Aims: This study aims to find out the most effective newer insecticides to control shoot and fruit borer in the brinjal. Study Design: The experiment of field was carried out with randomized block design. Place and Duration of Study: The field experiment on management of brinjal shoot and fruit borer Leucinodes orbonalis (Guen.) with newer insecticides were held on during October 2018 to April 2019 at Gwalior (Madhya Pradesh). Methodology: Infestation of shoot was observed from each plot by counting the total number of plants and the plants infested by shoot and fruit borer from the beginning of shoot formation. Total number of healthy fruits and infested fruits were counted from five plants of each plot at the time of fruit picking. The weight of both type of fruits (healthy and infested) were recorded to calculate the fruit infestation by weight basis. The treatments were applied from the initiation of infestation to till the complete harvest of the crop at 15 days interval regularly. The recorded data were subjected to statistical analysis after transformation. The count data also transformed and percentage were transformed to angular values. Results: The treatment of spinosad 45 SC and indoxacarb 14.5 SC1 (suspension concentrate) were found best among all treatments with 3.42 percent and 3.58 percent shoot infestation respectively and the treatments chlorantraniliprole 18.5 SC and flubendiamide 20 WG2 were found least effective with 4.69 percent and 4.78 percent infestation of shoot respectively. Treatments spinosad 45 SC and indoxacarb 14.5 SC were significantly reduced the 3.11 percent and 3.28 percent fruit infestation respectively. Whereas the treatments flubendiamide 20 WG (Water-Dispersible Granule) and chlorantraniliprole 18.5 SC were the least effective with 4.99 percent, 4.69 percent fruit infestation, respectively. Conclusion: Among all used treatments spinosad 45 SC and indoxacarb 18.5 SC, were the most effective treatments as they recorded higher yield and higher benefit cost ratio.
