Biocontrols Event Draws Rave Reviews

biocontrols2015conferenceMore than 400 growers, pest control and certified crop advisers, researchers, government regulators, and suppliers gathered in Fresno earlier this month for the Biocontrols 2015 Conference & Tradeshow.

This event — a first of its kind focused solely on the use of biopesticides and other biocontrols — brought attendees together for an in-depth discussion on the latest tools available, “how-to” production topics, market trends, and regulatory issues. Attendees also spent time with nearly 40 exhibitors learning about new technologies, techniques and services that are making the use of biocontrols more mainstream with growers all over the country.

“Ours is a very economic and science-based business culture,” said Gary Schulz, the new CEO of the California Association of Pest Control Advisers (CAPCA). “We encourage our pest control advisers (PCAs) to use all of the tools they have available, both traditional chemicals as well as many of the new softer materials including biopesticides and biocontrols.”


Sessions at the event covered a broad range of topics from crop-specific production techniques for fruit, vegetable, and ornamental crops to broader industry issues, including a spirited discussion on maximum residue levels (and how biocontrols can help growers stay under tolerance limits for sales to both U.S. and international markets).

“EPA is trying to develop a more predictable regulatory process for these materials,” said Robert McNally, director of EPA’s Office of Pesticide Programs, Biopesticides and Pollution Prevention Division.

Surendra Dara, Strawberry and Vegetable Crops Advisor and Affiliated IPM Advisor with University of California Cooperative Extension, pointed out that as more useful biological products are becoming available, the technology is beginning to deal a little more successfully with the perception issues that have plagued it in the past. But there’s still work to be done, he said.

“Biopesticides do not have to be just for organic production. These are tools for conventional growers, too,” he said. “These materials do work.”

The World Is Changing
It’s critical that biopesticides work, because increasingly, growers are going to want to look at them to control pests more “softly.” For one thing, produce buyers, especially the large grocery chains, are increasing their scrutiny of conventional pesticides’ maximum residue levels (MRLs).

But it’s not just the food industry that is examining pesticide levels, said Brian Leahy, the director of the California Department of Pesticide Regulation. Everyone from the bureaucrats at the various water quality control boards to the activists with wildlife groups are keeping a close eye on what materials growers are using.

“We spend a lot of time telling people that California food is safe,” he said. “The rest of society is really looking at registration.”

Using biocontrols requires that growers change their mindset, noted Brad Higbee, director of entomology for the largest tree fruit and nut grower in the world, Paramount Farming Co. of Bakersfield, CA.

Higbee should know, as earlier in his career when he was with the USDA-Agricultural Research Service in Washington, he helped pioneer the use of pheromone mating disruption to control Public Enemy No. 1 in the state’s apple orchards, codling moth.

Since moving to California and going to work for Paramount, Higbee has employed mating disruption on the most damaging pest of almonds, navel orangeworm, and has enjoyed great success. In fact, he said mating disruption acreage on California almonds will double this year, because it’s working on high-pressure blocks.

“It’s hard for a grower to use no pesticides,” he said, “but we’re using mating disruption only, and it works.”
