Prowl H2O herbicide is now registered for control of labelled weeds in garlic, dry bulb shallots in Canada and on transplanted leeks grown on muck soil in eastern Canada and British Columbia. The herbicide was already labeled for use on a number of crops in Canada for 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 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 Prowl H2O herbicide.

Prowl H2O 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. Do not apply Prowl H2O herbicide more than once in two consecutive years.

Follow all other precautions, restrictions and directions for use on the Prowl H2O herbicide label carefully.
