ESTATE CROPS NEWS – There were more than 30 diseases have been recorded since sugarcane grown for sugar in Indonesia. And yet, only few diseases considered as major diaseases since they decreased productivity up to 20% and sugar content significantly. They were: sereh caused by Phytoplasm, pokkah boeng caused by Fusarium moniliformae, leafscald caused by Xanthomonas albineans, smut caused by Sporisorium scitamineum, ratoon stunting caused by Leifsonia xyli sub sp xyli, root and basal stem rot by Xylaria warbugii, mosaic, and streak mosaic caused by virus.

The most effective controls of sugarcane disease were the use of resistant varieties, healthy seed, and quarantine. At the moment smut and streak mosaic have not effectively controlled and tend to increase their occurrence and distribution. the This paper reviews the development of important diseases which have significantly reduced sugarcane production since sugarcane commercially cultivated in Indonesia and integrated disease control strategies to support the sustainability of sugarcane industry.
