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.

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.
The Japanese beetle season is upon us once again! Adults were spotted this week in Southern Ontario.
Shipping outside Ontario or need to meet the requirements of the JB module for the Greenhouse Certification Program? Not sure what’s required?
This post contains a treatment “decision tree” and a JB product “cheat sheet” to help growers of greenhouse ornamentals.
Navigating the guidelines for exporting plant material out of a Japanese Beetle (JB) zone such as Ontario can be tricky business, especially with upcoming changes to the Greenhouse-Grown Plant Certification Program (GCP; formerly CGCP).
Also not helping is the general lack of information out there regarding proper timing of JB control products. For example, did you know that NO products are considered effective between May 15 and June 15? This could create problems if you’re shipping outside Ontario in the next month and haven’t treated yet.
To make things easier, I’ve created a treatment “decision tree” and a JB product “cheat sheet” for growers of greenhouse ornamentals.
For those of you also growing nursery crops or outdoor ornamentals, check out this post from ONnurserycrops on Japanese beetle-sightings in the area and accepted control measures.
