Problems solved by technology

[0005] The cell membrane is a semipermeable barrier between the cell and the extracellular environment. It has selective permeability and effectively ensures the relative stability of the intracellular environment. Although this phospholipid bilayer is essential for the survival and function of cells, it is It creates obstacles to the exchange of cargo molecules inside and outside the cell. Since it is difficult for drug macromolecules to enter the cell and reach a sufficient concentration, the cell membrane of drug-resistant pests and diseases will prevent the entry of active ingredients of pesticides, resulting in poor drug efficacy and cell penetration Peptides can solve this problem

Embodiment 1

[0019] 1. Sample matching.

[0020] ① 15% dinotefuran EC.

[0021] Element

[0022] ② 15% dinotefuran EC (adding cell penetrating peptide).

[0023]

[0024]

[0025] 2. Drug efficacy verification.

[0026] A total of 2 chemical treatments were set up, and after dilution, the drug efficacy was verified on rice planthoppers with severe drug resistance. The test results and records are as follows:

[0027] Pharmacy treatment

[0028] 3. Conclusion: At the same concentration, the effect of adding cell-penetrating peptides to 15% dinotefuran EC is better than that without adding cell-penetrating peptides.

Embodiment 2

[0030] 1. Sample matching.

[0031] ① 1.9% abamectin emulsion in water.

[0032] Element

[0033] ② 1.9% abamectin water emulsion (adding cell penetrating peptide).

[0034] Element

[0035] 2. Drug efficacy verification: A total of 2 drug treatments were set up, and after dilution, drug efficacy verification was performed on the highly resistant spider mite. The test results and records are as follows:

[0036] Pharmacy treatment

[0037] 3. Conclusion: at the same concentration, the effect of adding cell penetrating peptide to 1.9% abamectin aqueous emulsion is better than that without adding cell penetrating peptide.

Embodiment 3

[0039] 1. Sample matching.

[0040] ① 1.9% emamectin microemulsion.

[0041] Element

[0042] ② 1.9% emamectin microemulsion (adding cell penetrating peptide).

[0043] Element

[0044] 2. Drug efficacy verification: A total of 2 drug treatments were set up, and after dilution, drug efficacy verification was performed on diamondback moths with severe drug resistance. The test results and records are as follows:

[0045] Pharmacy treatment

[0046] 3. Conclusion: At the same concentration, the drug effect of adding cell penetrating peptide to 1.9% emamectin microemulsion is better than that without adding cell penetrating peptide.

Abstract

The invention relates to a pesticide preparation for reducing drug resistance of plant diseases and insect pests and application thereof. The pesticide preparation provided by the invention comprisesthe following components by weight percent: 0.1%-70% of pesticide active ingredients, 0.5%-5% of cell penetrating peptide, 1%-20% of a surfactant, and a solvent supplementing to 100%. According to thepesticide preparation provided by the invention, the cell penetrating peptide is added to enable the pesticide active ingredients to penetrate cell membranes, thereby greatly improving a rate of penetrating the cell membranes of insects of the pesticide, and improving the fast-acting property and efficacy of the pesticide.

Description

technical field [0001] The invention relates to a pesticide preparation for reducing the drug resistance of diseases and insect pests and an application thereof, belonging to the field of agricultural chemistry. Background technique [0002] Pest resistance has a history of hundreds of years since 1908, when the resistance to lime sulfur was first discovered in the American pear round ant. By 1948, 14 kinds of insect pests had become resistant to insecticides, by 1964 they had increased to 224, by 1976 they had increased to 364, and by 1984 they had increased to 447. Up to now, at least 600 kinds of insects and mites have developed resistance to insecticides. Among these pests, Diptera and Lepidoptera insects have the largest number of resistant species. There are 45 species of insects resistant to pesticides in my country, including 36 species of agricultural pests and 9 species of sanitary pests. The pests with outstanding resistance include cotton aphid, cotton bollworm...
