Problems solved by technology

Organophosphorus pesticides and pyrethroid pesticides have been unable to effectively control potato beetles. At present, the agents used to control potato beetles, such as fipronil, imidacloprid, and acetamiprid, are also facing the emergence of resistance
[0004] For a long time, chemical control has been the main method for pests such as Chrysophyllidae. Vegetable farmers have sprayed a lot of pesticides, resulting in serious pesticide residues. The resistance of pests is increasing, and the control effect of many pesticides is not ideal.

Embodiment 1

[0025] Example 1: Compound toxicity test of metaflumizone and acetamiprid, thiacloprid or nitenpyram

[0026] 1. Toxicity determination of metaflumizone, acetamiprid and different ratios on flea beetle

[0027] Use insect dipping method. In the experimental field, collect lively and healthy adult flea beetles with finger tubes, 20 per tube, seal with double-layer gauze, place in shading for 4 hours, and set aside; take fresh Shanghai green leaves and soak them in water for 1-2 hours. For 2 hours, select the middle part of the same size to spread out the leaves, and dry them in the air; dip the leaves in the prepared medicinal solution for 10 seconds, take them out and dry them in the shade, hang them in the Erlenmeyer flask with paper clips for later use; replace the finger tubes with plastic Seal the seal with gauze, dip in the prepared medicinal solution for 5 seconds, take it out, blot the excess medicinal solution with absorbent paper, and then transfer the test insects t...

Embodiment 2

[0051] Example 2: The preparation method of 40.5% metaflumizone acetamiprid emulsifiable concentrate

[0052] 96% metaflumizone active drug 41.67g

[0053] 99% Acetamiprid Technical 0.51g

[0054] Sodium dodecylbenzenesulfonate (emulsifier) ​​7.2g

[0055] Phenylphenol ethoxylate (emulsifier) ​​2.4g

[0056] Toluene (solvent) make up to 100g

[0057] According to the formula requirements, mix and stir metaflumizone, acetamiprid, emulsifier, and part of the solvent in the preparation kettle. After the solid is completely dissolved, slowly add the remaining solvent, and after fully stirring, 100 grams of 40.5 % Metaflumizone·Acetamiprid EC (the mass ratio of Metaflumizone and Acetamiprid is 80:1).

Embodiment 3

[0058] Example 3: The preparation method of 40.5% metaflumizone imidacloprid water dispersible granules

[0059] 96% Metaflumizone 0.52g

[0060] 95% imidacloprid technical 42.11g

[0061] Calcium lignosulfonate (dispersant) 9.2 grams

[0062] Sodium lauryl sulfate (wetting agent) 3.4 g

[0063] Urea (disintegrant) 3.1g

[0064] Silica (carrier) make up to 100g

[0065] According to the formula requirements, various components such as metaflumizone and imidacloprid were weighed, first mixed and pulverized by air flow, then extruded and granulated, dried and sieved to obtain 100 grams of 40.5% metaflumizone imidacloprid water dispersion Granules (the mass ratio of metaflumizone and imidacloprid is 1:80).

Abstract

The invention relates to an insecticidal composition which contains effective constituents of metaflumizone and anabasine pesticide with a mass ratio of 80:1-1:80. The insecticidal composition has the advantage of synergistic effect and can reduce drug amount, delay the development of the drug resistance of pests and enlarge a control spectrum. The insecticidal composition can control coleopteran pests, the lepidopteran pests, homoptera pests, thysanoptera pests, and the like and particularly be applied to control phyllotreta striolata and potato beetles.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing metaflumizone. And the application of the composition in agricultural control. Background technique [0002] The flea beetle belongs to the family Coleoptera Chrysanthemum, and it is a worldwide pest that harms cruciferous vegetables, and it spreads all over the country. The flea beetle is overrun in many places where cruciferous vegetables are continuously cropped, resulting in extinction. The control of flea beetle has always been a big problem, mainly chemical control. [0003] The potato beetle, also known as the potato beetle, belongs to the family Coleoptera and is a destructive pest that harms tomatoes, peppers and other solanaceous vegetables. Organophosphorus pesticides and pyrethroid pesticides have been unable to effectively control potato beetles. At present, the agents for controlling potato beetles, such as fipronil, imidaclopr...
