Sheath blight of rice incited by Rhizoctonia solani Kuhn is a potential threat to rice cultivation causing yield loss ranging
from 1.2 to 69.0%. Host resistance against sheath blight is not available so far. Fungicidal approaches for its control are
damaging to the environment. Eco-friendly approaches have attained importance in modern agriculture to curtail the hazards
of extensive use of toxic chemicals for disease control. The present study was undertaken to assess the disease severity,
percent disease incidence (PDI) and yield parameters against sheath blight of rice through different combinations of
treatments in the field during 2013 and 2014. Among the eco-friendly approaches assessed against sheath blight of rice, soil
application of combination of Trichoderma harzianum + Pseudomonas fluorescens + Farm Yard Manure prior to
transplanting followed by foliar spray of zinc sulphate (0.5%) + lime (0.25%) at maximum tillering stage showed the
maximum reduction in sheath blight severity (50%), percent disease incidence (55.46%) and higher grain yield (28.55%)
over the control. The ears and 1000 grain weight showed positive correlation with grain yield. The treatments possessing soil
application of bio-agents + FYM/ vermi-compost prior to transplanting showed greater number of tillers per hill
comparatively to no application in the soil.
