Embodiment 1
[0006] Embodiment 1: the present invention is made by weight: 800 parts of plant acid, 125 parts of copper carbonate, 80 parts of zinc carbonate and 80 parts of sodium ethylenediamine tetraacetate. Under temperature, slowly add copper carbonate, react for 2.5 hours, completely dissolved, then add zinc carbonate, 2.5 hours, completely dissolve, add sodium ethylenediamine tetraacetate, stir for 3 hours, that is, the finished product with a pH value of 3.4 and a specific gravity of 1.08.
Embodiment 2
[0007] Embodiment 2: the present invention is made by plant acid 800kg, copper carbonate 125kg, zinc carbonate 80kg and sodium edetate 80kg, first plant acid is poured in the container, at 24 ℃ of temperature, slowly add copper carbonate, reaction After 1.5 hours, it was completely dissolved, then zinc carbonate was added, after 1.5 hours, it was completely dissolved, then sodium edetate was added, and stirred for 2.5 hours to obtain a finished product with a pH value of 4.2 and a specific gravity of 1.12.
Embodiment 3
[0008] Embodiment 3: the present invention is made by weight percent: plant acid 73.7%, copper carbonate 11.5%, zinc carbonate 7.4% and sodium ethylenediamine tetraacetate 7.4%, earlier plant acid is poured in the container, at 29 At ℃ temperature, slowly add copper carbonate, react for 1 hour, completely dissolve, then add zinc carbonate, 1 hour, completely dissolve, add sodium ethylenediaminetetraacetate, stir for 2 hours, it is a finished product with a pH value of 5.1 and a specific gravity of 1.17.
[0009] The present invention has different bacteriostasis effects on different pathogenic bacteria. After testing, for 3 consecutive years, the average: 100 apples can suppress 66% of spotted leaf spot, 1 mu of cucumber can suppress 83.3% of botrytis cinerea, and 150 apples can suppress brown spot disease. 39.8%, 1.5 mu of cucumber blight suppressed 43.3%, cotton 2 mu blight suppressed 37.5%, rice blast 5 mu suppressed 31.6%, yam 0.5 mu anthracnose suppressed 22.6%, apple rot ...

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...
