Bin clean out: Malathion reminder

July 20, 2016 - Issue 18

This is the season for pre-harvest bin prep. Remember, malathion CANNOT be used to treat bins where canola will be stored or to treat canola as it goes into 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.

When prepping bins, also…
—Make sure storage bins are free of treated seed (which contains pesticides) and animal protein like blood meal and bone meal.
—Clean bins thoroughly prior to storing canola.
—Keep canola cool and dry to avoid spoilage and insect issues.
