Abstract

Invasive alien weeds pose a serious threat to the biodiversity and are a significant constraint to agricultural production worldwide. Water cabbage (Limnocharis flava (L.) Buchenau), is one such aquatic weed, which was introduced in Asia as an ornamental species because of its attractive foliage and colorful flowers. It has subsequently naturalized and became a major weed in rice field, irrigation canals and wetlands in South-East Asia and has now attained the status as an alien invader. Developing an effective integrated management program requires a thorough understanding of the biology and ecology of the weed to identify the most vulnerable stages of its life cycle. Location-specific studies on the behavior of weeds, their population dynamics, seed bank and other features provide information on the positive or negative influence of biotic and abiotic factors on their growth and development which elaborates better control operations. Therefore literature regarding eco-biology, modes of propagation, dispersal and different methods for the sustainable management of water cabbage is reviewed in this paper.
