Abstract
Chloroacetanilides are disclosed having the general formula: ##STR1## wherein R.sup.1 =H, or alkyl with 1-5 carbon atoms, or X; PA1 X=alkenyl, and preferably ##STR2## in which the various R.sup.2, which may be equal to or different from each other, are H or an alkyl with 1-3 carbon atoms; PA1 A=alkylene, optionally substituted, of the formula: ##STR3## in which the various R.sup.2, which may be equal to or different from each other, have the meanings specified above; and PA1 Y=H; alkyl with 1-5 carbon atoms; alkenyl with 2-5 carbon atoms; alkinyl with 2-5 carbon atoms; phenyl; cycloalkyl with 3-8 carbon atoms; halogen; ##STR4## wherein R=H; alkyl with 1-5 carbon atoms; alkenyl or alkinyl with 2-5 carbon atoms; cycloalkyl with 3-8 carbon atoms; phenyl; The chloroacetanilide derivatives are useful in combatting infestations of infesting monocotyledons and dicotyledons during pre-emergence, by spreading the chloroacetanilide derivative on the soil adjacent thereto in quantities ranging from 0.25 kg/ha upwards.
