Trade and Other Names: Trade names for bensulide include Betamec, Betasan, Bensumec, Benzulfide, Disan, Exporsan, Prefar, Pre-San, and R-4461. It is used in combination with other pesticides such as thiobencarb and molinate.

Regulatory Status: Bensulide is classified as a General Use Pesticide (GUP) by the U.S. Environmental Protection Agency. It is classified toxicity class III - slightly toxic. Products with bensulide bear the Signal Word CAUTION.

Chemical Class: organophosphate

Introduction: Bensulide is a selective organophosphate herbicide. It is one of a few organophosphate compounds that are used as a herbicide. Most of the others are used as insecticides. It is used on vegetable crops such as carrots, cucumbers, peppers, and melons and in cotton and turfgrass to control annual grasses such as bluegrass and crabgrass and broadleaf weeds. It is often applied before the weed seeds germinate (pre-emergence) in order to prevent them from germinating. It is available as granules or an emulsifiable concentrate. Estimates place the total U.S. use of bensulide at about 632,000 pounds annually. Application rates may be relatively heavy (up to 22.6 kg/ha) when it is used.

Formulation: It is available as granules or an emulsifiable concentrate.
