How One Entomologist Found His Calling as an IPM Facilitator
(Entomology Today) Lina Bernaola, April 18
Alejandro Del Pozo-Valdivia, Ph.D., is currently an IPM entomology advisor at the University of California Cooperative Extension. He serves the vegetable industry in the Central Coast region of California by conducting applied research on pest management and implementing an extension program for stakeholders.
Alejandro was born and raised in Lima, Peru, where he earned his bachelor's degree in agronomy from La Molina National Agrarian University. Then, he went to Washington State University, where he obtained his master's degree in entomology working on integrated pest management (IPM) in irrigated hybrid poplars. In 2016, he obtained his Ph.D. in entomology at North Carolina State University (NCSU). During his doctoral studies, he worked on proposing management practices for the kudzu bug, an invasive pest of soybeans.
America's leading animal geneticist wants to talk to you about GMOs
(Pacific Standard) Emily Moon, April 18
At 11 a.m. on a Thursday morning, Alison Van Eenennaam is sitting in a harshly lit lab room, surrounded by her graduate students, talking about cattle sex—sex that, unfortunately, has not gotten anything pregnant. With the gene-editing techniques she's using, there could be many factors to blame: the location in the DNA strand of the edit, the biopsy performed to check the results of the edit, the freezing and the thawing of the embryo, the embryo's journey from lab to farm in a thermos. Now, Van Eenennaam floats another idea. "No foreplay, the poor guy," she says, a cheeky grin on her face. "The candle and the lighting wasn't right."
UCCE Marin Creates Online 'Story Map' Annual Report

