Abstract
Three grapevine diseases of economic importance that have been identified in New York State are described here. One disease is induced by tomato and tobacco ringspot viruses and causes a decline of grapevines. A second disease is characterized by trunk cankers that enlarge gradually and kill the grapevines. Eutypa armeniacae Hansf. & Carter is always isolated on artificial media from established cankers and is likely the causal agent involved. The third disease with downward curling and yellowing of leaves, delayed ripening of shoots, and shriveling of berries is of limited occurrence and the causal organism is unknown.
