Embodiment 1
[0020] The production method of the water-dispersible granules of tebufenpyrad and metaflumizone in this embodiment is as follows: adding metaflumizone and tebufenpyr into the carrier, adding a surfactant therein, mixing, and pulverizing by a jet mill Finally, add water with a weight ratio of 15%, knead with a kneader, granulate with an extrusion granulator, dry in an oven, and sieve with a sieving machine to obtain a water-dispersible granule product.
[0021] The water dispersible granules of tebufenfen and metaflumizone of the present embodiment consist of the following components in weight percentage:
[0022] Tebufenfen 10%
[0023] Metaflumizone 10%
[0024] Surfactant 6.5%
[0025] Carrier balance
[0026] In this example, the weight ratio of the active ingredient tebufenfen to metaflumizone is 1:1. Dispersants and wetting agents are used as surfactants. The dispersant is polycarboxylate with a content of 2%; the wetting agent is sodium lauryl sulfate with a conten...
Embodiment 2
[0028] The difference between this example and Example 1 is that the water-dispersible granules of tebufenfen and metaflumizone in this example are composed of the following components by weight percentage:
[0029] Tebufenfen 10%
[0030] Metaflumizone 20%
[0031] Surfactant 6%
[0032] Carrier balance
[0033] In this example, the weight ratio of the active ingredient tebufenfen to metaflumizone is 1:2. Dispersants and wetting agents are used as surfactants. The dispersant is methyl naphthalene sulfonate formaldehyde condensate sulfate (NNO), with a weight content of 4%; the wetting agent is alkylphenol polyoxyethylene ether sodium sulfate, with a weight content of 2%. The carrier is white carbon black and ammonium sulfate, and the weight content of white carbon black is 5%.
Embodiment 3
[0035] The difference between this example and Example 1 is that the water-dispersible granules of tebufenfen and metaflumizone in this example are composed of the following components by weight percentage:
[0036] Tebufenfen 15%
[0037] Metaflumizone 25%
[0038] Surfactant 6.5%
[0039] Carrier balance
[0040] In this example, the weight ratio of the active ingredient tebufenfen to metaflumizone is 1:1.67. Dispersants and wetting agents are used as surfactants. The dispersant is polycarboxylate with a content of 2%; the wetting agent is sodium lauryl sulfate with a content of 4.5%; the carrier is white sugar and soluble starch, and the weight content of white sugar is 20%.
