Spore Liberation and Dispersal of Coffee Rust Hemileia vastatrix B. et Br.

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.
