Management of Cotton Leaf Curl Virus Disease and its Vector through In Vivo Evaluation of Organic Nutritional Amendments, Organic Oils and Insecticides

Muhammad Humza, Babar Iqbal and Safdar Ali

Cotton (Gossypium hirsutum L.) is the most important cash crop having a great agro-economic significance throughout the world. Cotton leaf curl virus (CLCuV) is the most devastating pathogen of cotton, which is responsible for causing huge economic yield losses. The present study was focused on the application of organic nutritional amendments (farm yard manure, spent compost, decomposed leaves compost and kitchen waste compost) in the soil for the enhancement of plant vigor as well as for increasing the ability of plants to survive against the viral attack. The applications of organic oils (canola, sunflower and cotton seed) were done at 25% concentration (25% oil and 75% vinegar) on young cotton plants in order to create hurdle against insect vector infestation (Bemisia tabaci Genn.) and insecticides (Imidiacloprid (Imidacloprid 25% WP), Megamos (Acetamparid 20% SC and Bifenthrin (Bifenthrin 10% EC)) were sprayed at their standard doses in the field for maximum mortality of whitefly (Bemisia tabaci Genn.) with 7 days interval. The trial was conducted at the research area of Department of Plant Pathology, University of Agriculture, Faisalabad under randomized complete block design (RCBD) with three replications. The recorded data was subjected for analysis of variance (ANOVA) and the means were compared using least significance difference (LSD) test.
