A field experiment was carried out during kharif 2020, at the Agricultural College Farm, Bapatla to evaluate the efficacy of some insecticides in combination with neem against rice planthoppers in direct seeded rice crop. The results showed that triflumezopyrim 10.6SC @ 25g a.i. ha-1 was the most effective treatment against both brown planthopper Nilaparvata lugens (Stål) and white backed planthopper Sogatella furcifera (Horváth) with 73.61 and 77.69% reductions over untreated control, respectively at 5 DAT. The other effective treatments were dinotefuran 20SG @ 40 g a.i. ha-1 and pymetrozine 50WG @ 150 g a.i. ha-1 with 70.14 and 66.44% reduction of N. lugens and 71.89 and 69.66% reduction of S. furcifera, respectively over untreated control at 5 DAT. Neem formulation 1500 ppm revealed the lowest efficacy with 34.95 and 36.19% reduction of N. lugens and S. furcifera over the untreated control at 5 DAT.
