SUMMARY Experiments using thiabendazole (2‐(4‐thiazolyl) benzimidazole) for thé control of Verticillium albo‐atrum in lucerne are described. In in vitro tests thiabendazole completely inhibited fungal growth. In the glasshouse, spray treatments were ineffective but a soil drench treatment using 50 p.p.m. of active ingredient proved the most effective. In some other treatments phytotoxicity was observed. In most cultivars in a field trial there appeared to be a cumulative reduction in wilt development with further applications of fungicide: in cvs. Du Puits, Europe, Flamande and Provence the reduction occurred more quickly than in Cardinal, Emeraude, Eynsford and FD100.
