Observations on the Development of Leaf Blotch and Net Blotch of Barley from Barley Debris, 1968

Plant Pathology, 1969
SUMMARY A survey of 56 fields of spring barley in West Sussex in 1968 showed that the extent and severity of leaf blotch ( Rhynchosporium secalis ) and net blotch ( Pyrenophora teres ) in the crop depended on the amount of stubble ...

Monitoring fungicide resistance frequencies – a case study of barley net blotch

bioRxiv
BACKGROUND Decreased sensitivity to fungicides impacts the effectiveness of fungicide applications for managing plant disease, in some cases resulting in field-level failures.

Sensitivity of Resistance to Net Blotch in Barley

Journal of Phytopathology, 1999
The aim of this study was to demonstrate various methods of analysing terminal net blotch, Pyrenophora teres Drechs. f. teres Smedeg., severity data from 15 spring barleys, Hordeum vulgare L., grown in Finnish official variety trials in five environments.

Interaction of net blotch and scald on barley

Canadian Journal of Plant Pathology, 2008
Abstract Net blotch caused by Pyrenophora teres f. sp. teres and scald caused by Rhynchosporium secalis are major foliar diseases of barley (Hordeum vulgare) and often occur together in the same fields in central Alberta, Canada. The differential development of these two diseases in relation to seeding date was investigated in five field trials in 2001

Advances in understanding the epidemiology, molecular biology and control of net blotch and the net blotch barley interaction

2021
Net blotches are the most widely distributed foliar diseases of barley worldwide, causing significant losses in grain yield. They occur as net form net blotch, caused by Pyrenophora teres f. teres and spot form net blotch caused by P. teres f. maculata. Both sexual and asexual reproduction play a role in the P.

Quantitative genetics of net blotch resistance in barley

New Zealand Journal of Agricultural Research, 1985
Abstract A half diallel was made amongst 5 barley (Hordeum vulgare L.) genotypes (Zephyr, Hassan, Mata, Kaniere, and Manchuria) which varied in resistance to net blotch disease, caused by the fungus Drechslera teres (Sacc.) Shoem. The 5 parents and 10 F1 progeny were grown to physiological maturity in a controlled environment.
