本文首次明确甘蔗褪绿线条病(Sugarcane chlorotic streak)普遍存在于我国福建、广西和云南蔗区,局部地区的部分品种的发病率甚高。该病发病初期,叶片上产生正反两面形状相同的淡黄色褪绿条纹,后条纹可发展或愈合成长条纹。条纹中间部分坏死,呈淡褐色或灰白色,严重时叶片枯死。条纹可出现在叶片的中间、边缘或顶部。病株还可见有可逆性萎蔫现象。该病可由病株的蔗茎和病土传播,但不由病叶汁液、甘蔗黄蚜(Aphis sacchari)、甘蔗粉蚧(Saccharicoccus sacchari)和甘蔗扁角飞虱(Perkinsiellasaccharicida)传播。
This article first clarified that sugarcane chlorotic streak is common in sugarcane fields in Fujian, Guangxi and Yunnan in China. The incidence of some species in some areas is very high. Early onset of the disease, both sides of the leaves produce the same shape of yellowish pale green stripes, the stripe can develop or heal growth stripes. Streaks in the middle part of the necrosis, pale brown or gray, severe leaves withered. Streaks may appear at the middle, edge or top of the blade. The diseased plants also show reversible wilting phenomenon. The disease can be transmitted by the cane stems and soil of the diseased plants, but not by diseased leaf juice, Aphis sacchari, Saccharicoccus sacchari and Perkinsiellasaccharicida.
