Efficacy of botanicals and bio-pesticides against shoot and fruit borer in Brinjal

Abstract

The present investigation was undertaken to find the efficacy of botanicals and biopesticides against brinjal shoot and fruit borer during kharif 2019-2020 at the Research farm, JNKVV, College of Agriculture, Tikamgarh (M.P.). The experiment consists nine treatments viz., Neem oil 1% (T1), Karanj oil 1% (T2), Beauveria bassiana 1× 1012 spores/ml (T3), Metarrhizium anisopliae 1× 1012 spores/ml (T4), Neem oil- Bb- Neem oil (T5), Neem oil – Ma –Neem oil (T6), Karanj oil –Bb –Karanj oil (T7), Karanj oil –Ma-Karanj oil (T8) and Untreated control (T9). The results revealed that Neem oil 1% proved to be most effective in controlling the population of brinjal shoot and fruit borer by recording minimum shoot and fruit infestation of 5.80 and 6.65% respectively followed by Neem oil-Ma-Neem oil. However, Karanj oil 1% proved to be least effective. The highest net profit and cost benefit ratio was observed from the plot treated with Neem oil 1% (Rs 46860/ha and 1:26.0) followed by Neem oil- Ma -eem oil (Rs 42770/ha and 1:25.3). The maximum fruit yield of 237.33 q/ha was recorded with the application of Neem oil 1% which was 25.79% higher than the control. Other treatments gave yield ranging from 217 – 233.33 q/ha.
