Weeds are a serious problem in this region during both the establishment of pastures and their productive period, causing serious reduction in growth, vigour, productivity and persistence. Factors responsible for weed infestation and possible methods of prevention and control are outlined in this paper. The biology and weed Ecology of Cassia alata, Digitaria insularis, Jatropha gossypifolia, Mimosa spp, Sida spp, Solanurn rnauritianurn and Solanum torvum are briefly described and detailed recommendations are given for the control of these weeds.
