Jim Chaput, Minor Use Coordinator
The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for Prowl® H2O Herbicide for control of labeled weeds on direct seeded or transplanted cabbage, cauliflower and broccoli grown on mineral soil in Canada. Prowl® 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 Ontario 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 pest management program and should consult the complete label before using Prowl® H2O Herbicide.
| Crop(s) | Target | Rate (L/ha) | Application Information | PHI (days) |
| Direct seeded or transplanted cabbage, cauliflower and broccoli | Labeled weeds | 2.46 | Apply once as a directed spray to soil surface between rows of cabbage, cauliflower and broccoli when crop is at the 2-4 leaf stage for both direct seeded and transplanted crops | 60 (broccoli) 70 (cabbage, cauliflower) |
Prowl® 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 Prowl® Herbicide label carefully.
