Abstract

NEW MATERIAL:A pyrazole derivative expressed by formula I (X and Y are halogens, nitro groups or CF3s; Z is halogen).
EXAMPLE: 1,3-Dimethyl-4-( 2,4-dichlorobenzoyl )-5-( 1,1-dimethyl-2-chloropropionylmethoxy)pyrazole.
USE: A herbicide capable of remarkably controlling harmful weeds, e.g. Panicum crus-galli L. var. frumentaceum Trin., Cyperus microiria STEUD. or Sagittaria pygmaea Miq. without substantial damage to crops, e.g. rice plants, and suitably selected for soil and foliar treatment in paddy fields, plowed fields, fruit gardens and mulberry farms. The amount of application is 10W100mg per are calculated as the active constitutent.
PROCESS: A compound of formula II is reacted with a compound of formula III (Hal is halogen) in a solvent in the presence of an alkaline substance, e.g. potassium carbonate, and preferably a cuprous halide catalyst, at the refluxing temperature or below for 1W10hr to give the compound of formula I.
