Embodiment 1

[0084] Diniconazole technical drug (solid) 2%, thiram technical drug (solid) 13%, lignosulfonate: 1.5%, alkyl aryl polyoxyethylene ether: 2%; hydroxymethyl cellulose: 8% ; Organosilicone: 3%; polyvinyl acetate emulsion: 6%; the remaining amount of water, according to the ratio of diniconazole: thiram = 1:6.5 to make a suspension seed coating agent, the process is: first use airflow After the pulverizer initially pulverizes thiram and diniconazole to about 50 meshes, add other weighed ingredients to mix thoroughly, grind three times with a sand mill, and check with a particle size analyzer. Up to less than 3μm.

Embodiment 2

[0086] Diniconazole (solid) 4%, Mancozeb (solid) 26%, polyoxyethylene polyoxypropylene ether block copolymer: 2.5%, alkylphenol polyoxyethylene ether phosphate: 4 %; aluminum magnesium silicate: 6%; organosilicone: 4%; bubble release: 6%; water balance, according to the ratio of diniconazole: mancozeb = 1:6.5 to make a suspension seed coating agent The process is as follows: first use a jet mill to pulverize thiram and diniconazole solid technical materials to about 50 meshes, then add other weighed ingredients to mix thoroughly, and grind three times with a sand mill , Check with a particle size analyzer, the particle size is less than 3μm.

Embodiment 3

[0088] Diniconazole original drug (solid) 5%, Zinc dysenteric original drug (solid) 32.5%, polyoxyethylene ether: 3.5%, sodium dodecylbenzene sulfonate: 6%; xanthan gum: 10%; organic Silicone: 5%; bubble release: 8%; water balance, according to the ratio of diniconazole: dysenzine = 1:6.5 to make a suspension seed coating agent, the process is: first use a jet mill to After thiram and diniconazole solid technical material are initially crushed to about 50 mesh, add other weighed ingredients and mix them thoroughly, grind it with a sand mill three times, and check with a particle size analyzer until the particle size is less than 3μm. .
