| Molecular characterization of twenty-eight strains of Fusarium oxysporum using vegetative compatibility grouping and SCAR primers allowed the taxonomic confirmation of the strigae forma specialis of this fungal species. Field studies examined the virulence of three strains (M12-4A, PSM 197 and Foxy 2) inoculated in various formulations. The experiment pursued the goal of integrating several weed control measures in both maize and sorghum crops. Elements of plant breeding and Striga germination inhibitors were tested alongside of the use of a mycoherbicide. The field research was repeated in a dry climate (Eastern Burkina Faso) and in a region of abundant rainfalls (Eastern Benin) to examine effects of environmental conditions on fungus efficacy. Application of F. oxysporum was especially beneficial in maize, and when combined with a resistant cultivar, lead up to 99.7% of reduction in Striga emergence. Results will further encourage the development of several strains as viable and environmentally safe biocontrol agents to be used against Striga hermonthica. |
