Proceedings of an international workshop held at CIMMYT p. 59-62Summary: A large number of leaf blight affected wheat samples were received/collected in every cropping season during 1988-1996, from different coordinating centers in India and neighboring countries. After repeated solations Bipolaris sorokiniana, Helminthosporium spiciferum, Pyrenophora tritici-repentis, Alternaria alternata, A. triticina, and Curvularia lunata were found associated with foliar blight each year. Of these, all isolates of B. sorokiniana and A. triticina were pathogenic. Bipolaris sorokiniana is the predominant leaf blight pathogen in the Indian states of Bihar, Delhi, Gujarat, Haryana, Karnataka, Maharashtra, Rajasthan, Uttar Pradesh, and West Bengal, and neighboring countries of Bangladesh and Nepal. Alternaria triticina predominates in the states of Himachal Pradesh, Punjab, Jammu and Kashmir, and Madhya Pradesh. Maximum disease development is promoted by temperatures around 28ºC and relative humidity of 92% at heading and flowering of the crop. Yield loss due to leaf blight is estimated at 18-22%. Application of fungicides Tilt 25 EC (0.5 L ha-1) and Indofil M-45 (2.5 kg ha-1) achieved satisfactory disease control.Collection: CIMMYT Publications Collection
