Among various eco-friendly pesticides, azadirachtin 10,000 ppm 0.002 percent was the most effective treatment as it recorded lowest infestation of lepidopteran pests viz., gall forming black caterpillar (4.80 galls/ 25 twigs) and leaf rolling caterpillar (5.00% leaflet damage) and also recorded with highest fruit yield (73.41 q/ha) and protection cost-benefit ratio (1:11.18).
