Although the invasive pest Thrips parvispinus continues to threaten tropical ornamental crops, the good news is that the sky isn’t falling. Producing crops like mandevilla, schefflera and hoya is still possible, at least in a closed greenhouse setting.
Although developing a reliable biological control program for this pest is probably a few years off, a suite of pesticides is available in the U.S. and Canada to successfully manage T. parvispinus.
This post covers these pesticides, their relative efficacy and demonstrates outcomes when used in an 8 month on-farm trial in mandevilla.
Join us for a GrowON webinar tomorrow (Tuesday May 30th) on potential solutions for Thrips parvisipinus from “boots on the ground” folks. This includes technical reps, industry consultants, and extension specialists.
Webinars on Thrips parvispinus are coming fast and hard lately, as scientists and extension agents try to get you the very latest information on this serious pest of ornamentals and peppers.
Join us for a GrowON webinar next Tuesday on potential solutions for this pest from “boots on the ground” folks. This includes technical reps, industry consultants, an your friendly neighborhood extension specialist in Ontario.
As Ontario sources much of its plant material from Florida, it’s a good idea to exercise caution, even on non-tropical plants. The known host range of this pest is evolving, and thrips have the potential to hitch-hike on less-preferred plant hosts and spread to more preferred hosts in your greenhouse.
Read on for information on the situation in Florida and what you can do to help protect your greenhouse from this pest.
