Over the past few years, we seem to be battling a whole new posse of thrips species. First it was onion thrips moseying on up into our chrysanthemums and gerbera. Then, it was Parvispinus, which was like a runaway train in our tropicals. Now, it’s Japanese flower thrips (Thrips setosus), riding into town on crops like hydrangea.
To make sure growers have the latest information on these pests, GrowON is running a 3 part webinar series on thrips besides western flower thrips. The first installment will be on Japanese flower thrips on August 20th. Read on for how to register for this free webinar.
GrowON’s “More than just Westerns” Thrips Webinar Series
What: A series of webinars designed to bring you the latest information on thrips we are battling in Ontario greenhouses that aren’t western flower thrips. We’ll talk about pesticide and biocontrol solutions for onion thrips, Thrips parvispinus, and Japanese flower thrips. Knowing how to ID these pests, and how their control differs from western flower thrips, is key to a comprehensive thrips management strategy.
