Abstract

Greenhouse evaluations of weeds and ornamentals commonly found in Florida citrus groves and greenhouses, respectively, indicated that Pratylenchus coffeae could be detected in roots of 15 of 27-plant species but most did not support high populations. The weeds Momordica charantia and Schinus terebinthifolius and the ornamentals Chamaedorea elegans and Codiaeum variegatum were found to be P coffeae hosts. P. coffeae was pathogenic to C. elegans and Brassaia actinophylla under greenhouse conditions. C. variegatum supported large P. coffeae populations on large, lesion-free root systems.
