From phytosociological sampling carried out between 1999 and
2005 in cotton culture in the North of Ivory Coast, more
than 230 weeds species were inventoried. Among those,
Euphorbia heterophylla, Ageratum conizoides, Bidens pilosa
Tridax procumbens, Boerhavia diffusa and Chromolaena
odorata were the most abundant species causing weeding
problems to farmers. A test that used herbaceous Fabaceae:
Crotalaria sericea, Mucuna pruriens, Pueraria
phaseoloides and Vigna unguiculata to control
these weeds was carried out in some localities at Bouaké in
the center of the country, Korhogo in North and Odienné in
the North-West. The results showed that annual Leguminous
species like C. sericea, M. pruriens and V.
unguiculata, used in previous culture, decreased the
rate of weeds on the different plots. P. phaseoloides,
Leguminous perennial species was indicated in improved
