Field and Laboratory Studies of the Fungus Mycoleptodiscus Terrestris as a Potential Agent for Management of the Submersed Aquatic Macrophyte Hydrilla Verticillata.
Abstract
Laboratory and field studies were undeflaken to assess the potential of a fungal pathogen as a biocontrol agent for the management of Hydrilla verticillata (L. fil.) Royle. The pathogen previously reported to be Macrophornina phaseolina (Tassi) Goid was positively identified as a strain of Mycoleptodiscus terrestris (Gerd.) Ostazeski. Laboratory tests reconfirmed that M. terrestris produced characteristic disease symptoms on hydrilla tissues followed by a significant reduction in aboveground biomass. Assessment of M. terrestris in a field situation was conducted on hydrilla-planted ponds at the Lewisville Aquatic Ecosystem Research Facility. Aboveground biomass of the host plant was significantly reduced 4 weeks postinoculation with a mycelial matrix of the fungus.
