Interpretive Summary: This article is a general description of the disease known as barley stripe mosaic and the virus which causes it. It has been prepared for an electronic (CD-ROM) publication which provides descriptions, illustrations, maps, and other information useful for plant disease control. In particular, this publication is intended to improve the availability of useful scientific information to developing countries. Thus, this article discusses the similarities of barley stripe mosaic to a fungal disease known as barley stripe. Seedborne aspects of disease are discussed in relation to virus incidence and effects on seed quality. Virus transmission, diagnosis, and control are also discussed.

Technical Abstract: Barley stripe mosaic is a disease induced by a viral pathogen known as barley stripe mosaic virus (BSMV). Symptoms can be confused with symptoms of barley stripe, a fungal disease caused by Pyrenophora graminea. A description of symptoms of both diseases is provided to facilitate distinction of the two. Seedborne aspects of disease are discussed in relation to virus incidence and effects of infection on seed quality. Seed transmission of BSMV in barley has been studied extensively. BSMV infection can result in sterility, fewer and smaller seeds, shriveled seeds, and reduced germination. Transmission of BSMV through seed to progeny is well known and is influenced by both host and virus genotype and environmental factors. Although it has no known insect vector, the virus can spread through a field by plant to plant contact. Dependence on seed transmission for the survival of BSMV has resulted in the development of regulatory control measures in some areas. A number of effective serological assays have been developed for diagnosis and are used in association with seed certification programs. Host resistance has also been identified and can be incorporated into commercial cultivars.
