UC IPM’s Farrar briefs legislators on threats to California winegrapes

Jim Farrar, left, updated legislators on pests and diseases that pose a threat to California wine grapes.

Recent surveys in the North Coast have found that 90 percent of the powdery mildew samples collected were resistant to strobulurin fungicides, the director of UC Integrated Pest Management Program told legislators at a joint hearing of the California Assembly and Senate Select Committees on California's Wine Industry. A potential solution is breeding winegrapes to be resistant to powdery mildew, but a drawback is that the wine industry is largely known for its varietals.

“Professor Andy Walker at UC Davis has succeeded in crossing winegrapes with a wild grape species that is naturally resistant to powdery mildew and then crossing the offspring back to the parent winegrape variety for several generations,” said James Farrar, who was invited to speak at the committees' informational hearing on “Fire Recovery and Pest Management Awareness” at UC Santa Barbara on Nov. 7.

In addition to powdery mildew, he also talked about red blotch virus, which was relatively recently identified in California, and grapevine leafroll associated virus and the mealybug species that transmit the virus. Bob Wynn from the California Department of Food and Agriculture gave an update on Pierce's disease and its vector glassy-winged sharpshooter.

Farrar warned the legislators of increased human health risks due to “unintended consequences of social pressure” on the herbicide glyphosate, which growers use to control weeds under grapevines rather than tilling the soil, to comply with Natural Resources Conservation Service and Salmon Safe guidelines.

“Recent social pressure resulting from the International Agency for Research on Cancer labeling glyphosate a probable human carcinogen and news stories indicating detection of glyphosate in wine have caused some growers to look at other herbicides,” Farrar said. “The other choices are glufosinate, which is more risky to applicators, less effective, and more expensive, and paraquat, which has similar price and effectiveness, but much greater risk to applicators. Paraquat is a restricted-use pesticide that is highly toxic to humans – 3 teaspoons will kill an adult. It has a higher risk ‘Danger' label in contrast to the lower risk ‘Caution' label for glyphosate.

“This is an increased risk to human health as a result of misplaced public perception of risk.”

Farrar closed his comments by saying, “The County Agricultural Commissioners and county-based University of California Cooperative Extension advisors are vital in the continued efforts to manage winegrape pests and diseases. They are the frontline support for growers and pest control advisers in this effort.”

More Latinos are joining 4-H, according to initial UC ANR outreach report

Latino youth participation in 4-H is on the rise, according to a report on the first year of UC Agriculture and Natural Resources' three-year 4-H Latino Initiative.

Increasing Latino participation in 4-H has been a priority for some time. Over the last five years, participation in 4-H increased 41 percent; Latino participation increased 173 percent. While growing, the fraction of 4-H members who are Latino still falls below their proportion of the state's population.

“We're just getting started in implementing a new statewide comprehensive plan to reach Latino youth,” said Lupita Fabregas, assistant director for 4-H diversity and expansion. “We know 4-H helps prepare kids for success in college and life. We're thrilled to be involving more Latinos.”

When 4-H was formed 100 years ago, it was an educational club for farm kids. Often seen in spotless white and kelly green garments, participants raised animals, gardened, cooked and sewed while learning leadership and public speaking skills. In the latter half of the 20th century, when California became more urbanized, 4-H began adding education in broader program areas, such as rocketry, robotics, computer science and environmental stewardship.

California demographics were also changing. The state became more ethnically diverse. In 2014, Latinos surpassed whites as the largest ethnic group. But they weren't reaping the benefits of 4-H membership at the same rate.

UC Agriculture and Natural Resources (UC ANR) the 4-H parent organization in California, researched the reasons for low Latino 4-H membership, and realized there were opportunities to develop new program models and methods to reach minority populations without changing the 4-H core values.

“As an organization, we identified the values and core elements of 4-H that make us unique,” said Shannon Horrillo, UC ANR statewide 4-H director. “We decided that no matter how we adapted the program, we would not stray from those foundational elements.”

Core elements include youth leadership, youth-adult partnerships, life skills learning, community service and service learning, the 4-H Pledge, and well-known 4-H name and green four-leaf clover emblem. It became apparent that some of the requirements that were part of the community club tradition – such as the required meeting attendances, parliamentary procedures and officer structure – were barriers to extending the program to a more diverse population.

“We can be more flexible in how the program looks and in requirements while maintaining what has made 4-H an impactful program for more than 100 years,” Horrillo said.

