Jim Chaput, OMAFRA, Minor Use Coordinator, Guelph

The Pest Management Regulatory Agency (PMRA) recently announced the approval of an URMULE registration for Prism® Herbicide for control of weeds on caneberries (raspberries, blackberries) in Canada. Prism® herbicide was already labeled for use on a number of crops in Canada for control of weeds.

This minor use project was submitted by Agriculture & Agri-Food Canada, Pest Management Centre (AAFC-PMC) in 2013 as a result of minor use priorities established by growers and extension personnel.

The following is provided as an abbreviated, general outline only. Apply as a single early, post-emergence application to actively growing weeds to caneberries that have gone through at least one growing season.  Users should consult the complete label before using Prism® herbicide.

Rate (g/ha)
PHI (days)
Caneberries, crop sub-group 13-07A
Labeled weeds
60 g + non-ionic surfactant
1 (One) or 2 (Two) if banded at 50% band or less

Prism® herbicide is toxic to non-target terrestrial plants and aquatic organisms. Do not apply this product or allow drift to other crops or non-target areas. The use of this chemical may result in contamination of groundwater particularly in areas where soils are permeable and/or the depth to the water table is shallow. Do not contaminate off-target areas or aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers.

Follow all other precautions and directions for use on the Prism® label carefully.
