Pyrenophora teres f. maculata, Causal Agent of Spot Form Net Blotch of Barley, Is an Emerging Pathogen of Durum Wheat.

Phytopathology
Emergent plant pathogens threaten global food security, as they evolve to infect new hosts and spread to new geographic regions. Pyrenophora teres f. maculata is a foliar pathogen of barley that is present worldwide and can cause significant yield losses.

Effects of meteorological data on the development of net blotch of spring barley in Turkey

International Service Availability Symposium
Ensuring sustainability and productivity in plant production is of paramount importance, and plant diseases represent a significant challenge in this regard. Meteorological changes due to climate change cause the dynamics of plant pathogens to change and

Efficacy of Bacillus and Pseudomonas antagonist bacteria as biocontrol agents of barley net blotch in field conditions

Siberian Herald of Agricultural Science
   Barley net blotch is a widespread disease of cereal crops worldwide, causing significant economic losses. The predominant method of controlling it remains chemical defense, which has many negative consequences.

Resistance of barley accessions from the East Asian Center of crop diversity to the net and spot forms of the net blotch pathogen

PROCEEDINGS ON APPLIED BOTANY GENETICS AND BREEDING
Background. Barley is a major fodder crop and valuable raw material for the brewing industry. A harmful disease of barley is net blotch, caused by the hemibiotrophic fungus Pyrenophora teres Drechsler, which exists in two forms that differ in symptoms

Genetic Diversity of Net Blotch Pathogens of Barley in Turkey

International Journal of Agriculture and Biology
Pyrenophora teres f. maculata (Ptm) (spot form of net blotch) and Pyrenophora teres f. teres (Ptt) (net form of net blotch) are common leaf pathogens that cause net blotch disease of barley. From different regions of Turkey during the years 2012-2016 and

Breeding barley for durable resistance to net and spot forms of net blotch

2021
This chapter focuses on breeding barley for durable resistance to net and spot forms of net blotch. It starts by reviewing how Pyrenophora teres f. teres can cause net form net blotch. The chapter then goes on to examine the molecular markers that can be identified to provide resistances to net form net blotch.

Effects of small air ions on net blotch disease of barley

International Journal of Biometeorology, 1977
Small positive air ions significantly reduced the number of lesions and percentage of leaf area covered by lesions of net blotch disease of barley. Appearance of disease symptoms was delayed by three days when plants were exposed to an atmosphere of positive ions. No such effect was observed for negative air ions.

Responses of Wild and Cultivated Barley from West Asia to Net Blotch and Spot Blotch

Crop Science, 1995
Wild species and cultivated landraces from the center of crop origin may provide new sources of resistance to a variety of plant diseases that plague genetically uniform crops around the world. This study was conducted to assess resistance to Canadian isolates of three foliar pathogens [Cochliobolus sativus (Ito & Kurib.) Drechsl.

Effects of net blotch on growth and yield of spring barley

Annals of Applied Biology, 1987
SUMMARYThe effect of net blotch on the growth and yield of cv. Beatrice spring barley was examined in a greenhouse experiment. Separate inoculations at growth stages 21 and 34 reduced green leaf area, root weight, leaf sheath and stem weight and tiller number.

Identification and mapping of net form of net blotch resistance in South African barley

Molecular Breeding, 2018
Net form of net blotch (NFNB) caused by the fungus Pyrenophora teres f. teres is an economically important foliar disease of barley (Hordeum vulgare) in southern and eastern Africa. Little attention has been given to disease resistance breeding, and knowledge about the presence of NFNB resistance in breeding lines is limited.
