Peach leaf curl

 

The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for Syllit fungicide for control of peach leaf curl on peaches and nectarines and cherry leaf spot on cherries in Canada. Syllit fungicide was already labeled for use apples and pears in Canada for control of scab.

 

This minor use project was submitted by Ontario 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 pest management decisions within a robust integrated pest management program and should consult the complete label before using Syllit fungicide.
