Problems solved by technology

Pesticides mostly treat one insect for one treatment, and one drug for one treatment. Therefore, pesticides can only control one pest or disease, and have no effect on other poisons or diseases, and even cause production reduction accidents. No harvest
This kind of plant protection technology of treating one insect, one medicine and one medicine is no longer suitable for the needs of agricultural development. Farmers urgently need one medicine to treat multiple diseases, treat both diseases and insects, save medicine and labor, maintain production and increase production, easy to use, and have significant benefits. new technology for pesticide application

[0061] Example one tetramycin and dimethomorph complex

[0062] Wherein, dimethomorph is selected as the active material component. The original drugs of tetramycin and dimethomorph were made into 20% suspension concentrate respectively, and the indoor pot experiment was carried out. The test method was carried out with reference to Wu Wenjun's "Introduction to Experimental Techniques of Plant Chemical Protection" (1993). According to the requirements of the experiment, single doses and types with corresponding mass ratios were made respectively. The specific data of the test results are shown in Table 1.

[0070] Example tetramycin compounded with chlorothalonil

[0071] Among them, chlorothalonil is selected as the active material component, and its chemical name: tetrachloroisophthalonitrile (2,4,5,6-tetrachloro-1,3-benzenedicyanonitrile), is a broad-spectrum, protective bactericidal agent. The mechanism of action is that it can interact with glyceraldehyde triphosphate dehydrogenase in fungal cells, and combine with the protein containing cysteine ​​in the enzyme, thereby destroying the activity of the enzyme, destroying the metabolism of fungal cells and losing vitality . Chlorothalonil has no systemic conduction effect, but after being sprayed on the plant body, it can have good adhesion on the body surface and is not easily washed away by rain, so the drug effect period is longer.

[0072] It is used to control various fungal diseases of fruit trees, vegetables, and cereal crops, especially for the control of wheat powdery mildew.

[0075] Toxicity determination of tetramycin mixed with chlorothalonil against wheat powdery mildew

[0076] 1) Drug preparation

[0077] Tetramycin solution: Accurately weigh the tetramycin mother solution and dilute it to a concentration of 25, 12.5, 6.25, 3.125, 1.5625mg / L for later use.

[0078] Chlorothalonil solution: Accurately weigh 0.01g of the original drug with a weight concentration of 97% chlorothalonil, dissolve it with 0.2ml dimethylformamide, add 97ml of clear water containing 0.1% Tween 80 surfactant, stir evenly, and prepare chlorothalonil Bacteria clear 100mg / L mother solution, then diluted with clear water containing 0.1% Tween 80 surfactant to 50, 25, 12.5, 6.25, 3.125mg / L concentration for subsequent use.

[0079] Each mixed solution: take 5, 3, 3, 3, 2ml 100mg / L tetramycin solution respectively, add 5, 9, 15, 21, 18ml 100mg / L chlorothalonil solution to make 50mg / L tetramycin Element: chlorothalonil 1:1, 1:3, 1:5, 1:7, 1:9 solution, then diluted with wat...

Abstract

The invention relates to the field of biopesticide preparation research and development, and particularly relates to a tetramycin compound and application, which is the divisional application, wherein the application number is 2013106143470, the application date is Nov, 26th, 2013, and the invention title is tetramycin compound and application. The tetramycin compound comprises tetramycin and active substances, wherein the active substances are pyrroles or copper compounds. Compared with the prior art, according to the tetramycin compound and application which are provided by the invention, the danger of selectivity of resistant fungi strains is reduced; the service lives of the active components are shortened; the prevention and treatment range is expanded; the disease prevention effect is improved; the drug resistance of germs can be slowed down or overcome; the cost is reduced, and the application times of the pesticide is reduced.

Description

[0001] The application of the present invention is a divisional application with the application number 2013106143470, the application date is November 26, 2013, and the invention name is "tetramycin compound and its application". technical field [0002] The invention relates to the field of research and development of biopesticide preparations, in particular to tetramycin complexes and their application. Background technique [0003] At present, there are many kinds of pesticides used for plant protection. It is a good thing that there are many kinds of pesticides, but it also brings many problems. Pesticides mostly treat one insect for one treatment, and one drug for one treatment. Therefore, pesticides can only control one pest or disease, and have no effect on other poisons or diseases, and even cause production reduction accidents. No grain harvest. This kind of plant protection technology of treating one insect, one medicine and one medicine is no longer suitable for...
