UC IPM Makes It Happen

The Walnut Marketing Board (WMB—www.walnuts.org/), representing more than 5,500 California growers, is one of 16 members of the Pesticide Environmental Stewardship Program to be recognized for their efforts to prevent pollution and reduce pesticide risk.

The WMB formed the Walnut Pest Management Alliance (PMA) in 1999 under the leadership of Carolyn Pickel, UC IPM advisor for Sacramento Valley, and with financial support from Department of Pesticide Regulation. The Walnut PMA focused on demonstrating newer mating disruption techniques and a biological IPM system for the codling moth, the chief cause of walnut destruction.

"Our focus is to expand efforts to educate others in the industry and the orchard about reduced-risk strategies and monitoring techniques so they can develop environmentally sound, economical walnut production," says Carolyn.

Carolyn coordinated many on-farm demonstration sites and managed field and team meetings throughout the year. She also wrote and edited the Walnut PMA newsletter that was distributed to walnut growers statewide. In addition, she authored and co-authored several publications about management and control of coding moth.

"Walnut growers have just begun to adopt pheromone mating disruption, and we expect more adoption in the future," says Carolyn. Mating disruption is a technique that uses a female insect's sexual scents, or pheromones, to attract and confuse the males, disrupting the mating process.

The alliance includes University of California research and extension staff, USDA researchers, walnut growers, and the walnut industry, Community Alliance for Family Farmers, PCAs, and Department of Pesticide Regulation.
