Embodiment 1

[0031] The present embodiment is a kind of bactericidal auxiliary agent, and the preparation method of bactericidal auxiliary agent is as follows:

[0032] S1: Add p-xylene to a three-necked flask equipped with a magnetic stirrer, a thermometer, a condensing reflux pipe, and a chlorine gas conduit, and place the three-necked flask in a constant temperature oil bath. Under the condition of 25W ultraviolet light, feed chlorine gas into the three-necked flask to react for 35h. Go out, obtain intermediate 1; The addition of control dimethylbenzene is 1mol, and the chlorine gas flow rate is 6.0L / h;

[0033] S2: Add carbon tetrachloride to a three-necked flask equipped with a magnetic stirrer and a thermometer, then mix intermediate 1 and terephthalic acid and add it to carbon tetrachloride, under the condition of stirring at 400r / min Stir until it is completely dissolved, then add the catalyst, and continue to stir the reaction for 4 hours at a temperature of 110°C. After the reac...

Embodiment 2

[0037] The present embodiment is a kind of bactericidal auxiliary agent, and the preparation method of bactericidal auxiliary agent is as follows:

[0038] S1: Add p-xylene to a three-necked flask equipped with a magnetic stirrer, a thermometer, a condensing reflux pipe, and a chlorine gas conduit. Under the condition of 25W ultraviolet light, chlorine gas was passed into the three-necked flask to react for 37h while the 25W ultraviolet light was shining. Go out, obtain intermediate 1; The addition of control xylene is 1mol, and the flow rate of chlorine is 6.5L / h;

[0039] S2: Add carbon tetrachloride to a three-necked flask equipped with a magnetic stirrer and a thermometer, then mix intermediate 1 and terephthalic acid and add it to carbon tetrachloride, under the condition of stirring at 500r / min Stir until it is completely dissolved, then add the catalyst, and continue to stir the reaction for 4.5 hours at a temperature of 120°C. After the reaction is completed, the reac...

Embodiment 3

[0043] The present embodiment is a kind of bactericidal auxiliary agent, and the preparation method of bactericidal auxiliary agent is as follows:

[0044] S1: Add p-xylene to a three-necked flask equipped with a magnetic stirrer, a thermometer, a condensing reflux pipe, and a chlorine gas conduit. Under the condition of 25W ultraviolet light, chlorine gas was passed into the three-necked flask to react for 40h. Go out thing, obtain intermediate 1; The addition of control xylene is 1mol, and chlorine gas flow rate is 7.0L / h;

[0045] S2: Add carbon tetrachloride to a three-necked flask equipped with a magnetic stirrer and a thermometer, then mix intermediate 1 and terephthalic acid and add it to carbon tetrachloride, under the condition of stirring at 600r / min Stir until it is completely dissolved, then add the catalyst, and continue to stir the reaction for 5 hours at a temperature of 130°C. After the reaction is completed, the reaction product is subjected to rotary evapora...

Abstract

The invention discloses a bactericidal composition containing isotianil and Xinjunan acetate, and relates to the field of pesticides. The active ingredients of the bactericidal composition are isotianil, Xinjunan acetate and a bactericidal assistant, the bactericidal assistant inhibits respiration of pathogenic bacteria by inhibiting succinate dehydrogenase of composite II iron on a bacterial respiration transmission chain through an amide group, so that the sterilization effect is achieved; fluorine atoms are small in size and can be taken into the body as hydride by organisms, so the action of the amide group can be further promoted; due to the fact that introduced fluorine-containing groups have the characteristics of super acid, normal electron transfer of harmful substances is destroyed, and the sterilization effect is achieved; and fluorocarbon bonds are large in bond energy, high in stability and not prone to decomposition in the acting process in organisms, so the long-acting sterilization effect can be achieved, and the bactericidal composition has the excellent sterilization effect under reasonable compatibility of the fluorine-containing groups, the rice morbidity is reduced, the rice growth is facilitated, and the rice yield is improved.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a bactericidal composition containing Isotianil and Cycloxanil acetate. Background technique [0002] In the actual process of agricultural production, the application of chemical agents is the most effective means of preventing and controlling plant diseases and insect pests, but the most likely problem caused by chemical control of diseases is the emergence of disease resistance. In the chemical control of plant bacterial diseases, domestic and foreign researches have been carried out. After years of research, although some antibacterial agents have begun to enter the practical stage, chemically synthesized agents have disadvantages such as long cycle, high cost, high toxicity, and serious environmental pollution, which are far from meeting the requirements of sustainable agricultural development; [0003] And long-term continuous high-dose application of a single pesticide preparatio...
