“…Ghosh et al (2013) and Chander et al (2012) revealed that sulfoxaflor 14SC was highly effective. Naik et al (2016) reported that pymetrozine 50 WG @ 0.6 g/ l and imidacloprid + ethiprole @ 0.25 g/ l are effective. Shankar et al (2018) observed that sulfoxaflor 24SC @ 375 ml/ ha is superior, while Guruprasad et al (2016) revealed that sulfoxaflor 24SC @ 438.0 ml/ ha was the best.…”

Efficacy of some insecticides (pymetrozine 50WG, sulfoxaflor 24SC and imidacloprid 17.8SL) was evaluated against rice white backed plant hopper (WBPH) Sogatella furcifera Horvath. Sulfoxaflor 24SC @218.7 g a.i./ ha and pymetrozine 50WG @ 187.5 g a.i./ ha gave significantly results (7.57 and 7.82/ hill, respectively).However, highest grain and straw yield (40.87 and 64.33 q/ ha) was observed with pymetrozine 50WG@ 187.5 g a.i./ ha and sulfoxaflor 24SC @ 218.7 g a.i./ ha (40.41 and 64.22 q/ ha). Regarding incrementalcost benefit ratio (ICBR), it was observed that maximum ICBR was obtained with pymetrozine 50 WG@ 187.5 g a.i./ ha (1: 3.55) followed by sulfoxaflor 24SC @ 218.7 g a.i./ ha (1: 2.99). Thus, pymetrozine 50WG at 187.5 g a.i./ ha and sulfoxaflor 24SC at 218.7 g a.i./ha can be recommended against rice WBPH.

“…Kirankumar, 2016 studied the efficacy of Pymetrozine 50 WG against brown plant hopper of rice and found it is quite effective for N. lugens management and pymetrozine treated plots gave higher yield with least effect on natural enemies. (Naik et al, 2016) also mentioned the effectiveness of Pymetrozine 50 WG @ 0.6 g l -1 and Glamore (Imidachloprid+Ethiprole) @ 0.25 g l -1 of water for hoppers management.…”

A field experiment was conducted to determine the comparative efficacy of some newer insecticides with some conventional insecticides against brown plant hoppers (BPH) in rice during kharif 2014 and rabi, 2014-2015. The treatments include: Thiamethoxam 25 WG @ 37.50 g a.i. ha-1 , Lamda cyhalothrin 5 EC @ 30 g a.i. ha-1 , Pymetrozine 50 WG @ 150 g a.i. ha-1 , Buprofezin 25 SC @ 250 g a.i. ha-1 , Glamore (Imidachloprid 40+Ethiprole 40% w/w) 80 WG @ 100 g a.i. ha-1 , Dinotefuran 20 SG @ 40 g a.i. ha-1 , Acephate 75 SP @ 564 g a.i. ha-1 , untreated control and a basal application of fipronil 0.3 G @ 25 kg ha-1 was made once at 25 DAT in all treatments except untreated control. All the treatments were effective for hoppers management than control. The overall data revealed that the Pymetrozine 50 WG @ 150 g a.i. ha-1 recorded significantly higher percent reduction of hoppers and higher grain yield than the other treatments. Pymetrozine 50 WG @ 150 g a.i. ha-1 treated plot also had more number of spiders (3.71 spiders 10 hills-1 after 10 DAT of last spray) than other chemical treated plots. In cost benefit ratio it is observed that the Pymetrozine 50 WG @ 150 g a.i. ha-1 (1:4.18) and Lamda cyhalothrin 5 EC @ 30 g a.i., ha-1 (1:4.46) treated plots had more return than expenditure. 2. Materials and Methods The experiment was conducted in the experimental farm of Regional Research and Technology Transfer Station (OUAT), Chiplima, Sambalpur, Odisha, during kharif, 2014 and rabi, 2014-15 in Randomized Block Design (RBD), having 8 treatments which were replicated thrice in a net experimental area of 5×4 m 2 each. The Station is situated at 20°21΄ N latitude and 80°55΄ E longitude in Dhankauda block of Sambalpur district at an altitude of 178.8 MSL. The climate of the area is warming sub-humid. The temperature varies from as low as 9 °C to as high as 44.2 °C. The mean maximum and the mean minimum temperatures of 40.5 °C and 13 °C are recorded in BPH, cost benefit ratio, insecticides, rice, yield
