Pistia stratiotes is an aquatic plant, floating, perennial that can be propagated by seed or vegetatively by issuing numerous stolons at the end of which form girls plants. When the old leaves decay, fruits fall and sink to the bottom of the water where they eventually rot, releasing the seeds. As soon as there was light, the seeds germinate on the bottom of the water. When the first leaves develop, the spongy tissue allows the seedling back and float on the surface. This species has a very rapid growth. It doubles its biomass every 10 to 15 days depending on the temperature of the water and nutrients. Biomass production is in the order of 200 t / ha.

P. stratiotes prevents browsing, blocking dams, hampers access to water for livestock and people as well as fishing, blocking the pumps, intercepts the light, reduces the oxygen content increases from February to August After the evaporation of a free water surface, upsets the mineral balance, strong release of H2S. According to Rivers (2002), P. stratiotes can inflict a severe impact on the environment and economy of infested areas. The dense mats created by connected rosettes of the plant lead to the majority of problems encountered with water lettuce. These mats can have a negative economic effect by blocking waterways, thus increasing the difficulty of navigation and hindering flood control efforts. Mats of P. stratiotes can also disrupt natural ecosystems. They can lead to a lower concentration of oxygen in covered waters and sediments by blocking airwater interface and root respiration. Extremely thick mats of P. stratiotes can prevent sunlight from reaching underlying water. The cumulative effect of these negative characteristics of the plant is a loss of biodiversity in invaded habitats. P. stratiotes mats can also serve as a breeding place for mosquitoes.
Tanzania: Frequent and usually abundant.
Uganda: Frequent and usually abundant

Mechanical control: Mechanical control against P. stratiotes can be achieved in different ways - manual harvest to the net and at the fork from the shore, harvesting treadmill, harvest by harvester boat. This type of harvesting requires a piling on the bank followed by an evacuation by truck to another location or biomass will be left to rot. Given the speed of propagation of the water lettuce and the amount of biomass produced, this group of methods never allowed to fight effectively against an invasion by these species. These methods require a very large workforce and have a very high energy cost (carpets, boats, trucks) to be permanent. The only cases where these methods are maintained concerning the release of dams and water intakes of hydropower stations, catch water pumps water supply and the input channels and output port on large lakes and large rivers. Given the biomass produced and the growth rate provide for removal of 20 kg / m² every 10 to 15 days.
Chemical control: In France, only two molecules are approved for weed control of aquatic and semi-aquatic plants: efficient dichlobenil on monocots and dicots (80 to 160 kg.ha-1 pc depending on the water depth) Note that this product poses a risk of poisoning for high dose fish; glyphosate for the destruction of semi-aquatic plants helophytes (2160 g.ha-1 3240 until my g.ha-1 for my mallet). But the brutal and kills all water lettuce translates into a huge mass of organic matter flowing and breaks down at the same time, which results in a significant release of H2S in the middle.
Biological control: A weevil is proposed for the biological control against P. stratiotes. These are: Neohydronomus affinis Hustache (Coleoptera: Curculionidae, Erirhinae).
