Problems solved by technology

In order to avoid the impact on the environment, it is necessary to reduce the amount of chemical insecticides. However, the use of low concentrations of insecticides promotes the increase of pest resistant species. In addition, it cannot guarantee that all pests are killed and their growth cycle is disrupted.

Embodiment 1

[0038] The formula of acaricide in suspension form: 20.66g of 96.8% acequinone former medicine, 2.11g of 95% pyridaben former medicine, 4g of sodium lignosulfonate (dispersant), 4g of ethylene glycol (antifreezing agent), bentonite (thickener) 3g, silicone oil (defoamer) 0.4g, deionized water to make up to 100g. In the acaricide formula, the content of acequinone·pyridaben suspension concentrate is 22 wt%, wherein the mass ratio of acequinone to pyridaben is 10:1.

[0039]The preparation method of the suspension-type acaricide in this example: mix the active ingredients acarquinone and pyridaben, dispersant, antifreeze agent, thickener, defoamer and water according to the ratio of the above formula and mix evenly. Suspension concentrates are prepared after sanding and / or high-speed shearing.

Embodiment 2

[0041] The acaricide formula of the suspension dosage form: 1.03g of 96.8% acequinone former medicine, 21.05g of 95% pyridaben former medicine, 4g of sodium lignosulfonate (dispersant), 4g of ethylene glycol (antifreezing agent), yellow Raw acid gum (thickener) 0.5g, silicone oil (defoamer) 0.4g, deionized water to make up to 100g. In the acaricide formula, the content of acequinone·pyridaben suspension concentrate is 21 wt%, wherein the mass ratio of acequinone to pyridaben is 1:20.

[0042] The preparation of the suspension type acaricide of this example is prepared with reference to the preparation method of Example 1.

[0043] Comparative test 1

[0045] The above-mentioned 4 kinds of medicament acaricides are carried out the mensur...

Embodiment 3

[0047] Oil-suspended acaricide formula: 20.66g of 96.8% methquinone technical, 2.11g of 95% pyridaben technical, 10g of sodium lignosulfonate (wetting and dispersing agent), styrylphenol polyoxyethylene ether (emulsifier) ​​5g, bentonite (thickener) 5g, organosilicone (defoamer) 5g, refined soybean oil to 100g. In the acaricide formula, the content of acequinone·pyridaben suspension concentrate is 22 wt%, wherein the mass ratio of acequinone to pyridaben is 10:1.

[0048] The preparation method of the oil-suspended acaricide in this example: mix the active ingredients acarquinone and pyridaben, dispersants, emulsifiers, stabilizers, defoamers and solvents according to the ratio of the formula, and put them into After being ground in a sand mill, it is sent into a homogeneous mixer and mixed to obtain the finished product.

Abstract

The invention provides an acaricide, which contains the effective components of acequinocyl and pyridaben that are in a mass ratio of 50:1-1:100. In the invention, mutual blending of the components acequinocyl and pyridaben effectively improves the synergistic effect of the acaricide, and significantly enhances the control effect of the acaricide on target pest mites. Due to the excellent synergistic effect of the acaricide, the efficacy of the acaricide is improved, the field dosage of the acaricide is reduced, the pesticide residue and the harm on beneficial organisms can be effectively reduced, and simultaneously, the control cost is lowered and the environmental pollution is alleviated. The acaricide of the invention makes fully use of the respective function mechanism of the components acequinocyl and pyridaben to make the two components has a synergistic effect, so that the acaricide can effectively delay or overcome the drug resistance of pest mites.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, in particular to an acaricide and its application. Background technique [0002] Acarids belong to the class Arthropoda. Herbivorous mites mainly include spider mites, panonychia, gall mites, rust mites, etc. They are common pests that harm vegetables, fruit trees, cotton and other crops, often causing devastating disasters. Agriculturally important pest mites are particularly prone to drug resistance due to their short reproductive cycle, large reproductive capacity, low mobility, and high degree of self-fertilization. [0003] At present, the control of pests of the Arthropoda phylum is becoming more and more difficult. This is mainly due to the resistance of pests to the insecticides used and the impact on the environment caused by increased concentrations of insecticides. In order to avoid impact on the environment, it is necessary to reduce the amount of chemical insecticides used. H...
