Embodiment 1

[0030] The preparation method of the solvent-free difenoconazole propiconazole suspoemulsion of this embodiment comprises the following steps:

[0031] 1. Heat 150g of propiconazole to 61°C, then add 40g of emulsifier, stir evenly, then add 742g of water to shear to obtain propiconazole in water emulsion, and keep the prepared propiconazole in water emulsion at 61°C;

[0032] 2. Heat 50g of difenoconazole to 85°C and melt into a liquid;

[0033] 3. Add 15g dispersant, 2g defoamer and difenoconazole melted into liquid to the propiconazole aqueous emulsion prepared in step 1, continue to shear for 15min, and cool rapidly to normal temperature to obtain difenoconazole Cycloconazole propiconazole suspoemulsion.

Embodiment 2

[0035] The preparation method of the solvent-free difenoconazole propiconazole suspoemulsion of this embodiment comprises the following steps:

[0036] 1. Heat 10g of propiconazole to 65°C, then add 20g of emulsifier, stir evenly, then add 728g of water to shear to obtain propiconazole water emulsion, and keep the prepared propiconazole water emulsion at 65°C;

[0037] 2. Heat 150g of difenoconazole to 82.5°C and melt into a liquid;

[0038] 3. Add 40g dispersant, 50g defoamer and difenoconazole melted into liquid to the propiconazole aqueous emulsion prepared in step 1, continue to cut for 16min, and cool rapidly to normal temperature to obtain difenoconazole Cycloconazole propiconazole suspoemulsion.

Embodiment 3

[0040] The preparation method of the solvent-free difenoconazole propiconazole suspoemulsion of this embodiment comprises the following steps:

[0041] 1. Heat 180g of propiconazole to 60°C, then add 50g of emulsifier, stir evenly, then add 736g of water to shear to obtain propiconazole water emulsion, and keep the prepared propiconazole water emulsion at 60°C;

[0042] 2. Heat 10g of difenoconazole to 81°C and melt into a liquid;

[0043] 3. Add 20g dispersant, 1g defoamer and difenoconazole melted into liquid to the propiconazole aqueous emulsion prepared in step 1, continue shearing for 17.5min, and rapidly cool to normal temperature to obtain phenyl ether Meconazole propiconazole suspoemulsion.