The University of California Cooperative Extension team in Novato has created an online "story map" that capsulizes in an interactive way its ongoing programs and key 2018 accomplishments, instead of a written annual report.
An Inviting Summary of UCCE Marin's Exploits
Why bees swarm and what you should – or shouldn't – do about them
(San Jose Mercury News) Rebecca Jepsen, April 16
…Last year was a particularly bad year for honey bees. Some bee keepers reported up to a 90 percent loss in their hives in 2018. Causes for this include varroa mite infestations, increased pathogens due to the warm weather, increased use of pesticides and a decrease in diversity of food sources.
So, what can we do about a swarm? “If you leave the bees alone, they will leave you alone.,” said Dr. Elina L. Niño, honey bee expert at UC Davis. “It only takes a few hours or at most a day or two for them to find and settle into their new home.”
Santa Maria expects big strawberry crop
(The Packer) Carol Lawrence, April 16
…Two of the three top-yielding varieties in production yield studies conducted in Watsonville by the University of California, Davis, include the monterey variety, producing 10,554 cartons per acre, and the san andreas variety, which yielded 10,414 cartons per acre. O'Donnell said the commission has noticed those varieties as well as some proprietary ones from growers.
“We're seeing more fruit per acre from when these fruits are planted,” she said.
A newer variety, the cabrillo, was reported as producing 11,605 cartons per acre in recent tests.
These California communities could be the next Paradise. Is yours one of them?
(Sacramento Bee) Ryan Sabalow, Phillip Reese and Dale Kasler, April 11
…“There's a lot of Paradises out there,” said Max Moritz, a fire specialist at UC Santa Barbara.
California's state-of-the-art building codes help protect homes from wildfire in the most vulnerable areas, experts say. But the codes only apply to new construction. A bill introduced by Assemblyman Jim Wood would provide cash to help Californians retrofit older homes.
“This will go a long way toward these different municipalities (in showing) that they deserve funding,” Moritz said.
U.C. Davis Animal Science Professor Discusses Agriculture's Contribution to Climate Change
(Cornell Sun) Stacey Blansky, April 11
On Monday afternoon, Prof. Frank Mitloehner, animal science and Air Quality Extension Specialist at the University of California, Davis, discussed the latest research surrounding animal agriculture and its “surprisingly modest” contribution to global greenhouse emissions. Mitloehner pointed at food waste as the largest contributor to environmental damage.
Scientists studying smoke taint as next fire season approaches
(Farm Press) Lee Allen, April 10
…A Los Angeles Times report on the subject put it this way - “Smoke taint rears its head when grapes, kissed by environmental smoke as they're growing, eventually yield a wine with unexpected smoldering flavors…, ‘like drinking from a well-used ashtray,'” using the words of University of California-Davis enology specialist Anita Oberholster. The story noted: “It's a vintner's worst horror movie nightmare - the smoke is coming from inside the grapes.”
Says Oberholster: “Compounds that are responsible for smoke taint are naturally present in grapes at low levels, they add complexity to the wine. Research into the subject is a slow process and to date, I can say there is very little you can do to prevent extracting smoke taint compound from grapes. We are currently in the process of evaluating different amelioration techniques from finished wines and there is some promise there, but research is still on-going, and I have no data yet.”
The farmer that saw his budding California tea farm go up in smoke
(San Francisco Chronicle) Jonathan Kauffman, April 8
…What Mike Fritts didn't know in 2010 — what almost everyone had forgotten, in fact — was that the UC Extension Service planted California's first modern test plot of Camellia sinensis in Fresno in the 1960s, when it partnered with Lipton.
Jacquelyn Gervay Hague, a chemist at UC Davis who conducts studies of tea-growing in Taiwan and is active in the university's Global Tea Initiative, said she learned about the plots just a few years ago when the director of UC Extension's Fresno office gave her a call.
“It blew my mind,” Hague says. She pored over the records, which covered 1963 to the early 1980s, when Lipton pulled out of the study. “It was concluded that we could grow tea very well,” she said.
Goats are the latest weapons in the war against wildfire
(CNN) Sarah Lazarus, April 8
… Lynn Huntsinger, professor of range ecology and management at the University of California, Berkeley, says that California has seen an increase in "fuel" -- the term fire experts use to describe "dead plants."
Huntsinger, who used to keep goats in the backyard of her Bay Area home, says the fire problem has its roots in history.
In the past, Native Americans lit fires to control the vegetation, she says. These deliberate burns created a landscape of open grasslands, so wildfires were smaller and less frequent.
That changed with the arrival of colonial settlers. They did not understand how "using fire prevented fire," and banned deliberate burns from around the turn of the 20th century, says Huntsinger.
The Age of Robot Farmers
(The New Yorker) John Seabrook, April 8
…To get an idea of what might be possible, I arranged to visit Professor David Slaughter in his office at the University of California at Davis. Slaughter leads the university's Smart Farm Initiative, which explores how future farmers might employ emerging technologies. Drones, for example, can automate the inspection of fields for pest or weed outbreaks, and can use high-resolution cameras and algorithmic processing of the images to pick up incipient problems before a farmer or a hired hand might spot them. Another possible application is plant breeding. Breeders currently rely on humans to evaluate seedlings produced by new combinations of already existing varieties.
…If the future of fruit-and-vegetable farming is automation, farmers will not only need the machines, and the funds to afford them, they will also require a new class of skilled farm workers who can debug the harvesters when something goes wrong. Mary Lou de Leon Siantz, a colleague of David Slaughter's at the University of California at Davis, is trying to ensure that domestic farmworkers' children have the STEM skills to compete for those jobs. De Leon Siantz is the daughter of Mexican immigrants; she has a Ph.D. in human development and focusses on migrant health in her research. She hopes to use existing Head Start and 4-H programs to teach math and engineering.
Regional sustainable groundwater management forum hosted in Corning
(Red Bluff Daily News) Julie Zeeb, April 5
Tehama and Butte counties teamed up Friday to host a Northern Sacramento Valley forum on sustainable groundwater held at Rolling Hills Casino.
The event was a collaboration between the Tehama County UC Cooperative Extension and Butte County Department of Water and Resource Conservation.
Allan Fulton, a Tehama County farm advisor, served as moderator.
“We're four years into Sustainable Groundwater Management Act that went into affect Jan. 1, 2015,” Fulton said. “There's been a lot of organizing (of groundwater management agencies). Now the governance structure and planning is underway. This venue is perfect for people to learn about the act and what is going on locally. It's a chance to see, as landowners and water operators, how to engage in the process and give feedback on what they think about it.”
The worst fire in California history illuminates fire preparation needs
(Yuba Net) April 5, 2019
Four months have passed since the Camp Fire, the worst wildfire in California history, ravaged bucolic communities in the Butte County foothills, including Paradise, Concow, Butte Creek Canyon, Cherokee, Yankee Hill and Magalia. Eighty-five people died, many of them elderly and unable to safely evacuate from an area where a wind-driven fire raced from home to home.
The unspeakable loss of human life and the serious challenges being faced by survivors has dominated the Camp Fire conversation. Now, UC Cooperative Extension is beginning a dialog with many agencies involved to understand how such tragedies can be prevented in the future.
UC course helps landowners track water use
(Farm Press) Tim Hearden, April 5
On a recent morning, Jim Edwards and about 70 of his fellow farmers and ranchers from Northern California went back to school. Each was handed a binder full of worksheets as they embarked on a three-hour course to learn how to measure and report their own water diversions – a state requirement now for landowners with rights to draw water from a river or stream.
There were lectures by University of California Cooperative Extension advisors and were even quizzes at the end of each unit so the landowners could demonstrate what they'd learned about open-ditch flow readings, measuring weirs, in-pipe flow meters, the calibration and accuracy of measuring devices, and measuring reservoir diversion quantities.
“I think it's great,” said Edwards, who takes water from Antelope Creek near Red Bluff to raise cattle, orchards and hay.
… “I think this is a good crash course to get people to understand flow measurements and what is required of them to report,” says Khaled Bali, a UCCE irrigation specialist who helps lead a course unit on device accuracy.
DIY with classes at the UC Cooperative Extension in gardening and food preservation
(New Times SLO) Camillia Lanham, April 4
A soft-hued planter full of pale gray-greens and purple flowers waits just through the gate of the Garden of the Seven Sisters off Sierra Way. Those winter colors will soon be replaced by flora made just for spring. This "curbside garden" is the first of 15 demonstration plots manned by Master Gardener Program volunteers at the UC Cooperative Extension in San Luis Obispo.
If you're a newbie like I am—or an oldie looking for some new tricks—the UC Cooperative Extension in San Luis Obispo County has got something just for you. Whether you're trying to figure out what to do with all of that extra produce on your kitchen counter or trying to decide exactly what to plant and when, there's probably a class for that either through the extension's Master Gardener Program or Master Food Preserver Program. You can become certified as a master and volunteer for either program or both programs, or you can dabble with a class here or there.
Backyard chickens hit hard by a long-gone, extremely contagious disease
(New Food Economy) Tove Danovich, April 4
In California, backyard birds are in lockdown. County fairs are canceling their poultry shows. Veterinary hospitals aren't accepting chicken appointments. Local 4-H leaders are telling chicken owners to keep their birds sequestered. Some poultry breeders are even worried their birds will need to be euthanized.
… There are approximately 100,000 backyard flocks in California according to Maurice Pitesky, Cooperative Extension poultry specialist with the University of California, Davis, School of Veterinary Medicine. “They don't focus so much on biosecurity, which is just a fancy word for disease prevention,” he says. Backyard poultry owners regularly mock the CDC's advice to avoid snuggling or kissing their chickens, but that's not the worst of it: 25 percent of urban poultry owners reported not even washing hands after handling their birds.

