Save on Energy’s Expanded Energy Management Program – EMIS Updates for Greenhouse Operators

Image
This post was originally published on the ongreenhousevegetables.ca blog on  May 21, 2026  by  Averie Mastronardi Energy management information systems (EMIS) can reduce energy consumption and GHG emissions, lower utility costs, improve operational performance, and strengthen decision‑making. Receive funding of up to $50,000 or $250,000, depending on your annual energy consumption, for the installation of an EMIS through Save On Energy’s  Expanded Energy Management program . The EMIS funding ends March 31, 2027, and incentive payments must be made by this date. To ensure your incentive is available, we recommend that organizations aim to complete approved projects by the end of 2026.  What Funding Can you Receive Through the EMIS Program? Facilities with an annual baseline energy consumption of less than or equal to 400,000 GJ (all fuels) are eligible to receive $50,000. Facilities with an annual baseline energy consumption of gr...

Growing Roses? Export Rules to the U.S. Have Changed.

Image
In the efforts to prevent a quarantinable strain of Ralstonia from entering the United States, USDA-APHIS has changed importation rules for rose material for planting. This includes rose material coming from Canada. Under the new federal order, roses (Rosa spp.) grown in Canada must now have been grown entirely within Canada or the U.S. . This includes root stock and graft material. This is to reduce a potential pathway for Ralstonia solanacearum Race 3 biovar 2 (Rs R3bv2) into the U.S., which can devastate solanaceous crops such as potato and tomato, as well as geraniums. Read on for more details about RS R3bv2 and the new export regulations. What is Rs R3bv2 ? Rs R3bv2 is a strain of bacterium of Ralstonia solanacearum that is particularly pathogenic, causing vascular disease of a wide variety of plants . Other races of this bacteria are endemic to the United States (Race 1) or are specific to hosts not grown in North America (e.g. bananas), and are...

Your Yearly Reminder of Japanese Beetle Requirements: Get Those Treatments on Before May 15!

Image
Anyone following this blog for the last few years knows I like to remind y’all to make sure you treat your plants for Japanese beetle before May 15! This is because NO pesticides are allowed when Japanese beetle (JB) pupae are present (generally, May 15-June 15 in Ontario),which has gotten some growers into a pickle during spring shipping in the past. Note that if you’re a nursery crop grower also treating for boxtree moth, you may surpass the maximum allowed applications or rate of Acelepryn per year if you also need to treat for JB . In that case, it might be better to time your treatments for JB in order to use intercept (imidacloprid) instead. So make sure to check out the pesticide timing chart in the JB Infographic in the full post. This year, I’ve updated the JB Decision Tree and Infographic to include shipping requirements to different areas in the United States . So, if you or your staff need more clarification on any of these points, make ...
