In order to meet the agricultural requirement for the expanding population, pesticides have been used regularly even with their severe threat. The uncontrolled use of these pesticides can cause irreparable damage to both soil and plant-associated microbiome. Therefore, an environment friendly alternative to enhance plant productivity and yield is highly important. Here comes the importance of endophytic microorganisms with multi-plant beneficial mechanisms to protect plants from the biotic and abiotic stress factors. However, their performance can be negatively affected under pesticide exposure. Hence the present study was conducted to analyse the tolerating ability of a Bacillus sp. Fcl1 which was originally isolated from the rhizome of Curcuma longa towards the pesticide quinalphos and also its ability to reduce the quinalphos-induced toxicity in Vigna unguiculata. The results revealed that the viability of endophytic Bacillus sp. Fcl1 depended on the concentration of quinalphos used for the study. Further, Fcl1 supplementation was found to alleviate the quinalphos-induced toxicity in Vigna unguiculata seedlings. The study is environmentally significant due to the pesticide tolerating and alleviating effect of Bacillus sp. Fcl1 in quinalphos-induced plant toxicity. This could suggest the application of microbes of endophytic origin as an efficient bioinoculant for field application even in the presence of pesticide residues.
