Embodiment 1

[0026] Formulation example 1: 48.8% fenoxazone · florasulam (48:0.8) wettable powder

[0027] Sequentially add 480 grams of fenpyramid, 8 grams of diflusulam, 230 grams of white carbon black, 160 grams of naphthalenesulfonate formaldehyde condensate, 42 grams of sodium lauryl sulfate, 600#-P polycarboxylic acid Put 80 grams of salt into the mixer, stir for 30 minutes to mix the materials evenly, and pulverize them to about 900 mesh with a small airflow mill to obtain 48.8% fenoxafen · diflusulam (48:0.8) wettable powder .

Embodiment 2

[0028] Formulation example 2: 25.5% fenoxazone · florasulam (25:0.5) wettable powder

[0029] Put 250 grams of fenpyramid, 5 grams of florasulam, 50 grams of NNO, 65 grams of sodium lignosulfonate, 130 grams of white carbon black, and 500 grams of kaolin into the mixer, and stir for 30 minutes to mix the materials Evenly, and then pass through the jet mill, and the fineness of the material passes through a 325-mesh sieve. Then, the materials were mixed and stirred again in the mixer to obtain 25.5% wettable powder of oxentrafen·flusulam (25:0.5).

Embodiment 3

[0030] Formulation example 3: 4.2% fenoxazone · florasulam (4:0.2) dispersible oil suspension concentrate

[0031] Pump 650 grams of soybean oil into the container, add 75 grams of nonylphenol polyoxyethyl ether, 73 grams of castor oil polyoxyethylene ether, and 70 grams of calcium dodecylbenzenesulfonate into the container, and then add 40 grams while stirring. Clofenac, 2 grams of florasulam, 90 grams of white carbon black. Then shear at high speed for 30 minutes to mix the materials evenly. Turn on the circulating water to control the sand mill temperature below 40 degrees, and the material is sand-milled until the fineness passes through a 325 mesh sieve to obtain a 4.2% oxafentrazone·flusulam (4:0.2) dispersible oil suspension concentrate.
