In this webinar Dr. Jeanine West will share water quality management strategies based on her expertise and preliminary research findings. Time will be allocated for Q&A.

High pesticide resistance in species like western flower thrips and Bemisia whitefly is something we’ve learned to work around. But how can we avoid resistance in pest species where we still rely on pesticides? For pests like spider mites and powdery mildew, this is an ongoing battle.
