Most of commercially popular cultivars of mango are susceptible to the powdery mildew disease. White powdery growth is appearance on flowers and pea size fruits, which leading to dropping of flowers and pea size fruits cause serious fruit yield losses to the mango growers. Evaluation of different fungicides along with recommended for reduced loss due to powdery mildew. All tested fungicides were found significantly reduced disease incidence. The minimum disease intensity (6.98%) was recorded in propiconazole (0.025%) followed by difenoconazole (0.025%) and hexaconazole (0.005%), their disease intensity was reported 7.91% and 8.63%, respectively. Significantly highest fruit yield (4001 kg/h) was obtained in propiconazole (0.025%) followed by hexaconazole (0.005%) and difenoconazole (0.025%) with fruit yield of 3858 kg/h and 3758 kg/h, respectively. Maximum net return (Rs.26985/h) with ICBR (1:8.75) was obtained in propiconazole but hexaconazole gave highest ICBR (1:14.57)
