Korea lists this pathogen as Leptosphaeria spp. This pathogen has been reported in Korea.
3 Known Hosts
Triticum aestivum
wheat
Yes
LEPTNO-3,LEPTNO-4,LEPTNO-8,LEPTNO-9
Seed as a pathway is well established and accepted. Seed transmission has been established (Shah, et.al., 1995) though the importance of seed borne inoculum in disease development is unclear (CABI, 2020)
Yes
Blotter incubation, Culture plating, Serology
LEPTNO-1,LEPTNO-5,LEPTNO-7
Fungicide seed treatments
Seed treatments (carboxin + thiram, guazatine triacetate, maneb, oxine-copper and thiram) have been used.

Fungicide seed treatments
Seed treatments (carboxin + thiram, guazatine triacetate, maneb, oxine-copper and thiram) have been used for wheat seed and may be effective on barley seed.

Secale cereale
rye
No
RICH ISTA
No references found indicating seed is a pathway in rye. Seed pathway is inferred because the pathogen may be seed borne in wheat and barley. Rye is a known host.
