Rhizoctonia solani f.sp. Sasakii Inciting Banded Leaf and Sheath Blight of Maize and their Management: An Overview

Abstract

Banded leaf and Sheath blight of maize caused by Rhizoctonia solani f.sp. Sasakii [teleomorph: Thanatephorus cucumeris] is of worldwide occurrence and is known to cause substantial yield losses. It is a major production constraint in high yielding varieties under intensive maize production systems. The pathogen has a very wide host range and exhibits considerable pathogenic and molecular variability. Due to non-availability of highly resistant cultivars, the management of banded leaf and sheath blight primarily relies on chemical control. However, the disease can be managed effectively through integration of effective cultural practices, botanical pesticides, bio-control agents and fungi toxicants. In this review article, the information available on various aspects of this disease has been presented and discussed along with strategies for disease management.
