Abstract:
The current investigation, which is, "Study on incidence of insect pest complex of brinjal, Solanum melongena L. and evaluation of insecticides against shoot and fruit borer, Leucinodes orbonalis Guenee” was carried out in the experimental field Agriculture Research Farm, Faculty of Agriculture, Rabindranath Tagore University, Raisen (M.P.) during Rabi 2020-21 and 2021-22. In 2020-21, insecticide spinosad 45 SC @ was founded most superior insecticide and recorded least fruit infestation as 11.64, 11.64, 13.86 and 16.09% at 3^rd, 5^th, 7^th and 10^th DAS after first spray. In 2020-21, after second spray, spinosad 45 SC @ was founded again most superior insecticide and recorded least fruit infestation as 7.12, 9.90, 12.68 and 12.68% at 3^rd, 5^th, 7^th and 10^th DAS. The maximum fruit infestation reduction (80.10% & 85.65%) was recorded from spinosad 45 SC treated plots during respective years. In 2021-22, insecticide spinosad 45 SC @ was founded most superior insecticide and recorded least mean fruit infestation as 14.52 and 12.96% after first and second spray. In 2021-22, the maximum fruit infestation reduction (80.31 & 84.05%) was recorded from spinosad 45 SC treated plots during 2020-21 & 2021-2022. In 2020-21, the maximum increased yield (97.78 q/ha) and net profit values (Rs. 76565.65) were obtained from spinosad 45 SC @ 0.5 ml/l treated plots. In 2021-22, the maximum fruit yield, increased yield and net profit values over control was recorded from spinosad45 SC @ 0.5 ml/l treated plots with 215.3 q/ha, 99.5 q/ha and Rs. 67325.5. The maximum incremental cost benefit ratio was recorded from emamectin benzoate 5 SG during both the years.
