Integrated Pest Management strategies to reduce chemical pesticides in strawberry

What Has ANR Done?Surendra Dara, UCCE Advisor for strawberry and vegetable crops, has led large-scale field studies to evaluate the potential of integrating of botanical and microbial pesticides with current pest management practices to develop environmentally sustainable pest management strategies. The studies were carried out on commercial strawberry fields at Manzanita, Goodwin, and Sundance Berry Farms in Santa Maria from 2012 to 2015.
Reduce pests by incorporating non-chemical alternatives into pest managementThe results of the studies demonstrate that existing and new chemistries, as well as combinations of botanical and microbial control options, are available and effective. The rotational programs in 2013–2015 tested 33 different treatment options. While some were more effective than others at reducing pest populations, the results demonstrate that incorporating non-chemical alternatives can have a significant impact. It was possible to reduce the number of chemical insecticide applications, and lower rates of chemical pesticides to reduce pests, while helping manage insect resistance to pesticides. These results also underscore the role of non-chemical alternatives beyond organic agriculture and their potential in conventional cropping systems. Incorporating these alternatives into an integrated pest management strategy reduces the reliance on effective chemical pesticides, which could become ineffective if overused.

Clientele Testimonial“These studies are important for us to find out effective chemical and non-chemical options for managing strawberry pests. We recognize the importance of IPM strategies to reduce resistance problems, and Surendra’s studies provide critical information necessary to improve strawberry IPM.” Dave Murray, Andrew & Williamson Fresh Produce
“[Based on Dr. Dara’s research], I have incorporated [biological insecticide] into my spray program to control these pests with very little mortality to my predatory mites. I have had significant success in my organic fields. [Dr. Dara’s] work is important to me and has changed the way I farm my berries.” Rod Koda, Shinta Kawahara Co.
