The leaf spots are characterized by chlorotic lesions, angular to irregular in shape, later turn grayish-brown with profuse sporulation at the centre of the spot.
Severely infected leaves drop off prematurely, resulting in reduced fruit yield.
Management
Pant Samrat variety is resistant to both the leaf spots.
Diseases can be managed by growing resistant varieties.
Spraying 1 per cent Bordeaux mixture or 2 g Copper oxychloride or 2.5 g Zineb per litre of water effectively controls leaf spots.
