Abstract
Temporal progress of postbloom fruit drop of citrus in Florida was studied in four experimental plots of 25-81 3- to 4-yr-old trees of Valencia sweet orange in Gainesville and Lake Alfred and of Pineapple sweet orange and Ruby Red grapefruit in Hastings. Blossoms of central focal trees in each plot were inoculated with the slow-growing orange strain of Colletotrichum gloeosporioides. Incidence of trees and of open blossoms with postbloom fruit drop was monitored over time. Directionality of spread from a point source was measured in four contiguous quadrants of each plot. Disease gradients were estimated on four transects radiating from a central focal tree. Disease increased in intensity and spread in space following rain events in all four plots [...]
