花生病毒病是目前严重影响河北省花生生产的主要常发性病害。在症状上主要有轻斑驳、黄花叶和普通花叶三种类型、系分别由花生轻斑驳病毒PMMV黄瓜花叶病毒CA株系CMV-CA和花生矮化病毒PSV侵染所致,PMMV还可分别与CMV-CA或PSV形成复合侵染。轻斑驳在全省各花生产区普遍发生,发病率高且年际间变化小,黄花叶和普通花叶仅在部分地区有发生,发病率在年际间变化比较大。黄花叶和普通花叶引起的产量损失在轻重两个发生年测定结果的平均值分别为38.1％和47.5％,轻斑驳症状表现较轻,对花生生育的影响较小,因此应将两种花叶病毒病作为综合防治的重点。
Peanut virus disease is the main perennial disease that seriously affects peanut production in Hebei Province. The symptoms are mainly light mottled, yellow mosaic and common mosaic of three types, respectively, by the peanut mild mottle virus PMMV cucumber mosaic virus CM strain CMV-CA and peanut dwarf virus PSV infection caused by PMMV also Respectively, and CMV-CA or PSV form a composite infection. Light mottling occurred in all flower production areas in the province, the incidence rate is high and the inter-annual change is small, yellow mosaic flowers and ordinary flowers only occur in some areas, the incidence of changes in the relatively large interannual. The average yield loss caused by yellow flower leaf and common mosaic flower was 38.1% and 47.5% in both years of light and heavy weight respectively. The light mottling symptom was mild and had little effect on the growth of peanut. Therefore, Leaf virus disease as a comprehensive prevention and control of the focus.
