Problems solved by technology

Yet along with the widespread use of pesticides, environmental problems are becoming more and more serious. The chemical components contained in the pesticides have changed the soil structure and polluted the water source. The application number is that CN94101332.4 discloses a pesticide and its production process. Insecticide, characterized in that it contains 2-dimethylamino-1,3-dithiosulfonate ammonium propane, prepared by reacting 3-dimethylamino-1,2-dichloropropane and ammonium thiosulfate obtained, and its feeding ratio is 1:2.03-2.05, heated to 73-76°C under stirring, kept warm for 2-4 hours, then continued to heat up to 80-85°C, kept warm for 0.5-1.5 hours, cooled and adjusted the pH to slightly It is acidic and collects the reaction products. This insecticide has a significant effect on pest control, low dosage, does not affect the soil properties when used, and has better storage stability than similar products at present. The time is short, the drug effect is low, and it is unstable, not environmentally friendly, and the degree of environmental pollution is large, and it cannot supplement nutrients to plants.

Embodiment 1

[0021] A kind of production technique of efficient environment-friendly insecticide of the present embodiment, its processing step is as follows:

[0022] (1) Selection of raw materials; by weight percentage, respectively select 25% of avermectin, 8% of monoclonal, 20% of surfactant, 8% of genthilon, and 2% of compound fertilizer as raw materials, and make up the rest with water;

[0023] (2) Grinding and dissolving; the raw materials selected in step (1) are crushed and sieved through a 150-mesh vibrating sieve, then the raw materials are put into the reaction kettle, a cosolvent is added, and the raw materials are stirred until the raw materials are completely dissolved to obtain the dissolved original drug. Described solubilizer is the mixed solution of isophorone and cyclohexanone;

[0024] (3) Preparation of auxiliary agent: mix soft water and foaming agent according to the mass ratio of 3:2, fill with water and stir to prepare auxiliary agent;

[0025] (4) Modification:...

Embodiment 2

[0028] Example 2: The rest are the same as in Example 1, except that the ratio of isophorone and cyclohexanone in step (2) is 1:2, the temperature is controlled at 40°C in step (4), and the temperature is controlled in step (6). The temperature is 80°C.

Embodiment 3

[0029] Example 3: The rest is the same as that of Example 1, except that the controlled temperature in step (4) is 50° C., the controlled temperature in step (6) is 90° C., and the controlled cooling time is 60 minutes.

[0030] In the above-mentioned three examples, genthirone not only has all the characteristics of azone, but also the effect of the genthirone penetration enhancer on berberine is 2.99 times that of azone. In the acute toxicity test, LD50 The value cannot be measured, so it is proved that the permeation enhancer of high chrysothinone is better than that of azone; the surface active agent has a large surface tension, and it can be quickly distributed on the surface of objects in its liquid state. During the experiment, the respiratory tract of rats was blocked. It was suffocated to death, and the monitoring showed that the process took 60 to 80 minutes.

[0031] It can be seen from practical application that the production process of high-efficiency and envir...

Abstract

A disclosed production technology for an efficient environment-friendly pesticide comprises the technological steps: (1) selecting raw materials; (2) crushing and dissolving; (3) preparing an auxiliary agent; (4) modifying; (5) enhancing medicine properties; and (6) gelatinizing. The production technology is reasonable and concise in technology and long in storage time, and the pesticide is strong and stable in effect and small in environmental pollution, and is capable of providing various nutrition fertilizers for plants.

Description

[0001] technical field [0002] The manufacturing process of chemical pesticides involved in the present invention, in particular, relates to a production process of high-efficiency and environment-friendly insecticides. Background technique [0003] At present, pesticides have been widely used in the field of agricultural production. With the development of agriculture, especially the emergence of large-scale contracted farmland, the demand for pesticides is increasing day by day. Yet along with the widespread use of pesticides, environmental problems are becoming more and more serious. The chemical components contained in the pesticides have changed the soil structure and polluted the water source. The application number is that CN94101332.4 discloses a pesticide and its production process. Insecticide, characterized in that it contains 2-dimethylamino-1,3-dithiosulfonate ammonium propane, prepared by reacting 3-dimethylamino-1,2-dichloropropane and ammonium thiosulfate ...
