The Pest Management Regulatory Agency recently announced the approval of a minor use label expansion registration for Revus® Fungicide for control of downy mildew of basil and phytophthora blight and root rot of ginseng.
Revus® Fungicide was already approved in Canada on Brassica vegetables, several bulb vegetables, several leafy vegetables, cucurbit vegetables, fruiting vegetables, potatoes, grapes and hops.
The following is a general, abbreviated outline of the new disease registrations on the Canadian label for Revus® Fungicide. For detailed instructions consult the full Revus® Fungicide label.
Basil (field and greenhouse)
For control of downy mildew, apply as a foliar spray 583 ml/ha beginning prior to disease development and continue on a 7 day interval in appropriate rotations. Do not apply Revus sequentially – always rotate with other registered products from different fungicide groups. Apply in a spray volume of 95 – 280 L per ha. Maximum of 4 applications per year with a 1 day pre-harvest interval.
For control of Phytophthora blight and root rot, apply as a foliar spray and/or drench at 583 ml/ha beginning prior to disease development and continue on a 7 day interval in appropriate rotations. Drench applications are required to control root rot. Do not apply Revus sequentially – always rotate with other registered products from different fungicide groups. Apply in a spray volume of 470 – 1,400 L per ha. Maximum of 4 applications per year with a 3 day pre-harvest interval.
Revus® Fungicide should be used in an integrated disease management program and in rotation with other management strategies. Follow all other precautions and directions for use on the Revus® Fungicide label.
These minor use projects were co-sponsored by the Agriculture & Agri-Food Canada, Pest Management Centre (AAFC-PMC) and the U.S. IR-4 program between 2008 and 2009 in response to minor use priorities identified by producers and extension personnel. We thank Jim Chaput, OMAF and MRA Minor Use Coordinator and the personnel of Syngenta 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.
