DUAL II MAGNUM® Herbicide label expanded via Minor Use Program to help manage labelled weeds on Crop Subgroup 13-07A, Caneberries

J. MOSIONDZ, OMAFRA, Minor Use Coordinator, Guelph

The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for DUAL II MAGNUM® Herbicide for control or suppression of labelled weeds in crop subgroup 13-07AA, Caneberries (new and established plantings) in Canada. DUAL II MAGNUM® Herbicide was already labeled for management of weeds on a wide range of crops in Canada. These minor use proposals were 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 DUAL II MAGNUM® Herbicide.

Rate (L product/ha)
Application Information
PHI (days)
CG 13-07A (new and established plantings)
Labelled Weeds
Apply to the soil in the early spring as a banded application to both sides of the plant row prior to weed emergence. Make only one application per year. 
Apply in a 150 L water/ha minimum. 

TOXIC to aquatic plants and non-target terrestrial plants. Observe buffer zones specified under DIRECTIONS FOR USE. To reduce runoff from treated areas into aquatic habitats avoid application to areas with a moderate to steep slope, compacted soil, or clay. Avoid application when heavy rain is forecast. Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative strip between the treated area and the edge of the water body. For the protection of aquatic plants, overspray or drift to important wildlife habitats such as wetlands, sloughs or dry slough borders and water bodies should be avoided. Leave a buffer zone of 29 metres between the last spray swath and the edge of any of these habitats. Drift to emerging vegetation or newly emerged vegetation in shelterbelts or woodlots should be avoided. For tank mixes, consult the label(s) of the tank mix partner(s), and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture.

This product contains a petroleum distillate which is moderately to highly toxic to aquatic organisms. Avoid contamination of aquatic systems during application. Do not contaminate these systems through direct application, disposal of waste or cleaning equipment.

Follow all other precautions, restrictions, and directions for use on the DUAL II MAGNUM® Herbicide label carefully.
