Japanese Beetle (Popillia japonica) adults are starting to take flight in southern Ontario. They have been spotted in Hamilton and Niagara this week. Read on for an updated post on WHAT and WHEN to spray for JB to meet certification requirements if you ship product outside Ontario.
Okay, so Poinsettia don’t really get that many problems. But when issues arise, they can hit a crop fast and hard. Whitefly, Lewis mite, root rots, and nutritional issues can all quickly derail a quality crop.
Here’s a month by month guide on what you should be looking for to prevent small problems from becoming big issues.
Here in Canada, we’ve been talking for years about research on the highly effective method of dipping your poinsettia cuttings in low-risk pesticides to reduce starting whitefly populations.
Thanks to Dr. Rose Buitenhuis (VRIC), Cary Gates (FCO) and BioWorks, the label for BotaniGard WP has now officially been expanded to include dip applications. This now adds to our arsenal (see below for more dip products).
Read on for the current BotaniGard label and how dipping can help improve your Bemisia whitefly program this year, whether you’re using pesticides or biocontrol.
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.

It’s almost that time of year again – time for Japanese beetles to begin their flight and make exporting ornamental plants from Ontario more difficult.
But this year, we have a new biological insecticide is available for managing both the larval and adult stages of Japanese Beetle.
Read more on it’s use and availability.
A new, potentially serious plant virus – the Tomato Brown Rugose Fruit Virus – is moving through crops across Europe and the U.S. As this virus can affect both tomatoes, peppers, and potentially some floral hosts, OMAFRA is running information workshops in Niagara and Leamington to answer grower questions about potential threats to our industry.
Read on for a description of the virus and workshop dates.
