Bio – efficacy of some newer insecticides against brinjal shoot and fruit borer Leucinodesorbonalis (Guen.)

Author(s): Surya Prakash Gupta and SP Singh
Abstract: Bio-efficacy of six newer insecticides – emamectin benzoate (15 g a.i. ha-1), imidacloprid (20 g a.i. ha-1), indoxacarb (50 g a.i. ha-1), lambda – cyhalothrin (15 g a.i. ha-1) and spinosad (50 g a.i. ha-1) along with quinalphos (250 g a.i. ha-1) was evaluated against shoot and fruit borer (Leucinodesorbonalis Guen.) in brinjal (Solanummelongena Linn) at Rajendra Agricultural University, Pusa, Bihar during Rabi 2012-13. Spinosad treatment was significantly superior to others and at par with emamectin benzoate in reducing the shoot and fruit borer damage. Spinosad at 50 g a.i. ha-1 recorded the maximum fruit yield (280.42 q ha-1). It was followed by emamectin benzoate at15 g a.i. ha-1 (267.74 q ha-1) and indoxacarb at 50 g a.i. ha-1 (262.58 q ha-1). Lambda - cyhalothrin 15 g a.i. ha-1 treatment recorded maximum cost: benefit ratio of 1: 4.23 closely followed by imidacloprid 20 g and quinalphos 250 g a.i. ha-1 with ICBR of 1: 3.71 and 1: 3.43, respectively.
