Composite plant acid copper zincium bactericidal agent

Abstract

The invention relates to a composite plant acid copper and zinc bactericide which can effectively solve the problems of high toxicity, impact on the quality of agricultural products and serious threat to human health of the existing biological bactericidal products, the technical proposal for the solution is as follows, the composite plant acid copper and zinc bactericide is counted by the weight percentage: 47 to 83 percent of plant acid, 5 to 28 percent of copper carbonate, 5 to 19 percent of zinc carbonate and 4 to 19 percent of sodium ethylene diamine tetraacetate, the total amount is 100 percent, the plant acid is firstly poured into a container, the copper carbonate is slowly added for carrying out the reaction for 1 to 3 hours at the temperature of 18 to 30 DEG C, the zinc carbonate is further added after the complete dissolution for carrying out the reaction for 1 to 3 hours, the sodium ethylene diamine tetraacetate is added to be stirred for 2 to 3 hours after the complete dissolution, the even mixing is carried out, and then the bactericide finished product with the pH value of 3 to 5.5 and the specific weight of 1.0 to 1.2 is prepared. The bactericide has scientific and reasonable formula, easy production, no pollution and no toxicity or side effects, the bactericide can effectively inhibit the diseases of crops caused by fungi, the application is wide and the bactericide is another creation in agricultural biological bactericides.

Description

1. Technical field [0001] The invention relates to the field of pesticides, in particular to a copper-zinc compound phytate fungicide. 2. Background technology [0002] The high yield of crops is inseparable from the fertilization of crops and the prevention and control of pests and diseases. Pesticides are used to prevent and control pests and diseases. 1. A large amount of highly toxic pesticides are used, causing the pesticide residues in agricultural products to exceed the standard. Most of the pesticides remain on the surface of vegetables and fruits, or penetrate into the soil, water and air. If people use vegetables and fruits with pesticide residues for a long time Such agricultural products not only inhibit the growth of crops, but are also extremely harmful to the human body. In recent years, food poisoning incidents caused by pesticide residues on vegetables, melons and fruits and other agricultural products have occurred frequently. Standards have hindered the expo...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the object of the present invention is to provide a copper-zinc compound phytate fungicide, which can effectively solve the problems of existing biological sterilization products, which have high toxicity, affect the quality of agricultural products, and seriously threaten human health. Problem, the technical solution that it solves is, the present invention is in percentage by weight: plant acid 47-83%, copper carbonate 5-28%, zinc carbonate 5-19% and sodium edetate 4-19%, The total amount is 100%. Pour the plant acid into the container first, and slowly add copper carbonate at a temperature of 18-30°C, react for 1-3 hours, and dissolve completely, then add zinc carbonate, 1-3 hours, completely Dissolve, then add sodium ethylenediamine tetraacetate and stir for 2-3 hours, and mix well, which is a finished fungicide with a pH value of 3-5.5 and a specific gravity of 1.0-1.2. The plant acid is expressed in weight percent: acetic acid 48 %, propionic acid 43%, acetone 1.7%, 2-furan aldehyde 2.1%, 2-cyclopentenone 0.2%, guaiacol 0.3%, p-cresol 1.0%, to-cresol 1.4%, o-cresol 1.2 %, composed of ethyl guaiacol 0.3%, furfural 0.5% and flavonoids 0.7%
