Biological Control of Water Weeds with Plant Pathogens.

摘要

Both endemic and exotic plant pathogens were evaluated as biological control agents for water weeds. Additional studies investigated the potential use of an integrated program of biological control using plant pathogens and insects. Of the endemic pathogens tested,Rhizoctonia solani, Acremonium zonatum and Cercospora rodmanii exhibited potential as biocontrols. The latter fungus was the most promising. In fact, C. rodmanii was established as the causal agent of a decline disease which effectively controlled waterhyacinths in Rodman Reservoir in two out of the last five years.
