The Canola Council of Canada is reminding growers of the importance of planning canola storage requirements carefully, especially where the use of malathion is being considered.To avoid unacceptable residues that jeopardize crop marketability, growers should make sure to keep canola out of bins that have been treated with malathion for a minimum of six months since the last bin treatment.
If growers are using malathion to treat cereals and other non-oilseed grains in bins that have been contaminated with insects, they should record the date of treatment to ensure canola is not stored in that bin until at least six months have passed.
As well, malathion must never be used to prepare canola for storage.
Canola found with malathion residues is unacceptable for export customers and can damage Canada’s reputation as a trusted supplier. The Canola Council of Canada recommends growers follow these procedures to properly store canola, or cereal crops in bins intended for future storage of canola:
- Clean bins thoroughly, making sure they are free of treated seed and animal protein.
- If insect treatment is necessary, only use approved products. Malathion must never be used to prepare canola for storage or to treat grain bins that will store canola.
- Condition crops to moisture and temperature levels suitable for long-term storage. Be sure to check the condition of storage bins regularly. Visit this page for more information about keeping canola bins malathion-free.
