Triazole and imidazole derivatives of the formula: …<CHEM>… wherein R1 is H, optionally substituted alkenyl or alkynyl, or OSi (CH3)3;… R2 is alkyl, vinyl or optionally substituted phenyl;… R3 is alkyl, optionally substituted phenyl, hydroxy or alkoxy;… R4 is H or CH3;… A is CH or H;… and salts and metal complexes thereof, exhibit potent fungicidal activity. The compounds may be used to control fungus diseases of living plants, for which purpose they may be formulated into fungicidal compositions in conventional manner. …<??>The novel compounds may be made e.g. by reacting an appropriate chloromethylsilane of formula: …<CHEM>… with an alkali metal salt of 1,2,4-triazole or imidazole. |
