Abstract
The present invention discloses a bactericidal composition containing organic copper, which is characterized in that the bactericidal composition contains resin acid copper as an effective component, laurocapram as a synergistic agent, and organic solvents with bactericidal functions, wherein the compounding ratio of the resin acid copper to the laurocapram is 3 to 80: 1. In addition, the bactericidal composition also contains an emulsifying agent. Compared with the prior art, the bactericidal composition adopts easily-obtained heavy oil with bactericidal functions and low cost as a solvent, so that the production cost is reduced, and the medicine effect is increased; the bactericidal composition adopts laurocapram as the synergistic agent, so that the bactericidal functions of the resin acid copper on crops and pathogenic bacteria can be improved, the medicine effect is obviously increased, and the dosage is reduced.
Description
The present invention relates to a kind of bactericidal composition that contains organic copper.
For a long time, the peasant prevents and treats the multiple diseases of multiple kinds of crops with copploid liquid, as canker, anthracnose etc.Publication number is that a kind of sterilization copploid liquid and manufacture method thereof have been narrated in the patent application of CN1161780A.It is now with the current that this sterilization copploid liquid has solved former copploid liquid, and accumulating for a long time easily produce problems such as poisoning, but this sterilization copploid liquid drug effect also is not very desirable.
The object of the present invention is to provide a kind of drug effect higher, cost is low, contains the bactericidal composition of organic copper.
A kind of bactericidal composition that contains organic copper is characterized in that it contains active ingredient copper rosinate and synergist azone, and with the organic solvent with bactericidal action, wherein the proportioning of copper rosinate and azone is 3-80: 1.
The further solution of above-mentioned bactericidal composition is that copper rosinate is chosen as copper abietinate or disproportionated rosin acid copper.
Above-mentioned bactericidal composition, its further solution contains emulsifier for it, and each components contents is as follows:
Copper abietinate or disproportionated rosin acid copper 9-40%
Azone 0.5-3%
Organic solvent 40-70%
Emulsifier is an amount of
Above-mentioned bactericidal composition, wherein said organic solvent are heavy oil, and the main component of heavy oil is a longifolene.
Compare with original technology, the present invention's employing has bactericidal action and heavy oil cheap and easy to get has reduced production cost as solvent, has improved drug effect, makes synergist with azone and can improve the bactericidal action of copper rosinate on crop and pathogen, significantly improve drug effect, reduced dosage.
Below by specific embodiment and chart the present invention is made further explanation and description:
The bactericidal composition preparation process that contains organic copper of the present invention is:
(1) in proportion that rosin and disproportionated rosin and water, highly basic and organic solvent is complete at 70-90 ℃ of following stirring reaction.
(2) add copper sulphate in above-mentioned solution, insulation reacts completely under 60-90 ℃.
(3) left standstill 3-24 hour after the reaction, get upper layer of extraction liquid, add an amount of emulsifier emulsification in upper layer of extraction liquid, the ratio in 0.5-3% adds azone again, promptly makes a kind of bactericidal composition that contains organic copper.
Embodiment 1
1:30 gram rosin adds 100 ml waters, adds 200 milliliters of heavy oil, adds 4 gram NaOH, is heated to 80-90 ℃, stirs reaction down 5 hours.
2: in above-mentioned reactant liquor, add 8 gram copper sulphate, stir reaction down 5 hours, left standstill after having reacted 6 hours, get 200 milliliters of upper strata organic solutions, add emulsifier (emulsifier is the mixture of sapn, tween and NPE-10) 30 milliliters, add 3 milliliters of azones, stir and promptly make a kind of bactericidal composition that contains organic copper.
Embodiment 2
1:30 gram disproportionated rosin adds 100 ml waters, adds 200 milliliters of heavy oil, adds 4 gram NaOH, is heated to 80-90 ℃, stirs reaction down 3 hours.
2: in above-mentioned reactant liquor, add 8 gram copper sulphate, stir reaction down 3 hours, left standstill after having reacted 6 hours, get 200 milliliters of upper strata organic solutions, add emulsifier (by the mixture of sapn, tween and NPE-10) 30 milliliters, add 3 milliliters of azones, stir and promptly make a kind of bactericidal composition that contains organic copper.
The present invention is further described in tabulation below:
