NEW Fangled Tactics Towards Cotton Leaf Curl Virus Disease A Review

Abstract

CLCuVD is the most ravaging biotic stress to cotton crop and is responsible for the withdrawal of various varieties in cotton cultivation across the globe. CLCuV significantly degrades the quality and productivity of cotton. This notorious viral disease is transmitted by whitefly (Bemisia tabaci Genn)vector. It is challenging to manage this viral disease because of higher recombination rate of viral strains. This virus has broad host range and attacks various host plants like tobacco, tomato, and okra, while new viral strains evolved due to mixed farming practices. CLCuV has been managed by cultural practices and control of insect vector. Various techniques which include netting, use of plant extracts, pathogen-non-pathogen derived approaches, RNAi, CRISPR-cas, biological control and other existing knowledge related to its management is discussed here. Limited research has been conducted to evaluate the efficacy of nanoparticles as an antiviral agent. There is a dire need to explore the mechanisms underlying the role of NPs in the CLCuV- vector interactome. The present manuscript is expected to be fruitful for the further investigation on cutting edge research areas.
