The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for SELECT® Herbicide for control or suppression of labelled weeds in Rutabaga, Green Onion, and Leeks in Canada. SELECT® 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) and the Ministère de l’Agriculture, des Pêcheries et de l’Alimentation du Québec 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 SELECT® Herbicide.
| Crop(s) | Target | Rate (L product/ha) | Application Information | PHI (days) |
| Rutabaga | Suppression of Control of Labelled Weeds | 0.19 – 0.38 | Apply SELECT post- emergence of weeds and crop using ground equipment. Apply a maximum of two applications per year. If repeat application is required, allow at least 14 days between first and second application. Do not apply more than 0.38 L/ha (90 grams a.i./ha) per crop per season. Apply in a minimum spray volume of 110 L/ha. Ground application only. | 30 |
| Green Onion | Suppression or Control of Labelled Weeds | 0.19 – 0.38 | Apply SELECT post-emergent when the crop is in the 2 to 3 leaf stage. Apply a maximum of one application per season, using ground equipment. Apply in a minimum spray volume of 110 L/ha. Ground application only. | 14 |
| Leek | Suppression or Control of Labelled Weeds | 0.19 – 0.38 | Apply SELECT post-emergent at least 2 weeks after transplanting when crop is well established and has produced one new fully expanded leaf. Apply a maximum of one application per season, using ground equipment. Apply in a minimum spray volume of 110 L/ha. Ground application only. | 14 |
TOXIC to aquatic organisms and non-target terrestrial plants. Observe buffer zones specific under DIRECTIONS FOR USE. Toxic to certain beneficial insects. Minimize spray drift to reduce harmful effects on beneficial insects in habitats next to the application site such as hedgerows and woodland. 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. This product contains aromatic petroleum distillates that are toxic to aquatic organisms. The use of this chemical may result in contamination of groundwater particularly in areas where soils are permeable (for example, sandy soil) and/or the depth to the water table is shallow.
Follow all other precautions, restrictions, and directions for use on the SELECT® Herbicide label carefully.
