Bio-efficacy of Lambda Cyhalothrin against Nliaparvata lugens (Stal.) and Safety to Green Mirid Bug

A field trial was conducted to evaluate lambda cyhalothrin, new capsule suspension formulation, indicated that lambda cyhalothrin applied at 50, 25 and 12.5 g a.i. ha⁻¹ were more effective against brown plant hoppers as compared to the standard checks. In terms of cumulative reduction of pest incidence, lambda cyhalothrin treatments were found to be superior to the standard checks. Lambda cyhalothrin at 50 and 25 g a.i. ha⁻¹ were slightly harmful to the green mirid bugs in the rice ecosystem. Lambda cyhalothrin at 12.5 g a.i. ha⁻¹ exhibited significant pest control and also not harmful to the natural enemy. Hence, this dose can be recommended for the brown plant hopper management in rice.
