Embodiment 1

[0058] [1] This embodiment provides a composition that can reduce the hydrophilicity of the egg-stage pest shell, wherein the composition includes:

[0059] (a) compounds of the present invention having structural formula (1):

[0060] (b) plant extract of the present invention;

[0061] (c) surfactants of the present invention;

[0062] (d) organic solvents of the present invention; and

[0063] (e) Buffers of the present invention.

[0064] The composition of the present invention that can reduce the hydrophilicity of the shell layer of pests in the egg stage has a stable liquid phase structure, no stratification, no sedimentation, no organic phosphorus, sulfur and other pesticides, and the drug effect on humans and animals remains The harm is small, and the pests can be killed at the egg stage, so that the drug effect is strong and the efficiency is high; the active ingredients in the composition are the compound with the structural formula (1) and the plant extract, tha...

Embodiment 2

[0087]A composition, the following items in the composition can be present in the solution in the following weight percentages based on the total amount of the composition:

[0088] (a) 5% by weight of a compound of formula (1),

[0089] (b) 1wt% plant extract,

[0090] (c) 35 wt% surfactant,

[0091] (d) 44 wt% organic solvent, and

[0092] (e) 15 wt% buffer;

[0093] The composition of the present invention has a stable liquid phase structure, no stratification, no sedimentation, no organophosphorus, sulfur and other pesticides, less harm to human and animal drug residues, and can kill pests at the egg stage , so that its drug effect is stronger and its efficiency is higher; the active ingredients in the composition are compounds with structural formula (1) and plant extracts, which are compounded by the two, and the synergy between the two can greatly reduce the pest shell The hydrophilicity of the layer makes it denature and die due to dehydration and high temperature....

Embodiment 3

[0108] [1] A composition capable of reducing the hydrophilicity of shell layers of pests at the egg stage, wherein the composition comprises:

[0109] (a) compounds of the present invention having structural formula (1):

[0110] (b) plant extract of the present invention;

[0111] (c) surfactants of the present invention;

[0112] (d) organic solvents of the present invention; and

[0113] (e) Buffers of the present invention.

[0114] The composition of the present invention that can reduce the hydrophilicity of the shell layer of pests in the egg stage has a stable liquid phase structure, no stratification, no sedimentation, no organic phosphorus, sulfur and other pesticides, and the drug effect on humans and animals remains The harm is small, and the pests can be killed at the egg stage, so that the drug effect is strong and the efficiency is high; the active ingredients in the composition are the compound with the structural formula (1) and the plant extract, that is, ...

Abstract

The invention provides a composition for preventing and controlling pests and a preparation method of the composition, and belongs to the technical field of pesticide compositions. The composition comprises the following components: (a) at least one compound having a structural formula (1) shown in the description, wherein R1 and R2 are any one selected from the group consisting of a chain alkyl aldehyde, a chain alkyl acid, a cyclic alkyl aldehyde, an alkylene, an aryl aldehyde, amino and a sulfonic acid group, and the R1 and the R2 can be the same or different; (b) at least one plant extract; (c) at least one surfactant; (d) at least one organic solvent; and (e) a buffering agent. The composition provided by the invention has the following characteristics: effective ingredients containedin the composition can reduce hydrophilicity of shell layers of pests in an egg stage, and make pest eggs ''dried'' and ''starved'' until death; and no toxic insecticide substances are added into thecompositions, so that drug resistance of the pests can be remarkably reduced, and pollution to the environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticide compositions, and in particular relates to a composition for controlling pests and a preparation method thereof. Background technique [0002] Pests are humans' definition of some animals (mostly insects), which often have a negative impact on human life and production. We can often see statements like this: "There are more than 200 kinds of insects that harm corn in the world, 650 kinds of pests on elm trees, and 1,400 kinds of pests on oak trees..." List herbivorous insects that eat crops, etc. as pests , It is unscientific in terms of ecology and economics. There is an extremely complex relationship among crops, herbivores, and meat eaters. Herbivores feed on crops, and their impact on crops is different due to their varying numbers. At the same time, crops respond differently to herbivores. The flooding of some herbivorous insects is often the result of ecological imbalance, which is caus...
