HERBICIDAL METHOD UTILIZING PHOSPHOSULFONATE HERBICIDES AND OXIME ETHER SAFENERS

摘要

ABSTRACTThis invention pertains to a method for selectively controlling weedscomprising(i) applying to the desired crop seed a quantity of an oxime ether safener havingthe general formula(I)whereinA is a hydrogen atom or a halogen atom;Q is cyano orZ is a halogen atom, cyano, haloalkyl, haloalkoxy or nitro;n is 2 or 3;(ii) planting the treated seed;(iii) applying a composition comprising one or more phosphosulfonate herbicideshaving the general formula (II)whereinY is an optionally substituted phenyl, naphthyl, benzyl, a (C5-C8)cycloalkyl, a5-membered heteroaromatic ring, a 6-membered heteraromatic ring, a fused5,6-membered heteroaromatic ring, or a fused 6,6-membered heteroaromatic ring;X is an oxygen or a sulfur atom; andR1 and R2 are each independently selected from substituted or unsubstitutedalkyl, alkoxy, alkylthio, alkenyloxy, alkynyloxy, haloalkoxy, cyanoalkoxy,alkoxyalkoxy, cycloalkoxy, cycloalkylalkoxy, alkylideneiminooxy, chloro, amino,phenyl or phenoxy; or R1 and R2 are both alkoxy, taken together with thephosphorus atom to form a 6-membered oxygen-containing ring;and an agronomically acceptable carrier.
