Got thrips? Check out this exciting new resource!

It’s an exciting time for Floriculture IPM!  I am VERY pleased to announce the launch of the all new GreenhouseIPM 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: (rose.buitenhuis@vinelandresearch.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.
