Abstract: Four sampling points from Jiayuguan, Gansu province were investigated to determine the pathogen, pathogenicity, and dominant population of onion basal plate rot disease. Based on morphological and cultural characters the disease pathogens were identificated as Fusarium oxysporum, F. solani and F. moniliforme. The dominant species was F. oxysporum and although pathogenicity testing showed that the three species could cause onion basal plate rot disease, F. oxysporum had the strongest pathogenicity and its disease rate and disease index reached 84.4% and 65.3, respectively. Compared with the other fungi, there was a significant difference. Laboratory toxicity tests of four fungicides to the mycelial growth of the three species showed that 200 μg/L of the Shijunke fungicide had the strongest activity. 
