Abstract:
Rice is second most important cereal crop of world and the staple food for more than half of the world’s population. It provides 20 percent of the world’s dietary energy supply followed by Maize and Wheat. Foliar diseases of Rice, mainly Sheath blight caused by Rhizoctonia solani, blast incited by Pyricularia oryzae and brown leaf spot (Drechslera oryzae) are three major devastating diseases in Karnataka during Kharif (wet) season. Now these diseases are also appearing in various part of Karnataka during summer season also which was not so common in earlier period which has become a serious problem for successful cultivation of paddy. Therefore, a field experiment was carried out to know the efficacy of carbendazim 25% + mancozeb 50% WS under filed condition against sheet blight, blast and brown leaf spot of rice during 2016 and 2017, at College of Agriculture, Shivamogga. Experimental results revealed that all the treatments significantly reduced the incidence of sheath blight, blast and brown leaf spot where lowest Percent disease index (PDI) was recorded in (Carbendazim 25% + Mancozeb 50% WS) + Urea (312.5 + 625 g a.i./ha) which was on par with Carbendazim 25% + Mancozeb 50% WS + Urea (250 + 500 g a.i./ha) in case of all three diseases under field condition with yield of 39.00 and 38.70 q/ha respectively.
