Note: Allium leafminer has not been detected in Canada. This label expansion was submitted pre-emptively in the event of detection in Canada.
The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for EXIREL® insecticide for control of Allium leaf miner on Allium Bulb Vegetables.
EXIREL® insecticide was already labeled for management of insects on a wide range of crops in Canada. This minor use proposal was 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 insect management decisions within a robust integrated insect management program and should consult the complete label before using EXIREL® insecticide.
| Crop(s) | Target | Rate (mL product / ha) | Application Information | PHI (days) |
| Allium Bulb Vegetables (refer to label for full list) | Control of Allium leaf miner | 100-1500 | Begin applications when treatment thresholds have been reached. Thorough coverage is important to obtain optimum control. Use sufficient water to obtain thorough, uniform coverage. For the pest listed above, use the high rate under heavy pest pressure. Do not make more than 4 applications per season. Do not apply more than once every 5 days. Do not exceed a total of 4.5 litres EXIREL® insecticide per ha per season. Do not make a foliar application of EXIREL® insecticide for a minimum of 60 days following an in-furrow or soil application or planting of seed or seed pieces treated with any Group 28 insecticide. | 1 |
Toxic to non-target terrestrial plants. Observe spray buffer zones specified under DIRECTIONS FOR USE. Toxic to aquatic organisms. Observe spray buffer zones specified under DIRECTIONS FOR USE. 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. Toxic to bees. DO NOT apply this product to blooming crops or weeds while bees are actively visiting the treatment area. Apply early in the morning or late in the evening when bees are not active. Minimize spray drift to reduce harmful effects on bees in habitats close to the application site. 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. As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests. DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes. DO NOT allow effluent or runoff from greenhouses containing this product to enter lakes, streams, ponds or other waters. To further minimize exposure to pollinators, refer to the complete guidance “Protecting Pollinators during Pesticide Spraying – Best Management Practices” on the Health Canada website (www.canada.ca/pollinators).
Follow all other precautions, restrictions, and directions for use on the EXIREL® insecticide label carefully.
