Jim Chaput – OMAFRA, Minor Use Coordinator
The Pest Management Regulatory Agency (PMRA) recently announced the approval of minor use label expansion registration for Prowl® H2O Herbicide for control of labeled weeds on transplanted field tomatoes grown in mineral soil in Canada. Prowl® H2O Herbicide was already labeled for use on a number of crops in Canada for control of several weeds.
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 weed management decisions within a robust integrated weed management program and should consult the complete label before using Prowl® H2O Herbicide.
