Nine plant species and 7 antagonists were tested against Colletotrichum gloeosporioides which is the causal agent of fruit rot disease in the Naga king chilli. In vitro studies indicated that Trichoderma viride and Pseudomonas fluorescens were very effective in inhibiting mycelial growth of the pathogen. Among the plant extracts, Allium sativum (10%) and Azadirachta indica (10%) demonstrated the highest inhibition of mycelial growth of C. gloeosporioides. Field evaluation of effective plant extracts and antagonists and fungicide, revealed that spraying with T. viride (2%) showed a maximum disease reduction of 61.41% followed by P. fluorescens, (58.10%). However, the fungicide (Bavistin 0.1%) with 80.84% disease reduction ranked first.
