Abstract: An attempt was made to study a leaf blight disease caused by Rhizoctonia solani, which is considered as one of the major problem in strawberry cultivation causing considerable damage. Thus an investigation was programmed at Regional Agricultural Research Station, Ambalavayal, Wayanad and conducted to study the epidemiological parameters that lead to the disease and to find a better management strategy against the disease using fungicides and bio-control agents. Fungicides viz., carbendazim 12% + mancozeb 63% (Saaf), carbendazim 50WP (Bavistin), propineb 70WP (Antracol) and Bordeaux mixture inhibited the pathogen by cent per cent and cymoxanil 8% + mancozeb 64% (Curzate M8) at all concentrations recorded a per cent inhibition of 77 to 80. Biocontrol agent Trichoderma asperellum completely inhibited the pathogen by overgrowth mechanism and Pseudomonas fluorescens exhibited 55.56 per cent inhibition.
