S-Ethyl dipropylthiocarbamate (EPTC) is a selective herbicide used for pre-emergent control of certain grasses and broadleaf weeds in Australia and the United States.[3][4] It was introduced in 1957.[5]

EPTC can be applied pre-emergently or post-emergently and its effectiveness does not depend on post-application rainfall. The herbicide takes effect quickly after application. It is registered in every US state.[6] It should be sprayed when the soil is well worked and dry, to allow good mixing and incorporation. It can be stored at temperatures as low as -50 °F.[7]

It is not persistent in soil, having a half-life of about 6 days.[1]

Use

EPTC is applied at rates of 2 to 7.5 lbs/ac in the US, or 2.5-5 kg/ha in Australia, measured by active ingredient. It is typically sold as an emulsifiable concentrate, of 70% of more s-ethyl dipropylthiocarbamate,[8][9] or as granules.[5]

In the United States, EPTC is registered for use on alfalfa, almonds, beans, birdsfoot trefoil, clovers, lespedeza, sainfoin, citrus nursery stock and plantings, cotton, grass, fallow, pine seedlings, potatoes, safflower, sugar beets, sunflower, tomatoes and walnuts.[8]

In Australia, EPTC is used on beans, potatoes, maize, sweet corn, safflower, rapeseed, sunflower, lucerne, duboisia, lotus, non-crop situations and grass.[9]

It has been sold under the tradenames Eradicane, Eptam, Genep and Shortstop. The long-running "Eptam" trademark is of the Stauffer Chemical Company.[7]
