A two years study on the comparative efficacy of Neem Oil at different concentration i.e. 2%, 4% and 6% was carried out a Faisalabad during 1994 and 1995 on sugarcane variety BL-4. The data during 1994 and 1995 revealed that minimum sugarcane borers infestation 5.85 and 4.51% with maximum stripped cane yield 501.73 and 484.33 quintal/acre was recorded where Neem Oil 6% concentration was applied followed by 7.67 and 5.96% borers infestation with stripped cane yield 425.38 and 395.71 quintal per acre where Neem Oil 4% concentration was applied. In check treatment sugarcane borers infestation 10.70 and 12.62% with stripped cane yield 353.47 and 306.75 quintal per acre was recorded during 1994 and 1995 respectively. However, Neem Oil 6% concentration was found better than other treatments regarding infestation and sugarcane yield.
