dc.descriptionAbstract: The fungus Cercospora rodmanii Conway has been shown to have good potential as a biological control agent for waterhyacinth in Florida. Previous work has shown what will happen if known quantities of the fungus are placed on an area of waterhyacinth. This current research addresses the study as optimal levels of inoculum necessary to begin an epidemic, various levels of inoculum on small populations of waterhyacinth, morphological changes of the infested plants, the effect of subsequent inoculations on infested plants, and the effect of off-the-shelf fungicides on Cercospora rodmanii. It was shown that the fungus can severely affect waterhyacinth in conditions that favor a reduced growth of the plant. The Cercospora rodmanii can be controlled with available fungicides if necessary. The greatest effect of the fungus on waterhyacinth was in reduction in height of the plants. Secondary infestations can occur with the spread of the disease from inoculated plants.-
