Weeds interfere with turfgrass growth lowering functional and aesthetic quality of lawns. Conventional weed control using synthetic pesticides is hazardous to lawn users and to the environment while cultivation alone is not sufficient. A study was conducted with the aim of exploring the potential of biofumigation with African spider plant (Cleome gynandra) as an environmentally friendly alternative to use of synthetic herbicides for establishment of weed-free Paspalum notatum turfgrass. Chopped Cleome gynandra incorporated into the soil at 4, 6 or 8 kg m -2 was compared with Basamid® (97% Dazomet) at 0.029 kg m -2 (positive control) and untreated (negative control) in a randomized complete block design experiment with four replications. Population of various weed species in the experimental plots was recorded weekly. Total fresh and dry weight of the weeds was also determined after weeding the plots. Paspalum plug width and height were measured every 14 days and sprig internode length, leaf length, leaf width, fresh and dry weights were measured on monthly basis to determine treatment effect on the growth of the turfgrass. Treatment effect on aesthetic quality was visually determined monthly using a rating scale of 1 to 9 to evaluate uniformity, colour, density and overall quality. Rating was based on the differences observed, nine being the outstanding treatment and one the poorest. The data collected were subjected to analysis of variance. Biofumigation with Cleome gynandra at rates of 6 or 8 kg m-2 was as effective as Basamid ® at 0.029 kg m -2 in significantlysuppressing Galinsoga parviflora, G. ciliata and Bidens pilosa weed populations.
