SUMMARY An improved in vitro test is described for determining the pathogenicity of Fusarium solani f.sp. pisi isolates on pea. This technique involves the use of polypropylene fibre Milcap plugs to suspend peas in boiling tubes containing spore suspensions in 0.1% water agar. Results were available after 14 days of incubation at 25°C. Four levels of pathogenicity were detected on pea cultivars Little Marvel and Dark Skinned Perfection using a total of eight isolates and strains of F. solani f.sp. pisi.
