The California Department of Pesticide Regulation has awarded $1.34 million in grants to UC ANR scientists for research on pest control alternatives to the banned pesticide chlorpyrifos.
"Finding less-toxic alternatives to pesticides like chlorpyrifos, and promoting their adoption and implementation throughout California, is a priority, and our grant programs play a vital role in reaching those goals," DPR Director Val Dolcini said.
The grants, awarded through DPR's Research Grants Program, will go to the following researchers:
- Mark Hoddle, UC Cooperative Extension entomology specialist, UC Riverside, "Taking Chlorpyrifos out of Citrus: Maximizing IPM of Argentine Ant and Sap Sucking Pests with Biodegradable Hydrogels, Infra-Red Sensors and Cover Crops." ($500,000)
- Dong-Hwan Choe, UC Cooperative Extension urban entomology specialist, UC Riverside, "A sustainable boric acid liquid bait delivery system (as alternative to chlorpyrifos sprays) for the management of pest ants in agricultural settings." ($340,467)
- David Haviland, UC Cooperative Extension IPM advisor for Kern County, "Hydrogel baiting systems for sugar-feeding ants in California grapes and citrus." ($500,000)
"These researchers are at the cutting edge of their fields and I'm really pleased that DPR can support their efforts," said Dolcini.
Full descriptions of each research project are available on DPR's website.
Funding for these grants came from a one-time $2.1 million General Fund allocation to DPR for research projects that advance safer, more-sustainable pest management alternatives to chlorpyrifos. DPR previously funded three research grants for alternatives to chlorpyrifos research.
Following California's historic decision to end use of the pesticide chlorpyrifos in 2019, DPR and the California Department of Food and Agriculture (CDFA) convened the Alternatives to Chlorpyrifos Work Group to evaluate potential alternatives. The work group's report outlines actions that can further support agriculture and the health of local communities, farmworkers and the environment.
Soule named assistant vice provost for CE
Katherine Soule will serve as ANR's new Assistant Vice Provost for Cooperative Extension. She will start her new duties on July 1, 2020, and continue to serve as UCCE director for San Luis Obispo and Santa Barbara counties and as UCCE youth, families and communities advisor. The role was previously held by Lynn Schmitt-McQuitty until she assumed the role of Statewide 4-H Youth Development Program director.
“We are excited to have Katherine on the Cooperative Extension administrative team! She brings a breadth of Cooperative Extension experiences and leadership skills,” said Mark Lagrimini, vice provost for research and extension. “Katherine is known for her innovative, collaborative, and strengths-based leadership. She cares deeply about improving lives and working environments for her unit, her community and ANR.”
Soule earned her Ph.D. from the University of Georgia, Athens in 2013 and became the UCCE youth, families and communities advisor for San Luis Obispo and Santa Barbara counties. In 2017, she accepted an additional appointment as UCCE director for these counties. She was elected as UC ANR's Academic Assembly Council president for a two-year term ending in June 2020.
"As the assistant vice provost of Cooperative Extension, I look forward to supporting the development and successes of new and existing county directors,” Soule said. “I hope to promote collaborative, cross-county communication, while focusing on identifying and meeting the needs of county directors across the division. We are all most effective when we learn from and support one another, so I look forward to connecting with academics, county directors, ANR leadership and other UC ANR personnel in this new role."
Choe, Dara and IPM team honored by Pacific Branch of ESA
Choe, UCCE specialist in the UC Riverside Department of Entomology, won the Medical, Urban, and Veterinary Entomology Award.
“Since joining the faculty at UC Riverside in 2011, [Choe] has developed an outstanding research and extension program dealing with the major urban structural pests and related issues in the western United States,” wrote Mike Rust, UC Riverside entomology professor, in his nomination letter.
His research includes exploiting the role of semiochemicals and behavior to control social insects and developing novel ant baits.
“Dr. Choe has been at the forefront of developing hydrogels as carriers of baits to control ants and yellowjackets. Developing cost-effective and environmentally safe delivery strategies has always been a major problem facing the use of ant baits in agriculture and urban setting. His pioneering biodegradable alginate beads promise to be a major advancement,” Rust wrote.
Dara, UC Cooperative Extension entomology and biologicals advisor for San Luis Obispo and Ventura counties, won the Award for Excellence in Integrated Pest Management.
This annual award recognizes individuals who made outstanding contributions in research and outreach in the area of IPM. Dara's new IPM model has been well-received and its impact has been documented in a UC Delivers story. Dara is the first UC ANR scientist to receive this award and fourth from UC since the Pacific Branch began offering awards in this category in 2009.
The UC IPM Almond Pest Management Alliance Team won the Entomology Team Work Award. The team consists of UC IPM advisors David Haviland and Jhalendra Rijal, former UCCE advisor Emily Symmes, UCCE Kern County staff research associate Stephanie Rill, industry researcher Bradly Higbee of Trécé, USDA scientist Charles Burkes and Bob Curtis of the Almond Board of California.
