The Pest Management Regulatory Agency (PMRA) recently announced the approval of an URMULE registration for Allegro 500F Fungicide for suppression of purple blotch and Botrytis leaf blight on the bulb onion crop subgroup which includes dry bulb onions, garlic and shallots in Canada. The active ingredient fluazinam was already labeled on potatoes, Brassica vegetables, legumes, bushberries, ginseng, carrots, muskmelons, peppers and apples for several important diseases.
This minor use project was sponsored in 2012 by FVGO (Fresh Vegetable Growers of Ontario) as a result of minor use priorities established by growers and extension personnel. The minor use label expansion for Allegro 500F Fungicide is an helpful step towards developing an improved pest management toolkit for these diseases in Canada.
The following is provided as an abbreviated, general outline only. Users should consult the complete label before using Allegro 500F Fungicide.
|Crop(s)||Pest||Rate (L/ha)||Maximum # of applications/year||Pre-harvest interval|
|Bulb onion crop subgroup 3-07||Botrytis leaf blight, purple blotch||1.16||5||7 days|
Allegro 500F Fungicide should be used in an integrated pest management program and in rotation with other management strategies to adequately manage resistance. Do not contaminate aquatic habitats when cleaning or rinsing spray equipment or containers. See label for rotational crop restrictions.
Follow all other precautions and directions for use on the Allegro 500F Fungicide label carefully.
We also wish to acknowledge the personnel of ISK Biosciences Corporation for their support of this registration and the personnel of the Pest Management Regulatory Agency for evaluating and approving this important pest management tool.
