BIOCONTROL OF FRUIT ROT OF CAPSICUM USING ANTAGONISTIC MICROORGANISMS

摘要

Capsicum commonly called red pepper (Capsicum annuum var, longum) is a prominent summer vegetable and spice crop in India It is grown in tropical and subtropical regions of the world. The impediment for its cultivation is the susceptibility to large number of fungal pathogens of which fruit rot caused by Colletotrichum capsici (Syd.) Butler and Bisby was most important. The loss was estimated at 30.7 per cent in Tamil Nadu (Sujathabai, 1992) and 20-60 per cent in Punjab and Haryana States of India (Bansal and Grover, 1969). Not much information is available on control of this disease using non-chemical methods particularly antagonistic microorganisms. The present investigation was carried out to test the efficacy of two antagonists (Trichoderma viride and T. harzianum) against nine isolates of C. capsici.
