Abstract
The invention relates to a pyrimethanil aqua, which comprises pyrimethanil, acid and water as preparation raw materials, wherein under the auxiliary action of the acid, the pyrimethanil can be dissolved in the water completely to obtain an aqua. Compared with the prior art, the pyrimethanil aqua uses the aqua to replace missible oil, wettable powder and suspending agent, and does not use an organic solvent and cause dust pollution so that pollutant stains are not remained on the surfaces of fruits and vegetables, and drug injuries are not easy to happen.
Description
Technical field
The present invention relates to a kind of phonetic mould amine preparation, especially a kind of aqueous solution of pyrimethanil.
Background technology
Phonetic mould amine is a kind of new type bactericide, belongs to anilino-pyrimidine, its novel structure, and mechanism of action uniqueness is by suppressing the pathogen protein secreting, reducing some and cause the hydrolase level that parasitic necrosis is relevant with pathogen.Inhale conduction and fumigation action in phonetic mould amine has simultaneously, arrive sprayings such as flower, the young fruit position kill pathogens that is beyond one's reach after the dispenser rapidly, drug effect soon and stablize.The drug effect of phonetic mould amine is to temperature-insensitive; under relatively low temperature, use; its protection and result of treatment are good equally; can prevent and treat gray mold of cucumber, graw mold of tomato, grey mould fruit rot of strawberry, grey mould rot of pea, leek gray mold, pear scab and spot defoliation etc., and use all there is remarkable result in early, middle and late any time phase of plant morbidity.
Because phonetic mould amine is with the mechanism of action difference of triazole type, dithio formate class, benzo imidazole class and the carbamates (as the mould prestige bactericide of second) used now, no cross resistance, thereby antagonism pathogen or responsive germ are all effective, especially the botrytis cinerea that non-anilino-pyrimidine series bactericidal agent commonly used has been developed immunity to drugs is effective, and the scab that occurs on gray mold on grape, strawberry and vegetables, the ornamental plants and apple, the pears is had remarkable prevention effect.
Phonetic mould amine is the colourless crystallization body, 96.3 ℃ of fusing points; Density 1.15 (20 ℃); Vapour pressure 2.2*10
-3Pa (25 ℃).Dissolubility: water 0.121g/L (25 ℃); Acetone 389g/L.Methyl alcohol 176g/L; Chloromethanes 1000g/L; Cyclohexane 23.7g/L; Toluene 412g/L.Because phonetic mould amine solvability in water is little, in existing technology, generally only be processed into wetting powder, missible oil, suspending agent use, as prevent and treat crop gray molds such as cucumber, tomato, in premorbid or their early stage dispenser, use 40% phonetic mould amine 25～95g for every mu, convert 800～1200 times in water, mu water consumption 30～75kg, every medication in 7～10 days once, dispenser is 2～3 times altogether.Season of growth is prevented and treated gray mold needs dispenser generally more than 4 times the time, for avoiding producing resistance, also will be used alternatingly with other bactericide sometimes.But, owing to phonetic mould amine wetting powder, suspending agent are formulated as suspension when using, on plant and fruit face, often leave the spot of soup, cause outward appearance to pollute; And have more solvent to exist in the phonetic mould amine missible oil product, and be easy to generate poisoning after the use, can produce pollution to plant and environment equally.
In view of this, necessaryly provide a kind of phonetic mould amine preparation that can not pollute.
Summary of the invention
The objective of the invention is to: a kind of aqueous solution of pyrimethanil is provided.
For solving the problems of the technologies described above, the booster action of the present invention by acid is dissolved in water fully with phonetic mould amine and makes aqueous solution of pyrimethanil.
As a kind of improvement of aqueous solution of pyrimethanil of the present invention, described acid is inorganic acid or organic acid, or inorganic acid and organic acid mixed acid.
As a kind of improvement of aqueous solution of pyrimethanil of the present invention, described acid is one or more the combination in hydrochloric acid, phosphoric acid, lactic acid, salicylic acid, acetate, propionic acid, the benzoic acid.
As a kind of improvement of aqueous solution of pyrimethanil of the present invention, the mass percent of phonetic mould amine is 1%～50% in the described aqueous solution of pyrimethanil, and the mass percent of acid is 1%～50%.
As a kind of improvement of aqueous solution of pyrimethanil of the present invention, comprise also in the described aqueous solution of pyrimethanil that mass percent is 1%～40% surfactant.
As a kind of improvement of aqueous solution of pyrimethanil of the present invention, described surfactant be non-ionic surface active agent, anion surfactant, cationic surfactant, zwitterionic surfactant in one or more combination.
Compared with prior art, the present invention substitutes missible oil, wetting powder, suspending agent with aqua, without organic solvent, and no dust pollution, therefore the spot that can not stay pollution for the fruit and vegetable surface is difficult for producing poisoning.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, the present invention describes with following specific embodiment, but the present invention is limited to these examples absolutely not.The following stated only is the present invention embodiment preferably, only is used to explain the present invention, can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that all any modifications of being made within the spirit and principles in the present invention, be equal to replacement and improvement etc., all should be included within protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with appended claims.
The present invention is dissolved in water by phonetic mould amine to make aqua fully under the booster action of part organic acid or inorganic acid, can add surfactant in preparation, also can add surfactant in use again.Be dissolved in the water equally fully after the aqueous solution of pyrimethanil dilution during use, form transparent solution, bring into play bactericidal action better thereby under the effect of surfactant, sprawl infiltration preferably.In the aqua without organic solvent, used auxiliary acid in environment, can comparatively fast degrade or by plant as nutrient absorption, compliance with environmental protection requirements.
