The results revealed that applying of neem oil @ 3.0 m/l of water at three days interval showed better performance in respect to control of Fruit borer in Tomato than the other treatments. The highest number of total fruit per plant (33.20), number of healthy fruit per plant (32.44) as well as the lowest number of infested fruit (0.17) was obtained when the crop was treated with neem oil @ 3.0 m/l of water at three days interval. The highest yield (66.80 tones) was recorded when the crop was treated with neem oil @ 3.0 m/l of water at three days interval.
