Dust generated during the planting of neonicotinoid treated corn and soybean seed may be harmful to honeybees and other pollinators. The requirement is to use a dust-reducing fluency agent to help reduce seed dust during planting.
When using a seed flow lubricant for planting corn and soybean seed treated with neonicotinoid insecticides (containing the active ingredients clothianidin, imidacloprid and thiamethoxam):
- Use only a dust-reducing fluency agent.
- Talc and graphite are not permitted.
- Planting machinery that does not currently require the use of a seed flow lubricant.
- The use of graphite may continue as a mechanical lubricant in finger pickup or mechanical type planters only (in other words, non-pneumatic equipment).
Use of dust-reducing fluency agents
- Carefully follow the use directions on the dust-reducing fluency agent label.
Help protect bees and other pollinators
- Follow all label instructions - both on the pesticide label and the fluency agent label.
- Do not load or clean planting equipment near bee colonies, and avoid places where bees may be foraging, such as flowering crops or weeds.
- When turning on planting equipment, avoid engaging system where emitted dust may contact honeybee colonies.
- Spilled or exposed seeds and dust must be incorporated into the soil or cleaned up from the soil surface
- Refer to the complete guidance Protecting pollinators when using treated seed - best management practices on the Health Canada's pollinator protection web page on Canada.ca.
- Report bee mortality incidents suspected to be related to pesticide exposure.
