Documented Uses

• Used as a selective pre-planting herbicide; [Merck Index]
• A thiocarbamate compound used as a selective preplant incorporated herbicide. Because of its volatility, it must be incorporated immediately after application. Controls most grassy weeds, including nutgrass, in corn. Do not apply on milo or sorghum.
• A selective herbicide ... well tolerated by corn. ... Effective against annual grass weed species such as barnyard grass ... crabgrass ... foxtails ... and goosegrass ... it is also effective against nutsedges ... bermudagrass seedlings ... and johnsongrass seedlings ... .
• Butylate is made by the reaction of di-isobutylamine with phosgene to give the carbamoyl chloride which is reacted with ethanethiol to give butylate.
• Preparation: ... H. Tilles, J. Antognini, United States of America patent 2913327 (1959 to Stauffer)
• Between 6 and 15 million lbs of butylate are applied annually to crops in the United States.
