A field experiment was conducted between the agricultural seasons of 2022 and 2023. Neem (Azadirachta indica L.) oil 0.03% 5ml/lit is one of seven plant products. 5% seed kernel extract of neem (Azadirachta indica L.) @ 6ml/lit. 5ml Karanj (Pongamia pinnata L.) oil per lit. Nimbecidine 0.03% at 4ml/lit, Achook 0.03% at 3ml/lit, Neem gold 0.15% at 2ml/lit, and Nimastin 0.15% at 2ml/lit were tested against vector activity to lower the prevalence of mosaic disease. The treatment T2 with two sprayings of neem seed kernel extract 5% @ 5ml /lit. at ten-day intervals had the lowest disease incidence (23.45%) and the highest fruit output (64.45 q/ha) during the Rabi, 2022-23 cropping season. Control has the highest disease incidence (35.45%). The mosaic disease of the chilli has a detrimental impact on yield contributing qualities during Rabi season.
