Wheat streak mosaic virus (WSMV)<\/h1>\n

Disease symptoms<\/h2>\n

Wheat streak mosaic virus (WSMV) disease was first reported in the United States in 1922. Since its initial description in Nebraska, it has been found in throughout North America, Europe, and Australia. It is one of the most important and damaging wheat viruses in North America.<\/p>\n

WSMV disease develops as mosaic, chlorotic lesions or yellow streaks on wheat leaves, which lead to decreased growth and reduced yield (Figure 1). WSMV often co-infects plants with Triticum mosaic virus<\/em> (TriMV) and\/or High plains wheat mosaic virus<\/em> (HPWMoV), which together cause wheat mosaic virus disease, and are all transmitted by the wheat curl mite (Aceria tosichella<\/em>). WSMV, TriMV, and HPWMoV symptoms appear very similar, and it is not possible to reliably distinguish these viruses from symptoms alone. Laboratory tests must be implemented to determine and diagnose which viruses are present and causing the symptoms. The Colorado State University Plant Diagnostic Clinic<\/a> accepts plant samples for disease diagnostics, including viruses.<\/p>\n
