Summer School: Lessons learned from another hot, humid Ontario summer

Happy first day of fall! It was a dry, sweltering summer across Ontario, and I’ve heard from some growers that it was the most challenging summer they could recall in recent memory based on the heat alone.  Oppressive heat and humidity pack a punch that leaves everyone feeling sluggish – you, your staff and your plants.  While we won’t complain too loudly (winter’s coming!), learning from this year’s challenges will help in summers to come as we experience more extreme weather.

Fig. 1. Leaf mines on gerbera leaves.

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.
