Management of Purple Blotch in Onion:-

Initially small, elliptical lesions or spots that often turn purplish-brown which are surrounded by chlorotic margin. If the spots enlarge, chlorotic margin extend above and below the actual lesion. Lesions usually girdle leaves, causing them to fall over. Lesions may also start at the tips of older leaves.

For managing the disease effectively, healthy seed should be used. Crop rotation of 2-3 years with non related crops should be followed. Spay fungicides, Mancozeb 75% WP @ 45 gm/15 litre of water or Hexaconazole 5% SC @ 20 ml/15 litre of water or Propiconazole 25% EC @ 15 ml/ 15 litre of water at 10-15 days intervals from 30 days after transplanting or as soon as disease appears.
