Bio-efficacy of eco-friendly insecticides against pests of Indian bean, Lablab purpureus L.

Abstract

This paper presents the results of field studies conducted in Gujarat, India, in 2010-11, to evaluate some eco-friendly insecticides (Beauveria bassiana, Lecanicillium lecanii, Metarhizium anisopliae, Nomuraea rileyi, neem seed kernel extract, neem leaf extract, neem oil, spinosad and emamectin) in the control of insect pests (Aphis craccivora, Empoasca kerri and Bemisia tabaci) of Indian bean (Lablab purpureus) cv. Gujarat papdi-1. It was shown that the application of neem seed kernel extract and neem leaf extract were effective against sucking pests, whereas emamectin and spinosad were effective against pod borer infesting Indian bean. The maximum incremental cost benefit ratio was found in the neem seed kernel extract treatment, followed by the neem leaf extract treatment compared to all the other treatments.
