The relationship betweenVerticillium wilt and the pinkeye disease on potatoes

Abstract

In both greenhouse and field experiments, a relationship was evident between the organismVerticillium albo- atrum and the pinkeye disease of potatoes. The fungicide, benomyl, was used to controlVerticillium after 2 and 4 weeks of contact with young potato seedlings. The mature tubers formed on these seedlings had varying amounts of pinkeye, depending on the potato line or variety tested. Seedlings that were first seed treated with benomyl and then inoculated withVerticillium did not develop pinkeye.Rhizoctonia also induced or stimulated pinkeye development.
