Grain insects are difficult to find by conventional
methods and many times infested grain enters the elevator undetected. With
infested grain in silos and infested residues in or under conveyors,
equipment and many other locations, there are many opportunities for
insects to access grain that would otherwise remain free from
Protect-It®stored grain insecticide can help reduce
insect problems in the elevator. Protect-It® can be used by
elevator personnel (no licensing necessary) as both a structural and
stored grain insecticide.
should be given to treating empty silos and areas in the elevator, which
can harbor residual populations of insects. As the silos become
empty use the aeration fan or compressed blower to apply
Protect-It® (dry) to the entire bin at 0.6lbs/1000 ft2). It is best to wait several days for Protect-It® to eradicate
all the insects. There is no need to enter the silo and application will
take less than 2 minutes. For a cylindrical silo the amount Protect-It® required
x silo radius (ft) x height (ft)=lbs Protect-It® .
Protect-It® is also ideal for areas in the elevator which can harbor insects.
Using a small nozzle duster fill cracks, crevices and smaller voids with Protect-It® to avoid
reoccurring infestation. For general application to surfaces after
cleaning, use a dust blower (e.g., Hedley's compressed air applicator) to
apply Protect-It® at a rate of 0.6lbs/1000 ft2 ).
Stored Grain (silos and metal
A (for long-term protection from weevils, flour beetles, grain beetles
and Indian meal moth)
Treat the entire grain mass at the following rates:
After grain treatment blow or
sprinkle Protect-It® over the surface of the grain at
the rate of 20lbs/1000 ft2. To calculate the surface treatment
amount, square the radius of the bin and multiply by 3.14. Using a bin
with a 10-foot radius:
Square feet = (10)2 x
3.14 = 314 .
square footage, divide by 1000 and multiply by the rate of 20 lbs/1000
314/1000 x 20 = 6.28 lbs
For a peaked pile, add 30% to this
6.28 + 30% = 8.16 lbs required .
B (for short to
medium term protection from weevils, flour beetles, grain beetles and
Indian meal moth)
research has shown that more than 90% of insects in a concrete silo tend
to inhabit the bottom portion of the grain mass. Before filling the silo,
blow or sprinkle in one 15 lb case of Protect-It® so that it covers the bottom of the
silo (cone). As the silo is filled the force of the falling grain will
disperse Protect-It® throughout the
bottom several feet of the grain mass.
the silo has been filled blow or sprinkle Protect-It® over the surface at the rate of 20lbs/1000 ft2.
silos equipped with aeration, use the fan to blow some Protect-It® into the
aeration system to prevent insect entry into the grain mass.
Stored Grain (metal
C (for short to medium term protection from weevils,
flour beetles, grain beetles)
At the rates indicated below, treat
only the top 3 feet of the grain in the bin.
||24.0 lbs/1000 bu
||19.2 lbs/1000 bu
||12.8 lbs/1000 bu
||22.5 lbs/1000 bu
After treating the top 3 feet, blow Protect-It® over the
surface of the grain mass at the rate of 3 lbs/1000 ft2. For taller bins (18 feet or higher), treat
the bottom 3-feet as well. As an alternative to bottom layer treatment
blow some Protect-It® into the aeration system to
prevent insect entry into the grain mass.
To calculate the number of bushels in a 3-foot layer,
square the radius of the bin and multiply by 7.57.
example, for a bin with a 10 foot radius (radius is ½ bin
= (10)2 x 7.57 = 100 x 7.57 = 757 .
treat one 3-foot layer of wheat you need:
x 24.0 = 18.17 lbs
flat storage, treat the empty storage before filling at the rate of 0.6 lbs/1000 ft2. After filling blow Protect-It® over the surface of the grain mass at the rate of 20 lbs/1000 ft2. To calculate
surface area, take the floor area and add 30% for grain in a peaked
