ABSTRACT: The study was conducted from September 2019 to December 2020 to know the effects of the new generation insecticides, Virtako 40WG (Chlorantraniliprole and Thiamethoxam) and Coragen 18.5SC (Chlorantraniliprole) on the infestation of rice yellow stem borer (Scirpophaga incertulas) and dark headed stem borer (Chilo suppressalis) and yield of rice. The insecticides with concentrations 0.1, 0.5, 2, 10, 50 and 200 ppm were applied along with an untreated control. Rice plants were cultivated in the experimental field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh. All doses of the insecticides resulted significantly lower level of plant infestation. Virtako 40WG and Coragen 18.5SC at concentrations of 200 ppm showed the lowest levels of dead heart (3.0% and 2.0%, respectively) and white head (2.7% and 2.2%, respectively) symptoms. All the doses of the insecticides produced significantly the higher yield of rice compared to untreated control and the dose 200 ppm produced the highest yield.
Keywords: Aman rice,Chilo suppressalis, Coragen 18.5SC, Scirpophaga incertulas, Virtako 40WG.
