Abstract
Fifteen Fusarium oxysporum isolates from diseased parasitic weeds (Striga hermonthica plants) were evaluated over two years (1997-98) to identify the most effective isolates for the control of the parasite in infested sorghum fields in Burkina Faso. In both years the fungus was found to reduce 7 Striga infection in sorghum by 50% although no significant differences were found among the 15 isolates in this respect. In 1997, Striga emergence was delayed by 10 days and the 47% reduction in Striga biomass is attributed to the effects of fungal isolates, whereas in 1998, Fusarium reduced emerged Striga densities by 45%. However, there is need for improved bioherbicide formulations and delivery systems to enhan ce the potential role of biological control for integrated management of the parasite in Burkina Faso.
