| 520 | _aSymptoms of barley yellow dwarf (BYD) have been observed on cereals in nearly all countries of West Asia and North Africa. Its incidence, however, has varied during the last 15 years. Observations from field surveys are summarized. Since symptoms of barley yellow dwarf virus (BYDV) are of low diagnostic value, especially in wheat (Triticum aestivum L.), more precise qualitative and quantitative detection was derived by vector transmission and serology. In 1985 and 1986, preliminary surveys by enzyme-linked immunosorbent assay (ELISA) indicated that BYDV incidence in the regions surveyed in Syria, Morocco, and Tunisia was around 7, 22, | ||
