To investigate occurrence and control technology of windflower leaf spot, the incidence of leaf spot on windflower in Liaoning was investigated by five point sampling and the method of combining large census. It was found that occurrence of windflower leaf spot caused by Ascochyta anemones Kab. et Bub. was closely to cultivated variety, plant age and cultivation pattern. The diameter of the spot was coincided with the field disease trends. This disease could be effectively controlled by procymidone 50%WP, pyrimethanil 40%SC, azoxystrobin 25% SC at its early stage.
