By: J. Chaput, OMAFRA, Minor Use Coordinator, Guelph

The Pest Management Regulatory Agency (PMRA) recently announced the approval of URMULE registrations for Presidio Fungicide for control of downy mildew on field and greenhouse basil and downy mildew of hops, and suppression of Phytophthora blight and pod rot and downy mildew on edible-podded beans (incl. edamame) in Canada. Presidio Fungicide was already labeled for use on a number of crops in Canada for control of several diseases.

These minor use projects were sponsored by Agriculture and Agri-Food Canada, Pest Management Centre (AAFC-PMC) in collaboration with the US IR-4 program as a result of minor use priorities established by growers and extension personnel.

The following is provided as an abbreviated, general outline only. Users should be making pest management decisions within a robust integrated disease management program and should consult the complete label before using Presidio Fungicide.

Presidio Fungicide is toxic to aquatic organisms and non-target terrestrial plants. Do not apply this product or allow drift to other crops or non-target areas. Do not contaminate off-target areas or aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers. The use of this product in areas where soils are permeable, particularly where the water table is shallow, may result in ground water contamination. Fluopicolide is persistent and may carryover. It is recommended that any products containing fluopicolide not be used in areas treated with this product during the previous season.
