Undesired vegetation such as crabgrass, downey brome, giant foxtail, yellow foxtail, barnyard grass, flax and wild oats are combated by pre-emergent application of at least one compound belonging to a class of substituted N-benzyl amides of alkanoic and benzoic acids, particularly in the presence of seeds of such crops as cotton and soybeans. Illustrative of compounds which are very effective against several species of grasses as well as some broadleaf weeds in the presence of soybeans and cotton are two with the following structural formulas: ##EQU1## and ##EQU2##
不受欢迎的植被,如蟹草、细叶雀麦、巨大的狗尾草、黄狗尾草、谷子草、亚麻和野燕麦,通过预发生施用至少一种属于取代N-苯甲酰胺和脂肪酸、苯甲酸类化合物的类别的方法来对抗,尤其是在棉花和大豆等作物的种子存在的情况下。对几种草类和一些阔叶杂草在大豆和棉花存在的情况下非常有效的化合物包括以下两种具有以下结构式的化合物:##EQU1## 和 ##EQU2##
