J. MOSIONDZ, OMAFA, Minor Use Coordinator, Guelph

The Pesticides Regulatory Directorate (PRD), formerly known as the Pest Management Regulatory Agency (PMRA), recently announced the approval of a minor use label expansion for Pyganic® insecticide for control of aphids, leafhoppers, climbing cutworms and cabbage looper on Crop Group 25 Herbs and Crop Group 26. Pyganic® insecticide was already labelled for management of insects on a wide range of crops in Canada. These minor use proposals were submitted by Agriculture and AgriFood Canada’s Pest Management Centre as a result of minor use priorities established by growers and extension personnel across Canada.

Lavender Crop Update – Preparing for the Season – April 17, 2026

Posted on April 17, 2026 by Sean Westerveld

Winterkill

By now, row covers should have been removed in all lavender-growing areas of the province. Remember that row covers are not meant to protect against spring cold; they are meant to protect against extreme winter cold and drying winds. In the spring, they can act like a greenhouse and cause the plants to advance too early, making them more prone to frost damage in May. It is a good idea to keep them handy, as they can be useful to protect flower buds from late-spring frosts. In that case, they would be put back on for one or two cold nights.

Ginseng Crop Update – Spring Emergence and Product Updates – April 12, 2026

Posted on April 13, 2026 by Sean Westerveld

This is the first crop update of the 2026 growing season.

Emergence and Growing Degree Days

Accumulated Growing Degree Days (Base 5°C) at Delhi up to April 12 are 5 days ahead of the 25-year average, which suggests crop emergence will be ahead of normal. We have accumulated 68 GDD up to this point which was reached on April 18 in 2025, April 9 in 2024, April 14 in 2023, and April 23 in 2022. This is based on air temperatures alone, which doesn’t tell the whole story. This was the first winter in many years with significant frost in the ground. Soil temperatures are more important than air temperatures for determining emergence dates for ginseng, and these may be lagging behind air temperatures a bit compared to previous years. This is because some of the warm air earlier in the spring would have been needed to melt the frozen soil without contributing to ginseng growth. However, if the forecast for very warm day and night temperatures this week is accurate, by the end of Saturday, April 18, GDD may be at the same stage it is normally at on May 2, a full two weeks ahead of normal. After that time, GDD accumulation may slow for a few days as temperatures drop below normal again. Given all of this, expect ginseng to emerge ahead of normal, unless there is a prolonged period of below normal temperatures ahead of emergence.

Join Cornell Cooperative Extension on Thursday, March 5, 2026 from 1-2 pm EST to learn about the Cornell African Eggplant Research Project. African eggplant, also known as Bitterball, Garden Egg, Kittley and other names, is an important crop for many members of our community with heritage from regions such as sub-Saharan Africa, Southeast Asia, and Brazil. Since 2024, the Cornell African Eggplant Research Project has been collaborating with growers and community partners across New York to develop high-quality varieties adapted to the Northeast U.S. In this meeting, information will be shared about growing and preparing African eggplant, highlight research to date, and invite partners to collaborate in the 2026 participatory breeding and variety selection efforts.

COST and REGISTRATION

FREE! Register online to receive the Zoom link. The Zoom link will be in the email confirmation you receive after registering.
