Chances are you are among many producers who
take the time to clean out their grain bins before harvest.
Although not a particularly exciting or comfortable
job, it is well worth the effort to prepare your
bins for your new crop storage. Old crop is the primary
source of grain infestation for new crop going
into storage. Even a handful of grain residue is
enough to harbour hundreds of insects. When new
grain is stored, insects can easily migrate into new
grain from old grain residues in grain bins, aeration
systems or from the outside in piles of rotting grain.
An important key to keeping insects out of your grain
is to adequately prepare your grain bins by cleaning
and then applying Protect-It® before harvest. Cleaning
grain bins involves sweeping, and if possible, vacuuming
grain residues lodged in cracks and crevices
around floor perimeters and on top of structural supports.
Sweepings should be burned or buried.
After cleaning, apply Protect-It® to control any insects
that remain in the bin. Protect-It® can be applied
from outside the bin using the aeration fan or dust
blower (call Hedley for details). The advantage of this
is that the dust covers all surfaces in the bin from
the ceiling to floor, including under the plenum forUnlike most insecticides, Protect-ItŪ remains effective
for as long as it is present in your empty bin. This
allows for advance application at your convenience,
without risk of re-i nfestation.
Empty Bin Application:
Dry – use aeration fan or hand blower to get the
Protect-It® powder into the empty bins. Cover inside
surface area of bin at a rate of just under 500 grams
per 1,000ft2 (5g/m2).
Spray – Mix 1.5kg (1,500 grams) of Protect-It® into 10
litres of water. Spray inside surface area at a rate just
under 5L per 1,000ft2 (50mL/m2).
Sample application rates for empty bin
