Abstract:
The field experiment conducted at research farm of Tirhut College of Agriculture (TCA), Dholi which lies in the district of Muzaffarpur, a sub campus of “Dr. Rajendra Prasad central agricultural University (RPCAU)” Pusa, Samastipur, Bihar for evaluating bio-efficacy of two doses of chlorantraniliprole 18.5 SC (30 and 60 g a.i./ha) and two dose of indoxacarb 14.5 SC (75 and 150 g a.i./ha) against tomato fruit borer (Helicoverpa armigera) during Rabi, 2020 in tomato crop. Result revealed that chlorantraniliprole 18.5 SC @ 60 g a.i./ha was reduce larval population of H. armigera as well as lowest per cent of fruit damage compared to control. The treatment chlorantraniliprole 18.5 SC @ 60 g a.i./ha was found most effective against fruit borer on tomato crop, which was statistically at par with chlorantraniliprole 18.5 SC @ 30 g a.i./ha and both significantly superior from rest of the treatments.
