IPM in potted mums can be challenging at times, but Ontario has lots of strategies for thrips control in this crop.
New to a thrips biological control program for chrysanthemums, or just need a refresher on the most effective strategies currently being used in the industry? Then watching the Greenhouse Canada Webinar, “Tips for Thrips Control: From Propagation to Pocketbook” is a good place to start.
Keep reading for the webinar link and some chrsysanthemum IPM tips for 2018.

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.

Oedema on the young leaves in this begonia basket.
Oedema, that physiological disorder that appears during periods of low light and high humidity. There’s been quite a bit of it reported in Ontario greenhouses this spring, and unfortunately it’s related to the long rainy (or snowy!) spring we’ve been having. If you’ve noticed salt-like crystals, odd tumour-like growths or water-soaked spots on either side of your plant leaves this disorder might be the culprit.
The disorder affects a wide variety of greenhouse ornamentals. It’s usually noticed in spring crops like sweet potato vine (ipomea), geranium, begonia and/or petunia. Continue reading “Oh dear! It’s Oedema.”

Although native bees and honeybees may just be starting to gather strength and are beginning to fly outside, other “B’s” have been of growing concern in the greenhouse for some time now.
These include common spring bedding crop problems like Botrytis cinera (aka grey mold), Broad mites, and leaf burn (from a variety of causes).
Keep reading for tips on how to manage these issues during this time of year.

Starting on April 3, 2018, producers, processors, and other businesses can apply for cost-share funding through the Canadian Agricultural Partnership .
Similar to previous programs (such as Growing Forward 2), this is a new five-year commitment by Canada’s federal, provincial and territorial governments that will support Canada’s agri-food and agri-products sectors.
Keep reading for more information on this program, or talk to your local OMAFRA or OSCIA representative.
