Weedy rice (Oryza sativa L.), characterised by competitiveness, seed longevity, and
dormancy is a troublesome weed to rice fields. Furthermore, its close botanical affinity to
cultivated rice makes its control particularly difficult. However, winter flooding of rice fields
can be an efficient technique to control weedy rice infestation by promoting weed seed
decay, animal predation, or germination. The effects of winter flooding on weedy rice plant
and seed densities were assessed via two methods: field study of plant densities and …
