Abstract

Colletotrichum (teleomorph Glomerella) is an important plant microbe that affects agricultural and plantation crops across the world. It adheres to the hemi-biotrophic mode of feeding, in which both biotrophic and necrotrophic stages occur sequentially. Pathogenic variability among Colletotrichum species affecting various crops as mango (anthracnose), strawberry (fruit rot), chilli (anthracnose), turmeric (leaf blight), soybean (pod blight), bean (anthracnose) and sugarcane (red rot). These naturally infected seven crops were collected from different growing regions of Chhattisgarh. The assay with four fungicides namely Chlorothalonil 75 % WP, Difenoconazole 25 % EC, Azoxystrobin 18.2 % EC and Tebuconazole 50 % + Trifloxystrobin 25 % w/w were checked at four concentration 50,100,250 and 500 ppm with all the fungal culture and effective amount of control was observed especially with Difenoconazole 25 % EC fungicide.
