Biotic stress alleviating strategies in chickpea

Abstract

The third-most important food legume in terms of economic importance worldwide is the chickpea (Cicer arietinum L.). Its potential production is frequently constrained by numerous biotic stressors, such as the nematodes, insects Ascochyta blight, fusarsium wilt, and botrytis grey mould are the three major fungal diseases that cause significant economic losses, while Helicoverpa armigera, Aphis craccivora, cowpea weevil are the three major pre-harvest pest of chickpea. Several biological, chemical, cultural and, agronomical practices are used to control biotic stress, apart from that few modern biotechnological approaches also developed for high yielding and biotic stress resistant varieties. This paper aims to elaborate about different biotic stresses that affect Chickpea plant, their management strategies including traditional chemicals and adaptation of transgenic varieties with their limitations and also enlightened newer ray of hope i.e., plant growth promoting rhizobacteria that holds the ability to combat against biotic stress by mitigating stress ethylene level.
