The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for POAST® ULTRA Herbicide for control of labeled weeds on green onions in Canada. POAST® ULTRA Herbicide was already labeled for management of grassy weeds on a wide range of crops in Canada.
This minor use proposal was 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 POAST® ULTRA Herbicide.
