大麦条锈病的流行是由条锈菌引起的。sp. hordei race 24及其变种于1975年在波哥大附近开始。到1982年，几乎影响了南美洲所有的商业大麦[Hordeum vulgare]地区。理论上病原体是外来的。根据年份和国家的不同，安第斯国家的产量损失估计为30-70%。欧洲和最近发布的安第斯大麦品种进行了测试的抗性，而北美品种是非常敏感的病原体。
Epidemics of barley stripe rust, shown to be caused by Puccinia striiformis f. sp. hordei race 24 and its variants started in 1975 near Bogota. Colombia, and affected nearly all commercial barley [Hordeum vulgare] areas in South America by 1982. The pathogen is theorized to be exotic. Yield losses of 30-70% were estimated in the Andean countries, depending on year and country. European and recently released Andean barley cultivars tested were resistant, whereas North American cultivars were highly susceptible to the pathogen.
