Problems solved by technology

[0004] When herbicides, insecticides or fungicides are used, due to the poor spread of pesticides or the thick cuticle of the leaves, the leaves cannot adhere to or absorb the pesticides, so they cannot conduct systemic conduction, resulting in the inability to exert their efficacy
At the same time, under the condition of low temperature, its drug effect is slower
In addition, pesticides are lethal after drifting, which is irreparable harm to crops

preparation example Construction

[0033] Another aspect of the present invention also provides a preparation method of the above-mentioned herbicidal composition, comprising the following steps:

[0034] Step 1: Stir and mix the herbicide and deionized water to obtain the herbicide mother liquor;

[0035] Step 2: Prepare citrus essential oil mother liquor, dissolve citrus essential oil with alcohol solvent, then add nonionic surfactant and stir evenly;

[0036] Step 3: Inject the herbicide mother liquor into the citrus essential oil mother liquor, and then inject deionized water for stirring for 1 to 1.5 hours, and mix evenly to obtain a herbicidal composition.

[0037] Taking glyphosate isopropionate as an example, the steps for preparing the herbicidal composition are as follows:

[0038] Step 1: Prepare glyphosate isopropionate mother liquor, stir and mix glyphosate technical, isopropylamine and deionized water;

[0039] Step 2: Prepare citrus essential oil mother liquor, dissolve citrus essential oil wit...

Embodiment 1

[0073] (1) Measure 48.4g of 95% glyphosate technical material, 20.4g of 99% isopropylamine and 31.2g of deionized water and stir for 3h, and prepare 100g of 62% glyphosate isopropionate mother liquor. Add slowly to control the temperature below 60 degrees.

[0074] (2) 31 g of citrus essential oil, 26 g of ethanol, and 43 g of fatty alcohol polyoxyethylene ether were mixed and stirred for 1 hour to prepare 100 g of 31% citrus essential oil mother liquor.

[0075] (3) In parts by weight, four parts of 62% glyphosate isopropionate mother liquor is injected into a part of 31% essential oil mother liquor and stirred for one hour to obtain a mixed liquor, at which time the solution will be stratified, and then injected The total mass of the mixture was 16% deionized water, and after stirring for 1 hour, a uniformly mixed herbicidal composition was obtained.

Embodiment 2

[0077] (1) Measure 32g of 95% glyphosate technical material, 13.5g of 99% isopropylamine and 54.5g of deionized water and stir for 3 hours to prepare 100g of 41% glyphosate isopropionate mother liquor. Slowly add isopropylamine Add control temperature below 60 degrees.

[0078] (2) 31 g of citrus essential oil, 26 g of ethanol, and 43 g of fatty alcohol polyoxyethylene ether were mixed and stirred for 1 hour to prepare 100 g of 31% citrus essential oil mother liquor.

[0079] (3) Get four parts of 62% glyphosate isopropionate mother liquor and inject a part of 31% essential oil mother liquor and stir for one hour to obtain a mixed solution, at this moment, the solution will be stratified, and then inject 16% of the total mass of the mixed solution % deionized water, after stirring for 1 hour, a uniformly mixed herbicidal composition was obtained.

Abstract

The invention provides a pesticide synergist and thereof in a herbicidal composition, a insecticidal composition and a bactericidal composition. The pesticide synergist is citrus essential oil. The citrus essential oil contains grapefruit essential oil and orange peel essential oil. A pesticide composition is any one or more of the herbicidal composition, insecticidal composition and bactericidalcomposition. The pesticide composition of the invention is enhanced in spreadability on a leaf, overcomes pesticide liquid slip loss caused by hydrophobicity of a waxy layer of the leaf, reduces driftof pesticide liquid, and can carry the pesticide to rapidly penetrate a stratum corneum of the leaf so as to make full use of the effect of the pesticide. The citrus essential oil of the invention contains the orange peel essential oil and grapefruit essential oil at an appropriate proportion and has good pesticide liquid penetration effect. In a preparation method of the pesticide composition provided by the invention, the citrus essential oil and the pesticide components are separately formulated into mother liquid and then mixed, which facilitates the uniform dispersion of the components in the system and helps to improve the effect of the pesticide.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a pesticide synergist and its application in herbicidal compositions, insecticidal compositions and fungicidal compositions. Background technique [0002] Pesticides are widely used in agricultural, forestry and animal husbandry production, environmental and household sanitation, pest control and epidemic prevention, and industrial product mildew and moth prevention. There are many varieties of pesticides, which can be mainly divided into insecticides, acaricides, rodenticides, nematocides, molluscicides, fungicidal compositions, herbicidal compositions, plant growth regulators, etc. according to their uses. [0003] Some of the pesticides applied to crops are attached to the crops, some are scattered in the soil, air and water environment, and some of the pesticides remaining in the environment will be absorbed by plants. Pesticide residues reach humans and animals directly through pl...
