WINNIPEG, July 25, 2012 /CNW/ - A warm summer on the Prairies has
increased the risk of insect infestation in stored grain. Grain
producers can take steps now and prevent insect infestations in stored
grain, according to the Canadian Grain Commission.
"This year we've had a mild winter followed by a warm summer. In these
conditions, insects, such as the rusty grain beetle and the red flour
beetle, can increase in number dramatically," explains Brent Elliott,
Infestation Control and Sanitation Officer at the Canadian Grain
Even before harvest begins, insects may be attracted to bins if there is
enough debris for them to feed on. Producers can prepare their empty
bins for storage by:
Ensuring bins and areas around bins are clean and free of debris
Repairing or sealing any cracks or crevices. Even small amounts of grain
can attract insects.
Treating bins with a registered insecticide
Cleaning and treating aeration plenums and spaces under bins floors
where debris may collect and attract insects.
To maintain overall grain quality and minimize insect pest problems once
grain is in storage, producers should:
Dry grain before storing it, if necessary, to bring it to the
recommended moisture content. The Official Grain Grading Guide's specifications for dry grain are:
Barley (all except select): 14.8% moisture or less
Wheat (all classes) : 14.5% moisture or less
Oats (all) and Barley (select): 13.5% moisture or less
Use aeration to help control the heat and moisture of grain in storage,
particularly if grain is stored at a high temperature.
Bring grain temperature below 15°C as quickly as possible.
Keep the temperature of grain low and uniform, below 15ºC.
If using aeration, keep the surface of the grain inside the bin as level
as possible to avoid the collection of moisture in the cone.
Monitor grain routinely to ensure insects are not becoming a problem.
