Now that the warm weather is finally upon us, it’s time to start worrying about thrips control.
What we’ve learned over the years is that pesticides just don’t cut it – the only reliable chemical for western flower thrips in Ontario is DDVP, which requires constant application. This means biological control is your best bet. Here’s a summary of the most effective tools, tricks, and timing, to ensure your biocontrol dollars are well spent.
It’s an exciting time for Floriculture IPM! I am VERY pleased to announce the launch of the all newGreenhouseIPM website! GreenhouseIPM.org presents a compilation of up-to-date information on Integrated Pest Management (IPM) and biological control in greenhouses.
And, as part of the website launch, we are holding a FREE THRIPS WORKSHOP (with a free lunch!). The workshop will cover all the components of thrips IPM and how they fit into a greenhouse production system.
Dates are Nov 23rd (8:30-1pm) OR Nov 30th (8:30-1pm) at Rittenhouse Hall. Please RSVP Rose Buitenhuis: (email@example.com or 905-562-0320 x749). SPACE IS LIMITED SO RESERVE YOUR SPOT NOW!
The most current information on thrips and whitefly IPM is now at your fingertips at greenhouseipm.org.
GreenhouseIPM.org provides detailed descriptions of pests, biocontrol agents and detailed instructions on how best to use biocontrols within an IPM program.
Its initial format it focuses on two key pests – whiteflies and thrips – and their control. The site will evolve to encompass all common insect and mite pests, as well as diseases, in greenhouse crops.
