摘要：
A survey was made of weeds in fields of sorghum, millet and maize at 37 localities in Burkina Faso. The survey covered 403 fields, 152 in 1988 and 251 in 1989. A total of 272 adventive species were recorded, 60% of them in both years. Fifty-six species were found which were new to the Burkina Faso flora. An analysis of the floristic and biological spectra, together with the geographical distribution, revealed certain characteristic features of the weed flora. The information obtained with regard to the frequency and abundance of the species makes it possible to define the principal weeds of annual crops in Burkina Faso.
