Embodiment 1

[0017] 1. Target preparation: 3% emamectin benzoate and 7% indoxacarb suspension concentrate.

[0018] 2. Preparation method: prepared by conventional methods in the industry, the effective dose of synergistic components is preferably 1%.

[0019] 3. Stability observation experiment.

[0020] 3% emamectin benzoate 7% indoxacarb suspension was prepared according to the above-mentioned experimental operation steps, and the conditions were cold storage (0±1°C) for 7 days, heat storage (54±2°C) for 14 days, and normal temperature ultraviolet light irradiation for 24h. The decomposition rates of emamectin benzoate / indoxacarb were 0.09% / 0.23%, 0.33% / 0.48%, and 1.19% / 2.01%, respectively.

Embodiment 2

[0022] 1. Target preparation: 2.5% cypermethrin 22.5% chlorpyrifos EC.

[0023] 2. Preparation method: prepared by conventional methods in the industry, the solvent is turpentine oil, and the effective dose of synergistic components is preferably 2.5%.

[0024] 3. Stability observation experiment.

[0025] 2.5% cypermethrin 22.5% chlorpyrifos emulsifiable concentrate was prepared according to the above-mentioned experimental operation steps, and under the conditions of cold storage (0 ± 1 ℃) for 7 days, hot storage (54 ± 2 ℃) for 14 days, and normal temperature ultraviolet light irradiation for 1 day, cypermethrin / The decomposition rates of chlorpyrifos were 0.30% / 0.22%, 0.68% / 0.89%, 1.17% / 1.53%, respectively.

Embodiment 3

[0027] 1. Target preparation: 4.5% beta-cypermethrin emulsifiable concentrate.

[0028] 2. Preparation method: prepared by conventional methods in the industry, the solvent is 12% ethyl acetate, and the effective dose of synergistic components is preferably 1.5%.

[0029] 3. Stability observation experiment.

[0030] The 4.5% beta-cypermethrin emulsifiable concentrate was prepared according to the above-mentioned experimental operation steps, and the decomposition rate of beta-cypermethrin was obtained under the conditions of cold storage (0±1°C) for 7 days, heat storage (54±2°C) for 14 days, and normal temperature ultraviolet light irradiation for 24 hours. They are 0.12%, 0.36%, and 1.38%, respectively.

Abstract

The invention relates to a synergistic insecticide containing pteroylglutamic acid, the main active ingredient of the synergistic insecticide is selected from indoxacarb, cypermethrin, chlorpyrifos, efficient cypermethrin, efficient cyfluthrin, and bifenthrin , monosultap, abamectin, emamectin benzoate, imidacloprid, acetamiprid, chlorfenapyr or a combination of two. The pteroyl glutamic acid is mixed with the insecticide by a conventional method to prepare a conventional dosage form, and the effective content of the pteroyl glutamic acid in the preparation is 1-5%. The insecticide prepared by applying the method has remarkable effect and is environment-friendly, and is a new type of environment-friendly insecticide.

Description

technical field [0001] The invention relates to the field of pesticides and insecticides, in particular to a synergistic insecticide containing pteroylglutamic acid and its application technology. Background technique [0002] Pesticides play a very important role in agricultural production. Organic chemical pesticides have greatly enhanced the ability of humans to control pests and diseases, and have made a significant contribution to our restoration of crop yield losses. However, the long-term dependence and extensive use of organic synthetic chemical pesticides have brought about a series of well-known problems such as environmental pollution, ecological balance damage and food safety, and have brought many adverse effects on promoting the sustainable development of the agricultural economy. [0003] With the improvement of people's health awareness, reducing pesticide residues and developing new pesticides has become a top priority. The use of green solvents to replace d...
