Embodiment 1

[0021] The suspension concentrate of tebufenfen and metaflumizone of the present embodiment is made up of the following components by weight percentage:

[0022] Tebufenfen 10%

[0023] Metaflumizone 10%

[0024] Surfactant 6%

[0025] water balance

[0026] In this embodiment, the weight content of the active ingredients tebufenfen and metaflumizone is 20%. Dispersants and wetting agents are used as surfactants. Sodium lignosulfonate and methyl naphthalene sulfonate formaldehyde condensate sulfate are selected as the dispersant, with a weight content of 3% and 2% respectively; nonylphenol polyoxyethylene ether is used as a wetting agent, with a weight content of 1%.

[0027] The production method of the suspending agent of tebufenpyrad and metaflumizone in this embodiment is that the active ingredients tebufenpyrad and metaflumizone are added to water, and then a surfactant is added, mixed, and wet through a vertical sand mill. Pulverize, and finally mix evenly to get th...

Embodiment 2

[0029] The difference between this example and Example 1 is that the suspension concentrate of tebufenfen and metaflumizone in this example is composed of the following components in weight percentage:

[0030] Tebufenfen 10%

[0031] Metaflumizone 20%

[0032] Surfactant 4.5%

[0033] water balance

[0034] The weight content of the active ingredients tebufenfen and metaflumizone in this example is 30%. Dispersants and wetting agents are used as surfactants. The dispersant is polycarboxylate with a weight content of 4%; the wetting agent is sodium lauryl sulfate with a weight content of 0.5%.

Embodiment 3

[0036] The difference between this example and Example 1 is that the suspension concentrate of tebufenfen and metaflumizone in this example is composed of the following components in weight percentage:

[0037] Tebufenfen 15%

[0038] Metaflumizone 25%

[0039] Surfactant 6%

[0040] water balance

[0041] In this embodiment, the weight content of the active ingredients tebufenfen and metaflumizone is 40%. Dispersants and wetting agents are used as surfactants. The dispersant is sodium N-methyl fatty acyl taurate, with a weight content of 5%; the wetting agent is pull-off powder, with a weight content of 1%.

Abstract

The invention belongs to the field of agricultural pesticides, and particularly relates to a tebufenpyrad / metaflumizone suspension agent and a production method thereof. The suspension agent comprises tebufenpyrad, metaflumizone, water and surfactant, wherein the weight percent of the effective ingredients of tebufenpyrad and metaflumizone is 10-50%. Preferably, the weight ratio of the effective ingredients of tebufenpyrad and metaflumizone is (10:1)-(1:10). Preferably, the weight ratio of the effective ingredients of tebufenpyrad and metaflumizone is 1:(1-3). The composition provided by the invention is mainly used for controlling mites, lepidoptera pests, 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 suspending agent of tebufenpyrad 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 (25-200mg(a.i...
