Host Response of Winter Wheat to the Causal Agents of Eyespot and Fungicide Resistance of the Pathogens.

ABSTRACT: Eyespot is one of the most important fungal diseases of wheat in the Czech Republic. As part of a long-term study (2015-2024), the occurrence, population structure, and pathogenic variability of Oculimacula yallundae and Oculimacula acuformis were investigated. In total, 356 O. yallundae, 24 O. acuformis, and 33 mixed cultures were collected and identified using PCR. The study also included small-plot inoculation trials (2022-2023) to assess the response of widely grown winter wheat cultivars. Disease severity was evaluated visually, pathogen DNA was quantified using qPCR, and the presence of the resistance gene Pch1 was determined with the STS marker Xorw1. In addition to these analyses, monitoring of fungicide resistance to two commonly used fung
