Abstract

The 25% Bingdujing aqua is made up by using copper sulfate, ammonium hydrogen carbonate, urea, synergist, assistant and water, and making them pass through a chemical reaction. The tetrammine copper sulfate has the functions of deactivating pathogenic virus and inhibiting multiplication, and can promote the absorption power of plant for medicament and activate the plant growth and development so as to obtain the function of controlling virus disease with the addition of other auxiliary ingredients.

Description

Bingdujing aqua and preparation method

The present invention relates to a kind of virus and sick medicament and preparation method of preventing and treating, particularly have the pharmaceutical preparations of efficient, low toxicity, low residual hazard, three-waste free pollution.

Look into newly known through information departments' computer search, the agricultural chemicals of preventing and treating virus disease at present mainly is an organic compound, as octicin solution, ZhiBingLing(SIC) etc., except that control efficiency generally, ubiquity is poisonous to people and animals, there are " three wastes " to pollute in the production,, limited the production and the scope of application of these agricultural chemicals owing to there is above problem.

The purpose of this invention is to provide a kind of novel inorganic compound medicament of preventing and treating virus disease, it not only control efficiency be higher than the medicament that generally adopts at present, and, do not have " three wastes " in the production and pollute people and animals' low toxicity.

The object of the present invention is achieved like this, prepares the prescription that 25% Bingdujing aqua adopted to be:

Cupric sulfate pentahydrate 25-30%

Carbonic hydroammonium 30-35%

Urea 8-10%

Calcium lignosulfonate 3-5%

Polyvinyl alcohol 1-2%

Potassium permanganate 0.1-0.5%

Zinc sulphate 3-5%

Boric acid 0.5-1%

Potassium dihydrogen phosphate 1-5%

2.4—D 0.01—0.05％

Naphthyl acid 0.01-0.05%

Water 30-40%

Concrete operation method is: earlier with in copper sulphate and the carbonic hydroammonium retort by 50 ℃ in (gross water requirement 2/3rds) warm water of putting into 2/3rds of consumption separately, 65 rev/mins rotating speed is the fastest with stirring (stir and stopped in the 30 minutes 20 minutes) reaction of having a rest, intermittently stirred 6 hours, synergist and auxiliary agent added in the lump with one water of its excess-three branch and intermittently stir the companion, reacted 4 hours, it is centrifugal to take a sample, measure every technical indicator, treat that every skill virtue index adjustment filter is after standard, put into filtration, enter the panel sub-assembling platform metering packing or enter by filter and deposit jar temporary transient a storage.

Every technical indicator of its product is:

Outward appearance: navy blue liquid

Cupric tetramminosulfate content % (m/v) 〉=25%

Ammino is right 〉=and 98%

PH value 9-10

Low-temperature stability is qualified

Heat endurance is qualified

Precipitated crystal＜3%

Its active ingredient of 25% Bingdujing aqua is cupric tetramminosulfate; Chemical name: cupric tetramminosulfate, chemical structural formula: Molecular formula Cu (NH ₃) ₄SO ₄Molecular weight 227.76.It has the effect that the passivation pathogenic virus suppresses its propagation, and other auxiliary element in addition promotes the absorption of plant to medicament, the growing of activated plant, and reach the effect of control virus disease.

Through 25% Bingdujing aqua is carried out rat oral, through skin acute toxicity testing and rabbit skin, eye stimulation test, the result shows: the clean rat oral LD50 of 25% virus is female to be 3160mg/kg, male is 2610mg/kg, be 3160mg/kg through skin LD50 male and female rat, rabbit skin, eyes all there is not the obvious stimulation effect, by China's agricultural chemicals acute toxicity grading criteria, 25% Bingdujing aqua belongs to the lower toxicity agricultural chemicals.

Through field experiment, 25% virus has tangible control efficiency to crop virosis such as tomato, cotton, tobacco, capsicum, kidney bean, Chinese cabbage only, adopts 200-400 times of liquid to spray in early days, and preventive effect is all 75-90%.

The present invention is because production technology is reasonable in design, add raw materials used basic avirulence, therefore, not having " three wastes " in the production discharges, the micro-ammonia of discharging in the production process is as gas fertilizer, promote plant growth, a small amount of cleaning fluid that produces because of the trimming that stops production continues to use as raw material, and the expense slag of output can be used as fertilizer in the production.

Its technological process is as figure.

Claims (2)

1, a kind of 25% Bingdujing aqua is characterized in that being made by following prescription.
