Hoddle, Choe, Haviland receive $1.34 million for chlorpyrifos alternatives

From left, Mark Hoddle, Dong-Hwan Choe and David Haviland received CDFA grants for research on pest control alternatives to the banned pesticide chlorpyrifos.

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.

 

New DPR grants enable research into alternatives to the banned pesticide for citrus, grapes and other crops.

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.

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

Dong-Hwan Choe
UC ANR scientists Dong-Hwan Choe, Surendra Dara, David Haviland and Jhalendra Rijal received awards for their exemplary work from the Pacific Branch of the Entomological Society of America. The PBESA presented its annual awards on April 20, at a virtual ceremony due to the coronavirus pandemic.

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.

Surendra Dara
Choe also participates in workshops for agricultural pest control advisers, UC Master Gardeners and urban pest control operators.

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.

The Pacific Branch covers provinces/states in Canada, U.S. and Mexico on the Pacific Coast.

ANR develops innovation incubation strategy

Fred Mendez (center), of Union Bank, was among the 40 people who met on Aug. 30 to develop a comprehensive strategy to nurture new technologies and innovative businesses for agriculture and natural resources.

“If UC ANR isn't an incubator, I don't know what is. Furthermore, I would argue that the partnership of our land-grant university system with Cooperative Extension is the original and most productive incubator that the world has ever seen,” VP Glenda Humiston wrote in the October-December 2015 issue of California Agriculture.  

Since joining ANR, Humiston has been working to expand UC ANR's incubation activities by joining with diverse partners to develop a much broader innovation infrastructure specifically designed to support intellectual property, innovation, entrepreneurship, tech transfer, startups and commercialization aimed at agriculture, natural resources and rural communities. 

“A lot of people have ideas, but they don't know how to be business leaders. An incubator connects them with the things they need to be successful as new entrepreneurs,” said Gabe Youtsey, chief information officer.

"We're catalyzing like-minded partners to jointly develop the needed statewide innovation infrastructure,” Humiston said.

To kick off development of such a system, Humiston brought together 40 people on Aug. 30 with a wide range of expertise and representing a variety of sectors: agriculture, banking, business, government, technology and higher education – including leaders of several successful incubators. The purpose of the meeting, held at the ANR building in Davis, was to engage the group in developing a comprehensive strategy to nurture new technologies and innovative businesses for agriculture and natural resources. 

“We're not looking to reinvent the wheel or duplicate existing efforts,” Humiston said, explaining that she hopes to support and leverage the strengths and efforts of partners.

Christine Gulbranson, UC senior vice president of research innovation and entrepreneurship, and Reg Kelly of UC San Francisco, who created QB3, – one of UC's best performing incubators – participated in the session. The quantitative biologists at UC Berkeley, UC San Francisco and UC Santa Cruz who comprise QB3 take on challenges in biology using physics, chemistry, and computer science. QB3's Startup in a Box provides legal and grant-writing help for biotech startups.

“We want to take the QB3 model and modify it for ANR,” Humiston said. “But we don't have the resources to build a statewide system by ourselves so we're catalyzing like-minded partners to jointly develop the needed statewide innovation infrastructure.”

Such an innovation system could benefit a wide array of entrepreneurs in rural areas and help to commercialize ideas generated by UC Cooperative Extension specialists and advisors.

“Over the past eight years, ANR researchers have filed 148 patents,” Humiston said. “However, it is unclear if many of those had the support they needed to go the next step.”

Participants identified resources available and gaps around innovation, place, talent, stewardship and engagement.

At the meeting, the group divided into five tables of eight people. Each table had representatives of UC ANR, various UC campuses, state and federal government, funding institutions, incubators, and different industries. They discussed issues around innovation, place, talent, stewardship and engagement, answering the following questions:

  • What exists now?
  • Where are the gaps that need to be filled?
  • Which of these gaps could UC ANR help catalyze and fill, either with partners or on its own?
  • How could this work to fill the gaps be funded?
  • How do we measure success?

Conversations were lively and many ideas were brought forth for specific projects and other implementation. “It's really exciting,” said Humiston. “People were jazzed. Virtually all of the participants said they want to work with us on next steps.”

In addition to Humiston and Youtsey, AVP Wendy Powers and UCCE advisors David Doll and Andre Biscaro participated for ANR. Consultant Meg Arnold is writing up a report, which is expected to be released in early October.
