Abstract


The study was undertaken to evaluate the antifungal potential of selected organic preparations, botanicals and non-hazardous chemicals under in vitro against Rhizoctonia solani Kuhn causing sheath blight in rice. A total of twenty treatments were tested for their efficacy in inhibiting the mycelial growth of R. solani. Among the treatments, six treatments viz., garlic extract (10%), fermented weed (Setaria barbata) extract (100%), fermented egg-lemon juice extract (10%), potassium silicate (1%), lime solution (12.5%) and panchagavya (5%) showed cent percent inhibition of R. solani in potato dextrose agar medium. Further, dipping the sclerotia for different time intervals in the most effective six treatments, fermented egg-lemon juice extract (10%), fermented weed extract (100%), lime solution (12.5%) and panchagavya (5%) completely inhibited the mycelial regeneration from sclerotia at 24 h after dipping and garlic extract (10%) could inhibit only 72 hours after dipping and potassium silicate (1%) resulted only in less inhibition (27.28%) even after 72 hours of dip. Thus, the study revealed the possibility of eco-friendly management of rice sheath blight disease using organic preparations or botanicals or non-hazardous chemicals.
