The effects of tomato ringspot virus (TomRSV) on plant and fruit development of raspberries vary considerably, depending upon the variety. Infected Fairview plants were severely injured in the first two years of the plantation. Plant vigor and fruit yields were markedly reduced. In the third year there was a rapid decline of the plants, characterized by 10 to 80% of the fruiting canes being partly or completely killed, and leaves on the new cane growth of infected plants showing epinasty and early abscission. It is suggested that what was often considered to be winter injury may have been caused by infection with TomRSV. Infection in Newburgh, Sumner and Willamette raspberries had little or no effect on plant and fruit development.
