To select better fungicide for the control of sugar beet cercospora spot, the experiment which was done in one of the main production area in Heilongjiang Province, Hailun City was taken the method of field pots and was used Nustar, Iprodione, Difenoconazole, Mancozeb, Thiophanate-methyl, Azoxystrobin, Pyraclost robine to foliar spray for SD13829 at three stages. Through the survey of prevalence situation and the comparison between production and sugar content, the result showed the last control effects can achieve 27.61%-68.26%, the seven fungicides increased the yield 4.85%-15.28%, increased the sugar yield rate 5.74%-24.20%and sugar content 0.63%-7.73%after spraying fungicides three times. Nustar and Difenoconazole had the better control effects for bactericide. The effects were 60.73%and 68.26%, the yield increased 15.28%and 13.14%, the sugar yield rate increased 7.73%and 5.99%, sugar production increased 24.20%and 19.91%.They could be used in the production.
