Influence Of Relative Humidity And Media On Growth And Sporulation Of Colletotrichum Capsici F.Sp. Cyamopsicola Causing Anthracnose Of Cluster Bean

In this paper, the effect of different relative humidity and media on the growth and sporulation of Colletotrichum capsici f.sp. cyamopsicola was studied. Out of five relative humidity levels (viz.25,50,75,90and100 per cent) tested, 90 and 100 per cent relative humidity found most favourable for the fast growth and maximum spore production. Out of seven synthetic and non synthetic media tested, it was found that significantly maximum colony diameter and sporulation were recorded in potato sucrose agar medium followed by oat meal agar.
