EFFICACY OF SOME BIOAGENTS AGAINST SCLEROTIUM ROLFSII SACC. CAUSING ROOT-ROT IN ZEA MAYS L. CROP
Ganesh Prasad and S. K. Dwivedi*
ABSTRACT
Sclerotium rolfsii is a saprotroph fungus with living plants. Sclerotium rolfsii is a soil-borne fungus which causes root-rot in Zea mays crop. Zea mays is a staple food in many regions of the world. It is a good nutritional crop which contains proteins, carbohydrates, fats and vitamins (B-complex, A, C & K). It maintains various organs of the body like hair, skin, digestive system, heart, liver, kidney and brain. Zea mays contain selenium element that helps proper function of the thyroid gland which maintains immune system of human body. Sclerotium rolfsii was isolated from infected maize from Barabanki district of Uttar-Pradesh. Penicillium spp., Trichoderma viride, Aspergillus niger and Aspergillus flavus were isolated from rhizospheric soil of maize. Bio-agents Penicillium sp. (30.20%, 35.82%, 44.22%), Trichoderma viride (3.21%, 23.48%, 26%), Aspergillus niger (22.43%, 40.98%, 49.02%) and Aspergillus flavus (25.18%, 27.96%, 34.39%) on 3rd, 5th, 7th day inhibited the mycelial growth of Sclerotium rolfsii using under dual culture technique. Penicillium sp. and A. niger were more effective antagonists than Trichoderma viride and Aspergillus flavus against mycelial growth of S. rolfsii under in vitro condition.
Keywords: Zea mays, Sclerotium rolfsii, Penicillium spp., Trichoderma viride, Aspergillus niger and Aspergillus flavus.
