Ramularia Leaf Spot (Ramularia carthami)

Nature of Damage: More prevalent in irrigated areas of Western Maharashtra and transitional belt of Karnataka. Round and regular spots of 100 mm or more in diameter occur on both sides of leaves, whitish dense mass of conidia remain at the centre which reflects light, dry spots are brown in colour.
Cultural Control: Seed the crop at the recommended time. Avoid growing in low-lying areas and flooding under irrigation. Avoid continuous growing of safflower. Remove and destroy the diseased plants. Do not delay irrigation until the crop exhibits moisture stress symptoms.
Chemical Control: Spray mancozeb (0.25%) immediately after disease is noticed and repeat the spray 15 days later depending upon the intensity of disease.
