%X Sodium salts of drazoxolon and related 4-arylhydrazono-3- methylisoxazol-5-ones react with acyl chlorides in dry acetone to form 2-acyl-4-arylazo-3-methylisoxazol-5-ones, the structures of which were deduced from their i.r. and u.v. spectra. Several 2-acyl-4- arylazo-3- methylisoxazol-5-ones show considerable fungicidal activity against a number of plant pathogens.
