ABSTRACT

Six insecticides spray were evaluated by taking one highly susceptible ‘T(N)1’  and another resistant cultivar, ‘Vikramarya’, under glasshouse conditions. Among the insecticides, buprofezin (@1.6 g/L) and imidacloprid (@ 0.25 ml/L) controlled the insect vector population fully without any RTD infection  in  T(N)1 after one and five days of treatment. These were significantly superior over than rest of the treatments. The spray of difenthiuron and dinotefuron @ 0.2% concentration were found effective significantly in controlling the insect vector population (94%) and  decreasing the RTD infection of 75%.  In rice cultivar, Vikramarya,  buprofezin (@1.6 g/L), imidacloprid (@ 0.25 ml/L), dinotefuran (@ 2 g/L), difenthiuron (@1.2 ml/L) full control of insect and no RTD infection at one and five days after treatment.
