The work of the Production Research Committee is never done. Here are some of the challenges that lie ahead:

Plant bugs. Without the use of dormant sprays, leaffooted bug and stink bug populations are being treated with OPs and pyrethroids in the spring. Will this disrupt IPM systems? What effect will this have on surface water and air quality?

Growers need a monitoring program to determine the need for and timing of treatments for plant bugs.

Spider mites. Is resistance developing for abamectin? How effective are newer miticides, and what is their impact on predatory (beneficial) mites? Which miticides should be used at different times of the season?

How can growers predict in-season spider mite populations and areas where mite problems could flare?

Answers to these and many other questions will be forthcoming, thanks to the growers whose leadership 40 years ago led to the cumulative investment to date of $19.8 million to address production issues and needs of California’s almond growers.
