The invention discloses a dictyophora rubrovalvata yellow liquid exudation disease treatment method. The method comprises removing dictyophora rubrovalvata with the yellow liquid exudation disease, orderly spraying a cyhalothrin 1400- to 1500-fold solution, a strong Bingduqing 900- to 1000-fold solution, a Youmeijing 1000- to 1500-fold solution and a triacontanol 1000- to 1300-fold solution with a mass percentage concentration of 0.1% to the dictyophora rubrovalvata, orderly spraying a dimethyl phosphate 900- to 1000-fold solution, a chlorine dioxide 1000- to 5000-fold solution and a calcium tablet 1800- to 2000-fold solution to the dictyophora rubrovalvata, orderly spraying a Guchongyixunjing 800- to 1000-fold solution, a yellow spot removal agent Huangbanjuesha 1000- to 1500-fold solution, a Youmeijing 1000- to 1500-fold solution and a potassium dihydrogen phosphate 1900- to 2000-fold solution to the dictyophora rubrovalvata and spraying clear lime water with a mass percentage concentration of 3-7% to the dictyophora rubrovalvata, wherein the spraying process is carried out at time intervals of 24-36h. The dictyophora rubrovalvata yellow liquid exudation disease treatment method has the characteristics of good treatment effects, strong specificity and simple operation.
