Abstract:
Rice is one of the most important food crop among all the cereals which provide stable diet over all the rice growing countries and world. Asia is a largest producer of rice in cereal crops. Chhattisgarh is known as “bowl of rice” in India, which is covered 70% of net shown area. After Blast, sheath blight is the second destructive disease of rice which causes economic loss in rice growing areas. Under lowland growing condition yield loss ranges between 5 to 10% in tropical Asia. Sheath blight of rice is a necrotrophic pathogen and due to their wide host range nature only application of fungicides provides effective management of disease under field conditions throughout the world. All the tested fungicides were observed effective in preventing the fungal growth under in vitro condition. The Bio-efficacy studies of Pseudomonas fluorescens, Trichoderma viride (T14 and IRRI2) and Trichoderma harzianum (94a) for management of sheath blight of rice were showed significant reduction in the disease severity over control. Decrease in disease development over control with or without fungicide combination. All the tested genotypes, fourteen were showed resistance against sheath blight disease of rice under the field evaluation.