It Wasn't Just the Soda Tax That Dropped Berkeley Soda Sales by 52 Percent
(The Inverse) Emma Betuel, April 3
University of California, Berkeley professor Sofia Villas-Boas, Ph.D., and Ph.D. candidate Scott Kaplan show in the new paper that soda purchases fell between 10 and 20 percent on Berkeley's campus directly after the soda tax was passed but before the prices officially increased in 2015. They also used Nielsen data to show a similar pattern: soda purchases at local stores decreased by 10.8 percent even before the higher prices went into effect.
“The election outcome caused a 10-20% reduction in sales of regular soda beverages before consumers faced higher prices anywhere, on campus or in stores off-campus,” Kaplan tells Inverse, “This suggests that you might not witness these types of effects if a sugar-sweetened beverage (or soda) tax was implemented without a preceding campaign and public vote.”

Tiny whiteflies seem to be bugging people across the Central Coast, but why are there so many this year?
(KSBY) Megan Healy, April 1
A master gardener from the SLO University of California Cooperative Extension says dozens of people from south SLO County called asking why there are so many.
“It's probably a reflection of the increasing temperatures coming on top of all that nice water we have had, so we have had a flush of vegetation and the flies that came from eggs originally have just all hopped out,” said Cathryn Howarth, a master gardener a the SLO County UC Cooperative Extension.
According to the UC Agricultural and Natural Resources Statewide Integrated Pest Management Program, signs of whitefly manifestation include…
Inside the race to build the burger of the future
(Politico) Michael Grunwald, April 1
…Conglomerates like Walmart, McDonald's and General Mills have been setting emissions reduction targets for their suppliers, which will ratchet up pressure on farmers and ranchers to green their operations. But at a time when they're already getting squeezed by a handful of giant agribusinesses that process their animals, as well as the economic fallout from President Donald Trump's trade wars, they're hoping for government incentives to reduce their emissions. Frank Mitloehner, a professor of animal agriculture at the University of California-Davis, believes farmers and ranchers deserve to be paid for their ecological services—and recently said so to an Ocasio-Cortez staffer. For example, California is spending hundreds of millions of dollars to help them manage their manure in cleaner ways, which makes more sense to Mitloehner than demonizing them for the messes they make while putting food on people's tables. Many of them are conservative Republicans who deny climate science, but they're also pragmatic businesspeople—Mitloehner says they could store tremendous amounts of carbon on their lands if the price and the politics were right.
“Politically, farmers tend toward the Trump camp, and when they hear all this finger-pointing about farting cows, they just shut down,” Mitloehner says. “It troubles me, because I know how urgent this climate discussion is.”
… “There's such an enormous opportunity to reduce emissions in meat production, if you didn't hear all this counterproductive talk about how everything about it is terrible,” says Mitloehner, the Cal-Davis agricultural scientist. “Let's not alienate the people we need the most on our quest for a climate solution.”
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
(Ag Alert) Kathy Coatney, Aug. 15
"It's generally too difficult to get trucks out on such a short notice," said Glenn Nader, University of California Cooperative Extension livestock and natural resources advisor emeritus for Butte, Sutter and Yuba counties.
… Carissa Koopmann Rivers, UCCE livestock and natural resources advisor for Siskiyou County, said the Klamathon fire, first reported in early July, devastated the town of Hornbrook, which is situated in a cattle-producing area.

