Abstract:
Identification and characterization of various Colletotrichum diseases isolated from various crop such as soybean, sugarcane, chilli, turmeric, bean, mango and strawberry is studied. Three isolates of each crop was collected from different geographical location of chhattisgarh and was maintained for morphological variation such as in Setae, conidial shape, mycelium and growth pattern was observed. The various species confirmed morphological difference which includes Colletotrichum acutatum, C. truncatum, C. capsicii, C. lindemuthiaum and C. falcatum on the respective crop. The three isolate morphologically similar with C. acuatum produce falcate conidia, and developed dark grey colony color, The Colletotrichum acutatum C. capsii and C falcatum is easily differentiated with C. gleosporoides and C frageriae with the colony color and growth rate on Potato dextrose Agar plate. All the species differ from one another via acrevuli forming and non acervulli forming along with formation of setae. This was characteristics difference for the morphological variability undertaken in the study.
