Embodiment 1

[0050] Embodiment 1: 23.2% amitraz Buprofezin emulsion in water (1:45.4)

[0051] Amitraz 0.5%, buprofezin 22.7%, cyclohexanone 3.5%, xylene 7.0%, emulsifier 7.0%, urea 4.5%, defoamer 0.1%, water to make up to 100%.

[0052] Preparation method: Dissolve the original drug in a solvent, add an emulsifier and mix evenly, then add water and stir until a clear and transparent liquid is formed to obtain a 23.2% amitraz·buprofezin aqueous emulsion.

Embodiment 2

[0053] Example 2: 34% amitraz Buprofezin microemulsion (1:33)

[0054] Amitraz 1%, buprofezin 33%, calcium dodecylbenzenesulfonate 4%, styrylphenol polyoxyethylene ether 10%, castor oil polyoxyethylene ether 4%, cyclohexanone 18%, three Toluene 12%, water make up 100%.

[0055] Preparation method: Dissolve the original drug in a solvent, add an emulsifier and mix evenly, then add water and stir until a clear and transparent liquid is formed, and then a 34% amitraz·buprofezin microemulsion can be prepared.

Embodiment 3

[0056] Example 3: 24% Amitraz Buprofezin Water Dispersible Granules (1:23)

[0057] Amitraz 1%, Buprofezin 23%, Sodium Lauryl Sulfate 1.5%, Sodium Lignosulfonate 8%, Starch 6%, Kaolin supplement 100%.

[0058] Preparation method: Mix the original drug, auxiliary agents and fillers uniformly, then perform jet crushing, wet granulation and drying to obtain 24% amitraz·buprofezin water-dispersible granules.

Abstract

The invention discloses an insect and mite killing composition and application thereof, and relates to the technical field of pesticide compounding. The insect and mite killing composition comprises an effective component A and an effective component B, wherein the effective component A is amitraz; the effective component B is dibenzoyl-1-tert-butylhydrazine; the weight ratio of the effective component A to the effective component B is (1:60)-(70:1). The insect and mite killing composition is reasonable in proportioning, has a remarkable synergism function, is excellent in effect on lepidoptera pests and agriculture mites such as plutella xylostella, prodenia litura, tetranychus cinnabarinus and two-spotted spider mites particularly, is capable of effectively reducing the administration amounts of single agents, has the purposes of retarding drug resistance and lowering cost, and has remarkable application and popularization values.

Description

technical field [0001] The present invention relates to an insecticidal and acaricidal composition and its application, in particular to an insecticidal and acaricidal composition containing amitraz as an active ingredient and insect growth-regulating insecticides such as buprofezin or hydrazine. The application thereof belongs to the technical field of pesticide compounding. Background technique [0002] In the actual process of agricultural production, chemical control is still the most effective means of controlling pests, but due to the continuous and large-scale use of chemical insecticides, the problem of pest resistance has become increasingly prominent. Moreover, the pests that are prone to resistance to pesticides are usually those with large reproduction numbers and obvious overlapping generations. Such as planthoppers, aphids, spider mites, diamondback moths, etc. [0003] Amitraz is a broad-spectrum acaricide with multiple poisoning mechanisms, mainly inhibitin...
