Abstract
A disinfectant for preventing and eliminating diseases of vegetables is prepared from 10-80% alcohol (80-120 portions), coptis root or phellodendron bark (3-20 portions) and baked alum (1-20 portions) and features low toxicity, low cost and high effect.
Description
The present invention relates to agricultural chemicals, specifically belong to the bactericide of preventing and treating vegetable disease.
Vegetables usually can be subjected to infecting of pathogen in growth and development process; thereby cause its metabolic disturbance; make vegetables internal physiological or external form that abnormal variation all take place; as the variable color of plant, necrosis, rot, wilt, deformity or the like, can obviously reduce the economic characters of vegetables thus.Agricultural goes up when the control vegetable disease at present, the bactericide of often selecting for use is tpn, Sukeling, thiophanate methyl etc., though these bactericide have certain preventive and therapeutic effect, but have following 3 weak points: this series bactericidal agent of one generally only is suitable for the initial stage use that disease takes place, (see that Jiangxi science tech publishing house publishes, chief editor such as Li Mingyuan " the vegetables extermination of disease and insect pest " P
21,27,40), when entering the intermediary and later stages, disease re-uses, and its drug effect obviously reduces, and can not treat and eradicate disease effectively, so, when using this series bactericidal agent,, just can cause the vegetables serious consequence of the underproduction or total crop failure significantly in case incur loss through delay medication time for some reason; Its two: these bactericide mostly are chemical synthetic drug, its toxic action is bigger, long-term a large amount of use causes serious infringement can for the mankind and environment, as its chemical name of tpn commonly used is 2,4,5, the 6-termil is to human body skin and eye is fine that spread effect just arranged, (see that Shanghai scientific and technical literature publishing house publishes, Huang Ruzeng etc. write " novel pesticide service manual " P and can be caused the fish poisoning by the water source that tpn pollutes
174); Its three: these bactericide, the cost height, price is expensive.
Purpose of the present invention just provides the bactericide of the control vegetable disease that a kind of bactericidal effect is good, toxic and side effect is little and cheap.
The object of the present invention is achieved like this: it is extremely low and have the component of good sterilization, bacteriostasis to select toxic action from plant, mineral, is prepared into bactericide.
The specific implementation of the object of the invention is to select for use the ethanolic solution of 10-80% as carrier, is dissolved with the coptis or golden cypress and alumen, and the weight proportion of each component is 10-80% ethanol 80-120 part, the coptis or golden cypress 3-20 part, alumen 1-20 part.
Its effective sterilization of the coptis among the present invention and golden cypress, antibacterial composition all are little Pi's alkali, so that both can choose wantonly is wherein a kind of.When concrete preparation, can be higher than the characteristics of golden cypress according to little Pi's alkali composition that the coptis includes,, can on the amount of selecting for use, suitably be lower than the consumption of golden cypress from the purpose that reduces cost.
The preferred ingredient of each component of the present invention and weight proportion are 50-80% ethanol 80-120 parts, golden cypress 10-20 part, alumen 5-15 part.
Be starkly lower than the coptis owing to the golden cypress price in the above-mentioned prescription, and it is more extensive to originate, can substitute the coptis by golden cypress, with further reduction product cost of the present invention, the change of its carrier concn and set of dispense ratio can be in the bactericidal effect that enhancing carrier itself is had, the bactericidal effect that further improves golden cypress and alumen.
Concrete compound method of the present invention is:
(1) presses 10-80% ethanolic solution 80-120 weight portion; The coptis or golden cypress 3-20 weight portion; Alumen 1-20 weight portion takes by weighing each component, wherein the ethanolic solution of 10-80% is that ethanol by 60-95% adds aqueous solution dilution and forms, its purpose is the coptis or the golden cypress that is soluble in ethanol with its effective ingredient of alcohol extract of high concentration, dissolves its effective ingredient alumen soluble in water with the aqueous solution.
(2) coptis or golden cypress are pulverized granulating, make solvent, soaked 8-24 hour, make active ingredient such as its little Pi's alkali fully be dissolved in the pure liquid recovery, twice filtrate of merging with the ethanol of 60-95%;
(3) alumen is pulverized, added the aqueous solution and stir, placed 4-24 hour, make in the abundant water-soluble solution of its effective ingredient alkaline potassium aluminum sulfate, reclaim, merge twice filtrate;
(4) coptis or golden cypress alcoholic solution and alumen solution are merged, be made into and contain the alcohol amount and be the alcoholic solution bactericide of 10-80%.
One of important innovations point of the present invention is organic compatibility of each component of the present invention, produced good synergy, as select for use ethanol to do carrier and the coptis or golden cypress and alumen coupling with antibacterial action, not only widened the antimicrobial spectrum of bactericide, strengthen the effectiveness of its bactericidal, also improved the effective ingredient of the coptis in the solution or golden cypress effectively.Adding alum that alumen includes also can promote the metabolism of plant to have strengthened the resistance against diseases of plant.This bactericide is compared with existing bactericide, and not only sterilization, fungistatic effect are better, but also can promote the reparation of vegetables pathological tissues when eliminating the vegetables pathogeny, strengthens the resistance against diseases of vegetables.This bactericide is early stage applicable to vegetable disease not only, also can enter mid-term to disease, the vegetables in later stage effectively treat and eradicate.
Two of important innovations point of the present invention is that the present invention has selected the main ingredient of the coptis that human body can be taken and the medicine source is wide, cheap or golden cypress and alumen effect disinfectant for vegetables, reduced the toxicity of bactericide to greatest extent, thereby avoided chemical synthetic drug to give the mankind and negative effect that environment brought, simultaneously, raw material sources of the present invention are extensive, manufacture craft is simple, so that its product price is compared with existing bactericide is also obviously on the low side.The present invention is starkly lower than tpn to the spread effect of human body skin, through being investigated, the user shows, when using tpn, there is 50% people to feel to have skin burning heat sensation, other sense of discomfort, and use bactericide of the present invention with the lineup, except that there being utmost point one or two people that ethanol is had the allergy, all the other all do not have sense of discomfort.
The present invention can be used for preventing and treating by the various types of vegetable diseases due to the pathogene infringement, as the downy mildew of vegetables, gray mold, powdery mildew, bloom disease, black spot, anthracnose etc.300-400 times of dilution with this bactericide during use sprays complete stool.
