摘　　要：采用正交试验设计方法,将50%退菌特、80%杜邦万生、72%杜邦克露3种药剂用于20 a生红松人工林内蜜环菌根朽病防治试验.发病状况分为5个等级,对防治效果进行方差分析和统计假设差异性检验.结果 表明：3种药剂之间无显著性差异,而与对照组比较差异显著.防治的经济效益十分显著.投入产出比达到1：167.Tuzet, Manzate and Curzate were tested on Armillaria root rot in 20 year-old Pinus koraiensis. Adopting the orthogonal design. Disease symptom was graded to 5 scales. Control effects were analyzed with the variance and the statistics otherness-test. Results showed that control effects are some for medicaments, and different for the antitheses. Economy benefit was quite visible, the percentage to jump in to out put was 1：167.
