Barnyard Grass

About this weed

Echinochloa crus-galli, is a wild grass also known as Barnyard grass or Watergrass
It is a tall, tufted annual with a coarse stalk. The thick culms (hollow and jointed stems) branch from the base and are 0.8-1.5 m tall. Stems often grow along the ground before turning upward.
Barnyard grass flowers throughout the year and can produce seeds within 60 days. It prefers moist to wet land and easily grows in direct-seeded rice fields and wastelands. It is a common weed in swamps and aquatic places.
It stops growing and most of the plants die when the water depth reaches 15 cm. Flooding rice fields with as little as 2-3 cm water after planting will give good control of this grass weed.
