A study was conducted to determine the effect of fungicide treatment (Dithane 33 F : 0.05, 0.10, 0.15, 0.20, and 0,25 percent) for controling P. infestants on potato var. Granola. Dithane M45 was used as standard. Randomized Block Design with four replications was used in this experiment. The best treatments for controlling late blight are Dithane 33 F (0.25 percent and Dithane M45 (0.2 percent). The second is Dithane 33 F (0.15 percent). The highest yield were given by Dithane 33 F (0.20 percent and 0.15 percent) and Dithane M45 (0.2 percent)