The team encouraged the adoption of mating disruption for managing navel orangeworm, a major pest in almond orchards, especially in the San Joaquin Valley. After they began demonstrating that mating disruption proved to be an economical pest control method in orchards, they saw a rapid rise in growers adopting the technology. Based on a survey of pest control advisers and growers conducted in the early 2019, the anticipated use of navel orangeworm mating disruption for the 2019 season in San Joaquin Valley was 32%, as opposed to the 7% adoption in 2017. Kern County data showed a 26% countywide increase in the adoption of mating disruption from 2017-2018.
For more than a decade, the team conducted research on navel orangeworm, spider mites, leaffooted bug and ants that laid the groundwork for IPM adoption. For the past three years, the team put these IPM practices on display using nine demonstration orchards across the San Joaquin Valley as part of CDPR Pest Management Alliance and Almond Board of California grants.
The UC IPM Almond Pest Management Alliance Team received an award in February from the California Department of Pesticide Regulation and California Environmental Protection Agency
Three UC Davis faculty members were also selected for prestigious awards: Lynn Kimsey, Walter Leal and Robert Kimsey.

There are 19 wildfires threatening communities all over the state and causing concern for our friends and colleagues. We've been in touch with our colleagues in the fire zones and everyone is safe and, as far as we know, no ANR members have lost homes. Here's an update from the affected areas.
In Lake County, the UCCE office is closed and staff members have been evacuated from their homes since Saturday due to the Mendocino Complex fires.
Hopland REC was hit hard by the River Fire. The good news is the evacuation order was lifted Monday and all Hopland Research and Extension Center employees are safe and the headquarter buildings are undamaged. The guard dog that had gone missing has been found. The animals were moved on Friday and all livestock are safe and accounted for. Roughly 2500 acres of the upper pastures burned and the domestic water line from the spring is down. On Friday, Cal Fire set up Incident Command Post at Hopland REC with 6+ engines, three bulldozers and a water tanker. Kudos to John Bailey, superintendent and interim director, and staff for their efforts, which no doubt limited the damage.
UCCE Shasta office is open. Many staff members evacuated due to the massive Carr Fire. Last week, 4-H members helped relocate animals to safety. At least one 4-H family lost their home to the Carr Fire – and 4-H advisor Nate Caeton fears others he hasn't been able to contact in the West Side 4-H Club have lost homes – so the local UCCE staff is reaching out to see how they can help.
UCCE Mendocino office is open. All employees are safe and the office suffered no damage from the Ranch Fire.
UCCE Riverside office is open. A Master Gardener volunteer lost her home in Idyllwild to the Cranston Fire. UCCE Master Gardener coordinator Rosa Olaiz and the rest of the UCCE Riverside County staff are safe and are making plans to assist the volunteer.
UCCE San Bernardino office is open and all staff members are safe from the Cranston Fire.
As the fires are still active, we're continuing to monitor the situation and hope for the best.
Because emergencies can arise without warning, UC ANR Environmental Health and Safety has this Safety Note to help make plans http://safety.ucanr.edu/files/152253.pdf. You can also learn what to do before, during and after a fire at http://cesutter.ucanr.edu/LivingWithFire, a website by Kate Wilkin, UCCE forestry, fire and natural resources advisor for Sutter, Yuba, Butte and Nevada counties.
Thank you all for your hard work and dedication, especially those of you impacted by the fires.
Intermountain Research and Extension Center (IREC) celebrated the grand opening of a multipurpose conference and laboratory building on July 26. The facility will be available for use by private and public groups for business meetings, job fairs, trainings and conferences.
"The facility is the first in the Tulelake area to offer modern audio-visual infrastructure and high-speed internet connectivity capable of supporting remote presentations to stay in touch with groups from around the world," said Rob Wilson, IREC director. "We hope this facility will greatly increase the visibility and accessibility of local events and help draw more regional attention to the area."
The conference room was dedicated in honor of the late John Staunton, a local research collaborator with UC Agriculture and Natural Resources who passed away in 2015. Staunton Farms and the Staunton family donated $25,000 to support the building project and recognize the Tulelake farmer and his long-standing support of agriculture and research.
Winema Elevators/Western Milling, Sensient Natural Ingredients, Macy's Flying Service, and Basin Fertilizer also contributed support.
UC awarded approximately $2 million for this capital improvement project with funds from UC lease revenue bonds to pay for most of the building's design and construction costs, but additional support is needed to complete the project. Intermountain REC has set a fundraising goal of $100,000 to pay for tables, chairs, furnishing and lab equipment for the building.
A special UC fund has been created to collect tax-deductible contributions to be used solely for this building project. Donations over $50 will receive recognition in print and on the IREC website. Donations over $1,000 will receive recognition on the donor wall in the building entryway. Name plate recognition on the donor wall will be based on the gift amount: Gold ($2,500+), Silver ($1,750 to $2,499), and Bronze ($1,000 to $1,749). Donations can be made via check using the enclosed envelope or by credit card by visiting the IREC website at http://irec.ucanr.edu and clicking the “Make a gift” link.
