Novel herbicidal compounds, compositions containing them, and methods for their use in controling weeds are disclosed. The novel herbicidal compounds are optionally substituted phenylmethoxy or phenylmethylthio heterocycles of the formula: ##STR1## in which Q is selected from: ##STR2## R=halogen; R.sup.1 =lower alkyl, lower alkoxy, lower haloalkyl, lower haloalkoxy, lower alkylthio, lower sulfonyl, or lower alkylsulfinyl; R.sup.2 =lower alkyl, or lower haloalkyl; X=H, halogen, or lower alkyl; W=O or S; Z, Z.sup.1, Z.sup.2 are independently selected from H, halogen, straight or branched chain lower alkyl, lower alkoxy, is lower haloalkoxy, cyano, lower cyanoalkyloxy, or aryl; or Z and Z.sup.1 are adjacent to each other on the benzene ring, and taken together are --(CH.sub.2).sub.4 --; or Z.sup.2 is OA in the 2-, 3-, or 4-position of the phenyl ring; A is a derivative of an alkanoate bonded to the phenoxy oxygen at the alpha carbon; R.sup.3 is H or lower alkyl; R.sup.4 =OH or an agriculturally acceptable salt thereof, straight or branched chain lower alkoxy, lower haloalkoxy, alkoxyalkoxy, alkoxyalkoxyalkoxy, amino, lower alkylamino, lower alkylsulfonylamino, or lower (alkyl)(alkylsulfonyl)amino; and R.sup.5 =halogen or lower alkyl ester.
揭示了新型除草化合物、含有它们的组合物以及在控制杂草中使用它们的方法。这些新型除草化合物是可选择的取代苯甲氧基或苯甲硫基杂环化合物,其化学式为:##STR1## 其中Q从以下选取:##STR2## R=卤素;R.sup.1=较低烷基、较低烷氧基、较低卤代烷基、较低卤代烷氧基、较低烷硫基、较低磺酰基或较低烷基亚砜基;R.sup.2=较低烷基或较低卤代烷基;X=H、卤素或较低烷基;W=O或S;Z、Z.sup.1、Z.sup.2独立地选自H、卤素、直链或支链较低烷基、较低烷氧基、较低卤代烷氧基、氰基、较低氰基烷氧基或芳基;或Z和Z.sup.1相邻于苯环上,一起取为--(CH.sub.2).sub.4--;或Z.sup.2是OA在苯环的2-、3-或4-位置;A是与苯氧基上的α碳键合的烷酸酯衍生物;R.sup.3=H或较低烷基;R.sup.4=OH或其农业可接受的盐,直链或支链较低烷氧基、较低卤代烷氧基、烷氧基烷氧基、烷氧基烷氧基烷氧基、氨基、较低烷基氨基、较低烷基磺酰氨基或较低(烷基)(烷基磺酰基)氨基;和R.sup.5=卤素或较低烷基酯。
