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.

Poast Ultra herbicide is toxic to aquatic organisms and non-target terrestrial plants.  Do not apply this product or allow drift to other crops or non-target areas. Do not contaminate off-target areas or aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers. 

Follow all other precautions, restrictions and directions for use on the Poast Ultra herbicide label carefully. 

For a copy of the new minor use label contact your local crop specialist, regional supply outlet or visit the PMRA label site.
