barley
Causes net blotch of barley. Primary infection occurs from seed-borne inoculum and produces lesions on the first leaves, which are at first pale but develop into dark spots or streaks later. Secondary infection on older leaves produces pale brown blotches, in which is a network of dark brown lines; these may later coalesce to form irregular leaf stripes. Lesions also occur on the floral bracts. On other hosts the reticulate pattern of the lesions is usually absent
