Embodiment 1

[0020] The water-dispersible granules of tebufenfen and metaflumizone of the present embodiment are composed of the following components in weight percent:

[0021] Tebufenfen 10%

[0022] Metaflumizone 10%

[0023] Surfactant 6.5%

[0024] Carrier balance

[0025] 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 content of 4.5%; the carrier is white sugar and soluble starch, and the weight content of white sugar is 20%.

[0026] 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 gr...

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%.

Abstract

The invention belongs to the field of agricultural pesticides, and particularly relates to a tebufenpyrad / metaflumizone water dispersible granule. The tebufenpyrad / metaflumizone water dispersible granule comprises the effective ingredients of tebufenpyrad and metaflumizone, wherein the weight percent of the tebufenpyrad is 1-20%, and the tebufenpyrad / metaflumizone weight ratio is 1:(1-3); and other ingredients include a carrier and surfactant. The composition provided by the invention is mainly used for controlling lepidoptera pests, mites, aphides, whiteflies and the like on fruit trees, vegetables and grain crops. The composition has the characteristics of effect improvement, pesticidal range widening, pest drug resistance delaying, high crop safety and the like.

Description

technical field [0001] The invention belongs to the field of agricultural insecticides, in particular to a water-dispersible granule of tebufenfen and metaflumizone and a production method thereof. Background technique [0002] Tebufenpyramid is an amide acaricide. It has excellent effects on various mites and pests of Hemiptera and Homoptera, and has quick-acting and high-efficiency effects on all growth stages of mites, and has a long-lasting effect, such as Tetranychidae (Planyonychus apple, Panonychus citrus, cotton Tetranychus, Tetranychus cinnabarinidae, etc.), Tarsidae (lateral tarsal mites), Eriodidae (apple rust mite, grape rust mite, etc.), Styropterygidae (Grape mite), Aphididae ( Peach aphid, cotton aphid, apple aphid), whitefly family (cassava whitefly). No cross-resistance with dicofol, fenbutatin, thiazofen, etc. No systemic, but osmotic activity, excellent selectivity to the target crops, no phytotoxicity to most crops under the recommended dose (25-20...
