Product Overview
Diacon® IGR Liquid Grain Protectant is a professional stored commodity insect growth regulator used to help protect stored grains, seeds, feeds, spices, and other labeled commodities from stored product insects. Powered by (S)-methoprene, Diacon® IGR disrupts insect development by preventing larvae from developing into reproducing adults.
Unlike a traditional adulticide, Diacon® IGR is designed for long-term population management by interrupting the stored product insect life cycle. It is commonly used in grain elevators, farm storage, feed mills, seed storage, food processing facilities, warehouses, silos, and other stored commodity environments.
