Abstract
This fungicide is prepd. by mixing 10-80% copper resinate or copper dehydroabietate, 10-80% bulking material and 5-30% dispersant to form wettable fungicide powder or is prepd. by mixing 10-50% copper resinate or copper dehydroabietate 30-70% organic solvent and 5-40% surface active agent to form emulsoid fungicide. This prepd. broad-spectrum fungicide organic copper can be used together with other insecticide, acaricide to produce synergistic effect.
Description
The present invention relates to a kind of preparation method of broad-spectrum germicide, especially a kind of broad-spectrum germicide organic copper preparation method.
Used wide-spectrum bactericide is generally inorganic copper fungicide in the prior art at present, as traditional inorganic copper fungicide-bordeaux mixture, it is usually used in the disease of preventing and treating of multiple fruit tree and economic crops, it is to be formed by copper sulphate, lime and water configuration, its weak point is: (1) accumulating for a long time, and must be now with the current; (2) can not use with other insecticidal bactericides; (3) easily cause the mite class to be broken out after the use; (4) easily on many fruit trees and economic crops poisoning appears.And for example the patent No. is the patent of 93115324.7 " inorganic copper wide-spectrum bactericide-dijuntong and preparation method thereof ", though it has solved " accumulating for a long time; must be now with the current, can not use with other insecticidal bactericides " etc. problem, but still be difficult to resolve the problem of " easily on many fruit trees and economic crops, poisoning occurring ".
The object of the present invention is to provide a kind of can accumulating, can mix use with other Insecticidal and acaricidal agents, and can weaken the harm of mite class, fruit tree and economic crops are had the broad-spectrum germicide organic copper preparation method of safe and efficient effect.
Purpose of the present invention can be achieved through the following technical solutions: a kind of preparation method of wide-spectrum bactericide organic copper is that mixture, 10～80% fillers and 5～30% dispersant with 10～80% copper resinates or dehydro copper abietate or copper resinate and dehydro copper abietate are prepared into wetting powder shape bactericide.
Purpose of the present invention also can be achieved through the following technical solutions: a kind of preparation method of wide-spectrum bactericide organic copper is that mixture, 30～70% organic solvents and 5～40% surfactants with 10～50% copper resinates or dehydro copper abietate or copper resinate and dehydro copper abietate are mixed with into the creamy bactericide.
In above-mentioned two kinds of technical solutions, the preparation method of described copper resinate or dehydro copper abietate is:
(1). the aqueous solution reaction of the water-soluble back of disproportionated rosin potassium soap or other rosin salts and inorganic mantoquita or organic copper salt, wherein the percentage by weight of each component of reactant is: disproportionated rosin potassium soap or other rosin salt aqueous solution are 75～95%, inorganic mantoquita or the organic copper salt aqueous solution are 5～25%.
(2). get former powder behind reactant press filtration and the heat drying.
Purpose of the present invention can be achieved through the following technical solutions again: a kind of preparation method of wide-spectrum bactericide organic copper is to add the surfactant that accounts for its composition 5～40% in the solution of copper resinate or dehydro copper abietate, to be prepared into the creamy bactericide.
In above-mentioned technical solution, the preparation method of described copper resinate or dehydro copper abietate solution is: with disproportionated rosin potassium soap or other rosin salts and organic solvent, water and inorganic mantoquita or organic copper salt stirring reaction under (20～80 ℃) condition, promptly generate the solution of copper resinate or dehydro copper abietate, wherein the percentage by weight of disproportionated rosin potassium soap or other rosin salts, organic solvent, inorganic mantoquita or organic copper salt is 18～60%: 35～70%: 4～12%.
In aforesaid technical solution, described organic solvent is diesel oil or machine oil or dimethylbenzene or benzene or acetone or ether or cyclohexanone or turpentine oil or turpentine or Tianna solution or dipentadiene or said mixture.
In aforesaid technical solution, described dispersant is the ionic surface active agent of anion surfactant or cationic surfactant or zwitterionic surfactant or non-ionic surface active agent or above-mentioned mixed type.
The broad-spectrum germicide organic copper can be well dispersed in the water, forms suspension.The suspension of being joined is sprayed onto the surface of plant, and a part of porous most ofly forms the film of one deck copper-containing compound at plant surface in plant corpus, thereby plays the effect of sterilizing disease-preventing.It is neutral that the wide-spectrum bactericide organic copper is, and has extremely strong adhesivity and dispersiveness, can use with other Insecticidal and acaricidal agents, has certain synergistic effect.
Below by specific embodiment the present invention is made further explanation and description:
Embodiment one: 100 gram copper sulphate, 450 gram disproportionated rosins acid potassium, 1000 milliliters of turpentine oil, 1000 ml waters are mixed stirred 1～2 hour, left standstill 2 hours, supernatant is the organic solution of a hydrogen abietic acid copper.Add surfactant in the separating obtained organic solution, its ratio is: 500～800 parts of organic solutions, 150 parts in surfactant fully stirs, and promptly gets the wide-spectrum bactericide organic copper.
Embodiment two: respectively 150 gram copper sulphate are dissolved in the long water of 1000 millis, 800 gram potash soaps are dissolved in 1600 ml waters.After both are mixed, heat 50 ℃, stir 2 hours with product drying under 50 ℃ temperature, get former powder.Get former powder 500 grams and be dissolved in 1000 milliliters of turpentine oil, add 150 milliliters of surfactants again, stir, leave standstill, gained supernatant ripple is this product.
This kind wide-spectrum bactericide organic copper is applied on the citrus, the efficient of preventing and treating of anthracnose is reached 95%, canker is prevented and treated efficient and is reached 91%, and the mite class is had repellent action.Use with miticides such as the spirit of despot mite, " Shamanliguo " miticide for fruit tree, kill mite efficient and improve 10～20%.The efficient of preventing and treating to watermelon anthrax reaches 98%.
