| 摘要 |
This invention pertains to compositions comprising herbicidal phosphosulfonates, having the general formula <IMAGE> (I) wherein Y is an optionally substituted phenyl, naphthyl, benzyl, a (C5-C8)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 R1 and R2 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 R1 and R2 are both alkoxy, taken together with the phosphorus atom to form a 6-membered oxygen-containing ring; and dichloroacetamide safeners having the general formula <IMAGE> (II) wherein Ra and Rb are each independently selected from alkyl, alkenyl, or alkyl or alkenyl substituted with halo, or Ra and Rb 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.
