Outside of Ontario?  Well, this still may apply to you, as a recent study in France also indicated that up to 47% of pest thrips in floriculture greenhouses were Onion thrips.  So, this issue could be wide-spread.

My last post covered the extent of the problem in Ontario’s industry.  This post will help you identify if YOU are dealing with Onion thrips (OT) along with Western flower thrips (WFT), and what to do about it.
