Experiments were conducted at the Dingle Agricultural and Technical College farm and in a farmer's field in Dingle, Iloilo [Philippines] to determine the effect of Salvinia molesta D.S. Mitchell on rice (Oryza sativa L.). Grain yields of wet-seeded and transplanted rice were not affected by the time of flooding and duration of weed competition. However, seedling mortality in both crops occurred with early flooding when S. molesta was present. Also, weed competition in wet-seeded rice during the first 14 days after seeding (DAS) resulted in significant stand reduction
