Water hyacinth is a floating plant with beautiful purple flowers. Water hyacinth control is difficult. The digester size has to be large compared with that of a traditional type due to the low gas production to plant volume ratio and this can in turn present problems for obtaining an airtight seal. Water hyacinth’s competitive ability was more than halved in the presence of the control agent (Bownes et al, 2010). Water hyacinth is possible to become feed fermented because of the high nutrient content. Water hyacinth is a very aggressive invader and can form thick mats.

Water hyacinth is a free-floating perennial water plant that forms large, dense mats on the water surface. These mortality agents produce distinct spatial patterns of damage within shoots. If these mats cover the entire surface of the pond, they can cause oxygen depletion and fish kills. Water hyacinth has a very high water content and therefore harvesting effort yields a low reward in terms of organic matter for conversion to biogas. In FWC management programs, the liquid formulations of 2,4-D are mixed with water and sprayed onto the leaves of water hyacinth and other broadleaf aquatic weeds including Cuban club-rush (Cyperus blepharoleptus) and primrose willow (Ludwigia spp.) damage of water hyacinth by N. eichhorniae’ larvae at four temperatures (15°, 20°, 25°and 30 °C).
