Embodiment 1

[0033] 1) Research on the control effect of dipropacyclopyrid and pymetrozine on pests (indoor toxicity test)

[0034] 1. Drugs to be tested: the original drug of dipropacyclofen, the original drug of pymetrozine. Dissolve the original drugs of dipropacyclotran and pymetrozine in acetone, and make a mother solution of 10000 μg / kg, and store them in the refrigerator at 4°C for later use.

[0035] 2. Insects to be tested: Cereal aphid and Greenhouse Whitefly.

[0036] 3. Determination method:

[0037] The toxicity of dipropacyclopyrid, pymetrozine and their mixed preparations was determined by the glass tube drug film method with the corn aphid and greenhouse whitefly as test materials.

[0038] Single-dose toxicity assay method:

[0039] Using the glass tube drug film method, the test agents (including dipropacyclofen and pymetrozine) were first prepared with acetone into 7 concentration gradients of 0.01, 0.02, 0.04, 0.08, 0.16, 0.32, and 0.64 mg / kg. Draw 200 μ L from the ...

Embodiment 2

[0063] Example 2 22% Dipropacyclopyrid · Pymetrozine wettable powder

[0064] Components are composed as follows (each component is by weight percentage):

[0065] Dipropiprene 2%, pymetrozine 20%, sodium alkylnaphthalene sulfonate formaldehyde condensate (dispersant) 2%, sodium lignosulfonate (dispersant) 3%, sodium lauryl sulfate (moisturizer) Wet agent) 3%, white carbon black (filler) 20%, kaolin (filler) make up to 100%.

[0066] The preparation method is as follows: the above-mentioned active components, various auxiliary agents and fillers are fully mixed in proportion, and the mixture is pulverized by a superfine pulverizer to obtain a 22% dipterapram-pymetrozine wettable powder.

[0067] This embodiment is applied to the control of wheat aphids and tomato whitefly, and in the early stage of hair growth, different concentrations are mixed with water and sprayed. The control effect is shown in Table 5 below.

[0068] Table 5 The field effects of different preparations...

Embodiment 3

[0071] Example 3 16% Dipropterap-Pymetrozine Suspension Concentrate

[0072] Components are composed as follows (each component is by weight percentage):

[0073] Dipropetrin 1%, pymetrozine 15%, alkyl naphthalene sulfonate sodium formaldehyde condensate (dispersant) 5%, castor oil polyoxyethylene ether (emulsifier) ​​3%, fatty alcohol polyoxyethylene ether ( Emulsifier) ​​5%, sodium methylene bis-naphthalene sulfonate (wetting agent) 3%, xanthan gum (thickener) 2%, glycerol (antifreezing agent) 4%, water is added to 100%.

[0074] The preparation method is as follows: fully mix the active components, various additives and water in proportion, put them into a sand mill, grind to a particle size of 5 μm, and prepare a 16% diproterap-pymetrozine suspension concentrate.

[0075] This embodiment is used to prevent and control wheat aphids and tomato whitefly, and enter the early peak period of pest occurrence, and spray with different concentrations of water. The control effect ...

Abstract

The invention discloses an insecticidal composition containing afidopyropen and pymetrozine and application of the composition, and belongs to the technical field of a compound pesticide. The insecticidal composition is prepared from the active ingredients of afidopyropen, pymetrozine, and the active ingredients of afidopyropen and pymetrozine have a weight percent of 1:50 to 50:1, preferably, 1:20 to 20:1, more preferably 1:2 to 1:20. The mass percentage of afidopyropen and pymetrozine in the insecticidal composition is 1% to 95%, preferably 10% to 80% of the total. For the insecticidal composition, the active ingredients of afidopyropen and pymetrozine have completely different action mechanisms, and the compounding can synergistically increase the effect to pests, improve the preventioneffect, reduce the pesticide usage, delay the generation of the drug resistance, and reduce the risk. The insecticidal composition has significant prevention effects on sucking mouthparts pests suchas wheat aphid, cotton aphid, tomato whitefly, laodelphax striatellus and empoasca vitis.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and in particular relates to an insecticidal composition containing dipropacyclofen and pymetrozine and an application thereof. Background technique [0002] In recent years, with the changes in farming and cultivation systems, the occurrence of pests has increased year by year, and crop yield and quality have been seriously affected. Chemical insecticide is the most economical and effective means of pest control. The application of insecticides to control pests is of great significance in recovering crop yield losses and improving the commerciality and quality of agricultural products. [0003] Dipropyrene is an insecticide with a novel structure and mechanism of action jointly developed by Japan’s Meiji Pharmaceutical Co. Quick-acting, high-efficiency, and long-lasting, it can be used to control small pests on field crops, vegetables, fruit trees, and ornamental plants. It can be...
