Jim Chaput, Minor Use Coordinator
The Pest Management Regulatory Agency (PMRA) recently announced the approval of an URMULE registration for Prowl® H2O Herbicide for control of labeled weeds on direct seeded, green (bunching) onions grown on muck soil in eastern Canada and British Columbia. Prowl® H2O Herbicide was already labeled for use on a number of crops in Canada for control of weeds.
The minor use project for green onions grown on muck soil was sponsored by Agriculture and 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 Prowl® H2O Herbicide.
| Crop(s) | Target | Rate (L/ha) | Applications | PHI (days) |
| Direct seeded, green (bunching) onions grown on muck soil | Labeled weeds | 6.6 | Apply a single application between the loop stage and flag stage of green onions in a minimum of 200 L water per ha | 30 |
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.
Follow all precautions and detailed directions for use on the Prowl® H2O Herbicide label carefully.
