Embodiment 1

[0043] The present invention contains the emulsifiable concentrate preparation of the high-efficiency insecticide of tebufenpyrad, cyromazine and transfluthrin, and the specific composition is as follows (1000g per part):

[0044] Tebufenpyrad: 10 parts; Cyromazine: 20 parts; Transfluthrin: 20 parts;

[0045] The specific production steps of the emulsifiable concentrate preparation are first adding the active ingredients tebufenpyrad, cyromazine and transfluthrin into the solvent according to the conventional procedures in the field to completely dissolve, then adding emulsifiers and synergists and stirring evenly to form a uniform product. The transparent oily liquid can be filled into an emulsifiable concentrate preparation of the composition of the present invention.

Embodiment 2

[0047] The present invention contains the suspending agent of the high-efficiency insecticide of tebufenpyrad, cyromazine and transfluthrin, and the specific composition is as follows (every part of 1000g):

[0048] Tebufenpyrad: 50 parts; Cyromazine: 40 parts; Transfluthrin: 60 parts;

[0049] The specific production steps of this suspending agent are the conventional suspending agent preparation method in the art, first other auxiliary agents (dispersant, antifreeze agent, thickener, defoamer, penetration enhancer and pH value regulator) are mixed, Shear and mix evenly, add the active ingredients tebufenpyrad, cyromazine and transfluthrin, and grind the balls in a ball mill for 2 to 4 hours, so that the particle diameters are all below 5mm, and the combination of the present invention can be made suspension formulations.

Embodiment 3

[0051] The present invention contains the water-dispersible granule of the high-efficiency insecticide of tebufenpyrad, cyromazine and transfluthrin, and the specific composition is as follows (1000g per part):

[0052] Tebufenpyr: 35 parts; Cyromazine: 30 parts; Transfluthrin: 40 parts.

[0053] The specific production steps of the water-dispersible granules are the conventional preparation methods of water-dispersible granules in the art: according to the above formula, the active ingredients tebufenpyrad, cyromazine, flufenthrin, dispersant, wetting agent, disintegrant The solution and the filler are mixed evenly, pulverized with an ultra-fine jet mill, kneaded, then added to a fluidized bed granulation dryer for granulation, drying, and sieving. After sampling and analysis, the composition of the present invention can be prepared. Water dispersible granules.

[0054] The medicaments prepared in Examples 1-3 of the present invention were tested in a field, and their contro...

Abstract

The invention discloses a high-efficiency insecticide containing tebufenpyrad, cyromazine and transfluthrin and relates to a high-efficiency insecticide composition used for killing agricultural insects. The high-efficiency insecticide comprises the following components in parts by weight: 10-50 parts of tebufenpyrad, 20-40 parts of cyromazine and 20-60 parts of transfluthrin. The high-efficiency insecticide disclosed by the invention has the advantages that the insecticidal composition disclosed by the invention has an obvious synergistic effect, the amount of active ingredients can be reduced, the using cost is reduced, the drug resistance of the insects is delayed, the environmental pollution and pesticide residues are effectively reduced, and the insecticide has obvious effects of killing insects such as tetranychidae (panonychus ulmi, panonychus citri, tetranychus urticae and tetrangychus cinnabarinus), tarsonemidae (polyphagotarsonemus latus), eriophyidae (aculus schlechtendali and grape blister mite), tenuipalpidae (flat mite), aphididae (green peach aphid, cotton aphid and aphis pomi) and aleyrodidae (cassava whitefly); and meanwhile, destruction of the environment can be reduced.

Description

technical field [0001] The invention relates to the field of insecticides used for the control of agricultural pests, in particular to a high-efficiency insecticide containing tebufenpyrad, cyromazine and transfluthrin. Background technique [0002] The residues of pesticides in agricultural products and the toxicity to animals have always been a hot spot of concern. [0003] Tebufenfen: [0004] Chinese aliases: ruling, Zhimite [0005] English name: Tebufenpyrad [0006] Chemical name: N-(4-tert-butylbenzyl)-4-chloro-3-ethyl-1-methylpyrazol-5-ylcarboxamide [0007] Molecular formula: C18H24CLN3O [0008] Structural formula: [0009] [0010] Toxicity: Non-toxic to bees, highly toxic to fish, care must be taken when using it. [0011] Tebufenpyrad is an amide acaricide, which has excellent effects on various mites and pests of Hemiptera and Homoptera, while Dandan has quick-acting and high-efficiency effects on all growth stages of mites, and has a long-lasting eff...
