This invention is concerned with a method for destroying undesirable plant life which comprises applying to said plant life a herbicidally toxic amount of a herbicide containing a chemical compound of the formula ##STR1## wherein R is selected from the group consisting of alkyl having 1 to 3 carbon atoms and alkenyl having 2 to 3 carbon atoms; Z is selected from the group consisting of oxygen and sulfur; X is selected from the group consisting of halogen, lower alkyl, lower alkenyl, lower haloalkyl, lower alkoxy, nitro, amino, lower alkylamino, lower dialkylamino, lower acylamino, N-lower alkyl-N-lower acylamino, lower alkylthio, lower alkylsulfoxide, lower alkyl sulfone, cyano, thiocyano and --N.dbd.CHR' wherein R' is selected from the group consisting of hydrogen and lower alkyl; and n is an integer from 0 to 4, provided a maximum of two X's are selected from the group consisting of nitro, amino, lower alkylamino, lower dialkylamino, lower acylamino and N-lower alkyl-N-lower acylamino when n is greater than 2. The term "lower" as used herein means up to about ten carbon atoms.
这项发明涉及一种用于销毁不需要的植物生长的方法,包括向所述植物生长施加含有化学化合物的除草剂,其化学式为 ##STR1## 其中R选自由1至3个碳原子的烷基和2至3个碳原子的烯基组成的群; Z选自由氧和硫组成的群; X选自由卤素、低烷基、低烯基、低卤代烷基、低烷氧基、硝基、氨基、低烷基氨基、低二烷基氨基、低酰氨基、N-低烷基-N-低酰氨基、低烷基硫基、低烷基亚氧化物、低烷基砜、氰基、硫氰基和--N.dbd.CHR',其中R'选自由氢和低烷基; n为0至4的整数,当n大于2时,所选的X中最多有两个来自于硝基、氨基、低烷基氨基、低二烷基氨基、低酰氨基和N-低烷基-N-低酰氨基的群。此处所述的术语“低”表示碳原子数最多为约十个。
