Abstract
A kind of inorganic copper spectrum bactericide dijuntong, it is that the copper oxychloride of 70-85% by weight percentage, the copper sulphate of 10-15% and the copper citrate of 5-15% are formed.Wherein copper oxychloride is to be the hydrogen peroxide of 75% copper chloride and 25% or the product of air reaction by percentage by weight.The dijuntong product is pulvis or tablet, and storing, preparation are conveniently renderd a service lastingly.Can mix use with any insecticide, bactericide, to the obvious influence of not having of mite class.Nonpoisonous, non-environmental-pollution, safety is good.
Description
The present invention relates to agricultural chemicals and preparation method thereof, is a kind of inorganic copper wide-spectrum bactericide and preparation method thereof specifically.
Traditional inorganic copper series bactericidal agent-bordeaux mixture sterilizing power is strong, the drug effect scope is wide, and effect is lasting.It is usually used in the control of each planting fruit-trees and economic crops disease.It is formulated by copper sulphate, lime and water.The weak point that bordeaux mixture exists is:
(1) it must be now with the current, can not store, and causes to use inconvenience;
(2) can not mix use with other bactericide, insecticide;
(3) easily cause the mite class to take place after the use.
The objective of the invention is to, overcome the shortcoming of existing inorganic copper series bactericidal agent, create a kind of can the storage, can mix use with other bactericide, insecticide, and generation does not have Powdered inorganic copper wide-spectrum bactericide of obviously influence and preparation method thereof to the mite class.
The objective of the invention is to reach by following measure:
A kind of inorganic copper wide-spectrum bactericide dijuntong is characterized in that it is by copper oxychloride ClCuO-OCuCl, copper sulphate CuSO
4And copper citrate
Form.
The preparation method of inorganic copper wide-spectrum bactericide-dijuntong is characterized in that, each weight percentages of components of dijuntong is:
Copper oxychloride 70-85%,
Copper sulphate 10-15%;
Copper citrate 5-15%
The step and the process conditions thereof of preparation are as follows:
(1) preparation of copper oxychloride
Percentage by weight is 75% copper chloride and 25% hydrogen peroxide or air reaction, generate copper oxychloride, its reaction condition is under stirring, temperature control is in 50-80 ℃ of scope, carry out oxidation reaction, after reaction finishes, detect with the atom spectrophotometric method, when the mol ratio of Cu: Cl: O is 1: 1: 1, is shown reaction and finishes.Reactor product is dry under 85 ℃ of conditions, and it is standby to make pulvis;
(2) preparation of dijuntong
Percentage by weight by each component among the above-mentioned preparation method feeds intake, fully fiat pulvis misce or tablet.
The main component of the dijuntong that the present invention is prepared and long-acting composition are copper oxychlorides.Do not have ready-made copper oxychloride to sell on the market, the inventor prepares the pulvis copper oxychloride.Copper oxychloride is a basic copper, and film forming characteristics is good, after spray is distributed in crop surface, can form the water-soluble very low film of one deck.When it touches the plant secretion thing, carbon dioxide in air and oozy organic acid when running into germ spore alliance and sending out, the copper ion that dissociates gradually, copper ion enters in the germ body, makes that protoplasm solidifies sex change in the cell, and germ is promptly dead, plays prophylaxis effect.Copper citrate is a kind of complex copper, and after copper was free, citrate had good buffer capacity, and it has increased the stability of system.Copper sulphate is a kind of water soluble salt, and it is the main component in traditional bacteriocide formula, and it is converted water and sprays when crop surface, and copper ion discharges at once, and acts on germ, the present invention still it as quick-acting compositions.
Be embodiments of the invention below
Embodiment 1
1, the preparation of copper oxychloride
According to chemical equation:
Get percentage by weight and be 75% stannous chloride CuCl, be dissolved in the water that is equivalent to about 3 times of stannous chloride weight and 25% oxydol H
2O
2Put into the reactor that has agitator together, be warming up to 60 ℃, reaction generates moisture copper oxychloride while stirring, and is dry under 85 ℃ of temperature then, pulverizes the powder system of making.
2, the preparation of dijuntong
With copper oxychloride weight is benchmark, is 80% by its percentage by weight, the copper sulphate percentage by weight be 10% and the copper citrate percentage by weight be that 10% rate of charge feeds intake, after fully mixing, compressing tablet, packing are the product that dispatches from the factory.
Embodiment 2
1, the preparation of copper oxychloride
Get in the water that 100 kilograms of stannous chlorides are dissolved in 300 kilograms, put into the reactor that has agitator after, feed enough air, and be warming up to 80 °, under stirring condition, react, generate the copper oxychloride aqueous solution, dry under 85 ℃ of temperature then, be ground into pulvis.
2, the preparation of dijuntong
With the copper oxychloride weight that makes is benchmark, and by its percentage by weight 85%, adds copper sulphate and copper citrate percentage by weight and respectively is 7.5% rate of charge and feed intake, and makes pulvis after fully mixing.
The present invention compares with background technology has following advantage:
1, storing is convenient, and it is lasting to render a service
The inventor once did the Comparision Test of dijuntong liquid and Bordeaux mixture, result such as following table:
During the result of the test table, Bordeaux mixture preparation is after 30-48 hour, will form the slightly solubility crystalline deposit and loses efficacy. How long no matter dijuntong liquid placed, and all can not lose efficacy, moreover the dijuntong product is pulvis or tablet, water-soluble during use, is mixed with optimum concentration, convenient, reliable.
2, can with any neutrality and acid pesticide, bactericide mixes just to be used. Under alkali condition, also do not lose efficacy, but suspension is relatively poor, and more easily precipitates, therefore mix with alkaline agricultural chemicals then should now join when using and use.
3, use dijuntong to the having no significant effect of mite class, and promote the mite class to occur in a large number after using Bordeaux mixture. The comparison of the following table impact that to be dijuntong and Bordeaux mixture occur the mite class:
4, also additive capable of using as feed of this product, so Nonpoisonous, non-environmental-pollution is to the person poultry safety.
