Abstract
An emulsified oil as agricultural chemical for preventing and eliminating diseases and mite contains oleic acid (10-30%), copper sulfate (5-25%), sodium hydroxide (3-10%), organic solvent (50-70%) and emulsifier (10-15%). Its advantages are high stability, no environmental pollution, and convenient application.
Description
The invention belongs to agricultural chemicals, is to be used for corps diseases specifically, and the sterilization of mite insect, the mite emulsifiable concentrate pesticide goes out.
Dogue de Bordeaux area in 1882 finds that at first copper agent can prevent the downy mildew on the grape effectively.From then on thisly be widely used by copper sulphate and the formulated soup of limewash, and be referred to as bordeaux mixture, it has cheap, can prepare voluntarily, but it has poor stability, can only be now with the current, and the formulation operations trouble, and can not mix use with other agricultural chemicals, also very easily bring out the generation of mite evil.
In recent years, though a kind of effective organic copper preparation is abroad arranged, the TC-90 effective ingredient of developing as U.S. Tennessee company is fatty acid copper, copper abietinate, because dependence on import costs an arm and a leg, the use cost height can not be extensive use of.
The purpose of this invention is to provide a kind of emulsified oil of copper salt of fatty acid as disinfectant and miticide, overcome the defective of the said goods, keep and improve the bactericidal effect of organic copper, and possess mite function extremely simultaneously, and it is high to have stability, low, the no poisoning of price, advantage easy to use.
The object of the present invention is achieved like this: with oleic acid, sodium hydroxide adds gauge water and mixed stir about at normal temperatures and pressures in proportion 30 minutes-60 minutes, add toluene again, copper-bath stirs 30 minutes standing demix, get upper layer of extraction liquid and add emulsifier and toluene, stir again and made emulsifiable concentrate in 30 minutes to be disinfectant and miticide one commodity of the present invention by name: green bacterium spirit
Composition of raw materials is as follows:
Raw material proportioning (weight per volume)
Oleic acid 10%-30%
Copper sulphate 5%-25%
Sodium hydroxid 3%-10%
Organic solvent 50%-70%
Emulsifier 10%-15%
Wherein said organic solvent is a toluene.Described emulsifier is the sterilization emulsifier that Nanjing produces through clever petrochemical corporation (complex).
Advantage of the present invention and good effect are as follows:
1, the present invention has reduced the existence of free copper, and copper ion is slowly discharged, and reduces the poisoning of copper agent, has improved the bactericidal effect of copper agent.
Product of the present invention shows through Inst. of Citrus, Zhejiang Academy of Sciences's field control effectiveness test, and the effect that product 660 solution of the present invention and 1000 times of liquid are prevented and treated citrus scab all believes admittedly that with the U.S. company can kill to such an extent that 500 times of liquid of 1000 types and 600 times of liquid phases of the green newborn copper missible oil of home products are imitative.
Table: product control citrus fruit shot hole field control effectiveness test result of the present invention
Medicament title extension rate control efficiency %
Green bacterium spirit 660 81.54 of the present invention
1000 82.22
Green newborn copper 600 78.80
Can kill (1000 type) 500 89.34
Consider that the comparative product dilution is lower than product of the present invention, product effect of the present invention is good.
2, with low cost
Relatively use the similar reagent cost close with drug effect of the present invention, product cost of the present invention is than the low approximately 20%-30% of external imported product cost, and than the domestic low 30%-70% that manufactures a product, cost is identical with bordeaux mixture.
3, stability is strong, be easy to make, can with non-strong acid, strong basicity combined use of pesticides.
Product stability of the present invention is strong, places 2 years, still can keep initial quality, does not have precipitation and suspension and exists, and compares with the bordeaux mixture of routine, has saved the trouble of field fabrication.Also can use with mutually, be beneficial to the raising various sterilization and kill mite and insecticidal effect with non-strong acid, strong basicity agricultural chemicals.
4, product of the present invention is to the non-stimulated fall out effect of mite class, and can kill the mite class, and comparative test shows that product of the present invention killing action to the mite class in existing bactericide is the strongest.And can not produce poisoning, safe in utilization.
Provide specific embodiments of the invention below
Embodiment 1:
Get oleic acid 65kg, add in water 230kg, the sodium hydroxide 9.6kg input reactor and stirred 30 minutes, get copper sulphate 31kg and add entry 115kg dissolving and make behind the copper-bath, add toluene 150kg again and stirred static layering 30 minutes with adding in the reactor, separate and remove lower layer of water, get upper layer of extraction liquid 178kg, add emulsifier 57kg, toluene 143kg, stirred 30 minutes, and promptly got finished product of the present invention.
Embodiment 2
The material proportioning (bulking value) that makes product of the present invention by embodiment 1 described step is as follows:
