Abstract: Sugarcane is affected by several diseases in Assam. Although the cultivation area of sugarcane in Assam is less as a comparison to other sugarcane growing states of India, the prevalence of different diseases caused a reduction in yield potential of the crop.

Red rot caused by Colletotrichum falcatum was found to occurs upto percent disease incidence of 10.53%. Wilt caused by Fusarium sachhari was found to occour upto percent disease incidence of 19.23%. Diseases like pokkah boeng, Yellow leaf disease (YLD) are becoming to be a major disease in Assam.
