Studies on spray schedule of dithane M-45 and blitox against early blight of potato

Field trials during 1978–79 and 1979–80 demonstrated that 3 sprays of Dithane M-45 at 0.5% concentration and 200 lit./acre at 10 days intervals proved most effective and economical against early blight of potato. Dithane M-45 appeared more effective than Blitox in controlling this disease in all the trails.
