs and leaving the US to avoid the FDA's rules. Food animals, these experts say, should be regulated based on the risk they pose to human health, not the breeding method that produced them.
Corky Anderson's energy, innovation helped save California's pistachio industry
(Bakersfield Californian) Steven E. Mayer, March 13
"Corky was an important player in the early pistachio industry," said a Kern County farm adviser with the UC Cooperative Extension who specializes in citrus and pistachios.
"And he was a great cooperator," Kallsen said. "He allowed lots of test trials on his properties."
… In 1980, Anderson and Puryear's first patented rootstock changed the industry, said Kevin Blackwell, general manager of Pioneer Nursery, the wholesale business founded by the two entrepreneurs.
"In our heyday, we were selling a million trees a year," said Blackwell, who said he has known Anderson for 47 years.
No one does it alone, Kallsen noted. Anderson built and refined his patented rootstock based on earlier research by the University of California.
Farmers protect crops in rain's aftermath
(Ag Alert) Ching Lee, March 13
Franz Niederholzer, University of California Cooperative Extension farm advisor in Colusa, Sutter and Yuba counties, said though cold weather does reduce the risk of most fungal diseases, other problems such as bacterial blast and jacket rot—also a fungal disease—are more prevalent during cool weather.
Cooler weather, however, does help to extend the bloom, he said. That allows farmers more time to apply fungicide, which is recommended at the beginning of bloom and again at full bloom, he said.
Brent Holtz, UCCE farm advisor in San Joaquin County, said he hasn't seen too many problems with fungal diseases at this point, because of how cool it's been, but there have been more incidents of bacterial blast, which can infect trees under stress. In orchards with high nematode populations, the bacteria can enter wounds on the surface of the plants created by frost, he noted.
"It blights the blossoms, and if the blossom is dead, they don't produce fruit," Holtz said.

California's super bloom attracts swarms of migrating butterflies
(CNN) David Williams, March 13
This year's wildflower super bloom is not only filling California deserts with eye-popping displays of color -- it's also providing a feast for swarms of painted lady butterflies making their way north from Mexico.
"This is the biggest outbreak since 2005," said Art Shapiro, a professor at the University of California, Davis, who's been studying the migration of butterflies in the state since 1972.
…"I saw more butterflies in the last 10 minutes than I've seen my entire life," Jason Suppes wrote Tuesday on Twitter. Suppes is an education specialist at an agricultural research facility in Irvine.
Grape growers continue push to mechanize
(Western Farm Press) Lee Allen, March 13
…In Fresno, growers affiliated with the San Joaquin Valley Winegrowers Association met to discuss the latest UC research on incidents of disease and machine injury to trunks and rootstock.
… “Growers are having a hard time finding workers to maintain their vineyards and increasing labor costs are challenging grape-farming's economic sustainability,” says UC Cooperative Extension viticulture advisor George Zhuang. “We're studying the use of machines to reduce the number of people needed to perform tasks like pruning.
“Because canopy architecture and yield characteristics involving mechanically-pruned vines are much different from those that are hand-pruned, water and fertilizer requirements for the mechanically pruned vines can be quite different. Performance of different rootstocks in mechanical pruning systems is critical for both yield and fruit quality of grape production in the San Joaquin Valley.”
…Kaan Kurtural, UC Cooperative Extension viticulture specialist in the UC Davis Viticulture and Enology Department, whose research involves improving vineyard production efficiency through canopy and crop load management via mechanization, says the case for switching out hand labor with machines gets stronger with growers using such mechanization for pruning, suckering, and removing shoots and leaves.
“Mechanical pruning can produce more stable year-to-year fruit yields of better quality than traditional and more costly hand pruning spurs or canes.” His comments were based on a Kern County two-year research trial looking for ways for growers to reduce both cost and water use.

