Minor Use Label Expansion Granted for Quadris Fungicide for Control of Leaf Blights on Celery

J. Chaput, OMAFRA, Minor Use Coordinator, Guelph

The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion for QUADRIS® Flowable Fungicide (azoxystrobin) for control of leaf blights (Cercospora and Septoria) on celery in Canada. Quadris® fungicide was already labeled for management of a variety of diseases on a range of crops in Canada.

This minor use submission was sponsored in 2012 by the Quebec Horticultural Council (CQH) in response to minor use priorities identified by producers and extension personnel in Canada.

Leaf blights of celery are the most common disease problem faced by celery producers and have been identified annually as a key minor use priority.

The following is provided as a general, abbreviated outline only. Users should consult the complete label before using Quadris® Flowable Fungicide.

For control of Cercospora and Septoria leaf blight on celery, apply 0.672 – 1.12 L per hectare of Quadris in sufficient water to provide thorough coverage. Begin applications prior to disease development and apply at 7 – 12 day intervals. Do not use more than 3 applications per season and do not apply less than 1 day before harvest of celery.

Quadris® fungicide should be used in an integrated pest management program and in rotation with other management strategies. Follow all other precautions and directions for use on the Quadris® fungicide label.

We wish to acknowledge the personnel of Syngenta Crop Protection Canada Inc. for their support of this registration and the personnel of the Pest Management Regulatory Agency for evaluating and approving this important pest management tool.