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

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

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

Trump wants to clear more trees to halt fires. The feds need to spend more, experts say.
(Sac Bee) Emily Cadei and Kate Irby, Aug. 7
“I think for a number of years the feds were more ahead of this dilemma, at least in discussions,” said Scott Stephens, a professor of fire science at the University of California, Berkeley. But “I have to say right now, I think the state is moving ahead. It's certainly being more innovative, it's doing more policy work.”
Trump says California's water policies are making the wildfires worse. Is he right?

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 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.

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.
Sorkin said she asked Modern Farmer's online audience to nominate standout agents in their regions. The seven profiles, she wrote, "salute the people who just might be the most important, least celebrated civil servants in the United States."
In the article, Cooper shared a defining early career experience in which she found a destructive Mediterranean caterpillar in a local vineyard that had never been seen in the U.S. Detection of European grapevine moth triggered a team of state, federal and UC scientists to develop an action plan to limit the pest's distribution in California.
“I had to learn, quickly, to balance the scientific research with the needs of local growers and the massive media attention.” Cooper said.
Cooper works with farmers who are producing California's storied Napa Valley wines. In all, her region comprises 600 grape growers and 48,000 acres of vineyards, the article said. The reporter talked to the director of operations at Huneeus Vineyards, Mayacamas Olds.
“Monica helps me work through all sorts of stuff, like controlling leaf-roll infections,” Olds says. “She always brings the right people to the table," the vineyard director of operations said.
Cooper was the only California advisor profiled in Modern Farmer. The other extension professionals hailed as 'unsung heros' were from Vermont, Arkansas, North Carolina, Colorado, Texas and Maine.
Pierce's disease is caused by Xylella fastidiosa bacteria, which can be spread by a variety of sharpshooter insects. The outbreak in Napa and Sonoma counties is associated with blue-green sharpshooters.
There's been a “huge increase in traditional (Pierce's disease) hotspots and in sites not normally affected,” said Rhonda Smith, UC ANR Cooperative Extension viticulture advisor in Sonoma County. Smith said the worst problems seem to be in areas with the warmest winters. The Russian River Valley and Dry Creek areas have been the hardest hit.
In Napa County, a similar patchwork of vineyards were impacted by Pierce's disease last year, said Monica Cooper, the UC ANR CE viticulture advisor in Napa County. She said there has been a "marked increase" in areas where the disease is normally seen. In areas along riverbanks where habitat restoration has taken place, the problem is diminished. In the past, non-native plants along riverbanks have acted as reservoirs for X. fastidiosa, keeping the bacteria in the area even after infected vines have been destroyed.
UC ANR CE advisor at the Central Coast, Larry Bettiga, said the area hasn't seen a corresponding increase in Pierce's disease.
"The more lush river system in Napa and Sonoma counties has plenty of areas to serve as reservoirs for both the bacteria that causes Pierce's and its vectors," Bettiga said. “We don't have blue-green sharpshooters in Monterey County.

The lengthy article was written in honor of UC Cooperative Extension's 100th anniversary. The organization was formed on May 8, 1914, when President Woodrow Wilson signed the Smith-Lever Act into law.
For the story, Franson interviewed Barbara Allen-Diaz, vice president of UC Agriculture and Natural Resources, and several UCCE advisors who work in Northern California viticulture. Allen-Diaz noted agriculture's wide scope in the Golden State.
“We farm 400 commodities in California with a value of $45 billion,” Allen-Diaz said. UC Ag and Natural Resources focuses on healthy food systems, healthy environments, healthy communities and healthy Californians.
Rhonda Smith, a UCCE advisor in Sonoma County, said she has seen many changes since she started in 1986.
"In early days, most growers were small, independent farmers," Now most of the people Smith works with are employees of large corporations, many multinational.
In the early days, farm advisors dealt with multiple crops, and the viticultural work and research was primarily focused on improving the culture of vines. Things soon changed. “Increasingly, the trials were associated with grapevine pests, especially exotic pests,” Smith said.
Monica Cooper, UCCE viticulture advisor since April 2009, walked into a big problem when she took her job: the European grapevine moth. She also conducts research with mealybugs and leafroll virus and believes red botch virus and water issues to be important concerns for winegrape growers in the near future.
Glenn McGourty, UCCE advisor in Mendocino County, agrees.
“I’ve been telling growers that they need to learn to farm without irrigation,” McGourty said.
