Prevent insect infestations when storing grain
WINNIPEG, Sept. 6, 2013 /CNW/ – As the 2013 grain harvest gets under way
it is important for grain producers to take steps now to reduce
potential insect infestations in stored grain, according to the
Canadian Grain Commission.
“Although this year was not as warm as the preceding summer, there is
ample potential for stored grain insects to infest bins as grain comes
in from harvest,” explains Brent Elliott, Infestation Control and
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 bin 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 tough and damp ranges for cereal grains are:
___________________________________________________________________ |Grain | Tough (%)| Damp (%)| |_____________________________________________|___________|_________| |Wheat, all classes |14.6 - 17.0|Over 17.0| |_____________________________________________|___________|_________| |Oats |13.6 - 17.0|Over 17.0| |_____________________________________________|___________|_________| |Barley - malting |13.6 - 17.0|Over 17.0| |_____________________________________________|___________|_________| |Barley - food, covered |13.6 - 17.0|Over 17.0| |_____________________________________________|___________|_________| |Barley - food, hulless |14.1 - 17.0|Over 17.0| |_____________________________________________|___________|_________| |Barley - general purpose, covered and hulless|14.9 - 17.0|Over 17.0| |_____________________________________________|___________|_________|
Producers should also:
-- 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 and moisture content to recommended level as quickly as possible. -- Keep the temperature of grain low and uniform, below 15ºC. -- While daytime temperatures remain high, run fans only at night. -- When air temperature is cooler than grain, run fans 24 hours to cool and dry grain. -- 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.
