Abstract
Nutman, Roberts and Bock1 have produced evidence recently that Hemileia vastatrix uredospores are not liberated into the air from fructifications by wind alone at speeds up to 12.5 miles/hr. and only in small quantities if the supporting leaf flutters violently. They infer that contact of water with the pustules is the principal method of liberation.
