As anyone battelling whitefly on poinsettia this season can attest to, good pesticide coverage in ornamental crops can be challenging. Hydraulic sprayers are the industry standard, but does that mean they’re the best option? Where does sprayer technology need to go in the future to get growers better results?
This summer, Dr. Jason Deveau, OMAFRA’s official “Spray Guy”, and myself did a trial at a local greenhouse with some experimental equipment to try and answer these questions. The results were intriguing, to say the least.
For all the details on this trial, check out the link to Jason’s blog post, below.

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.
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.
It’s that time of year again where two of our biggest crops cross over: fall pot mums and poinsettia. This means growers have to simultaneously keep an eye on the two biggest pests in the industry: thrips (usually western flower thrips) and Bemisia whitefly.
Up until this point, most of Ontario floriculture growers (and me!) assumed the only pest thrips we were dealing with was Western flower thrips (besides Echinothrips in a few crops like gerbera and poinsettia).
