Integrated Pest Management Options

The key to controlling stored-grain insects is prevention through good sanitation and storage practices. See OMAFRA Publication 811, Agronomy Guide for Field Crops, for more information on stored grain insect management.

Comments
Can be applied to dry containers where grain is transported or stored. The structure must remain empty for 1-2 weeks. For maximum effectiveness, the relative humidity must remain below 55% and the temperature above 15°C (59°F). See label for spot and crack treatment rates. For wheat grain treatment, 100 g/tonne of wheat can be used to control rusty grain beetle. Dust may be applied to grain as it enters the auger or conveyor feeder system during grain transfer into the storage facility.

Fumigant

Comments
Must be applied by a professional licensed applicator. Do not fumigate below 5°C (40°F). Exposure to moist air or liquids releases flamable and toxic phosphine gas. Ensure bin is tightly sealed. Not to be used for vacuum fumigations. See label for minimum length of pest exposure periods at various temperatures.
