Abstract
The bio-efficacy of chlorantraniliprole, quinolphos, lamda cyhalothrin, diflubenzuron, endosulfan, triazophos and indoxacarb were evaluated against tobacco leaf eating caterpillar Spodoptera litura infesting soybean. The soybean was sprayed twice with respective insecticides at 10 days interval starting from 35 days after germination. The experimental studies revealed that, the larval population of leaf eating caterpillar was significantly reduced by the treatment of quinolphos 25 EC @ 1000 ml.ha-1 followed by endosulfan 35 EC @ 1000 ml.ha-1 and lambda cyhalothrin 5 EC @ 300 ml.ha-1, which were at par with each other. Highest yield was recorded with the treatment of lambda cyhalothrin 5 EC @ 300 ml ha-1 (2500 kg.ha-1) followed by triazophos 40 EC @ 800 ml.ha-1 (2451 kg.ha-1), diflubenzuron 25 WP @ 400 g.ha-1 (2400 kg.ha-1).
