Why farmers need to monitor yellow rust

摘要

The surge in yellow rust is becoming a bigger challenge for agronomists and farmers. The disease takes its name from the highly visible parallel lines of yellow-orange pustules that are produced along the leaves of adult plants.New races of the pathogen and unexpected infections on previously resistant varieties have caused well-documented control difficulties in the field, with growers being warned to "expect the unexpected" from such a highly diverse pathogen.
