Select herbicide label expanded for rutabaga, green onions and leeks

The Select herbicide label has been expanded via the Minor Use Program to help manage labelled weeds on rutagaba, green onions and leeks. 


The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for Select herbicide for control of labelled weeds 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) (Green Onion, Leek) and the Ministère de l'Agriculture, des Pêcheries et de l'Alimentation (MAPAQ) (Rutabaga) 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 disease management decisions within a robust integrated weed management program and should consult the complete label before using Select herbicide.

This product is toxic  to aquatic organisms and non-target terrestrial plants. Observe buffer zones specified 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.
