ABSTRACT:
This invention pertains to compositions comprising herbicidal phosphosulfonates, having the general formula ##STR1## wherein Y is an optionally substituted phenyl, naphthyl, benzyl, a (C.sub.5 -C.sub.8)cycloalkyl, a 5-membered heteroaromatic ring, a 6-membered heteraromatic ring, a fused 5,6-membered heteroaromatic ring, or a fused 6,6-membered heteroaromatic ring;
X is an oxygen or a sulfur atom; and
R.sup.1 and R.sup.2 are each independently selected from substituted or unsubstituted alkyl, alkoxy, alkylthio, alkenyloxy, alkynyloxy, haloalkoxy, cyanoalkoxy, alkoxyalkoxy, cycloalkyloxy, cycloalkylalkoxy, alkylideneiminooxy, chloro, amino, phenyl or phenoxy; or R.sup.1 and R.sup.2 are both alkoxy, taken together with the phosphorus atom to form a 6-membered oxygen-containing ring; and
dichloroacetamide safeners having the general formula ##STR2## wherein R.sup.a and R.sup.b are each independently selected from alkyl, alkenyl, or alkyl or alkenyl substituted with halo, or R.sup.a and R.sup.b together with the nitrogen atom to which they are attached form a 5- or 6-membered substituted heterocyclic ring;
and the use of these compositions as selective herbicides.
