Technical Field

The invention belongs to the field of insecticides and acaricides, and relates to an insecticidal and acaricidal composition.

Background

The insecticidal and acaricidal agent has obvious effect on preventing and controlling agricultural and forestry pests or urban sanitary pests.

The Chinese patent CN105541682 discloses a biphenyl compound and application thereof in controlling insect pests and mite pests, wherein the compound 1 (hereinafter referred to as compound I) can be used for controlling various pests and mites, and particularly has an outstanding control effect on the pest mites.

The insecticide and acaricide containing single active component can be continuously used for preventing and controlling pests, and is easy to cause the pests to generate drug resistance. The insecticide and acaricide with two active components are mixed into a mixed component according to a certain proportion, so that the control effect can be improved, the using amount of active components is reduced, the cost is saved, and the generation of drug resistance of pests can be delayed.

Although numerous binary insecticidal and acaricidal compositions containing compound I are generally disclosed in the prior art, no specific disclosure is made of the technical scheme of binary insecticidal and acaricidal compositions containing compound I and an insecticidal/acaricidal agent of the mitochondrial electron transport complex class (I) or (III).

Disclosure of Invention

The invention aims to provide an insecticidal and acaricidal composition in order to meet the requirements of increasing the effect of insecticidal and acaricidal agents and continuously updating varieties in the aspect of preventing and controlling pests in the fields of agriculture, forestry and urban sanitation.

In order to achieve the purpose, the invention adopts the technical scheme that:

an insecticidal and acaricidal composition comprises an active component A and an active component B, wherein the weight part ratio of the active component A to the active component B is 1: 99-99: 1; the active component A is selected from a compound I, and the active component B is selected from a mitochondrial electron transfer complex (I) inhibitor insecticide/acaricide or a mitochondrial electron transfer complex (III) inhibitor insecticide/acaricide;

the active component A compound I has the following structure:

the active component B is selected from mitochondrial electron transfer complex (I) inhibitor insecticides/acaricides including pyridaben, fenpyroximate, pyriminostrobin, tebufenpyrad, pyrazofen, tolfenpyrad or rotenone; the mitochondrial electron transport complex (III) inhibitor insecticide/acaricide comprises flufenarimate, pyriminostrobin, Flometoquin, hydramethylnon or diafenthide.

The active component A is a compound I, and the active component B is pyridaben or Flomesoquin; the weight part ratio of the active component A to the active component B is 50:1-1: 50.

The active component A is a compound I, and the active component B is fenpyroximate, fluacrypyrim or pyriminostrobin; the weight part ratio of the active component A to the active component B is 20:1-1: 40.

The active component A is a compound I, and the active component B is selected from pyridaben, fenpyroximate, fluacrypyrim, pyriminostrobin or Flomesoquin; the weight part ratio of the active component A to the active component B is 10:1-1: 10.

The active component A is a compound I, and the active component B is selected from pyridaben, fenpyroximate, fluacrypyrim, pyriminostrobin or Flomesoquin; the weight part ratio of the active component A to the active component B is 4:1-1: 4.

Further, the composition is mixed with a carrier and any one of the auxiliary agents to prepare a preparation containing the composition.

The cumulative content of active ingredients of the composition in the preparation is between 0.5 wt% and 95 wt%. Preferably, the cumulative amount of active ingredient in the formulation is between 1% and 85%.

The application of a pesticide-miticide composition in preparing pesticide-miticide for controlling agricultural pests or urban sanitary pests.

The above records are particularly suitable for controlling various important agricultural pests such as tetranychus cinnabarinus, tetranychus hawthorn, panonychus citri, rust citrus mite, tetranychus ulmi, tetranychus urticae koch, gall mite, tetranychus urticae koch and the like. It can be used for fruit trees such as apple, pear, citrus, and litchi, cereals such as wheat and rice, beans such as soybean and kidney bean, cotton, and vegetables such as cabbage, cauliflower, Chinese cabbage, rape, tomato, pepper, and flowers. When the insecticidal composition is used for preventing and controlling urban pests, the insecticidal composition can be used for families, various public places, office places, trees and the like.

Further, the method for using the insecticidal and acaricidal composition is to apply the prepared insecticidal and acaricidal agent to the pests to be controlled or the medium for growing the pests by using the effective dosage. Preferably, an effective dose of 10 g to 500 g per hectare is generally selected, preferably an effective dose of 15 g to 100 g per hectare.

The invention has the following advantages:

1. the composition of the invention shows obvious synergistic effect on insect and mite killing in a certain proportion range, and improves the control effect of a single active ingredient compound in the composition on pests.

2. The dosage of the composition applied to killing insects and mites is obviously lower than that of a single compound in the composition, so that the use cost is reduced, and the environmental pollution is reduced.

3. The effective components in the composition have different action mechanisms in the processes of killing insects and mites, so that the problem of cross resistance does not exist, the occurrence of drug resistance of pests can be delayed by using the composition to control the pests, and the control effect on resistant populations is improved.
