Abstract

Silicon can reduce levels of several important diseases of rice, including blast brown spot, sheath blight, leaf scald and grain discoloration. Levels of control are equal to that achieved by fungicides for disease such as blast and brown spot. Hence, the number of fungicide applications and rates can be reduced significantly. Residual activity of silicon was effective for disease control in the second year crop and was comparable to a first year silicon application or a full rate of a fungicide. Silicon enhanced performance of partially-resistant cultivars so that they were comparable to highly resistant cultivars for both blasts and sheath blight. These findings suggest that silicon could be employed in integrated disease management systems for reducing fungicide use and enhancing host plant resistance for the control of important rice diseases worldwide. © 2001 Elsevier B.V.
