Effect of botanical extracts against shoot and fruit borer, Earias vittella (Fab.) on bhendi under in vitro condition

Abstract

The antifeedant and mortality effects of eight plant extracts viz., neem leaf (5%), Calotropis leaf (5%), neem seed kernel (5%), Datura leaf (5%), oleander seed (5%), garlic bulb (5%), garlic + chilli extracts (5%) were evaluated against bhendi shoot and fruit borer, Earias vittella F. under the laboratory conditions. The results showed that neem leaf extract and neem seed kernel extract exhibited maximum antifeedant activity after 24 hours of treatment. The highest per cent mortality was observed with neem seed kernel extract followed by garlic + chilli extracts, neem leaf extract and oleander seed extract. The data demonstrated that these botanical extracts have potential for the effective management of E. vittella on bhendi.
