Producers are urged to keep malathion far away from canola seed.
Growers should not use the insecticide to treat canola in storage bins, nor should canola be stored in bins that have been treated with malathion in the past six months.
Using malathion to treat canola for storage or in empty bins where canola will be stored will result in residues in the seed. Any residues detected in canola that is exported to Japan could cost the industry millions of dollars in lost business.
To prevent insect problems in stored canola, make sure the bins are free of chaff, seeds and foreign material. Combine settings should be set to harvest sound seed.
Bins must be well sealed to prevent moisture infiltration and should be insecticide-free.
It is important to keep canola cool and dry in the bin. For long-term storage, temperatures should be kept at less than 15 C and grain moisture levels below eight percent.
