Abstract

Two antifungal antibiotics, mycobacillin and versicolin, were studied as agricultural fungicides in the control of fungal infection of rice and jute. Mycobacillin is especially active against Piricularia oryzae at a concentration of 10 μg/ml, and versicolin against Colletotrichum gloeosporioides at a concentration of 2.5 μg/ml. Mycobacillin has no adverse effect on germination of seeds and growth of seedlings of rice and jute plants at a concentration of 500 ppm, even for prolonged exposure (24 or 48 hours); in fact, it is stimulatory. On the other hand, versicolin has showed detectable phytotoxicity at 500 ppm for prolonged exposure.
