Upcoming GrowON Webinar on May 30th! “Potential Solutions for Parvispinus: Lessons from the Field”

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.

Read on for more information and how to register.

Potential Solutions for Parvispinus: Lessons from the Field


Previous webinars (from the University of Florida on May 4th and the Horticultural Research Institute on May 10th) have brought you critical information on the history and spread of this pest, monitoring tips, and potential pesticide options from lab-based tests.

With this webinar, we want to give you potential IPM solutions based on field observations and on-farm trials. Although we are a long way away from a tried-and-true IPM program for T. parvispinus, every success – and failure – in the field can help guide other growers.


Tuesday May 30th, from 12-1:30pm.
