Abstract
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.This publication has 0 references indexed in Scilit:
