摘要： Compositions containing an .alpha.-chloroacetanilide compound of the formula ##SPC1##Wherein R.sup.1 is selected from the group consisting of primary and secondary alkyl radicals of 1-3 carbon atoms and R.sup.2 is selected from the group consisting of hydrogen and primary and secondary alkyl radicals of 2-3 carbon atoms, are useful for protecting various agronomic crops from undesirable weed infestation. Presently preferred because of their optimum selective herbicidal activity are those compounds wherein R.sup.1 of the above structure is either methyl or ethyl and R.sup.2 is ethyl.
