The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for SERENE® Herbicide for control or suppression of labelled weeds in various crops and crop groups in Canada. SERENE® Herbicide was already labeled for management of weeds in other crops in Canada. These minor use proposals were submitted by The Ontario Ministry of Agriculture, Food, and Rural Affairs 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 SERENE® Herbicide.
| Crop / Crop Group | Target | Rate (L product/ha) | Application Information |
| Crop Group 1 (Root and Tuber Vegetables) (including Ginseng) Crop Group 13-07 (Berries and Small Fruits) (greenhouse or field) (including Haskap) Globe Artichokes Peanuts Hops | Suppression or Control of Labelled Weeds | 179 – 717.5 | Apply Serene as a uniform band or spot application directed at weeds on the ground between the crop. Apply using hooded or shielded application equipment. Ensure spray drift will not come in contact with foliage. Do not spray the crop directly. Do not apply when plants are under stress. Retreatment is required for regrowth of weeds. |
| Crop Group 14-11 (Tree Nuts) | Suppression or Control of Labelled Weeds | 179 – 717.5 | Apply Serene as a uniform band or spot application directed at weeds on the ground between the trunks or plants. Ensure spray drift will not come in contact with foliage. Do not spray the crop directly. Apply only to weeds around healthy established trees. Do not apply after budbreak unless using hooded or shielded application equipment and applicator can ensure spray drift will not come into contact with fruit or foliage. Do not apply when plants are under stress. Retreatment is required for regrowth of weeds. * – Apples already labelled with separate use instructions |
Toxic to aquatic organisms and non-target terrestrial plants. Observe buffer zones specified under DIRECTIONS FOR USE. 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.
Follow all other precautions, restrictions, and directions for use on the SERENE® Herbicide label carefully.
