FAQ

A: Insect growth regulators are active ingredients that disrupt the insect’s life cycle by interrupting pupal development as opposed to affecting the nervous system through direct toxicity. 

A: Use either a tank mix of Diacon^® IGR PLUS and PBO-8^® Synergist, or a tank mix of Diacon^® IGR, Centynal^™ EC Insecticide, and PBO-8^® Synergist on incoming grain if pyrethroid resistance is suspected in the weevil population.

A: Clean bins thoroughly and apply treatment of Diacon^® IGR PLUS  to walls, floors and surfaces.

A: For the best results, treat in the grain stream as well as the empty bin. By not treating the entire mass, there is a possibility of infestation in the untreated areas of the grain mass.

A: For long-term protection, add Diacon^® IGR PLUS or a tank mix of Diacon^® IGR and Centynal^™ EC Insecticide to the grain as it moves into storage. If weevils are present, add PBO-8^® Synergist to your tank mix.

A: If the infested grain is already in storage, fumigate with an EPA-registered fumigant to eliminate the infestation. Following fumigation, if possible, turn the grain and treat with Diacon^® IGR PLUS or a tank-mix combination of Diacon^® IGR and Centynal^™ EC Insecticide. The best way to prevent an infestation is to treat the commodity in the grain stream as it is being placed into the storage facility.

A: The active ingredient in Diacon^®-D IGR is the insect growth regulator (S)-methoprene. 

A: Add Diacon^®-D IGR to the grain stream as it moves into storage.

A: Diacon^®-D IGR is a dry formulation that can be applied to the moving grain stream by using a scoop or other calibrated device. An automated delivery system, such as one available from Cyclone Mfg. Company, may be used for Diacon^®-D IGR dispensing.

A: Grain can be used immediately after treatment with a tank mix of Diacon^® IGR and Centynal^™ EC Insecticide.

A: For domestic use, there are no exceptions where grain can be shipped or processed when treated according to the label. When tank mixing, the more stringent label must be followed.

A: For export of treated grains, CODEX tolerances and/or country tolerances must be followed. Refer to the specific country of import to determine acceptable tolerances for both (S)-methoprene and deltamethrin prior to treating the commodity.

A: For a cost of approximately 4.5 cents per bushel, you can get one of the best tank mixes in the market for fighting stored product insect infestations.

A: Find the distributor/dealer in your area under the Distribution section of the website.

A: Diacon^® IGR PLUS is an emulsifiable concentrate grain protectant that contains both an insect growth regulator and an adulticide. It is registered by the Environmental Protection Agency for the control of immature insects and adults in stored grains and other agricultural commodities.

A: The active ingredients in Diacon^® IGR PLUS are the IGR (S)-methoprene and the adulticide deltamethrin.

A: Diacon^® IGR contains only an insect growth regulator for the control of insects in the pupal stage to break the life cycle. Diacon^® IGR PLUS is a combination of an insect growth regulator and an adulticide and can be used to control both immature and adult stages of insects.

A: Apply Diacon^® IGR PLUS to the moving grain stream as a coarse spray to provide a concentration of 0.5 ppm – 1 ppm of deltamethrin and 1.25 ppm or 2.5 ppm of (S)-methoprene on the grain. Final spray volume with water solutions is 3-5 gallons of liquid per 1,000 bushels of grain. For rough rice, use 10 gallons of water per 1,000 bushels. For more information, consult the product label.

A: While residual action can vary with conditions and application rates, Diacon^® IGR PLUS can help protect grains over a year at the higher application rates.
