Synopsis Yield reduction caused by the barley yellow‐dwarf virus in three spring oat varieties and the possible role of time of infection was considered by inoculating plants at the 3‐leaf and boot stages of growth. Average infection in the non‐inoculated controls and in plants inoculated in the seedling and boot stages was 1.1, 93.8 and 15.6%, respectively. Yield reductions for the three varieties inoculated in the 3‐leaf and boot stages, respectively, were: Fayette, 92.5 and 10.1%; Clintland, 94.4 and 21.8%; and Rodney, 75.8 and 15.0%.
