1-Alkyl-4-benzoyl-5-hydroxypyrazole compounds in which the benzoyl moiety is substituted in the 2-position with a halo, alkyl, or alkoxy group, in the 4-position with an alkylsulfonyl group, and in the 3-position with an optionally substituted phenyl group, for example, 1-(1,1-dimethylethyl)-4-(2-methyl-4-methylsulfonyl-3-(4-methoxyphenyl)benz oyl-5-hydroxypyrazole, were prepared and found to be useful for the control of a variety of broadleaf and grassy weeds. The compounds can be applied either preemergently or postemergently and can be used to control undesirable vegetation selectively in small grain crops and turf or non-selectively.
1-烷基-4-苯甲酰-5-羟基吡唑化合物,其中苯甲酰基在2位被卤素、烷基或烷氧基取代,在4位被烷基磺酰基取代,在3位被可选择取代的苯基取代,例如,1-(1,1-二甲基乙基)-4-(2-甲基-4-甲磺基-3-(4-甲氧基苯基)苯甲酰-5-羟基吡唑,已制备并发现对控制各种阔叶和禾本科杂草有用。这些化合物可以在种植前或种植后施用,并可用于有选择性地控制小麦作物和草坪中的不良植被,或者非选择性地控制植被。
