Salvinia molesta Mitchell possesses many characters of an aggressive aquatic weed. It is considered a noxious weed in freshwater ecosystems and agroecosystems in many warm areas of Africa, Australia and Southeast Asia. In spite of its weedy nature, Salvinia has some potential agronomic uses. Owing to its high nitrogen content (CP) of 20-33% per gram dry weight, Salvinia is used as livestock forage and is fed to swine, poultry and golden snail. In several instances, Salvinia is mixed with chicken manure and made into compost. The plant is grown in fishponds to encourage the growth of invertebrate larvae for prawn and fish food. Salvinia mulch is also applied to citrus plantations. There exist some agronomic potentials for the use of Salvinia biomass but any form of utilization that encourages its propagation will not be compatible with control. Salvinia molesta Mitchell has been declared an obnoxious weed by the Ministry of Agriculture, Plant Quarantine office.
