SUMMARY Verticillium wilt of Pelargonium x domesticum caused by Verticillium albo‐atrum and Verticillium dahliae is recorded in the U.K. Naturally‐infected plants showed severe symptoms during the summer but there was some recovery in the autumn and winter. In experiments, symptom severity increased at high temperatures but was not markedly in fluenced by day‐length treatments. Isolates of V. dahliae from chrysanthemum and pelargonium readily infected either host. Benomyl drenches at 1·5 g/4·5 1. at the rate of 200 ml/plant suppressed symptom expression and resulted in a high proportion of healthy cuttings from infected stock plants.
