The Pest Management Regulatory Agency (PMRA) recently announced the approval of an URMULE registration for Pristine® Fungicide for suppression of downy mildew and control of powdery mildew in conventional hops production in Canada. Pristine® Fungicide was already labeled for management of diseases on other fruit, vegetables and ornamental crops in Canada.
This minor use project was sponsored in 2010 by the minor use office of OMAF as a result of minor use priorities established by growers and extension personnel. The minor use label expansion for Pristine® Fungicide is an helpful step towards developing an improved disease management toolkit for conventional hops in Canada.
The following is provided as an abbreviated, general outline only. Users should consult the complete label before using Pristine® Fungicide.
Pristine can be applied at a rate of 0.105 kg per 100 litres of dilute spray with a maximum of 1524 litres of dilute spray per hectare. Note that this product is labelled for control of powdery mildew and suppression only for downy mildew. Begin applications prior to disease development; and use a 10-14 day interval. A maximum of 3 applications of Pristine are permitted per year. Do not apply within 46 days of harvest. Do not enter or allow worker entry into treated hops during the restricted-entry intervals (REI) of 8 days for hand set irrigation, 46 days for harvesting and 12 hours for all other activities.
Pristine® Fungicide should be used in rotation with other management strategies to adequately manage resistance. This product is toxic to aquatic organisms, non-target terrestrial plants and small wild animals. Do not contaminate aquatic habitats when cleaning or rinsing spray equipment or containers. Follow all other precautions and directions for use on the Pristine® Fungicide label carefully.
We thank Jim Chaput, OMAF and MRA Minor Use Coordinator for making this submission, the personnel of BASF 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.
