specific Embodiment approach

[0030] The present invention will be further described below in conjunction with the examples, but the present invention is not limited thereto.

[0031] The embodiment of the present invention adopts the method that indoor bioassay and field test are combined. First, through indoor bioassays, the co-toxicity coefficient of the two agents compounded in a certain proportion is clarified, and on this basis, field experiments are being carried out.

Embodiment 1

[0039] Example 1: 70% spirodiclofen diafenthiuron wettable powder

[0040] 10g of spirodiclofen, 60g of diafenthiuron, 3g of sodium lauryl sulfate, 5g of alkylnaphthalene sulfonate formaldehyde condensate, 8g of white carbon black, and kaolin to make up to 100g, mix the above ingredients, and pulverize them with a jet mill to With a certain fineness, after testing and packaging, it becomes 70% spirodiclofen·diafenthiuron wettable powder.

[0041] In this embodiment, spirodiclofen can vary from 1 to 29 parts, and diafenthiuron can vary from 1 to 69 parts, but the total weight content of the two is 70%, forming a new embodiment.

Embodiment 2

[0042] Example 2: 80% spirodiclofen diafenthiuron water dispersible granules

[0043] 8g spirodiclofen, 72g diafenthiuron, 3g sodium dodecylbenzene sulfonate, 4g sodium lignin sulfate, 2g alkylnaphthalene sulfonate formaldehyde condensate, 5g urea, diatomaceous earth to 100g, the above formula Mix the materials evenly, pulverize them with an ultra-fine airflow mill, knead them, and then add them to a fluidized bed granulation dryer for granulation, drying, and sieving. After sampling and analysis, 80% spirodiclofen diafenthiuron water is made. Dispersible granules.

[0044]In this embodiment, spirodiclofen can vary from 1 to 29 parts, and diafenthiuron can vary from 1 to 79 parts, but the total weight content of the two is 80%, forming a new embodiment.

Abstract

The invention belongs to the technical field of pesticide, and in particular relates to an acaricidal composition containing spirodiclofen. An effective constituent of the composition consists of the spirodiclofen and diafenthiuron, and the weight ratio of the spirodiclofen and the diafenthiuron is 1-30 to 80-1. The composition is prepared into wettable powder, water dispersible granules, suspending agents, emulsifiable solutions, emulsions in water or micro-emulsions, is used for preventing and controlling harmful mites on fruit trees and cotton, and has the advantages of high drug effect, small dosage and the capability of deferring the harmful mites to have insecticide resistance.

Description

technical field [0001] The invention relates to a compound composition with acaricidal activity, in particular to an acaricidal composition compounded with spirodiclofen and diafenthiuron and has a synergistic effect, and belongs to the technical field of pesticides. Background technique [0002] The English name of spirodiclofen: (spirodiclofen), the chemical name is: 3-(2,4 dichlorophenyl)-2-oxo-1-oxo spiro[4.5]dec-3-en-4-yl-2, 2-Dimethylbutyrate, molecular formula: C 21 h 24 C 12 o 4 . Its structural formula is: [0003] [0004] Spirodiclofen is a brand-new, high-efficiency non-systemic foliar treatment acaricide, which has good control effect and excellent long-lasting effect on different types of mites in various crops. The mechanism of action of spirodiclofen is to inhibit the synthesis of fat in harmful mites, and it is effective on various developmental processes of mites (including eggs, larvae, nymphs, etc.) through contact action, especially the contact ...
