The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for Phostrol fungicide for suppression of Phytophthora root rot (Phytophthora spp.) on hazelnuts in Canada. Phostrol fungicide was already labeled for management of diseases on a wide range of crops in Canada. This minor use proposal was submitted by the British Columbia Ministry of Agriculture, Food, and Fisheries 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 Phostrol fungicide.

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 strip between the treated area and the edge of the water body.

Follow all other precautions, restrictions, and directions for use on the Phostrol fungicide label carefully.
