Because they are a source of resistance to or tolerance of biotic and abiotic stresses, the most important use of the various species of wild rice is probably in breeding programmes to improve the species of cultivated rice (Oryza sativa, Oryza glaberrima). However, this species is also valuable for use as a food supplement in India and Sri Lanka, and as famine food when other crops fail. In many parts of South Asia, wild rice grains are used as an offering to Deities in the temples and can command a high price in the market where they are sold during religious festivals[

This species is widely believed to be the closest related species to the cultivated rice (Oryza sativa). It is spread widely through the tropics and subtropics and is considered to be invasive in many parts of Central and South America where it has become naturalized. It is considered to be a weed in rice fields, as it easily crosses with the cultivated rice, reducing its market value[
