abstract
A field experiment was carried out to evaluate the bio efficacy of dinotefuran 70%WG against Brown planthopper, Nilaparvatha lugens (Stal) (BPH) and White backed planthopper, Sogatella furcifera (Hoverth) (WBPH) and green leaf hopper Nephotettix virescens (Distant) (GLH) on paddy. The results revealed that application of dinotefuran 70% WG @ 61.6 g.a.i/ha was found to be excellent insecticide in suppressing the BPH population during kharif 2018 paddy crop by registering 85.24 %, 74.78 % and 85.59 % reduction over control of BPH, WBPH and GLH, respectively. The next best treatment was dinotefuran 70% WG @ 51.8 g.a.i/ha with 78.94 %, 71.27 % and 78.94 % reduction over control of BPH WBPH and GLH, respectively. The effect of these applications was also resulted on the yield attributes, with highest grain yield of 63.84 q/ha was observed in dinotefuran 70% WG @ 61.6 g.a.i/ha treated plot followed by Dinotefuran 70% WG @ 51.8 g.a.i/ha (60.76 q/ha) and did not have any severe depressing effect on the natural enemies in the field when applied at recommended doses.
