高粱黑束病(Acremonium strittum W.Gams)是我国高粱上的一种新病害。据报道其病原菌(Acremonium strictum W.Gams=Cephalosporinm acremonium Cda.)能侵染多种单子叶和双子叶作物,如高粱、玉米、燕麦、棉花等,及一些杂草。1979年 EL-shafey等在埃及报道发生此病。1982年 Frederiksen等报道美国也有此病发生。随后,在阿根廷(Forbes 等1982)、委内瑞拉(Silva 等1983)及墨西哥、苏丹、洪都拉斯(Frederiksen1984)等国也先后有高粱黑束病发生的报道。Natural 等(1982)的试验表明该病能造成50%的减产。1992年我们在辽宁省、吉林省、黑龙江省农科院高粱试验田中发现了此病,通过病害诊断试验确认是高粱黑枣病。高粱黑束病是一种维管束病害。在叶片上症状为叶脉上有褐色条斑,多沿主脉一侧或两
Acremonium stridentum W.Gams is a new disease on sorghum in China. Its pathogen (Acremonium strictum W. Gams = Cephalosporinm acremonium Cda.) Has been reported to infect a variety of monocotyledonous and dicotyledonous crops such as sorghum, corn, oats, cotton, and some weeds. In 1979, EL-Shafey et al reported the disease in Egypt. In 1982, Frederiksen et al reported that the United States also had this disease. Subsequently, reports of black beam disease in sorghum have also been reported in countries such as Argentina (Forbes et al. 1982), Venezuela (Silva et al 1983) and Mexico, Sudan and Honduras (Frederiksen 1984). Natural et al. (1982) showed that the disease caused a 50% reduction in production. In 1992 we found the disease in Liaoning Province, Jilin Province, Heilongjiang Academy of Agricultural Sciences sorghum trial field, through the disease diagnosis test confirmed that the sorghum jujube disease. Black sorghum is a vascular disease. Symptoms on the leaves are brown streaks on the veins, mostly along one or both of the main veins
