Abstract

Introduction of sugarcane rust into the Americas and its spread to Florida.

Abstract

Sugarcane rust appeared in the Americas in 1978, probably as a result of transoceanic transport of urediospores of Puccinia melanocephala from the Cameroons in West Africa to the Dominican Republic in the Caribbean. Based on upper-air wind trajectories, urediospores could have arrived in the Dominican Republic 9 d after they were airborne over the Cameroons. After rapid disease development in the Dominican Republic on the very susceptible sugarcane cv. B 4362, the rust spread in the Americas to Venezuela in the S. and to Florida in the N. by wind transport of urediospores.
