Incorporating Biological Control of Spider Mites into Tomato Pest Management Programs

This webinar took place on March 1, 2021.

About the Webinar

In this webinar you will learn about how to manage spider mites in tomatoes and other vegetables using biological control, with an emphasis on the predatory mite Phytoseiulus persimilis. We will review the various natural enemies attacking spider mites, and factors impacting their efficacy. We will also present data from experiments conducted in commercial tomato fields to illustrate how effective these predators can be and how to best incorporate them into a farming system. This includes when and where to release P. persimilis in your fields, how to conserve them with smart insecticide use, and lessons from successes and failures. We will also demonstrate how to rear these predatory mites yourself for year-round use (for either field or greenhouse operations) and potential cost savings.
