Net blotch of barley (Hordeum vulgare), caused by Drechslera teres and its effect on yield

Agronomía Mesoamericana, 2022
Introduction. Barley (Hordeum vulgare) net blotch (MR) causes yield losses estimated between 23 % to 44 %, as well as its malting quality. Objective. To evaluate over time the evolution of net blotch in different malting barley cultivars with and without

Management of Pyrenophora teres f. teres, the Causal Agent of Net Form Net Blotch of Barley, in A Two-Year Field Experiment in Central Italy. [PDF]

Pathogens, 2022
Pyrenophora teres is the causal agent of barley net blotch (NB), a disease that can be found in two different forms: net form (NFNB), caused by P. teres f. teres, and spot form (SFNB), caused by P. teres f. maculata.

Protection of winter barley against net blotch using modern fungicides

Siberian Herald of Agricultural Science
The results of a three-year (2020–2022) study of the efficacy of the modern fungicide Ace, CSC of Russian production (pyraclostrobin - 80 g/l + prothioconazole - 40 g/l + tebuconazole - 160 g/l) against the pathogen of barley net blotch are presented. Barley is an important food, feed and fodder grain crop, ranking fourth in the world in terms of area ...

Genome-wide association mapping of net form net blotch resistance in barley at seedling and adult plant stages

Frontiers in Agronomy
Net form net blotch (NFNB) caused by Pyrenophora teres f. sp. teres (Ptt) is an emerging barley disease in several countries. It causes severe yield and quality losses due to infection of leaves, kernels, and stems.

Global Spread, Genetic Differentiation, and Selection of Barley Spot Form Net Blotch Isolates

Phytopathology®
Spot form net blotch, caused by Pyrenophora teres f. maculata, is a significant necrotrophic disease of barley that spread worldwide in the twentieth century. Genetic relationships were analyzed to determine the diversity, survival, and dispersal of a diverse collection of 346 isolates from Australia, Southern Africa, North America, Asia Minor, and ...

Genetic Characterization of Barley Net Blotch Resistance Genes [PDF]

Plant Disease, 2011
Net blotch, caused by Pyrenophora teres f. teres, is one of the most devastating diseases of barley (Hordeum vulgare). Efficient utilization of available resistance sources is dependent upon successful characterization of genes conditioning resistance in diverse sources. Five net-blotch-resistant parents and one susceptible parent were intercrossed to

Four Reference Quality Genome Assemblies of Pyrenophora teres f. maculata: A Resource for Studying the Barley Spot Form Net Blotch Interaction

Molecular Plant-Microbe Interactions, 2021
Pyrenophora teres is the causal agent of net blotch, the most devastating foliar disease of barley. In nature, net blotch is seen in two forms, net form net blotch, caused by P. teres f. teres, and spot form net blotch, caused by P. teres f. maculata. To
