Abstract
The present invention discloses a preparation method of organic copper which is universal bactericide. Wettable powdery bactericide prepared by the mixing of 10 to 80% of copper resinate or dehydrogenation abietic acid copper, 10 to 80% of filling materials and 5 to 30% of a dispersing agent; or emulsifiable bactericide is prepared by the mixing of 10 to 50% the copper resinate or the dehydrogenation abietic acid copper, 30 to 70% of organic solvent and 5 to 40% of a surface active agent; or the emulsifiable bactericide is prepared by the copper resinate or the dehydrogenation abietic acid copper by adding the surface active agent which is 5 to 40% of ingredients. The organic copper of the universal bactericide of the present invention can be stored and transported for a long time, has strong adhesiveness and dispersivity, can be mixed with other kinds of bactericide and acaricide, and performs a definite synergistic effect.
Description
The present invention relates to a kind of organic copper bactericide and preparation method thereof.
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 ", and " accumulating for a long time must be now with the current though it has solved; 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 the accumulating of a kind of energy, can mix use with other insecticides, miticide, and can weaken the harm of mite class, fruit tree and economic crops are had organic copper bactericide of safe and efficient effect and preparation method thereof.
The objective of the invention is to be achieved through the following technical solutions: a kind of organic copper bactericide, it contains mixture, 10-80% filler and the 5-30% dispersant of 10-80% copper resinate or dehydro copper abietate or copper resinate and dehydro copper abietate.
Above-mentioned technical scheme realizes by the following method:
(1) react with the aqueous solution of inorganic mantoquita or organic copper salt the water-soluble back of disproportionated rosin potassium soap or other rosin salt, and wherein the percentage by weight of each component of reactant is: disproportionated rosin potassium soap or other rosin salt aqueous solution are that 75-95%, inorganic mantoquita or the organic copper salt aqueous solution are 5-25%.
(2) obtain copper resinate or the former powder of dehydro copper abietate behind product press filtration and the heat drying.
(3) above-mentioned former powder and filler, dispersant are mixed with into wetting powder shape bactericide in proportion.
Purpose of the present invention can also be achieved through the following technical solutions:
A kind of organic copper bactericide is characterized in that it contains the solution and the surfactant of copper resinate or dehydro copper abietate, and wherein the shared component of copper resinate or dehydro copper abietate is 10-50%.
Aforesaid technical scheme realizes by the following method:
(1) 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 or other rosin salts, organic solvent, inorganic mantoquita or organic copper salt is 18-60%: 35-70%: 4-12%.
(2) in above-mentioned solution, add an amount of surfactant and be prepared into the creamy bactericide.
In aforesaid technical solution, described organic solvent is diesel oil or machine oil or acetone or ether or cyclohexanone or turpentine oil or turpentine or Tianna solution or dipentadiene or said mixture.
The organic copper bactericide 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 organic copper bactericide 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 done further to resolve and explanation:
Embodiment 1: 100 gram copper sulphate, 450 gram disproportionated rosin acid potassium, 1000 milliliters of turpentine oil, 1000 ml waters were stirred 1-2 hour, left standstill two hours, getting supernatant is the organic solution of dehydro copper abietate.Add surfactant in the separating obtained organic solution, its ratio is: organic solution 500-800 part, 150 parts in surfactant fully stirs, and obtains the organic copper bactericide.
Embodiment 2: respectively 150 gram copper sulphate are dissolved in 1000 ml waters, 800 gram potash soaps are dissolved in 1600 ml waters.After both mixing, heat 50 ℃, stir two hours with product press filtration drying under 50 ℃ of temperature, get former powder.Get former powder 500 grams and be dissolved in 1000 milliliters of turpentine oil, add 100 milliliters of surfactants again, stir, leave standstill, the gained supernatant is this product.
This kind organic copper bactericide is applied on the citrus, the efficient of preventing and treating of anthracnose is reached 95%, the efficient of preventing and treating of canker reaches 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 and render a service raising 10-20%.The efficient of preventing and treating to watermelon anthrax reaches 98%.
