Bensulide is an organophosphate acetylcholinesterase inhibitor used as an insecticide. It functions as a nerve agent for many insects. acetylcholinesterase is the main active in ingredient in Bensulide and many other commonly used insecticides. Bensulide is known to be a cancer causing agent to humans.[1] Generally speaking, Bensulide is used for Cole crops, cucurbits, leafy vegetables, legumes, onion, and garlic.[2] The EPA classifies Bensulide as a General Use Pesticide.[3]


Bensulide generally is applied to bare soil, before crops are planted. It is incorporated 1 to 2 inches deep in order for the control of grasses and broadleaf weeds in agricultural crops, residential grass lawns, and golf courses.[1]


Proturk Goosegrass and Crabgrass Control (EPA Reg. No. 00053800164) and Anderson's Goose and Crabgrass Control (EPA Reg. No. 00919800176) both have Bensulide as one of their active incredients, along with oxadiazon at a concentration of 5.25% and 1.31% respectively.[4] Bensulide products may be used outdoors by homeowners on lawns and ornamentals, and by professional lawn care operators. Bensulide may be used on turf (primarily golf course greens and tees), on ornamentals, and for greenhouse and outdoor uses in commercial nurseries. 550,000 pounds of active incredient are used per year, a relatively low value [3]


There are a few minor risks that are involved with herbicides that include Bensulide. Generally, indirect exposure to it is non-lethal. Dietary exposures from eating food crops treated with bensulide are below the level of concern for the entire U.S. population, including infants and children. Drinking water is not a significant source of exposure.[3]

Risks are of concern for homeowners who apply bensulide, and for children entering turf areas treated with bensulide if label directions are not followed properly. EPA also has risk concerns for workers who mix, load, and/or apply bensulide to agricultural sites, golf courses, and home lawns. Chronic risks are of concern for birds and mammals; risks are posed to some aquatic species.[3]
