花生青枯病也称花生瘟,是由花生青枯病菌引起的一种细菌性病害。病菌主要是在土壤、病残株或肥料内越冬,第二年花生生长期借雨水、人畜传播。病菌从花生根部伤口侵入繁殖使植株输导组织破坏导致茎叶枯萎死亡。花生青枯病首先形成发病中心,以后扩展蔓延乃至成片枯死,轻则减产,重则无收。花生青枯病的发生与土壤类型、种植方式、施肥和花生品种有关。 Peanut bacterial wilt, also known as peanut plague, is a bacterial disease caused by the bacterial wilt of peanuts. Germs are mainly in the soil, sick strains or fertilizer winter, the second year of peanut growth by rain, human and animal transmission. Pathogen invaded and propagated from the peanut root wound led to the destruction of the tissue-derived tissue and resulted in the wilt of the stem and leaf. First of all, peanut wilt disease centers are formed. After that, pests expand or even die, ranging from reduced output to heavy output. The occurrence of peanut bacterial wilt is related to soil types, planting methods, fertilization and peanut varieties.
