Banded leaf and sheath blight of maize - its epidemiology and management

By: Contributor(s): Material type: TextTextPublication details: Kathmandu (Nepal) NARC|CIMMYT : 2002Description: p. 108-112ISBN:

Subject(s): DDC classification:
  • 631.536 RAJ
Summary: Banded leaf and sheath blight incited by Rhizoctonia solani f.sp. sasakii Exner. has become an increasingly severe and economically important disease of maize in several countries of Asia. The occurrence of the disease has also been reported from other parts of the world. The disease is favoured by hot and humid conditions. Efforts to manage the disease through chemicals have not been successful. Stripping of lower 2-3 sheaths from ground level when the crop is 35-40 days old has been found to check disease spread significantly. Genetic variability for resistance has been found to be limited. Selection of disease resistance has been intensified through a collaborative project initiated by CIMMYT in collaboration with national programmes in the Asian Region. A number of CML and other materials of early and late maturity have been identified having a reasonable level of resistance. In the paper, detailed information on various aspects such as distribution, symptoms and signs, creation of artificial disease epiphytotics, factors affecting disease development and various approaches to disease management has been provided.
