Abstract
The present invention relates to a method for preparing an organic copper bactericidal acaricide. Dehydro potassium (sodium) abietate, copper sulphate and organic solvent are used as raw materials; at the normal temperature and the normal pressure, water is added and then is mixed with the raw materials to be stirred according to a certain proportion; after reaction, reaction liquid is transferred to a settling tank and stands until water and oil are separated; extract liquid at the upper layer is taken; after an emulsifying agent is dropped to be mixed and stirred with the reaction liquid, a finished product of the bactericidal acaricide can be obtained. The present invention has the advantages of convenient use, stable emulsion, good adhesiveness and spread performance, rain wash resistance, no phytotoxicity generation when specified concentration is applied, acaricidal action, high acaricide effect and long persistent period after acaricide application, a bactericidal protective film can be formed on the surface of a plant, and copper ions are slowly released.
Description
The present invention relates to pesticide production technology, specifically, the present invention relates to dehydrogenation abietic acid potassium or sodium salt, copper sulphate and turpentine oil is the method that raw material is produced organic copper agent used as bactericide and acaricide missible oil.
Copper agent starts from 1882 as the bactericidal agent for preventing and treating plant disease.Dogue de Bordeaux area downy mildew of garpe was very serious at that time, the mixed liquor that Frenchman Millardet chances on copper sulphate and limewash is sprayed on the grape has good preventive effect to downy mildew of garpe, so this very fast popularization of method that prevents and treats downy mildew of garpe is come, the soup that people are made into this copper sulphate and limewash is bordeaux mixture.So far, bordeaux mixture is still all kinds of orchards and uses one of protective fungicide more widely.Though bordeaux mixture has protection effect preferably, exist that liquid medicine stability is poor, the formulation operations trouble, can not mix use with other agricultural chemicals and easily bring out shortcoming such as the big generation of orchard mite class.For overcoming the shortcoming of bordeaux mixture poor stability, formulation operations trouble, inorganic salts wetting powders such as copper oxychloride, basic copper sulfate occurred, but they use at apple, pears etc. and easily produce poisoning on to the crop of copper ion sensitivity.The appearance of organic copper bactericide has overcome the above-mentioned shortcoming of bordeaux mixture, as the TC-90[Farm Chemicals of U.S. Tennessee company development, 127, No.6,62 (1964)] be a kind of effective organic copper preparation, its effective ingredient is fatty acid copper and copper abietinate, but fails to be extensive use of.
Purpose of the present invention and task are: with dehydrogenation abietic acid potassium or sodium salt, copper sulphate and organic solvent is that raw material is produced organic copper agent used as bactericide and acaricide.
The present invention is to be raw material with dehydrogenation abietic acid potassium or sodium salt, copper sulphate and organic solvent, at normal temperatures and pressures, stir behind the mixing and water adding by a certain percentage, after the reaction reactant liquor is changed in the settling tank, leave standstill to the separation of water oil, get upper layer of extraction liquid, drip and promptly get the agent used as bactericide and acaricide finished product after emulsifier stirs.
The present invention directly is extracted into organic solvent with the effective ingredient dehydro copper abietate, effective ingredient rate of recovery height with the extract of organic solvent as the dehydro copper abietate of dehydrogenation abietic acid potassium or sodium salt and copper sulphate reaction back generation.
Each proportion of raw materials of the present invention is as follows:
Dehydrogenation abietic acid potassium or sodium salt 30%-50%
Copper sulphate 8%-20%
Organic solvent 3%-55%
Extract with above-mentioned raw materials makes adds emulsifier, and the ratio of extract and emulsifier ratio is as follows:
Emulsifier: extract=15-30: 100
Concrete, the present invention implements in the following manner:
With dehydrogenation abietic acid potassium or sodium salt, copper sulphate and turpentine oil is raw material, at normal temperatures and pressures, stir behind the mixing and water adding by a certain percentage, react after 5 hours, reactant liquor is changed in the settling tank, leave standstill 24 hours after, water oil separates, get upper layer of extraction liquid, drip emulsifier TX-10 mixing stirring and promptly get the agent used as bactericide and acaricide finished product after 40 minutes.
Choose turpentine oil as organic solvent, turpentine oil can not only make the effective ingredient dehydro copper abietate fully be dissolved in wherein, and itself also be good miticide, make this medicament tool acaricidal action, overcome the shortcoming that causes the big generation of two spotted spider mite after other copper agent dispensers.
Choosing TX-10 is emulsifier, and the processing formulation is a missible oil, makes this product have good stability of emulsion behind thin up
Each proportion of raw materials is as follows:
Dehydrogenation abietic acid potassium or sodium salt 30%-50%
Copper sulphate 8%-20%
Turpentine oil 35%-55%
Extract with above-mentioned raw materials makes adds emulsifier TX-10, and the ratio of extract and emulsifier TX-10 proportioning is as follows:
TX-10: extract=15-30:100
Specific embodiment is as follows:
Removing 18 kilograms of 26 kilograms of hydrogen abietic acid potassium or sodium salts, 15 kilograms in copper sulphate, 23 kilograms in turpentine oil, water puts into retort and mixes and stirred 5 hours, change in the settling tank, leave standstill 24 hours after, get 20 kilograms of upper layer of extraction liquid, drip emulsifier TX-105 kilogram and mix stirring 40 minutes, get product.
Product of the present invention and the contrast of other copper agent results of use
| Name of product | To the citrus ulcer preventive effect | To citrus red mite preventive effect (insect population go down rate) |
| Dehydro copper abietate | 91·2％ | 25·7％ |
| Copper oxychloride | 82·7％ | -12·5％ |
| Bordeaux mixture | 69·3％ | -15·3％ |
The preventing iron-smelting effect of dehydrogenation abietic acid copper products also has the better prevention effect apparently higher than oxygen, copper chloride and bordeaux mixture to citrus red mite on to the control of citrus ulcer, is the ideal substitute of bordeaux mixture.The present invention is easy to use, emulsion-stabilizing, adhesivity that tool is good and plate-out ability, and rain drop erosion; can form a sterilization diaphragm on the plant surface after the dispenser, copper ion slowly releases, the drug effect height; lasting period is long, can not produce poisoning in the regulation working concentration, the tool acaricidal action.
