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.

摘要

在这项研究中，试图检查由合成纤维和天然纤维(分别为Carbon和Cordia Dichtotoma)组成的混合复合材料是否可以生物降解，至少在一定程度上不会对机械性能造成太大影响. 采用手糊法将碱处理过的二歧虫草和碳纤维增强为环氧树脂，制备了杂化复合材料. 通过改变复合材料试样中纤维层的数量，并为所有复合材料固定20%的纤维重量，制备了九种不同的试样组合. 纯碳纤维复合材料的最大拉伸强度为386.68 MPa，弯曲强度为647.08 MPa，冲击能为4.82 J，而杂化复合材料的拉伸强度为367.76 MPa，弯曲性能为646.41 MPa，冲击能量为4.74 J. 使用扫描电子显微镜(SEM)研究了测试样品的纤维和基体之间的界面结合，以及所制造的复合材料的纤维在基体内的排列. 热重分析(TGA)用于研究热稳定性，发现其在高达415°C时是热稳定的.9.结晶度值从20%的碳纤维增加到20%的碱纤维.
