Abstract

The invention discloses a compound insecticide, which relates to an insecticide. The purpose of the invention is to provide a compound insecticide with good effect on killing scale insects and low toxicity. The technical scheme of the present invention is that a compound insecticide includes quick culling, emulsifier, solvent, acetamiprid and synergist, and the weight percentage of each component is: 10-20% of quick culling, Acetamiprid 1.5-2%, emulsifier 8-10%, synergist 2%, and the balance is solvent. The emulsifier is 0201B, the solvent is xylene, and the synergist is azone. The invention is used for controlling scale insects.

Description

a compound insecticide

Technical field:

The invention relates to an insecticide, in particular to a compound insecticide for controlling scale insects.

Background technique:

At present, the area of domestic fruit trees and flowers is increasing, and the prevention and control of scale insects on these plants has become the biggest problem for relevant technical personnel. The current situation of scale insect control and use is: most pesticides have poor control effects on scale insects, and only quick culling has a good effect on scale insects. Greater impact. There have been people in China who compounded quick culling and other pesticides in an attempt to reduce the dosage of quick culling without reducing the efficacy, thereby reducing toxicity (Xu Jianjun 1995, Ren Xiaozhou et al. 2000, Huang Hongying et al. 2003), but The effects are not ideal. Therefore, in the prevention and control of scale insects, there is not yet a kind of ideal insecticide.

Invention content:

The purpose of the present invention is to provide a compound insecticide with good effect on killing scale insects and low toxicity. The technical scheme of the present invention is, a kind of composite insecticide, comprises quick culling and emulsifier, solvent, is characterized in that: also contains acetamiprid and synergist, and the weight percentage of each composition is: quick culling 10 -20%, acetamiprid 1.5-2%, emulsifier 8-10%, synergist 2%, and the balance is solvent. The emulsifier is 0201B, the solvent is xylene, and the synergist is azone. Compared with the prior art, the invention has the remarkable advantages of good scale insect control effect and low toxicity.

Detailed ways:

The present invention has following embodiment:

Example 1:

Wherein the percentage by weight of the active ingredients is: quick culling 10%, acetamiprid 2%, emulsifier (0201B 10%), synergist (azone 2%), solvent (the amount of xylene is the balance) 76% . First add part of the solvent to the preparation tank, and then under the condition of agitation, according to the conventional usage amount added in turn, add quick kill, acetamiprid, emulsifier and other auxiliary agents and the remaining solvent to obtain the present invention Compound insecticides.

Example 2:

Wherein the percentage by weight of the active ingredient is: quick culling 15%, acetamiprid 1.75%, emulsifier (0201B10%), synergist (azone 2%), solvent (the amount of xylene is the balance) 71.25% . First, most of the solvents are added to the preparation tank, and then under the condition of stirring, according to the conventional usage amount added in turn, add quick culling, acetamiprid, emulsifiers and other auxiliary agents and the remaining solvents to obtain the present invention Compound insecticides.

Example 3:

Wherein the percentage by weight of the active ingredient is: quick culling 20%, acetamiprid 1.5%, emulsifier (0201B10%), synergist (azone 2%), solvent (the amount of xylene is the balance) 66.5% . First, most of the solvents are added to the preparation tank, and then under the condition of stirring, according to the conventional usage amount added in turn, add quick culling, acetamiprid, emulsifiers and other auxiliary agents and the remaining solvents to obtain the present invention Compound insecticides.

The use method of the insecticide of the present invention is: for the scale insects on the fruit trees and flowers, apply the medicine at the peak stage of the newly hatched nymphs of the scale insects, and use the insecticide of the present invention mixed with 1000 times of water to spray the stems and leaves, and must be sprayed evenly. The water consumption is: 100 kilograms per mu for orchards in full fruit period, 50-60 kilograms per mu for plants and flowers, and about 75 kilograms per mu for shrubs and flowers. If the older nymphs of scale insects are controlled, an 800-fold dilution can be used. Water consumption is the same as above.

Control effect of the present invention sees the following table

Table 1 Key effect test of compound insecticides against scale insects (attached)

Compared with the prior art, the present invention has the following advantages

(1) The control effect on scale insects is better than quick culling, and the control effect is more than 90%;

(2) This product is moderately toxic and can be used in urban green spaces and orchards;

(3) After several years of experiments in more than 200,000 mu of fruit trees and flower fields, the performance in the field is stable.

Claims (2)

1, a kind of composite insecticide, comprises quick culling and emulsifier, solvent, is characterized in that: also contains acetamiprid and synergist, and the weight percent of its each composition is: quick culling 10-20%, pyridine Chlorochlorid 1.5-2%, emulsifier 8-10%, synergist 2%, and the balance is solvent. 2. A compound insecticide according to claim 1, characterized in that: the emulsifier is 0201B, the solvent is xylene, and the synergist is azone.
