Abstract

A substituted 3-phenyluracil of the formula I ##STR1## where PA1 X.sup.1 and X.sup.2 are each oxygen; PA1 W is --C(R.sup.8)=X.sup.5, where PA1 X.sup.5 is oxygen, sulfur, or a radical --NR.sup.14 ; PA2 R.sup.14 is hydroxyl, alkoxy, alkenyloxy, alkynyloxy, cycloalkoxy, cycloalkenyloxy, haloalkoxy, haloalkenyloxy, hydroxyalkoxy, cyanoalkoxy, cycloalkylalkoxy, alkoxyalkoxy, alkoxyalkenyloxy, alkylcarbonyloxy, haloalkylcarbonyloxy, alkylcarbamoyloxy, haloalkylcarbamoyloxy, alkoxycarbonylalkoxy, alkylthioalkoxy, dialkylaminoalkoxy, PA1 R.sup.8 is hydrogen, cyano or alkyl; PA1 R.sup.1 is halogen or cyano; PA1 R.sup.2 is hydrogen or halogen; PA1 R.sup.3 is hydrogen or alkyl; PA1 R.sup.4 is cyano, alkyl or haloalkyl; PA1 R.sup.5 is hydrogen, halogen or alkyl; or a salt or enol ether of a compound I wherein R.sup.3 is hydrogen, or its tautomeric forms, for the desiccation and defoliation of plants or as an insecticide or herbicide.
