花生锈病是一种流行性病害,蔓延快,为害大。该病发现于1880年。1950至1960年虽在拉丁美洲和北美洲普遍发生,而流行仅局限在西印度群岛。到1970年至1973年此病迅速扩展,目前已蔓延至几十个国家。近年来我国亦有十多个省发生此病,以广东、福建、广西等省为害较重。造成病害迅速蔓延的原因,据报道,可能是由于目前大面积推广品种的抗锈性较差,另因有些抗病品种由于病原菌生理小种的改变而失去抗性有关。因而,国内、外都在积极寻找
Peanut rust is an epidemic disease, spread quickly, harmful to the large. The disease was found in 1880. Although prevalence was found in Latin America and North America between 1950 and 1960, prevalence was only found in the West Indies. The disease expanded rapidly from 1970 to 1973 and has now spread to dozens of countries. In recent years, there are also more than 10 provinces in our country, with heavier injuries in Guangdong, Fujian and Guangxi provinces. The reasons for the rapid spread of the disease are reportedly due to the poor rust resistance of the large-scale popularization varieties and the loss of resistance due to the change of physiological races of some pathogen-resistant cultivars. Therefore, both at home and abroad are actively looking for
