PURPOSE: An agricultural and horticultural fungicide, capable of controlling various plant pathogenic fungi, e.g. Piricularia oryzae or Sphaerotheca fuliginea, having a wide antifungal spectrum and a great antifungal activity without phytotoxicity, and comprising a specific indole compound as an active constituent. n CONSTITUTION: A fungicide comprising one or more types of indole compounds of formula I [R 1 is H, lower alkyl, benzyl group, etc.; R 2 is formula II (X is H, halogen, lower alkyl group, etc.; n is 1 or 2), naphthyl, pyridyl group, etc.; R 3 is H, halogen, phenyl group, etc.; R 4 and R 5 are H, halogen, lower alkyl groups, etc.], as an active constituent, alone or together with an inert carrier, formulated by the conventional techniques. The fungicide is effective against blast, and helminthosporium leaf spot, particularly powdery mildew of cucumbers, has a wider antifungal spectrum and a greater activity than the well-known similar compounds without phytotoxicity. n COPYRIGHT: (C)1980,JPO&Japio |
