Fight against water hyacinth Eichhornia crassipes (Mart.) Solms, 1833

Résumé

Water hyacinth originating from South America was introduced into several regions of the world as an ornamental plant. Its biological characteristics, including capacities of sexual and asexual reproduction ways very effective, its high growth rate and productivity, allowed it to colonize freshwater communities and be very competitive to other plant species. E crassipes shows the most significant growth rate in comparison with other terrestrial or aquatical species. Because of its ecological and socio-economic impacts, it belongs to the "100 most harmful invasive species in the world”.  Several methods of fight such as physical, chemical and biological are adopted to eradicate this invasive plant. Given the limitations of use of these different methods, the development of an effective short-term control technique without major environmental impact would be an adequate solution to combat its expansion.
