The insect pest population in sapota have proliferated across a greater region due to intense production, monoculture of the cultivars like Kalipatti and Cricket Ball, changing environmental conditions, and unmanaged pest. Among various insect pests, the sapota bud borer Achrasella achrasella Bradley causes significant damage to flower buds and fruits of sapota by boring into unopened flower buds and feeding on the corolla and gynoecium and finally reduces the marketable yield. The yield loss is seen to the extent of 15 per cent. Thus, the study was conducted to manage this pest using newer molecules and botanical insecticides at Kittur Rani Channamma College of Horticulture, Arabhavi, University of Horticultural Sciences, Bagalkot, Karnataka, India during the year 2021 to 2022. Among the chemicals, Chlorantraniliprole 18.5 SC @ 0.4 ml/l, Flubendiamide 39.35 SC @ 0.2 ml/l and Emamectin benzoate 5 SG @ 0.3 g/l were most promising with 5.24, 5.85 and 5.90 per cent bud damage, respectively and all three were statistically on par with each other. The next best treatment was Deltamethrin 2.8 EC @ 2 ml/l (6.52%), which was on par with Lambda-cyhalothrin 5 EC @ 0.5 ml/l (7.60%). This was followed by treatment of Novaluron 10 EC @ 0.75 ml/l (8.77%) and Azadirachtin 3000 ppm (15.40%).
