Regulatory Status: Butylate is classified by the U.S. Environmental Protection Agency as a General Use Pesticide (GUP), with applications limited to corn fields. It is categorized toxicity class III - slightly toxic. Products containing butylate bear the Signal Word CAUTION.

Chemical Class: thiocarbamate

Introduction: Butylate is an herbicide and a member of the thiocarbamate class of chemicals. It is registered only for use in corn to control grassy weeds such as nutgrass and millet grass, as well as some broadleaf weeds. It is applied to soil immediately before corn is planted, often in combination with atrazine and/or cyanazine. Butylate acts selectively on seeds of weeds that are in the germination stage of development. It is absorbed from the soil by shoots of grass seedlings before they emerge, causing shoot growth to be slowed, and leaves to become twisted.
