Abstract

The present investigation entitled ‘‘Evaluation of novel insecticides against mustard aphid Lipaphis erysimi Kalt.’’ at Student Instructional Farm (SIF), C.S.A University of Agri. & Tech. Kanpur during Rabi season of 2019-2020 & 2020-2021. The data analysis for management of mustard aphid Lipaphis erysimi Kalt. revealed a similar trend in both the years. The treatment Dimethoate 30 EC(1ml/lt) was proved significantly superior over all treatments with highest control over mustard aphid Lipaphis erysimi Kalt population in both the years. The treatment Beauveria bassiana (2g/lt) was found poorest with minimum control of mustard aphid Lipaphis erysimi Kalt population in terms of efficacy in both the years. The trend of efficacy of different treatments against mustard aphid Lipaphis erysimi Kalt were in descending order as following Dimethoate 30 EC(1ml/lt) > Imidacloprid 17.8 SL (0.25 ml/lt) > Thiamethoxam 25 WG (0.20g/lt) > Acetamiprid 20 SP (0.1g/lt) > Clothianidine 50 WDG (0.12g/lt) >Verticillium lecanii (2g/lt) > Azadirachtin 3000 ppm (5ml/lt) >Beauveria bassiana (2g/lt).

Conclusion

The results with pooled data analysis for management of mustard aphid Lipaphis erysimi Kalt. revealed a similar trend in whole study period for both the years i.e. 2019-2020 & 2020-2021 (Table 5 & 6). Dimethoate 30 EC(1ml/lt) was proved significantly superior over all treatments with highest manage of mustard aphid Lipaphis erysimi Kalt population in both the years. Beauveria bassiana (2g/lt) was found poorest with minimum control of mustard aphid Lipaphis erysimi Kalt population in terms of efficacy in both the years. The trend of efficacy of different treatments against mustard aphid Lipaphis erysimi Kalt were in descending order as following Dimethoate 30 EC(1ml/lt) > Imidacloprid 17.8 SL (0.25 ml/lt) > Thiamethoxam 25 WG (0.20g/lt) > Acetamiprid 20 SP (0.1g/lt) > Clothianidine 50 WDG (0.12g/lt) >Verticillium lecanii (2g/lt) > Azadirachtin 3000 ppm (5ml/lt) >Beauveria bassiana (2g/lt).
