Abstract:

An experiment was conducted during Kharif season of 2017-2018 at the Central Research Farm of Sam Higginbottom University of Agriculture Technology and Sciences, to evaluate the efficacy of bio-agents and botanical extracts against anthracnose (Colletotrichum lindemuthianum) of black gram (Vigna mungo L.) both in vitro and in vivo. In vitro studies showed significant difference in the inhibition per cent of mycelial growth of the pathogen among all the treatments. Among the bio-agents, Trichoderma harzianum was found most effective and recorded 5.33 mm mean colony diameter and recorded significantly highest growth inhibition (93.59 %) of the test pathogen as compared to carbendazim (treated check) and untreated control which was followed by Psuedomonas fluorescens with 61.92 per cent growth inhibition. Among the plant extracts, datura leaf extract @ 5% showed the minimum percent of inhibition (10.22 %) of the pathogen followed by neem leaf extract @ 5% (20.84). In field evaluation, a significant difference in the percent disease intensity was observed among all the treatments, the minimum disease intensity (%) was recorded in Trichoderma harzianum @ 8g (23.53%), as compared to carbendazim (treated check) and untreated control respectively, followed by Trichoderma harzianum @ 6g (24.68 %), Trichoderma harzianum @ 4g (28.76 %), Psuedomonas fluorescens (29.21 %) and neem leaf extract @ 5% (33.9 %) and maximum disease intensity (%) was recorded in datura leaf extract @ 5% (35.97).
