Seed biopriming and spraying at fruit set with microbial agents suppress anthracnose disease and improve growth and yield in chilli

P. V. Athira, N. V. Radhakrishnan, K. N. Anith


Anthracnose caused by Colletotrichum capsici (Syd.) Butler and Bisby is a major disease of chilli (Capsicum annuum L.) resulting in a yield loss from 8 to 60 percent in India. Most of the commercial chilli varieties are susceptible to the disease. Present study reports potential of seed biopriming and spraying with biocontrol agents at fruit-set stage for the management of anthracnose disease in chilli (var.Vellayani Athulya). Three biocontrol agents viz., Trichoderma asperellum, Bacillus subtilis VLY 62 and Bacillus amyloliquefaciens VLY 24 were compared with chemical check (Carbendazim 0.1%) and untreated control for disease management and growth promotion. Seed biopriming and spraying with B. amyloliquefaciens at a concentration of 108 cfu mL-1 was the most effective treatment in reducing the disease. Biopriming alonealso exhibited significant reduction.
