4.6. Dicot weeds (Table 8)
The number of dicot weeds is considerably lower than those of
monocot weeds. Amaranthus species such as Amaranthus viridis L.
grow preferably in irrigated crops, for example, in maize and cotton.
This species is quite common for example in Africa (Rodenburg
et al., 2011). Trianthema portulacastrum L. is a frequent weed in
other crops than rice in India and Pakistan also (e.g., Reddy and
Tyagi, 2005; Saeed et al., 2010).
