Banded leaf and sheath blight of maize caused by Hypochonus sasakii is one of the most widespread and destructive diseases of maize due to its wide host range and adaptability in Southeast Asian countries. The disease manifests on leaves, leaf sheaths, stalks lesions or rind spotting resulting in stem breakage, clumping and cracking of styles and ear rot, etc., resulting in cent per cent yield loss and lodging in severe conditions Pantnagar is one of the hot spots for this disease and studies have been carried out at this location for the last 25 years on epidemiology, pathogen variability, and disease management using chemicals, cultural practices, and bio-control agents (including evaluation of maize genotype for resistance sources). Studies carried out with respect to chemicals only (Tilt (Propocanozole)) showed some effectiveness. Cultural practices do not fit in normal recommended technology of maize production. Use of bio-control agents opens up a new era for management. But in this case use of T. harzianum, a common bio-agent, exhibited a synergistic effect on ear rot development. Some newer bio-agents are in the experimental stage. Another new chemical, Divident 3 WS (Diphenoconazole), is being also tested. Few inbred lines/genotypes have also been identified which are under confirmation for use in a resistant breeding program. A set of experiments is also in execution for use of integrated approaches to manage the banded leaf and sheath blight.
