Abstract: Bio-efficacy of newer insecticide molecules against jassid (Amrasca biguttula biguttula) on brinjal crop research work were carried out during Rabi season of 2022-23 at the research cum instructional farm of department of Entomology, Indira Gandhi Krishi Viswavidyalaya, Raipur (C.G.). Bio-efficacy of different treatments viz., Sulfoxaflor 3.7% + Bifenthrin 11.2% SC at three different doses of 22+67, 30+90, and 37+114 g. a.i. /ha along with single dose of Sulfoxaflor 24% Sc (37 g. a.i. /ha), Bifenthrin 10% SC (114 g. a.i/ha), Fenvalerate 20.0% EC (100 g. a.i. /ha), and Cypermethrin 25.0% EC (50) g. a.i. /ha reveled that all the treatments were found significantly effective in reducing the population of jassid. The most effective treatment in reducing the population of jassid was Sulfoxaflor 3.7% + Bifenthrin 11.2% SC (37+114) g. a.i./ha followed by Sulfoxaflor 3.7% + Bifenthrin 11.2% SC (30+90) g. a.i./ha. The Cypermethrin 25.0% EC (50) g. a.i. /ha was found least effective but it was significantly superior over control.
