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.

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.

AI can help growers more precisely manage their fields, Humiston tells Little Hoover Commission

Glenda Humiston gave testimony on the impacts of artificial intelligence in the agricultural sector to the Little Hoover Commission in Sacramento on Jan. 25.

Artificial intelligence, or AI, can improve precision agriculture by using sensed environmental data to “learn” and continually adapt, VP Glenda Humiston told the Little Hoover Commission at a hearing in Sacramento on Jan. 25.

The Little Hoover Commission is reviewing the impacts of artificial intelligence. While there is no singular definition, artificial intelligence encompasses a broad range of technologies that seek to approximate some aspect of human intelligence or behavior.  

Throughout its study, the commission will consider the potential policy role of California state government in areas such as regulation, workforce development and retraining.

Humiston was asked to give a statement on the impacts of artificial intelligence in the agricultural sector.

“California's working landscapes face some critical challenges; among those are drought, climate change, air quality, soil health, pests, pathogens and invasive species,” she said. “Additionally, rural/urban conflicts and urban sprawl continue to reduce available farm land and make viability of food production more difficult.

“Of importance to today's hearing, California's labor-intensive crops are facing increasing difficulty accessing necessary labor – both skilled and unskilled. This situation has led growers and universities to seek solutions through mechanization, automation and other new technologies.”

She sees opportunities in precision agriculture for growers and ranchers to more precisely manage their operations by using site- and crop-specific data gathered by new technologies.

“Artificial intelligence improves this further by using the sensed environmental data to ‘learn' and continually adapt to ever-changing conditions as it receives data that strengthens the computer's ‘intelligence,'” she said.

Humiston also outlined some of the challenges to harnessing the power of AI for agriculture.

“Artificial intelligence is extremely difficult in agriculture because of the huge amount of variability in environmental conditions across a single field,” she said. “This requires many sensors, complex algorithms, and large real-time data processing – all integrated and working together to inform decisions and actions.”

In a 2014 Pew Research Center survey, the vast majority of the 1,896 experts anticipated that robotics and artificial intelligence will “permeate wide segments of daily life by 2025.” The commission's artificial intelligence project will investigate the shape and speed of these changes in California and in society.

Through its public process, the commission intends to study the key challenges of artificial intelligence in California, its economic implications and how it can be used to solve societal ills. The commission will review issues such as justice, equity, safety and privacy. The project will consider recent studies on workforce impacts, which could include both job creation and job displacement. Possible mitigations and worker protections will be discussed as will examples of efforts to plan and prepare for innovations and labor transformations.

Pramod Pandey
Pandey receives state's highest environmental honor 

California Safe Soil and Pramod Pandey, UCCE specialist in UC Davis School of Veterinary Medicine, were among 13 California organizations that received the state's highest environmental honor, the Governor's Environmental and Economic Leadership Award (GEELA), in a ceremony at the California Environmental Protection Agency in Sacramento on Jan. 17.

The award recognizes the public-private partnership and collaborative research among California Safe Soil, the UC Davis School of Veterinary Medicine and the California Department of Food and Agriculture to recycle organic food waste into fertilizer and feed for agricultural use.

California Safe Soil has a proprietary new technology – enzymatic digestion – to recycle organic biomass. However, they had to prove that recycling food into fertilizer and feed can be done safely, without foodborne pathogens.

California Safe Soil worked with Pandey to conduct pathogen challenge research. Annette Jones and Douglas Hepper at CDFA and Bart Weimer, professor in the School of Veterinary Medicine, and Glenn Young, professor in the Department of Food Science and Technology, helped formulate the pathogen challenge test, which provided the scientific results needed to allow CDFA to issue an operating license for the enzymatic digestion.

Pandey's research, which was published in a peer-reviewed journal, proved that California Safe Soil's method for recycling organic food waste into fertilizer and feed is based on robust science and technology.

GEELA recipients are chosen from five categories including climate change, ecosystem and land-use stewardship, environmental education, sustainable practices and waste reduction.
