|a Rice false smut, caused by the pathogen Ustilaginoidea virens, is a severe emerging disease in China. It affects not only the quality of rice but also yields of rice production. To make clear the effect of chemical seed treatment on the rice false smut control in fields, during 2014 to 2017, four fungicides with different modes of action were used to treat rice seeds contaminated by false smut balls. In rice-growing seasons, samples of rice tissues were taken for detection of U. virens by using a specific nested PCR method at different rice-growing stages. In addition, the occurrence of rice false smut was investigated at maturation stage. Results showed that U. virens in plant tissues decreased significantly at the seedling stage upon chemical seed treatment. Four chemical treatments decreased the detection rate significantly (P < 0.01) compared with the water treatment, but no significant difference was observed among four chemical treatments. However, the detection rate did not decease significantly at the tillering and booting stages. Similarly, the final occurrence of rice false smut did not show significant difference between each chemical and water treatment. These results suggested that chemical seed treatment had only limited efficacy in preventing occurrence of rice false smut; application of fungicides at the booting stage or integrated use of fungicides and agricultural practices might give a better control for this disease
