Keep malathion out of canola bins

Malathion CANNOT be used to treat bins where canola will be stored or to treat canola as it goes in to storage. These applications can result in residues in the canola that are unacceptable in some of Canada’s key export countries with low minimum residue limits (MRLs) or zero tolerance for malathion. If a bin was treated previously, do not store canola in the bins within six months of treatment. Detection of malathion residue in canola seed above the allowable limit will result in rejected shipments and increased monitoring.
