Poast Ultra Herbicide Registered for Use on Basil

By Jim Chaput, Minor Use Coordinator, OMAFRA

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 basil (fresh and dried) 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.

Crop(s) Target Rate (L/ha) Application Information PHI (days)
  Basil (fresh and dried)   Labeled grassy weeds   Maximum of 1.1 Apply up to 2 applications per year not exceeding a total maximum application rate of 1.1 L/ha per season. Allow a minimum of 14 days between applications.   14

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.
