The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for LOROX L® Herbicide for control or suppression of labelled weeds in celery in Canada. LOROX L® Herbicide was already labeled for management of weeds on a wide range of crops in Canada. This minor use proposal was submitted by the registrant, Tessenderlo Kerley Inc. (TKI), to reinstate the use following a phase-out originally announced in RVD2020-10 after new supporting information was submitted to PMRA for review.
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 LOROX L® Herbicide.
| Crop(s) | Target | Rate (L product/ha) | Application Information | REI (days) |
| Celery | Suppression or Control of Labelled Weeds | 1.9 – 3.5 | Apply to transplants as soon as new growth has started. Some temporary discolouration may occur. See paragraph on Soil Limitations. Do not apply more than 1 application per year. | Scouting: 10 All Other Tasks: 4 |
Toxic to aquatic organisms and non-target terrestrial plants. Observe spray buffer zones specified under DIRECTIONS FOR USE. Toxic to birds. Toxic to small wild mammals. Toxic to certain beneficial arthropods (which may include predatory and parasitic insects, spiders, and mites). Minimize spray drift to reduce harmful effects on beneficial arthropods 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 filter strip between the treated area and the edge of the water body.
Follow all other precautions, restrictions, and directions for use on the LOROX L® Herbicide label carefully.