UC Davis, wine industry cultivate relationship
(Fruit Growers News) Robin Derieux, Feb. 13
Under the hot summer sun of the San Joaquin Valley, just south of Merced, Miguel Guerrero of The Wine Group is trying a new high-wire act. In collaboration with University of California-Davis Cooperative Extension, Roduner Ranch vineyard manager Guerrero is experimenting with Cabernet Sauvignon vines and other varieties elevated by a single wire at 66 inches – plantings that are 2-3 feet higher than the traditional winegrape canopy.
…“The beauty of the high-wire system is that the fruit zone is really defined – a solid wall of grape clusters – and the pruning machine can just zip right alongside the vines,” said Kaan Kurtural, a UC Davis Cooperative Extension viticulture specialist. “We can carry more crop, and with mechanical leaf removal, we get that sun-dappled exposure that feeds the fruit. Less leaf cover means the vines require less water, and the grape quality is much better.”
There's Still So Much We Need To Learn About Weed—And Fast
(Wired) Matt Simon, Feb. 11
… But late last month, UC Berkeley opened the Cannabis Research Center to start tackling some of these social and environmental unknowns. With its proximity to the legendary growing regions of Northern California, the center can start to quantify this historically secretive industry, measuring its toll on the environment and looking at how existing rules affect the growers themselves. The goal is to create a body of data to inform future policies, making cannabis safer for all.
… So for the past few years Van Butsic, codirector of the Cannabis Research Center, and his colleagues have been sifting through satellite images to pinpoint those unaccounted-for farms. “We have an army of undergraduates who look at high-resolution imagery and digitize how big the farms are, how many plants we can see,” Butsic says. Because cannabis plants love light, growers usually keep them out in the open. The researchers still miss many trespass growers, however, who tend to hide their plants in the brush to avoid detection.

By the time you see broomrape weed in your fields, it may be too late. There has been a resurgence of broomrape reports over the last decade in California. Retired UC Cooperative Extension Farm Advisor Gene Miyao said although the parasitic weed is far from widespread, it could become so quickly. “The seeds are very small, the growth is primarily underground until it starts sending up shoots and then it very quickly starts setting seed,” he said. “A single seed attached to a tomato plant may send up half-a-dozen shoots, and each shoot might have 1,000 seeds or more.”
New CA Bill Aims to Help Prepare Farmers for Extreme Weather, Changing Climate
(YubaNet) CalCAN, Feb. 7
The state and University of California have made significant investments in research to better understand agriculture's unique vulnerabilities and adaptation strategies to a changing climate, including in the state's recently released Fourth Climate Change Assessment. But not enough has been done to translate climate risks to the farm level and assist farmers in adapting to climate change.
…The bill would also fund trainings for technical assistance providers and agricultural organizations. According to a 2017 survey of 144 University of California Agriculture and Natural Resources staff, 88% of respondents believe it is important to incorporate climate change information into farm extension programs, but only 43% actually do. Respondents cited a lack of access to climate information relevant to farmers and expressed interest in education on technical tools and information resources.

On Feb. 19, San Joaquin Valley grape growers are invited to discuss the latest UC research on mechanical pruning, trunk disease and rootstocks with UC Cooperative Extension advisors and specialists in Fresno. Growers will also get to observe a field demonstration of grapevines being mechanically pruned.
“We have been hearing from California grape growers that they are having a hard time finding enough workers to maintain their vineyards and increasing labor cost starts challenging grape-farming economic sustainability so we are studying the use of machines to reduce the number of people needed to perform tasks such as pruning,” said George Zhuang, UC Cooperative Extension viticulture advisor for Fresno County.
Gabriel Torres, UC Cooperative Extension viticulture advisor for Tulare and Kings counties, will discuss plant diseases that may result from trunk injuries and pruning wounds from the machinery.
Karl Lund, UC Cooperative Extension viticulture advisor for Mariposa, Merced and Madera counties, will discuss how to select rootstock for a vineyard that will be mechanically managed.
“Because the canopy architecture and yield characteristics from mechanically pruned vines are much different from hand-pruned vines, the water and fertilizer requirements of mechanically pruned vines can be quite different,” Zhuang said. “Therefore, performance of different rootstocks under mechanical pruning system is critical to achieve both yield and fruit quality targets of grape production in the San Joaquin Valley.”
Kaan Kurtural, UC Cooperative Extension viticulture specialist in the UC Davis Department of Viticulture and Enology, will go over the basic principles of mechanical pruning of wine grape vines.
From 8 a.m. to 10:30 a.m., UC Cooperative Extension advisors and specialists will meet with growers in a Golden State Vintners vineyard at 7409 W Central Ave in Fresno.
“We will discuss current grape issues and the future of viticulture in the valley,” Zhuang said.
The meeting, which is being co-hosted by UC Cooperative Extension and San Joaquin Valley Winegrowers Association, is free. For more information, contact Zhuang at email@example.com or (559) 241-7506.
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.

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.”

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.”

(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.

… 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.
Use of gene editing to introduce the polled trait into elite germplasm
(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.
