Embodiment 1
[0062] Example 1: 18.3% Amitraz · Flubenzuron Suspension Concentrate (1:60)
[0063] Amitraz 0.3%, Flubenzuron 18%, Alkylphenol Polyoxyethylene Phosphate 5%, Polyoxyethylene Polyoxypropylene Ether Block Copolymer 3%, Ethylene Glycol 5%, Xanthan Gum 0.15% , silicone defoamer 0.1%, Kasone 0.5%, water to make up to 100%.
[0064] Preparation method: Mix the components, mix them uniformly by high-speed shearing, and then sand them with a sand mill for 2-3 hours, so that the average particle size reaches 1-5 microns, and then you can prepare 18.3% amitraz · fluorobenzene Urea suspension.
Embodiment 2
[0065] Example 2: 26% amitraz·flufenuron EC (1:25)
[0066] Amitraz 1%, Flubenzuron 25%, Nongru 500 # 2.5%, Nongru 605 # 3.5%, trimethylbenzene make up to 100%.
[0067] Preparation method: mix the raw materials of each component in proportion, fully dissolve in trimethylbenzene, and then add an emulsifier to obtain a clear and transparent 26% amitraz·flubenzuron emulsifiable concentrate.
Embodiment 3
[0068] Example 3: 33% Amitraz · Flubenzuron Water Dispersible Granules (1:10)
[0070] Preparation method: Mix the original drug, additives and fillers uniformly, and then perform jet crushing, wet granulation, and drying to prepare 33% amitraz·flubenzuron water-dispersible granules.

Abstract
The invention discloses a pesticidal and acaricidal composition and application thereof, and relates to the technical field of pesticide mixing. The pesticidal and acaricidal composition is prepared from an effective component A and an effective component B, the effective component A is amitraz, the effective component B is benzoylurea insecticide, and the weight ratio of effective component A to the effective component B is 1:60-70:1. The mixed preparation is reasonable in matching, has a remarkable synergistic effect, particularly has an excellent effect on lepidoptera pests such as plutella xylostella and prodenia litura as well as agricultural acarid such as tetranychus cinnabarinus and tetranychus urticae, can effectively reduce application amount of all single agents, achieves the purposes of delaying pesticide resistance and reducing cost and has obvious application and popularization value.
Description
technical field [0001] The invention relates to an insecticidal and acaricidal composition and its application, in particular to an insecticidal and acaricidal composition containing active ingredients amitraz and benzoylurea insecticides and its application, which belongs to the compounding of pesticides technology field. 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 inhibiting the activity of monoamine oxidase, having contact ki...
