FUNGICIDAL TRIAZOLE AND IMIDAZOLE COMPOUNDS

摘要

Compounds of the general formula wherein A is CH or N; X is F, Cl or Br; R1 is H or C1-C4 alkyl R2 is alkyl, cycloaklyl or optionally substituted phenyl; and their salts with protic acids, and complexes with metal ions; exhibit potent fungicidal activity. The compounds may be used for controlling fungal diseases of plants. The novel compounds may be made by reacting a corresponding starting material wherein X is OH with a suitable halogenating ageht.
