Evaluation of the Growth, Sporulation, Fungicide Efficacy, and Host Range of .

was primarily identified based on the characteristics of its conidia and several sequences. The fungus causes severe leaf spot disease on hairy vetch ( var. ) in Yunnan Province in China. The growth, sporulation, fungicide efficacy, and host range of the pathogen were evaluated to aid in disease management. Different types of culture media and carbon and nitrogen sources were used to evaluate the growth of Oatmeal, maltose, and potassium nitrate agar had a higher amount of sporulation. Difenoconazole (10%) was the most effective fungicide against the leaf disease caused by . In addition, foliar inoculation sprays were used to assess the host range of in six different plant species, including alfalfa ( L.), sainfoin ( Scop.), erect milkvetch ( Pall.), common vetch ( L.), red clover ( L.), and white clover ( L.). successfully infected these plants, indicating that it has a wider host range than hairy vetches.
