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.
Weekly-mum producers have seen higher-than-normal spider mite levels coming in on cuttings from the U.S. recently. This might impact seasonal potted-mum growers as well.
You know the old rhyme: “April showers bring May flowers, but what do May flowers bring? Aphids“. Or sometimes it seems that way, anyways, with Spring bedding crops.
