Adjusting fungicide treatment programmes when resistance is developing: the case of spot‐form net‐blotch in Western Australia

Plant Pathology, 2023
Abstract We use the case of spot‐form net‐blotch (SFNB) and azole fungicides in Western Australia to investigate the financial implications of a switch from fungicide A, to which high resistance is developing, to a more expensive fungicide B, to which less resistance has developed.

Virulence Spectra of Hungarian Pyrenophora teres f. teres Isolates Collected from Experimental Fields Show Continuous Variation without Specific Isolate × Barley Differential Interactions [PDF]

Journal of Fungi
Pyrenophora teres f. teres (Ptt), the causal agent of net form net blotch (NFNB) disease, is an important and widespread pathogen of barley. This study aimed to quantify and characterize the virulence of Ptt isolates collected from experimental fields of

Identification of quantitative trait loci associated with resistance to net form net blotch in a collection of Nordic barley germplasm

Theoretical and Applied Genetics, 2017
Association mapping of resistance to Pyrenophora teres f. teres in a collection of Nordic barley germplasm at different developmental stages revealed 13 quantitative loci with mostly small effects. Net blotch, caused by the necrotrophic fungus Pyrenophora teres, is one of the major diseases in barley in Norway causing quantitative and qualitative yield

Adult‐plant resistance to net form net blotch in barley (Hordeum vulgare L.): Durability and genetic control

Plant Breeding
The research reported here was conducted to follow up on observations of durable adult‐plant resistance to net form net blotch in several Australian varieties of barley (Hordeum vulgare L.). Over 11 years, isolates of Pyrenophora teres f.

Genome-Wide Association Study of Spot Form of Net Blotch Resistance in the Upper Midwest Barley Breeding Programs [PDF]

Phytopathology®, 2017
Pyrenophora teres f. maculata, the causal agent of spot form of net blotch (SFNB), is an emerging pathogen of barley in the United States and Australia. Compared with net form of net blotch (NFNB), less is known in the U.S. Upper Midwest barley breeding programs about host resistance and quantitative trait loci (QTL) associated with SFNB in breeding ...

Genetic analysis of net form net blotch resistance in barley lines CIho 5791 and Tifang against a global collection of P. teres f. teres isolates [PDF]

Theoretical and Applied Genetics, 2016
A CIho 5791 × Tifang recombinant inbred mapping population was developed and used to identify major dominant resistance genes on barley chromosomes 6H and 3H in CI5791 and on 3H in Tifang. The barley line CIho 5791 confers high levels of resistance to Pyrenophora teres f.

Rpt5 encodes a receptor-like protein that provides broad and effective net form net blotch (Pyrenophora teres f. teres) resistance in barley

bioRxiv
The foliar disease net form net blotch (NFNB), caused by the necrotrophic fungal pathogen Pyrenophora teres f. teres (Ptt), causes significant yield and quality losses of barley worldwide. Dominant resistance conferred by the Resistance to Pyrenophora teres 5 (Rpt5) gene from barley line CI5791 is the broadest and most effective resistance reported in ...

Analysis of polymorphism of microsatellite markers linked to a longterm net form of net blotch resistance gene in winter barley varieties in the south of Russia [PDF]

The Indian Journal of Genetics and Plant Breeding (The), 2018
Net form of net blotch (NFNT) is the most dangerous and devastating disease of barley causing huge losses in Russia. Highly effective gene rpt 5 determining resistance to net blotch pathogen in Russia was used in the study.

Development of Expressed Sequence Tag (EST)–based Markers for Genomic Analysis of a Barley 6H Region Harboring Multiple Net Form Net Blotch Resistance Genes

The Plant Genome, 2010
We previously identified a region near the centromere of barley ( L.) chromosome 6H that harbors two closely linked net form net blotch resistance genes ( and ).

Emergence and spread of the barley net blotch pathogen coincided with crop domestication and cultivation history. [PDF]

PLoS Genetics
Fungal pathogens cause devastating disease in crops. Understanding the evolutionary origin of pathogens is essential to the prediction of future disease emergence and the potential of pathogens to disperse. The fungus Pyrenophora teres f.
