Initial Diagnosis of Barley Rust Disease Based on Visual and Morphological Signs

Barley is among the widely distributed and commercially necessary cereals in the world. However, diseases triggered by different kinds of plant pathogens pose a serious challenge to barley production. Some of these diseases are the rusts that are caused by various fungi belonging to the Puccinia species. The main characteristic of the rust disease in barley is its wide distribution and the fact that it leads to crop losses. Early detection of the rust disease is important for its management and containment. The presented article examines the possibilities of initial diagnosis of rust disease in barley plants based on visual and morphological indicators. The morphological characteristics of the pathogen, the color, shape, and location of the blotches, and the symptoms observed on the leaf surface of barley samples infected with rust disease were analysed during the study. The findings suggest that visual and morphological indicators can be employed as an effective and practical method for the early detection of rust disease in initial diagnostics. This method enables the implementation of operational decisions in the field, thereby reducing crop losses.
