Method for controlling the growth of weeds in a field containing growing plants of cotton

摘要

Alkyl N-3-carbamoyloxyphenyl-carbamates of the formula ##STR1## selectively damage or destroy weeds in crops of carrots, cotton, peanuts, and rice without damaging the crop plants when R.sub.1 is lower alkyl, allyl, or halo-lower-alkyl; R.sub.2 is lower alkyl, allyl, halo- lower alkyl, lower alkinyl, cyclohexyl, benzyl, or phenylethyl; R.sub.3 is methyl and ethyl; and X is oxygen or sulfur. Lower alkyl and lower alkinyl in the formula have up to four carbon atoms.