New club models were launched, including special interest clubs (called SPIN clubs), in-school clubs and after-school clubs.

4-H members learn about agricultural science.

4-H membership began looking a lot more like the highly diverse citizenry in the state's densely populated cities. In 2016, UC ANR allocated funds to employ bilingual 4-H community education specialists in seven California counties for three years to further boost Latino participation. The specialists are making a concerted effort to reach out to Latino youth, parents, community leaders, schools, churches and other organizations to extend 4-H programming to wider and more diverse audiences in Kern, Merced, Monterey, Orange, Riverside, Santa Barbara and Sonoma counties.

“Our staff are making strides in adapting 4-H to be culturally relevant for Latino youth,” Fabregas said. “This work will help all youth feel welcome, appreciated and valued in 4-H programs.”

The new effort will include a fundraising program to maintain and expand the emphasis on Latino outreach after the current three-year funding period concludes. The UC ANR Development office is working with the 4-H Latino Initiative to develop a plan to combine local fundraising, grant awards, contracts with schools and agencies, and foundation and private gifts to keep the program going beyond the current three-year term.

“Though the progress to date has been significant, we know that we'll need to hire more community educators to strengthen our resources if we're going to bring 4-H to a great number of Latinos,” said Andrea Ambrose, UC ANR director of development.

Preparing to evacuate during wildfire? These checklists can help

As more than 20 major wildfires burn in Northern California, residents in those regions need to be ready to evacuate on short notice. The wind-driven fires are moving quickly and can change direction unexpectedly.
 
“It is pretty tense here as the fire north of us keeps circling back and forth,” said Glenn McGourty, UC Cooperative Extension director in Mendocino County, on Oct. 12. “So far most of the damage has been in Redwood Valley, where over 200 homes were lost and people had only minutes to get out.”

To help people prepare, CAL FIRE has a checklist for evacuation online at http://www.readyforwildfire.org/Evacuation-Steps. UC Agriculture and Natural Resources scientists contributed to the research behind the recommendations.

A one-page checklist online at http://disastersafety.org/wp-content/uploads/2016/07/IBHS-Wildfire-Last-Minute-Checklist.pdf, also based on research by UC ANR scientists, is available from the Insurance Institute for Business & Home Safety.

Napa County residents have been told to be prepared in case they need to leave.

“We have team members tending to their own homes and or family's needs, providing support in shelters, and being available for immediate clientele needs in any way they can,” said David Lewis, UC Cooperative Extension director in Napa and Marin counties. “We look forward to calling upon UC colleagues with more experience to support our communities in the long recovery period. For the immediate future, we will stay focused in our efforts to support evacuation and shelter efforts – personal safety and needs are priority one until the fires no longer pose a threat.”

The main thing to remember when preparing to evacuate is to protect your life first.

“Don't die trying to prepare your house before you leave,” said Yana Valachovic, UC Cooperative Extension director and forest advisor in Humboldt and Del Norte counties. “Monitor the situation, watch the wind directions, and listen to all emergency personnel.”

To receive timely updates on fire conditions, Brian Oatman, UC ANR Risk & Safety Services director, uses Nixle. “While some communication methods may not work due to outages, the more sources we have, the better the chance that the message gets through,” Oatman said. To sign up for text alerts, visit http://www.nixle.com or text your zipcode to 888-777 to opt-in.

“We have coordinated with CropMobster to create a resource list at https://sfbay.cropmobster.com/bay-area-fire-resources where anyone can post any needs or offer help of any kind,” said Stephanie Larson, UC Cooperative Extension director in Sonoma County. “UCCE Sonoma has also created a Disaster Recovery for Agriculture Operations at http://cesonoma.ucanr.edu/Disaster_Resources for homeowners and managers of rangelands. UCCE is working closely with Sonoma County to provide UC ANR resources to assist with the recovery of our community that has been devastated by this fire.”

In Yuba County, the Cascade fire is 45 percent contained as of Oct. 12. “Evacuation orders are being lifted in parts of Yuba County,” said Janine Hasey, UC Cooperative Extension director for Sutter and Yuba counties. “Kate Wilkin, our new UC Cooperative Extension forestry, fire science and natural resources advisor in Sutter, Yuba, Butte and Nevada counties, has assembled resources for residents who are returning to their homes at http://cesutter.ucanr.edu/Fire_Information. We will be updating the website with more recovery information in the coming days.”