The ribbon cutting followed the 2018 IREC field day, an annual event that showcases the research underway at the 140-acre facility. Charlie Pickett of USDA, UC Davis Plant Breeding Center director Charlie Brummer, UCCE farm advisors David Lile and Rachael Long and UCCE specialist Dan Putnam joined Wilson in giving research updates on the tour.
Research presentations included work on biological control of cereal leaf beetle, influence of fall harvest management of irrigated grass hays, onion white rot, managing alfalfa weevil and clover rootcucurlio, pulse crop options for theKlamath Basin, cover crops and amendments, cutting schedule effects on lowlignin alfalfa andgermplasm evaluation of alfalfa and tallfescue.
Siskiyou Daily News, noted the palpable absence of the late Steve Orloff, who was a UCCE farm advisor for Siskiyou County for 25 years. “Orloff's absence was noticeably felt throughout the day,” she wrote. “He passed away in October of 2017, and his influence in Siskiyou County's ag industry was very apparent, evidenced in part by the many mentions of his name and work throughout the day. IREC paid tribute to Orloff in the final page of its field day guide, which featured a full-page image of Orloff during a previous field day, with the words, ‘We miss you, Steve.'”
In the news article, Jester also wrote, “The information gleaned through research at the IREC can be invaluable to farmers and other researchers. Through its years of experimentation, the center has helped growers develop more effective practices in a wide range of areas, from determining the crops that will grow best in the local climate, to selecting the most economically viable crops for the region, to understanding the most effective ways to manage pests and disease.”

CASI Center wins WEDA Award of Excellence
The Conservation Agriculture Systems Innovation (CASI) Center received this year's Award of Excellence from the Western Extension Directors Association (WEDA). Dan Munk, UCCE farm advisor in Fresno County and CASI member, delivered a presentation on CASI's goals and accomplishments on July 10 at the WEDA annual conference in Guam, then accepted the award on behalf of the group.
The WEDA Award of Excellence is presented annually to recognize Extension outreach education programming that has achieved outstanding accomplishments, results and impacts in addressing contemporary issues in one or more of the 13 Western states and Pacific Island U.S. Territories.
Composed of scientists and growers, the CASI Center develops and delivers information on the economic and environmental benefits of conservation agriculture systems and strives to increase adoption of locally appropriate systems in California. CASI was founded by and continues to be fueled by Jeff Mitchell, UCCE specialist.
Surveys conducted by the CASI Center indicate that no-tillage and strip-tillage practices were used on less than 0.5 percent of California's annual crop acreage in 2004 (http://casi.ucanr.edu/?blogstart=51& blogasset=14128), but today, an estimated 45 percent of dairy silage acreage in California now uses these production techniques. Major transformations toward reduced disturbance tillage systems have occurred in several other crops including tomatoes, sorghum and cotton.
The application for consideration for the WEDA recognition was submitted by Brenna Aegerter, Howard Ferris, UC Davis professor Amelie Gaudin, UC Merced professor Teamrat Ghezzehei, Kurt Hembree, William Horwath, Louise Jackson, Betsy Karle, Sarah Light, Mark Lundy, Dan Marcum, Milt McGiffen, Glenn McGourty, Michelle Leinfelder-Miles, Mitchell, Gene Miyao, Munk, Tapan Pathak, Samuel Sandoval-Solis, Gary Sposito, Scott Stoddard, Tom Turini, Amber Vinchesi, Jeannette Warnert and Daniele Zaccaria.
In their application, they wrote: “In concert with these reductions in tillage intensity and soil disturbance, estimates of PM10 or fugitive dust by the SJV Air Pollution Control District indicate about 9.2 tons per day lower emissions that are likely due to reductions in tillage intensity and soil disturbance in the eight-county San Joaquin Valley region that was out of compliance with US EPA air quality standards in the early 2000s. This effort was one of several agricultural management approaches that helped the San Joaquin Valley Air Basin achieve and maintain attainment of the PM10 air quality standard. Further evidence of our impacts includes our leadership and founding role in the creation of the California Farm Demonstration Network, as well as our organizing of a very dynamic group of organic farmers in California that is now working together on no-till organic food production systems. Our impact also extends to what we term ‘saturation visibility' of our work through an average of 65 public presentations annually and over 50,000 views of our CASI videos. CASI is now widely recognized as the ‘go to' organization in California for science- and experience-based information and leadership on conservation agriculture principles, practices and systems.”
WEDA represents Alaska, American Samoa, Arizona, California, Colorado, Guam, Hawaii, Idaho, Micronesia, Montana, Nevada, New Mexico, Northern Mariana Islands, Oregon, Utah, Washington and Wyoming.
