Efficacy assessment of antifungal metabolites from Chaetomium globosum No.05, a new biocontrol agent, against Setosphaeria turcica

► One of the very few reports on biological control of northern corn leaf blight (NCLB). ► Strain No.05 strongly reduce disease on detached maize leaves and on seedlings. ► Two antifungal substances are obtained from strain No.05 by bioassay-guided isolation. ► Chaetoglobosin A displays potent suppression of Setosphaeria turcica both in vitro and in planta.
