J. Chaput, OMAFRA, Minor Use Coordinator, Guelph

The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion for NOVA 40W FUNGICIDE (myclobutanil) that includes control of powdery mildew on crop group 9, cucurbits, in Canada. NOVA 40W FUNGICIDE was already labeled in Canada for management of a number of diseases on apples, pears, grapes, cherries, peaches, Saskatoon berries, strawberries, greenhouse tomatoes, peppers and cucumbers, asparagus and ornamentals.

These minor use projects sponsored by Agriculture & Agri-Food Canada, Pest Management Centre (AAFC-PMC) were originally submitted in 2001 and 2003 in response to minor use priorities identified by producers and extension personnel in Canada.

This registration will provide producers with another pest management tool to help manage this common disease problem in Canada. The following is provided as a general, abbreviated outline only. Users should consult the complete label before using Nova 40W fungicide.

Crop group Rate (g per ha) Comments** PHI
Cucurbit vegetables, CG9 175 Max. 2 applications per season/ 10 – 14 day application interval 3 days

** consult label for details regarding appropriate water volumes, REIs and timing of applications

Nova 40W Fungicide should be used in an integrated pest management program and in rotation with other management strategies. This product is hazardous to fish. Do not contaminate any body of water by direct application, cleaning of equipment or disposal of wastes. Do not apply directly to water or wetlands. Do not apply when weather conditions favour drift or run‑off from areas treated. Follow all other precautions and directions for use on the Nova 40W Fungicide label.

We wish to acknowledge the personnel of Dow AgroSciences for their support of this registration and the personnel of the Pest Management Regulatory Agency for evaluating and approving this important pest management tool.
