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.
It seems there is never a dull moment in the greenhouse ornamental industry these days. From transitions to new crops, new export requirements, to novel pest problems, the industry has seen a lot of change….and it’s not over yet.
The industry is also going to be facing changes regarding some commonly used chemical products. Here is the latest on potential revisions to the list of chemical tools we have access to in Canadian floriculture.
This is guest post was written by Cary Gates, Pest Management Director at Flowers Canada Growers.
Ever needed just to quickly look up a rate for a particular pesticide, or see if it’s compatible with your bio program, only to get lost on Google or get frustrated by the numerous tables in Pub 370? Well, me too.
Read on for resources to make accessing pesticide information quicker and easier for Ontario’s floriculture sector.
These include a new mobile app for ALL registered pesticides, as well as a downloadable spreadsheet you can tailor to your needs.
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.

That’s right! As of today, flower growers have 2 new weapons against fungal diseases at their disposal. Heritage MAXX (azoxystrobin) and Medallion (fludioxonil) are now registered for use in outdoor and greenhouse ornamentals.
Heritage (a Group 11 fungicide) is a systemic fungicide, and is appropriate for control of Pythium, Grey mould (aka Botrytis blight) and Rhizoctonia. It can also be used for foliar diseases such as Powdery Mildew, Downy mildew, Rust, Anthracnose and Alternaria Leaf Spots. You can find the new label here: HeritageLABEL2016.
Medallion (a Group 12 fungicide) is a contact fungicide, and is appropriate for control of root rots such as Fusarium, Rhizoctonia, and Black Root Rot (Thielaviopsis) when applied as a drench. It can be applied foliarly for Grey Mould, Anthracnose Leaf Spot and Rhizoctonia Stem Rot. MedallionLABEL2016.
Both are broad-spectrum fungicides that can be used curatively or prophylactically.
As with any chemical control product, make sure to read and follow the label carefully prior to use.
