Return to Canola Council Home
As bins are prepared for the coming harvest, keep in mind that using malathion on canola seed or in canola storage bins will result in detectable levels of malathion residue because malathion has a strong attraction to the oil in canola seed. Consequently, 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 to store canola.
