Join our LAST Thrips Identification Workshop on March 4th in SIMCOE!

As control measures differ depending on the thrips species you’re dealing with, the very FIRST step in learning how to manage thrips effectively is proper species identification.

If you’re interested in having someone in your greenhouse operation learn how to do this (so you don’t have to rely on technical reps or government specialists), then keep reading!

This will be our LAST in-person workshop, so make sure to take advantage of this free learning opportunity!

Biostimulants Part 1: What Are They and What Can They Do?

Ontario greenhouse growers are increasingly experimenting with biostimulants to potentially boost plant quality. Used correctly, these products could help cut fertilizer costs, improve stress tolerance, and enhance overall crop quality.
