Abstract

Two field experiments was conducted in the eastern farm of Pandit Jawaharlal Nehru College of Agriculture and Research Institute (PAJANCOA & RI), Karaikal, during kharif 2018, and rabi 2018-19 in a Randomized Block Design (RBD), with eight treatments and were replicated thrice in an experimental area of 4 x 5 m2 each with rice variety of ADT 45.During kharif, the mean per cent leaf damage was low in the treatment with rynaxypyr 20 SC @ 150 ml/ha (6.68,4.81%) followed by camphor oil @ 1000 ml/ha (6.91,5.35%) with a per cent reduction of 38.20,58.49 and 36.07,53.83 per cent respectively over untreated check after two rounds of foliar application. In rabi 2018-19, the mean per cent leaf damage was low in the treatment with rynaxypyr 20 SC @ 150 ml/ha (5.57,4.34,3.02%) followed by camphor oil @ 1000 ml/ha (6.41,5.11,3.65%) with a per cent reduction of 40.42,31.44;58.90,51.60 and 69.01,63.27per cent respectively over untreated check after three rounds of foliar application. The effect of these applications also resulted on the yield attributes, with highest grain yield of 3.43 and 6.64 t/ha were observed in rynaxypyr 20 SC @ 150 ml/ha treated plot followed by dinotefuran 20 SG @ 200 g/ha (2.50 and 5.82 t/ha) and camphor oil @ 1000 ml/ha (2.28 and 5.68 t/ha) compared to the untreated check (1.33 and 4.06 t/ha) during kharif and rabi respectively. From the results of the field experiments, it was found that, the treatment with rynaxypyr 20 SC @ 150 ml/ha and among the botanicals, camphor oil @ 1000 ml/ha was found to be effective against the rice leaf folder, C. medinalis.
