Weed potentialFimbristylis littoralis is a serious weed in rice. It competes strongly with crops for light and nutrients, can adversely affect rice germination and interferes with crop management. In India, rice yield losses due to F. littoralis (together with Cyperus difformis and Scirpus supinus) were estimated at 9% in transplanted rice in the dry season and 24-32% in direct-sown rice in puddled conditions The weed can also outcompete native vegetation. Fimbristylis littoralis is a secondary host of pests and diseases such as rice earhead bug (Leptocorisa acuta), paddy armyworm (Mythimna separate) and rice sheath blight (Rhizoctonia solani). |
