PLANT GROWTH REGULATION AGENT AND FUNGICIDE AND ACTIVE COMPONENT PRODUCTION METHOD

摘要

Azole derivs. of formula (I), their acid addn. salts and metal salt complexes are new. R is alkyl or opt. substd. cycloalkyl or phenyl. X is nitrogen or CH. Y is OCH2, CH2CH2 or CH=CH. Z is halo, alkyl (opt. substd. by halo), cycloalkyl, alkoxy or alkylthio (both opt. substd. by halo) or opt. substd. phenyl, phenoxy, phenylalkyl or phenylalkoxy. m is 0-3. Also new are intermediates of formula (II). (I) are useful as fungicides (esp. against true mildews such as Erysiphe species and have both preventative and systemic actions and as plant-growth regulators. Typical responses include inhibiting vegetative growth of cereals etc., increasing sugar content of beet, and protein content of soya; stimulating latex flow in rubber trees; induction of parthenocarpic fruiting; breaking apical dominance, defoliation, acceleration of ripening; improving resistance to adverse climatic conditions etc. They are more effective than known cpds. such as 2-chloroethylphosphonic acid.
