FUSARIUM AND VERTICELLUM WILT IN COTTON: A REVIEW

Abstract

Cotton (Gossypium hirsutum) is an important cash crop which is cultivated in more than 80 countries worldwide producing worth of 121.30 million bales in MY 2019/2020. However, it is attacked by many insect pests that causes high economic loss. Vertcillium wilt (VW) and Fusarium wilt (FW),a soil borne fungus caused by Verticillium dahlia kleb and Fusarium oxysporum f.sp. vasinfectum, is one of the most destructive diseases in cotton (Gossypium hirsutum L.) production deleteriously affecting the yield and quality in ,India and worldwide. The wilt is becoming serious problem for cotton growing farmer and key subject of research in cotton resistance genetics and pathology. This aim of this paper is to call for attention and concentrated action by describing potentially damage of the pest, morphology, symptoms, Epidemiology, behavior, entry pathways and control method. The key pest of cotton accounts for its production loss up to70% in the absence of compatible control measures. Its effective control strongly relies on integrated management strategies includes Bio control agents, Physical, cultural a virulent strains, resistant varieties are the best practices for pest management.
