4.5.2. Broadleaved monocots (Table 7)
Most monocot broadleaved weeds are typical aquatic species,
for example, Alisma-, Heteranthera-, Monochoria-, and Sagittariaspecies.
This is why they are usually found in flooded and paddy
rice systems. Alisma- and Heteranthera-species are frequent weeds
in direct-seeded, flooded rice in Europe. Monochoria- and
Sagittaria-species do not play a role as weeds in Europe. They seem
to prevail in areas of transplanted rice or in California and Australia
where pre-germinated seed is sown by aeroplane.
