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-methyl-sulfonyl-3-(4-methoxyphenyl)benzoyl-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.
取代苯甲酰基在2-位置带有卤素、烷基或烷氧基,4-位置带有烷基磺酰基,3-位置带有可选取代苯基的1-烷基-4-苯甲酰基-5-羟基吡唑化合物,例如,1-(1,1-二甲基乙基)-4-(2-甲基-4-甲磺酰基-3-(4-甲氧基苯基)苯甲酰基)-5-羟基吡唑,已制备并发现其对多种阔叶和禾本科杂草的控制有用。这些化合物可以在发芽前或发芽后施用,并可用于选择性地控制小谷物作物和草坪中的不良植被或非选择性控制。
