Isolation and in vitro evaluation of fungicides against anthracnose of sorghum caused by Colletotrichum graminicola

Abstract

Sorghum is subjected to several diseases at all the stages of its development. Sorghum belongs to the family poaceae. It is one of the most important cereal crops in india, it stands fifth most important world cereal crop after wheat, rice, maize and barley. Among all the diseases infecting sorghum, anthracnose caused by Colletotrichum graminicola is one of the most destructive foliar diseases in sorghum. According to present investigation under in vitro conditions, followed by eight fungicides i.e, (five systemic and three non-systemic) were used at different concentrations 100ppm, 500ppm, 1000ppm were tested by Poison Food Technique to know their inhibitory effect on the growth of anthracnose of Colletotrichum graminicola. According to the present investigation Mancozeb, Propiconazole, Carbendazim and Bavistin shows high inhibiting growth of mycelium, where as the fungus inhibiting growth was recorded very poor in Hexaconazole, Chlorothalonil, Propineb and Difenconazole.
