Abstract

The experiment was carried out at Research farm of BTC CARS, Bilaspur during Rabi 2019-20. A field experiment was laid down in randomized block design (RBD) with six bio-pesticides and botanicals one insecticide and an untreated control. Bio-pesticides do not have harmful affect against bio-agents. The insecticide Imidacloprid 17.8 SL @ 0.2ml/liter was found to be most effective treatment against mustard web worm and it was recorded least over all mean population (3.29 larvae/plant) with maximum larval reduction per cent (72.16) followed by Garlic extract 5% @ 50 ml/lit, recorded with 3.61 over all mean population and 69.46 per cent reduction in web worm population whereas Beauveria bassiana 10 % WP (1 × 109CFU/gm) @ 10 g/lit. was recorded with 3.83 larvae/plant, 67.59 cent reduction in population while other treatments viz Metarhizium anisopliae 10% WP (1 × 109 CFU/gm) @ 10g/lit. , Lecanicillium lecanii 10% WP (1 × 109 CFU/gm) @ 10 g/lit, Aak leaf extract 5% @ 50 ml/lit. and A

Keywords

Crocidolomia binotais (Zell.), bio-pesticide and botanical-agents.

Conclusion

The results show that biopesticides of mustard crops Imidachloprid, Beauveria bassiana, Garlic (Allium sativam L.) extracts 5%, and Aak (Calotropis sp. L.) Leaf extract 5% web worm control is an effective biopesticides and obtaining a higher yield and economic return. Thus biopesticides of mustard with an effective production in Bilaspur as well as in other developing state that have similar socio-economic backgrounds.
