T’is poinsettia sticking season once again, and the question always comes down to the same thing: do I use chemicals to control Bemisia whitefly and hope it works this year? Or do I switch to biological control? Here we show some head to head comparisons that can help you decide.
An in-depth discussion of this topic was also captured by MSU’s “Bug Bites” last year, and I’ve included the video below.
Interested in learning more about effective spraying in controlled environment agriculture? Tune in at noon this Thursday with host Dr. Fadi Al-Daoud and co-host Dr. Andrew Wylie for a presentation by OMAFRA’s application specialist Dr. Jason Deveau specific to closed environments:
Pesticide resistance is something most growers have run into at some time or another. High pesticide resistance in species like western flower thrips and Bemisia whitefly is something we’ve learned to work around. But how can we avoid resistance in pest species where we still rely on pesticides? For pests like spider mites and powdery mildew, this is an ongoing battle.
Three OMAFRA specialists are hosting a series on pesticide resistance that will include question and answer periods after each session. Contributors are Hannah Fraser (Entomologist), Dr. Katie Goldenhar (Plant Pathologist) and Kristen Obeid (Weed Management). Read on for dates and how to register.
With the holiday season almost upon us, it’s time to turn our attention to Spring bedding crops. Although here for a brief window, the diversity of these crops means you’re bound to encounter some sort of disease and insect problems.
One way you can head off issues is to plan and prepare now. This post from January 2020 has important tips on sanitation for common spring crop diseases, dipsandearly sprays to prevent key pests, as well as tips on where to spend your biocontrol dollars.
A new pesticide is available for greenhouse ornamental production in Canada that has shown potential for effective suppression of difficult-to-control thrips and whitefly species.
But to keep this new tool effective, growers will have to use this chemical wisely. Keep reading for efficacy data on ornamental crops and best management practices for incorporating this chemical into your IPM toolbox.
