Phenoxybenzonitriles, halo-substituted on the phenoxy ring and halo- or alkyl-substituted on the benzonitrile ring ortho to the para-cyano position, form a new class of herbicides. These substituted phenoxybenzonitriles and herbicidal compositions containing them are highly effective as pre-emergence and post-emergence herbicides, especially at low use concentrations. They are highly effective against Crabgrass, Yellow Foxtail grass and Barnyard grass, annual grass weeds which reproduce by seed. They are also highly effective against Johnson grass, a perennial grass weed which reproduces by seed and underground rhizomes, and Pigweed, an annular broadleaf weed which reproduces by seed.
苯氧基苯甲腈,苯氧环上取代卤素,苯甲腈环上邻位对位于对氰基位置的卤素或烷基取代物,形成一类新型除草剂。这些取代的苯氧基苯甲腈和含有它们的除草剂组合物在低浓度下作为除草剂,尤其是在前期和后期除草方面具有高效性。它们对蟹草、黄狗尾草和谷子草等以种子繁殖的一年生草本杂草有很高的除草效果。它们也对以种子和地下根茎繁殖的多年生草本杂草约翰逊草和以种子繁殖的圆形叶宽叶杂草猎豚草有很高的除草效果。
