Abstract: Four commonly used seed dressing agents, Cuirui+Aierjia, Banyouyi+Weifu, Gaoqiao and Liangmiao were selected for plot experiment. Through the investigation of peanut seedling emergence rate, seedling preservation rate, yield and economic characteristics, the application effect of seed dressing agent was analyzed and evaluated, and the agents with good control effect and high safety were screened. The results showed that the four medicines had obvious effects on preventing peanut seedling diseases, increasing emergence rate and reducing the dead seedling rate. Compared with the control （no seed mixing）, the economic traits were improved and the yield was increased significantly. Among them, the effect of Liangmiao was the most prominent, the emergence rate and seedling preservation rate were the highest, reaching 95.8% and 91.5%, respectively, and the yield increase range was the highest, reaching 33.6%. The number of effective branches per plant and productivity per plant were higher, and the economic traits such as full fruit weight, 100-fruit weight, 100-kernel weight and pod plumpness were better.

Key words: peanut, seed dressing agent, peanut disease
