CGC advises aerating grain to prevent insect infestations

WINNIPEG, October 9, 2009 – Across the Prairies, September was warmer than most of the summer. During the 2009 harvest, some producers reported storing their grain at temperatures close to 30°C.  Producers who stored their grain while outdoor temperatures were high can keep their crops in good condition this fall by following advice from the Canadian Grain Commission.

To help prevent insect infestations, the Canadian Grain Commission’s stored products entomologist, Blaine Timlick, cautions producers to check the temperature of their stored grain. He recommends producers aerate their grain to bring the temperature to below 15°C as quickly as possible.

Suction aeration, which pulls air from the top of the bin to the bottom, is a better method of aerating than traditional methods that push air through the grain mass. Suction aeration allows for better insect control as it cools grain faster. If producers do not have aeration systems, they should turn their grain frequently and monitor its temperature. Producers can go online to learn more about aerations systems through resources available on the Internet.

The Canadian Grain Commission reminds producers that elevator managers have the right to refuse any deliveries they suspect are infested. Depending on how grain is stored, it can be more susceptible to insect infestation. The Canadian Grain Commission’s web site (www.grainscanada.gc.ca) offers more tips for preventing insect infestation during fall grain storage.

While reducing temperature through aeration helps producers manage insect pests, producers should also consider keeping grain at a low, uniform temperature to avoid the development of moulds and associated mycotoxins. The key to avoiding damage and potential loss is managing the overall quality of grain.

The Canadian Grain Commission is the federal agency responsible for establishing and maintaining Canada’s grain quality standards. Its programs result in shipments of grain that consistently meet contract specifications for quality, safety and quantity. The Canadian Grain Commission regulates the grain industry to protect producers’ rights and ensure the integrity of grain transactions.
