  • To investigate the pathogen species of silage maize leaf spot in Minhe County, the diseased leaves with typical symptoms were collected from the corn planting area. The diseased leaves were classified according to the symptoms. The strains of pathogen were obtained by tissue isolation method, and the isolates were identified by molecular biology method. The results showed that there were three types of leaf spots observed in Minhe County. The first type of spot was irregular, large lesions, in brownish yellow color. The second type of spot was long strip, yellow brown in the center, or purple brown or dark brown in the edge, sometimes with 2~3 concentric rings, and the vein could be infected. The third kind of lesions were oval, slightly larger, yellow, scattered on the leaves. Fourteen isolates were isolated and identified by rDNA-ITS sequence analysis as Alternaria alternat, A. burnsii, A. tenuissima, Fusarium proliferatum, F. tricinctum and F. longifundum. The pathogens caused corn leaf spot in Minhe County belonged to 2 genera, 6 species, respectively. The main pathogens are Alternaria.
