The Pest Management Regulatory Agency (PMRA) recently announced the approval of an URMULE registration for Confine Extra fungicide for suppression of bacterial leaf spot (Xanthomonos campestris pv vitians) in Canada. Confine Extra fungicide was already labeled for use on a number of crops in Canada for several different diseases.


The minor use project was submitted 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 disease management program and should consult the complete label before using Confine Extra fungicide.
