For those of you that missed my webinar on “Thrips Control: from Propagation to Pocketbook”, it is now available for free on the Greenhouse Canada Magazine website.

As much as we all hate thrips, there are, frankly, worse problems to have. And it’s name is Leafminer. These flies cause just about the ugliest damage we see in floriculture (Fig. 1), and they have incredible pesticide-resistance capabilities. Outbreaks seem to go in cycles, and I’ve had quite a few gerbera and mum crops come across my desk with leafminer this past 2 weeks.
This post covers chemical options (BawHawHawHa!!! Oh… Sorry… I’ll get myself under control now) and non-chemical options for leafminer, as well as how their control fits into the big picture in greenhouse IPM programs.
You’ve likely noticed by now that thrips populations are especially high because of the hot, dry summer. Many growers are noticing their usual biocontrol programs can’t keep up, and further defenses are needed this year.
The use of mass trapping strategies may be the key to getting an edge over thrips. This post discusses the latest research on mass trapping of thrips in ornamentals, including patterned sticky tapes and the use of pheromones.
