LIQUID CULTURE FERMENTATION PRODUCTION OF MICROSCLEROTIA OF MYCOLEPTODISCUS TERRESTRIS AS A BIOHERBICIDE FOR CONTROL OF HYDRILLA VERTICILLATA. Submerged cultures of Mycoleptodiscus terrestris (MT) produce microsclerotial (MS) propagules when grown under specific nutritional conditions. A liquid culture fermentation method was developed to produce infective MS of MT for control of Hydrilla verticillata, an aquatic weed. When basal media w... Development of Mycolepodiscus terrestris as a biological control of Hydrilla In aquarium studies, Mycolepodiscus terrestris has previously been shown to be effective in controlling the invasive aquatic weed, Hydrilla. The development of M. terrestris into a commercially viable control option requires methods to produce, formulate, and disperse infective propagules. Our cur... Pilot-scale production and stabilization of microsclerotia of the potential mycoherbicide Mycoleptodiscus terrestris using deep-tank fermentation and air-drying. The fungus Mycoleptodiscus terrestris (Mt) is being developed as a bioherbicide for control of various invasive submersed aquatic plants including Hydrilla verticillata and Myriophyllum spicatum. A constraint to the commercial use of Mt as a bioherbicide is the development of an economic method for... SOMATIC MUTATION-MEDIATED EVOLUTION OF HERBICIDE RESISTANCE IN THE NONINDIGENOUS INVASIVE PLANT HYDRILLA (HYDRILLA VERTICILLATA) Hydrilla (Hydrilla verticillata L.f. Royle), a nonindigenous submersed invasive aquatic weed, has had a major economic and ecological impact on lakes and waterways in the southern and pacific coastal states of the U.S., displacing native beneficial species and dramatically altering the ecosystems. C... The origin of Hydrilla verticillata recently discovered at a South African dam Hydrilla was discovered during February 2006 at the Pongolapoort Dam on the Pongola River, KwaZulu-Natal, South Africa. Its presence there threatens a multimillion rand fishing and tourism industry. The South African Plant Protection Research Institute initiated control measures, a survey of the sur... PRODUCTION AND STABILIZATION OF MICROSCLEROTIA OF THE BIOHERBICIDE MYCOLEPTODISCUS TERRESTRIS PRODUCED USING DEEP-TANK FERMENTATION Hydrilla verticillata (L.f.) Royle (hydrilla) is considered one of the most important aquatic weeds in the world. Introduced into Florida in the 1950's, this invasive aquatic macrophyte is now found in lakes, ponds, reservoirs, rivers, and canals across the Southern United States. Mycoleptodiscus ... Drying and formulation of Mycoleptodiscus terrestris: A microbial bioherbicide of Hydrilla verticillata Mycoleptodiscus terrestris is a natural plant pathogen of the invasive aquatic weed, Hydrilla verticillata. Previous research has shown M. terrestris to be effective in aquarium and field assays in controlling the invasive weed. For M. terrestris to become a commercially feasible method of Hydrill... HYDRILLA, THE PERFECT AQUATIC WEED, BECOMES MORE NOXIOUS THAN EVER Hydrilla [Hydrilla verticillata (L.F.) Royale] was introduced in Florida lakes 50 years ago and is now one of the most serious aquatic weed problems in the United States. This plant possesses numerous mechanisms of vegetative reproduction that enables it to spread very rapidly. Management of this ... CHARACTERIZATION OF A HIGHER PLANT HERBICIDE-RESISTANT PHYTOENE DESATURASE AND ITS USE AS A SELECTABLE MARKER Three natural somatic mutations at codon 304 of the phytoene desaturase gene (pds) of Hydrilla verticillata (L. f. Royle) have been reported to provide resistance to the herbicide fluridone. We substituted the Arg304 present in the wild-type H. verticillata phytoene desaturase (PDS) with all 19 oth... Scale-up and formulation of Mycoleptodiscus terrestris: A biological control agent of Hydrilla Mycoleptodiscus terrestris is a natural plant pathogen of the invasive aquatic weed, Hydrilla verticillata. In aquarium and field assays, it has been shown to be effective in controlling the pervasive weed. The development of M. terrestris into a commercially viable bioherbicide requires developin...       Last Modified: 02/09/2010 ARS Home | USDA.gov | Site Map | Policies and Links  FOIA | Accessibility Statement | Privacy Policy | Nondiscrimination Statement | Information Quality | USA.gov | White House
