The plot treated by Imidacloprid provide the best Cost benefit ratio (1:7.83) followed by Thiamethoxam 25 WG 100 g/ha (1:7.59) Fipronil (1:6.66), Cartap hydrochloride (1:5.59), Beauveria bassiana 2 × 10 9 c.f.u./gm (1:4.65), Lambda cyhalothrin 5 EC 500 ml/ha (1:4.39), Metarhizium anisopliae 4.7 × 10 8 c.f.u./gm (1:3.83) and Verticellium lacani 2 × 10 8 c.f.u./ml (1:2.55).Īnonymous (2010) Monitoring of pest species and their natural enemies. and in bio-pesticides Metarhizium anisopliae 4.7 × 10 8 c.f.u./gm 2.5 kg/ha.gave the best result among all bio-pesticides. The next effective treatment was Fipronil 5 SC 1000 ml/ha followed by Thiamethoxam 25 WG 100 g/ha. The observations revealed that all the treatments were found significantly superior over untreated control, Imidacloprid 17.8 SC 200 ml/ha were found most effective in comparison to all other treatments. The data observed after 3, 7 and days after spray. All the given treatment was applied on this pest. The experiment was based on the management of Brown plant hopper, important pest of rice.
