Abstract:
Investigation entitled “Bioefficacy of Newer Insecticides and Botanicals against Shoot and Fruit Borer, Leucinodes orbonalis Guen. on Brinjal” was carried out at Horticulture farm, S.K.N. College of Agriculture, Jobner (Rajasthan) in Kharif, 2017. Out of seven newer insecticides and two botanicals tested against shoot and fruit borer on brinjal, flubendiamide 48 SC, chlorantraniliprole 18.5 SC, emamectin benzoate 5 SG and fipronil 5 SC were found most effective. The insecticides viz., novaluron 10 EC, acephate 75 SP and malathion 50 EC were found moderate effective, while botanicals (azadirachtin 0.15 EC and NSKE 5%) were found least effective. The maximum fruit yield was obtained in treatments of flubendiamide 48 SC, followed by chlorantraniliprole 18.5 SC, emamectin benzoate 5 SG and fipronil 5 SC. The higher fruit yield was also obtained in the treatment of novaluron 10 EC, acephate 75 SP and malathion 50 EC and minimum was obtained in azadirachtin 0.15 EC and NSKE 5 percent. The maximum net profit was obtained in the treatment of flubendiamide, followed by chlorantraniliprole, emamectin benzoate and fipronil and minimum was in azadirachtin 0.15 EC and NSKE 5 percent. The maximum B:C ratio was obtained in the treatment of malathion and acephate while, it was minimum in emamectin benzoate and novaluron.
