A mosaic of wheat was first observed in Nebraska by Peltier in 1922. According to Haskell and Wood (1923) Peltier found diseased plants in a large number of winter and spring wheat varieties at Lincoln and, in some instances, he successfully inoculated wheat and corn from the juice of infected plants. The temperatures under which Peltier maintained his inoculated plants are unknown and other criteria now employed to characterize the viruses were not utilized. It is probable, however, that he was working with what is now known as wheat streak mosaic virus.
This bulletin reports the results of studies on the epidemiology of wheat streak mosaic under Nebraska conditions. Particular attention is given to the occurrence and certain characteristics of the mite vector of the virus, the relation of weather and other factors to some of its activities, a correlation of certain mite situations with epidemics of the disease, and recommendations for disease control.
