甘薯丛枝病俗称“薯公”、“藤鬼”,是由类菌原体引起的一种重要薯病。结薯前发病的不结薯,结薯后发病对产量影响亦大。主要症状是小叶、丛枝。我国台湾、广东,福建等省均有发生,受害程度不一。福建有50个县(市)发生,七十年代以来,曾多次在沿海部分县、社大面积流行成灾,引起严重减产。1982年莆田县下房、赤岐、铁炉、上林大队大面积流行,早薯发病率一般在13.6—61.6％,重的达70—80％,减产130余万斤原粮(4斤鲜薯折1斤原粮)。此病已成为当地发展甘薯生产的主要限制因素。几年来,我们在查明初侵染源、虫媒及防病措施作了分析之后,认为要迅速地控制甘薯丛枝病的危害,必须采取以农业防治为主,杜绝初侵染源为中心的一套综合防治措施,具体包括:
Sweet potato broom disease commonly known as “potato public”, “vine ghost”, is caused by a mycoplasma an important potato disease. The incidence of tuber before tubers tuber, tuber after the onset of the impact on yield is also large. The main symptoms are lobular, Congzhi. China’s Taiwan, Guangdong, Fujian and other provinces have occurred, the degree of victimization. There are 50 counties (cities) in Fujian Province. Since the 1970s, many coastal counties and communes have been causing widespread epidemic and have caused serious cuts. 1982 Putian County off the house, red Qi, iron stove, the large-scale forest fire on the unit, the incidence of early potato is generally 13.6-61.6%, weighing up to 70-80%, reducing production of more than 130 kg of raw grain (4 pounds of fresh potato Fold 1 kg of raw grain). This disease has become the main limiting factor for the local development of sweet potato production. In the past few years, after analyzing the sources of initial infection, insect vectors and disease prevention measures, we believe that to control the harmfulness of sweetpotato shoots rapidly, we must take the prevention and control of agriculture as the center and prevent the primary source of infection as the center A comprehensive set of prevention and treatment measures, including:
