Molecular characterization of carbendazim resistance of Fusarium species complex that causes sugarcane pokkah boeng disease
Abstract Background Pokkah boeng is one of the most serious and devastating diseases of sugarcane and causes significant loss in cane yield and sugar content. Although carbendazim is widely used to prevent fungal diseases, the molecular basis of Fusarium species complex (FSC) resistance to carbendaz...
