Description

In Chiba prefecture, a new leaf spot of velvet grass, meadow fescue and rye was observed. From inoculation tests and some morphological studies, they were identified as Helminthosporium sorokinianum Sacc. ex Sorokin (=H. sativum P.K. et B.). This seems the first odservation of the fungus infecting velvet grass (Holcus lanatus L.) in the field. In inoculation tests, tall fescue was observed to have some resistance to the fungus from meadow fescue.
