| Insecticide and formulation | Application Type | Stored commodity | Rate of formulation per 2.5 gallons of water (treats 1250 sq ft of surface) | Remarks |
|---|---|---|---|---|
| Bacillus thuringiensis (Bt) (Biobit, Dipel, etc.) |
Liquids | Grains, soybean | See label for rates | No activity against weevils. |
| Chloropyrifos-methyl and cyfluthrin (Storcide) |
Liquids | Wheat, barley, oats, and sorghum (milo) | See label for rates which vary with the grain crop | Dilute label rate in 5 gal of water. Dilute with water of FDA approved food grade mineral or soybean oil. Cyfluthrin, a component in Storcide does not have CODEX MRLs. Check with your grain handling before exporting. |
| Chlorpyrifos-methyl (Reldan 4E) |
Liquids | Barley, oats, rice, grain sorghum, and wheat | See label for rates which vary with the grain crop | Reldan is not labeled for corn. Reldan does not have activity on lesser grain borer and has limited activity on existing populations of insects. NOTE: Reldan 4E will be sold by Gustafson until 12/31/04 to authorized distributors; distributors can sell until 12/31/05, and treated grain will be given the opportunity to move through grain channels until 2009-2010. |
| Diatomaceous earth (DE) (Insecto) |
Dusts | Stored grain, barley, corn, oats, rice, grain sorghum, soybeans, and wheat | Rate depends on product and formulation (see product label) | Treat the first loads in the bottom of the bin and the last loads in the top of the bin. Product can be irritating to workers and abrasive to equipment. Reduction in test weights are possible, but can be limited when used as a topdress treatment. |
| Pirimiphos-methyl (Actellic 5E) |
Liquids | Corn and grain sorghum (milo) only | 9.2-12.3 oz in 5.0 gal of water/ 30 tons (~1071 bu) of grain | One (1) treatment per load of grain only. Actellic is effective against Indian meal moth at the highest rate and suppresses lesser grain borer. Do not apply before high temperature drying is completed. Extreme heat results in volatilization and reduction in residual control. |
