About us

Prodiamine is an herbicide that works by preventing cells in plants’ roots and shoots from dividing. It is low in toxicity to people. It does not dissolve well in water and binds tightly to soil. It breaks down slowly in soil, but rapidly if exposed to sunlight or if it is in water. Prodiamine is low in toxicity to bees and other beneficial insects but moderately toxic to earthworms. It is toxic to some aquatic animals. The U.S. Environmental Protection Agency (U.S. EPA) considers prodiamine a “possible human carcinogen.”
