Herbicide label expanded for control of weeds on garlic, shallots, leeks

November 28, 2019  By ONvegetables

The Pest Management Regulatory Agency (PMRA) has approved a minor use label expansion registration for Prowl H20 herbicide for the control of labeled weeds on garlic and dry bulb shallots in Canada as well as on transplanted leeks grown on much soil in Eastern Canada and British Columbia.

The herbicide was already labeled for use on a number of crops in Canada for the control of several weeds.

These minor use projects were submitted by Agriculture & Agri-Food Canada (AAFC-PMC) as a result of minor use priorities established by growers and extension personnel.


The above table (click to expand) serves 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 Prowl H2O.

Prowl H20 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. Do not apply the herbicide more than once in two consecutive years. Follow all other precautions, restrictions and directions for use on the label carefully.
