Managing Pesticide Resistance in Greenhouse Crops

With July being the beginning of poinsettia season, as well as the time growers are starting many tropical plants for next spring, it’s time to be thinking about managing pesticide resistance. Pesticide resistance readily develops in populations of key greenhouse pests, including Bemisia whitefly, spider mites, and more. So how do we avoid an uphill run on the resistance treadmill?

Hannah Fraser, Horticulture Entomologist with OMAFA, shared her decades of experience battling resistance issues in fruit crop pests in a GrowON webinar recorded last summer. For those that missed it, I thought now would be a good time to post the video on the blog. (As always, you can find all of our previous GrowON webinars on the ONFloriculture Youtube channel.) Keep reading to watch the video as well as links to other resources on resistance management.
