[0019] 1. Example 1.20% fenflumezone·clodinafop-propargyl dispersible oil suspension concentrate (1:1)
[0020] Mefentrazone 10%
[0021] Clodinafop-propargyl 10%
[0022] Detoxacin 3%
[0023] Silica 2%
[0024] Propylene Glycol 5%
[0025] Hydrogenated castor oil ethylene oxide condensate 7%
[0026] Fatty alcohol polyoxyethylene ether 10%
[0027] Methyl oleate balance
[0028] The processing steps of the dispersible oil suspension concentrate are as follows: mix the oil dispersant, thickener, and emulsifier according to the above formula, mix evenly for 30 minutes through high-speed shearing, add fentrazone and clodinafop-propargyl, continue shearing and mixing 30min, and then enter into the horizontal sand mill to grind, so that the particle size of the preparation is all below 10 microns, and the dispersible oil suspension concentrate whose active ingredient content is 20% fentrazone-clodinafop-propargyl is prepared.

[0029] 2. Example 2: 20% fenflumezone·clodinafop-propargyl wettable powder (1:3)
[0030] Mefentrazone 5%
[0031] Clodinafop-propargyl 15%
[0032] Detoxacin 4%
[0033] Calcium lignosulfonate 2%
[0034] Alkyl naphthalene sulfonate formaldehyde condensate 5%
[0035] Sodium Lauryl Sulfate 6%
[0036] Silica 8%
[0037] Diatomaceous earth balance
[0038] The processing steps of the wettable powder are as follows: mix fentrazone, clodinafop-propargyl, dispersant, wetting agent and filler according to the above formula, stir evenly in a stirring tank, and mix evenly after being pulverized by ultra-fine airflow, that is, The wettable powder of fenfentrazone-clodinafop-propargyl with an active ingredient content of 20% can be prepared.
Embodiment 3
[0039] 3. Example 3: 24% fenflumezone·clodinafop-propargyl water dispersible granules (2:10)
[0040] Mefentrazone 4%
[0041] Clodinafop-propargyl 20%
[0042] Detoxacin 5%
[0043] Alkyl naphthalene sulfonate formaldehyde condensate 2%
[0044] Sodium Lauryl Sulfate 5%
[0045] Copolymer of butenedioic acid and styrene 1%
[0047] Diatomaceous earth balance
[0048] The processing steps of the water-dispersible granules are as follows: uniformly mix fentrazone, clodinafop-propargyl, dispersant, wetting agent, disintegrating agent and filler according to the above formula, pulverize with an ultra-fine jet mill, and knead. Then enter the extruding granulator to granulate, dry in the boiling dryer, and after sieving, through sampling and analysis, the fenflumezone-clodinafop-propargyl water-dispersible granule with an active ingredient of 24% is obtained.
