Japanese Beetle (Popillia japonica) adults are starting to take flight in southern Ontario! They have been spotted in Hamilton and Toronto this week.
Look for these shiny green and copper beetles feeding on grape leaves, roses and many other trees and shrubs. Where possible, homeowners can knock adults into a bucket of soapy water (to smother them). Several insecticides are registered for the adults in greenhouses and nurseries, including BeetleGONE.
European chafer (Amphimallon majale) adults are also starting to emerge. Look for medium brown scarab beetle swarming blooming Linden trees (e.g. Tilia cordata). Historically we see them around Canada day in the Guelph area.
And don’t forget about our little friends, the Rose Chafers (Macrodactylus subspinosus), pictured above. They are also out in full force. These scarab beetles feed on the flowers, fruit and foliage of several ornamentals. The larval stage feeds on roots of grasses and weeds (usually a sod nursery pest). Like most scarab beetles, females are more likely to lay their eggs in sandy soils and will avoid egg laying in clay soils. Insecticides for the grub stage of other scarab beetles will also reduce larvae of rose chafer.
Preventative applications of Intercept and Acelepryn are registered for white grubs in nursery and greenhouse production and the application period begins now. (Above photo: European chafer larval feeding damage).

The first installment of OMAFRA and MLTSD’s monthly webinar series is scheduled for Tuesday, June 22, 12 – 1pm ET. These webinars will occur on the 3rd Tuesday of each month at noon.
Next week’s webinar is: Using Temporary Help Agencies and Employment Standards Webinar
When faced with a labour shortage, many employers in the agriculture sector turn to a temporary help agency (THA) for assistance. But did you know clients of agencies have legal obligations when using a THA? Before speaking with an agency, clients of agencies should find out what their responsibilities are under the ESA.
Thrips got you down? Not sure what you can do to beef up your thrips-management program? Then this new webinar is for you!
Drs. Sarah Jandricic (Ontario Ministry of Agriculture, Food and Rural Affairs) and Rose Buitenhuis (Vineland Research and Innovation Centre) have combined their respective knowledge into a “systems approach” for thrips management.
Want to know what that means, and how it can work for you? Then keep reading!
Nursery and Floriculture Growers, Landscapers and Retail Garden Centres are all working hard to provide the kind of excellence in service and plant material that Ontarians have come to know and expect. As more horticultural businesses are opening up, we thought it would be helpful to review some of the resources that have been developed […]
How do you get help in this day and age when your extension agent or consultant can’t just pop into your greenhouse and look at a problem with you? Although nothing can replace seeing an issue first-hand, there is still a way to get help with your pest and production issues from a distance.
