Abstract
DURING the past year, the survey of a number of small Citrus groves has led me to conclude that a disease similar to “tristeza” is present in Venezuela, chiefly in the States of Carabobo and Aragua up to Sucre; western areas were not investigated. The disease has been previously attributed, by local agronomists, to high or deficient soil moisture or to an unclassified root injury, for the decay of rootlets, then of larger roots, occurs simultaneously with decline of the tops.
