The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for PROWL® H2O Herbicide for control or suppression of labelled weeds listed pome and stone fruits (new and established plantings) in Canada. PROWL® H2O Herbicide was already labeled for management of weeds on a wide range of crops in Canada. These minor use proposals were submitted by Agriculture & Agri-Food Canada, Pest Management Centre (AAFC-PMC) 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 weed management decisions within a robust integrated weed management program and should consult the complete label before using PROWL® H2O Herbicide.
