[0038] The present invention provides a preparation method of carboxamidophenazine biological fungicide, including the following steps:
[0039] S1. Inoculate the activated Pseudomonas chlorophylla into liquid medium A, shake flask culture, and obtain seed liquid A. Among them, the liquid medium A includes the following components by weight: 1-5 parts of glucose, 1-5 parts of tryptone, 0.5-1.5 parts of ethanol, 0.5-1 parts of acetone, 0.05-0.15 parts of potassium dihydrogen phosphate and chlorinated 0.05-0.1 parts of sodium, 100-120 parts of water, pH 6.5-7.3. The conditions of shaking flask culture are: shaking culture in a shaker at 25-30°C for 15-20 hours, and the rotating speed of the shaker is 200-250r / min.
[0040] S2. Inoculate the activated Pseudomonas aeruginosa into liquid medium B, shake flask culture, and obtain seed liquid B. Wherein, the liquid medium B includes the following components by weight: 0.5-3 parts of sucrose, 0.5-2 parts of glucose, 2-5 parts of tryptone...
