Pythium Control for Container-Grown Longleaf Pine Seedlings

Damping-off is a major problem in growing conifer seedlings in containers (3). Close spacing and high fertilization in humid greenhouses promote disease spread and intensification. At the Stuart Project in central Louisiana losses have been heavy, especially on longleaf pine. Fusarium, Rhizoctonia, and Pythium species are the organisms that have been responsible (2). Many fungicides effective against one organism fail to control others; therefore, controls often must be developed for each pathogen. In this study, 10 fungicides were tested and compared for controlling Pythium on longleaf pine. Seven of these fungicides are registered for Pythium control on various horticultural or ornamental crops and three are experimental fungicides known to inhibit Pythium.
