甘蔗梢腐病主要发生在甘蔗梢头部份。嫩叶基部呈现黄白色大斑,之后斑上显现细小褐色条纹,逐渐相融成大的斑条,同时沿叶脉扩张,纵裂。病叶片扭曲变形、皱褶。梢头叶片扭缠在一起,叶片基部的病痕向下蔓延至梢头时,纵剖被害蔗梢,生长点有许多长短不一的褐条纵裂,发病严重时梢头部腐烂,整株甘蔗死亡。 Sugarcane shoot rot occurs mainly in the cane tip. Young leaves at the base of a large yellow-white spot, after the spot showed small brown stripes, gradually blending into large stripes, along the vein dilation, longitudinal split. Diseased leaves distorted, wrinkled.
