Embodiment 1
[0020] Example 1 In order to determine the bacteriostatic effect of different proportions of fluazinam and Jinggangmycin on rice sheath blight bacteria, the indoor toxicity determination of different proportions of fluazinam and Jinggangmycin on rice sheath blight bacteria was carried out. According to the weight percentage in the table, the corresponding concentration is made, and the test results are reported as follows:
[0021] Table 1 Toxicity test results of fluazinam and Jinggangmycin single agent and their mixture against rice sheath blight
[0022]
[0023] The test results showed that the mixture of fluazinam and Jinggangmycin at a ratio of 1:5 to 1:10 could strongly inhibit the growth of rice sheath blight mycelium, and the synergistic effect was the most obvious in the ratio of 1:10 .
Embodiment 2
[0024] Embodiment 2: Weighing percentage by weight of 11% Jinggangmycin Fluazinam wettable powder:
[0025] Jinggangmycin 10%
[0026] Fluazinam 1%
[0027] NNO (dispersant) 3%
[0028] Sodium lignosulfonate (dispersant) 7%
[0029] Sodium alkylbenzene sulfonate (dispersant) 1%
[0030] Silica (filler) 78%
[0031] Weigh the materials according to the above weight ratio, add each material successively under stirring, after being pulverized by a jet mill and then stir and mix uniformly, the product is obtained, and the field drug efficacy test for preventing and treating rice sheath blight is carried out. The disease control effect is 80%.

[0034]
Embodiment 3
[0035] Embodiment 3: The weighing percentage by weight of 22% Jinggangmycin fluazinam suspension concentrate:
[0036] Jinggangmycin 20%
[0037] Fluazinam 2%
[0038] Nonylphenol ethoxylate (NP-9) (dispersion wetting agent) 8%
[0039] Propylene glycol (antifreeze) 1%
[0040] Xanthan gum (thickener) 1%
[0041] Silicone defoamer (SAG612) 2%
[0042] Water (filler) 77%
