Remember to Avoid Malathion in Storage

Canola should not be stored in bins that were previously treated with malathion since canola oil has a strong attraction to the insecticide and will result in detectable residues. Malathion can move into canola seed from storage bin walls. Detection of malathion residue in canola seed above the allowable limit will result in rejected shipments and increased monitoring.  Do NOT use malathion to treat bins destined for canola. If a bin has been treated with malathion, it should not be used to store canola for at least six months after treatment. More information is available at the following link:
