Protect your stored grain from insects and treat your empty bins with ...   ALWAYS READ AND FOLLOW LABEL DIRECTIONS On-Farm Application of Protect-It® Protect-It® is a structural and stored grain insecticide powder created exclusively for use in and around stored grains and seeds. Protect-It® is made entirely of naturally occuring diatomaceous earth (Figure 1) and synthetic silica gel. These materials stick to the insect (Figure 2) causing it to lose water and die. Because of its low application rates, this patented combination of materials minimizes effects on grain flow rates and test weight. Figure 1. Diatomaceous Earth (DE) 900X magnification Figure 2. DE on insect skin 440X magnification   Protect-It® provides the following benefits . . . Exempt from residue tolerance limits and doesn't leave toxic residues No applicator certification required Controls most stored grain insect pests, including rusty grain beetles, weevils, flourbeetles,  Indian meal moth Very long-lasting-will not degrade so long as treated grain is in storage Will not affect germination, milling, baking or malting quality Can be used in and around animal feeds No re-entry delay after application of Protect-It® Odorless Proven technology Registered for use on most common grains and seeds For the protection of farm-stored grain, follow ALL 3 steps (below): Step One Empty Bin Treatment: 1-2 weeks before harvest clean your empty bins and apply Protect-It® at the rate of 5g/square meter (454g/1000 square feet) to all interior surfaces. Apply Protect-It® to the empty bin using either your aeration fan (Figure 3) or a dust blower (Figure 4). Calculation To begin, find out the diameter (ft) of the bin and the height of the bin to the eaves.For this calculation you need to determine the radius of the bin, which is 1/2 the diameter.     A. Floor area = Radius x Radius x 3.14     B. Ceiling = take floor area and add 30% (for peaked roof)     C. Wall area = Radius x Height to eaves x 6.29       Add areas of floor, ceiling and walls to determine total area.     First divide total area by 1000 and then multiply this number by 0.454 to     dertermine the amount of Protect-It (kg) required to treat the empty bin. Figure 3. Aeration fan application Figure 4. Compressed air duster Step Two Grain mass application: Apply Protect-It® to uninfested grain immediately at harvest as grain is being augered into the bin. (Do not store new crop on top of old crop.) After calclating the amount of Protect-It® required, apply to grain directly at the auger (Figure 5) or use the truck method as follows: After calculating the required amount of Protect-It® required to treat the entire truckload of grain, take half of this amount and spread as evenly as possible over the entire surface of the grain in the truck (see Figure 6) After the truck is about half empty, evenly spread the remaining Protect-It® over the surface of the grain remaining in the truck (see Figure 7). See the label for application rates.

For example, for a 10 metric ton truck load of wheat, at the rate for wheat of 100 grams per metric ton, you would apply 1000 grams or 1.0kg. Every 250ml cup of Protect-It®  weighs about 50g, so for this truckload about 20 cups or 5 litres of Protect-It® are required.

Step Three

Surface Dressing: Blow or sprinkle Protect-It® over the surface of the grain mass in the bin at the rate of 20g/square meter (1.86 kg/1000 square feet).

Calculation

Take ceiling area (see calculations for Step One) and divide this by 1000. Multiply this number by 1.86 to give the amount (kg) of Protect-It® for surface dressing.
