The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for Allegro 500F agricultural fungicide for control of dead arm (Phomopsis viticola) and suppression of anthracnose (Elsinoe ampelina) on wine grapes in Canada. Allegro 500F agricultural fungicide was already labeled for management of diseases on a wide range of crops in Canada.

These minor use proposals were submitted by Agriculture & Agri-Food Canada, Pest Management Centre (AAFC-PMC) 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 disease management decisions within a robust integrated disease management program and should consult the complete label before using Allegro 500F agricultural fungicide.

TOXIC to aquatic organisms and non-target terrestrial plants. Observe spray buffer zones specified under DIRECTIONS FOR USE. To reduce runoff from treated areas into aquatic habitats avoid application to areas with a moderate to steep slope, compacted soil, or clay. Avoid application when heavy rain is forecast. Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative filter strip between the treated area and the edge of the water body. Fluazinam is persistent and may carry over. It is recommended that this product not be used in areas treated with any products containing fluazinam during the previous season.

Follow all other precautions, restrictions, and directions for use on the Allegro 500F Agricultural Fungicide label carefully.
