As suspected, it’s turned out to be a heck of year for Poinsettia. Many growers faced Erwinia, others had rooting issues, and all faced significant pressure from Bemisia whitefly from infested cuttings.

Whitefly and other poinsettia issues are also being discussed at the Niagara Poinsettia Open House on Tuesday, November 20th. This will take place at Jefferys Greenhouse (Plant II) starting at 10 am.

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.
