WINNIPEG, Sept. 18, 2014 /CNW/ - Large amounts of last year's grain are
still in storage and this year's grain is beginning to be delivered
into the handling system. How you can protect all of your grain from
spoiling or becoming infested?
The Canadian Grain Commission has tips to help you manage the quality of
grain already in storage. We also have steps you can take before you
start filling your bins to keep your stored grain in good condition.
To protect the quality of grain currently in storage, the Canadian Grain
Commission recommends you:
Sample the grain from the core at a depth of 30 to 50 cm (12 to 18
inches) from the surface. Insects are likely to be found in pockets of
warm or moist grain. Sieve the samples or examine small portions
carefully. Typically, stored product insects are very small beetles
(less than 3 mm or 1/8 inch) that may not be moving. A magnifying glass
can be helpful.
Monitor your grain in storage, if you can. Try to establish the
temperature and moisture content of your grain as this will help you
make decisions before insect or mould problems begin. For best results,
your grain's temperature should be less than 15°C. As well, you should
keep your grain at the appropriate moisture content, depending on its
type (for example, wheat should be at or lower than14.5% moisture
content). Grain temperature and moisture content should be as uniform
If you find insects, identifying them will help you decide what to do.
The Canadian Grain Commission has insect identification keys online
that can help you. If you cannot identify an insect using these keys,
call our Infestation Control and Sanitation Officer.
Insects in your grain could be grain feeders, fungal feeders, or
predators of these insects. By accurately identifying insects, you can
determine the appropriate control method.
The Canadian Grain Commission's web site has advice on controlling grain
feeding insects. You can also contact our Infestation Control and
Sanitation Officer for further assistance.
Before harvest, insects may be attracted by grain residue around bins
and storage areas. Before harvest, the Canadian Grain Commission
Make sure storage areas are clean and free from grain residues that can
harbour or attract insects.
If required, treat your empty storage bins with a registered contact
insecticide such as malathion, pyrethrin or a diatomaceous earth-based
product. Make sure you treat floor-wall joints, aeration plenums or
floors and access points thoroughly. Note: Do not use malathion in bins
intended for canola storage.

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.
