Efficacy of different bioagents seed treatment for controlling seed-borne Colletotricum sp. in chilli (Capsicum annum L.)

Abstract

In tropical and subtropical areas, Colletotrichum capsici, which causes chilli anthracnose, is a significant barrier to the production of chillies. Study was aimed mainly to find the efficacy of various bioagents on the germination, seedling length and seedling vigour of C. capsici infected chilli seeds. Rudra and Byadagi are the two agronomically superior varieties selected for the study. Among all the treatments Trichoderma viride were found superior and significantly higher seed germination, seedling length, seed vigour index as compared to other treatments and control. Among the various bioagents, In the variety Rudra the highest germination percentage of 97.66%, The root length, shoot length, seedling length of T1 were 6.4 cm, 5.7 cm, 12.19 cm and seed vigour index of 1184.49 were obtained in T1 (2.5 ml of Trichoderma viride). In the variety Byadagi highest germination percentage of 95.33% , The root length, shoot length, seedling length were 6.87 cm, 5.6 m, 12.47 cm, The seed vigour index of 1196.79 were obtained in T2 (5 ml of Trichoderma viride). Among the bioagents Trichoderma viride, Pseudomonas fluorescens performs well and antagonists against the pathogen.
