The constituents of the suspension glue agent medical film do not have toxic or side effects, and the suspension glue agent medical film can be washed completely with water. The present invention has the advantages of simple production, convenient use and wide market prospect.
Description
The present invention relates to sterilization pesticide and plant growth regulator, particularly a kind of film forming glue hangs the formulation agricultural chemicals.
Existing agricultural chemicals, be sprayed at plant surface after, poly-beading can not form continuous medicine film, can only be sporadicly, distribute intermittently, cover inhomogeneous.Expose to the weather, highly volatile and decomposition are also very easily washed away by sleet, and drug effect can not be lasting.The result have to spray repeatedly, wasting manpower and material resources so not only, and effect is also bad.Most agricultural chemicals mix the back unstable chemcial property, can not long term storage, can only promptly join i.e. usefulness, and give and sell and use brings very big inconvenience.And only prevent the single agricultural chemicals function of damage by disease and insect.In a word, the spraying mode of existing agricultural chemicals can not be not fully exerted its drug effect.General Physics film forming agent such as high fat film after the blade face forms rete, though can play the effect of isolating germ, stop germ to adhere to and infect the blade face, and to the spore bacterium colony that has formed on the plant, film forming agent can only play covering role, can not play killing action.Germ still can continue survival under film and breeding enlarges.So film forming agent has only prophylaxis effect, and there is not the effect of curing the disease.
The objective of the invention is to overcome the above-mentioned shortcoming of prior art, and a kind of drug effect height and lasting medicine are provided, chemical property is stable, and has the medicine film colloidal suspending agent of multi-functionals such as plant growth regulating and physics film concurrently.Not only play buffer action, stop infection process and can kill existing germ, make it can not continue expansion again.
Medicine film colloidal suspending agent of the present invention (commercially available product) contains following composition (weight %):
(a) film forming agent of a kind of or its mixture composition in 12～16 carbon alcohol, content is 20～80%;
(b) bactericidal agent of soluble copper salt composition, content is 2～5%,
(c) all the other are aqueous solvent.
Mantoquita in the above-mentioned medicine film colloidal suspending agent should be selected the weak acid mantoquita for use, preferably Schweinfurt green or propionic acid copper etc.Can also be added with the surfactant that octyl amine ethyl-glycinate is formed in the mantoquita, content is 1～4% of whole medicine film colloidal suspending agent, to strengthen the sterilization effect of mantoquita.Octyl amine ethyl-glycinate can be sodium salt or calcium salt.Here mantoquita easily generates precipitation as strong acid salts such as employing copper sulphate.Facts have proved in a large number, with the best bactericidal agent of carbon alcohol film adapted be Schweinfurt green etc., its film-formation result, sterilization effect and stability obviously are better than other agricultural chemicals.
Can also add plant growth regulator such as methyl or naphthalene propionic acid in the above-mentioned film forming agent carbon alcohol, absorb for plant leaf surface.
Medicine film colloidal suspending agent of the present invention is widely used in vegetables, wheat and the fruit tree etc. in the plant.
The preparation method of medicine film colloidal suspending agent of the present invention comprises that the following step poly-:
(1) a kind of or its mixture in 12～16 carbon alcohol is heated to 70～90 ℃ and makes it fusing;
(2) the mantoquita bactericidal agent is soluble in water;
(3) the bactericidal agent aqueous solution is mixed with the carbon alcohol of fusing in (1), make each composition reach the content described in the claim 1.
Can be mixed with the complexed surfactant that octyl amine ethyl-glycinate is formed in the bactericidal agent aqueous solution among the preparation method (2) of medicine-feeding film colloidal suspending agent, itself also certain bactericidal action of tool and can be advanced a bactericidal action of strengthening Schweinfurt green after the Schweinfurt green reaction.
The machining process route of medicine film colloidal suspending agent as shown in Figure 1.
Below describe a specific embodiment of the present invention in detail.
