Abstract
Sheath Blight Disease of Rice (Rhizoctonia solani Kuhn): Problems and Prospects of
Various Disease Control Measures in Indonesia. H. Punvanti, M.K. Kardin, A. Nasution, and Sutoyo. Sheath blight caused by Rhizoctonia solani Kuhn is one of the most important diseases of rice in Indonesia. Damage increases due to the wide spread cultivation of modern high yielding rice varieties which are susceptible to the pathogen and the adoption of new technologies such as close spacing and high application of nitrogen fertilizer, which are suitable for the development of the disease. So far, no resistant rice variety is available. Biological control using antagonistic microbes
has been explored, although still at green house and limited field experiments. Sanitation and proper use of nitrogen fertilizer are recommended to minimize damage by sheath blight disease. Several fungicides are effective to control the pathogen, but due to the environment concerns and low economic value of rice, chemical control should be used as the last resort, in the future, cultivation of transgenic plants inserted with chitinase gene(s) might help to improve disease management of sheath blight of rice.