Get 40 grams, 16 carbon alcohol, be heated to 80 ℃, treat that its fusing back adds 40 gram methyls, fully stir, make its even mixing.12～16 carbon alcohol is high-carbon fatty alcohol, is generally solid.In 10 ml waters, add 3 gram copper acetate water soluble salts in addition, add 2 gram octyl amine ethyl-glycinates (commercially available) again, stir the sterilization complex compound that makes its formation stable.Copper acetate is here as bactericidal agent, and octyl amine ethyl-glycinate also has bactericidal action, but mainly is to make surfactant, and with the Schweinfurt green generation novel substance that reacts.Then the mixed liquor of bactericidal agent and auxiliary agent is added in the carbon alcoholic solution, adds 2 gram suspending agents such as carboxymethyl cellulose etc. simultaneously, stir, get final product finished product.Finished product is blue white, and PH is 6.5～6.9,15～18 ℃ at freezing point.Its outward appearance of bottling back is muddy suspension.The upper strata is mainly carbon alcohol, and the middle level is bactericidal agent and auxiliary agent layer, and lower floor is a water layer.For solidifying shape, with about 80 ℃ hot water dissolving, shake up become aqueous emulsion stand-by during use at finished product below 20 ℃.
The inventor through some weak acid copper such as a large amount of tests back discovery Schweinfurt green can with octyl amine ethyl-glycinate generation complex reaction, form the stronger novel complex of a kind of sterilizing power.Significant change all takes place, and the sterilizing ability of Schweinfurt green is obviously strengthened in color, character behind the generation chemical reaction.This is the new a kind of chemical reaction that proposes in the agricultural chemicals for preliminary deduction.
Methyl is a plant growth regulator, belongs to steroids, can be dissolved in the higher alcohols in the time of 80 ℃, forms uniform mixture in colloidal suspending agent medicine film.
The formation and the mechanism of action about the medicine film are summarized as follows: asymmetric because of the higher alcohols molecule, the hydrophilic radical of polarity and nonpolar hydrophobic grouping lay respectively at the two ends of long-chain shape molecule.This just makes hydrophilic radical turn to the bottom water layer, associates together by model third constellations power and hydrone, and hydrophobic grouping turns to top, combines with bactericidal agent and plant growing auxiliary agent, forms one deck colloidal suspending agent medicine film as thin as a wafer.Under the effect of emulsifier, suspending agent, this rete complex superposition forms polymolecular layer, can produce the embedding effect to medicine and plant growth regulator.It is a kind of very thin with regard to forming at plant surface that the aqueous emulsion that is mixed with this film forming matter of medicine is sprayed cloth, the sightless continuous rete of naked eyes, thus make medicine and plant growth regulator can be attached to the surface of spraying plant.Film forming matter is intermolecular to combine with Fan Deli in aqueous emulsion, does not influence the infiltration and the dissolving of medicine or organic molecule, does not also influence the absorption and the transfer of plant surface.Schweinfurt green class Fungicidal substance is easily dissolving in water.Its molecule can freely be evenly distributed in the molecular structure of film forming matter, and keeps the function absorbed by blade and shift in film.The rete of Xing Chenging just becomes the medicine film with bactericidal action like this, can stop infecting, spreading of phytopathogen, can kill plant disease by the protein that destroys on the pathogen cell membrane again.Thereby changed the single effect that original film forming matter can only play the physics prophylaxis effect.Making it restraint bacterium, imperfect fungus, phycomycetes etc. to various bacteria such as son all has significant control killing effect, and has concurrently and suppress moisture evaporation and improve that plant is cold-resistant, the effect of drought resisting.
General dilute with water is 200～400 times during use, and the pesticide spray mode sprays routinely, is spaced apart 7～10 days, only sprays 2～4 times and gets final product.Although carbon alcohol film forming agent has wellability, can form continuous medicine film automatically on the crop blade face, must note during spraying as far as possible evenly.
The composition of the above embodiment of the present invention is combined as a whole film forming agent, bactericide and plant growth regulator, except that the effect that suppresses germ is arranged, inhale the effect of sterilization in having concurrently, simultaneously can also promote plant growing, fruit expands, and obviously improve drought resistance and the Nai Sai of crop, the remarkable result of a medicine multiple-effect is arranged.Its composition has no side effect to the people, can wash off fully after water washing.This product production technology is easy, and easy to use, chemical property is stablized, storage period is long, and good prospect for sales is arranged.This medicine film colloidal suspending agent in recent years in the land for growing field crops repetition test, has shown that the effect of its control germ reaches 85～90% with the composition of the foregoing description, can make crop yields about 20% such as plant such as celery.The juice freezing point is descended 1～2 ℃.Its remarkable in economical benefits, drop into can reach 1: 18 with the income ratio～about 20.
