Abstract
A kind of stability of pesticide formulation that contains water-disintegrable agricultural chemicals as active component is characterized in that adding anhydrous not cream III and optionally adds epoxidised linseed oil and/or epoxidized soybean oil comes stabilization formulations.
Description
The present invention relates to a kind of new stability of pesticide formulation, also relate to its production method with and application method.
In general, contain the pesticidal preparations of water-disintegrable agricultural chemicals, in storage process, be subjected to the influence of the kind and the storage requirement of preparation, can make active component generation hydrolysis as active component.Therefore, for such pesticidal preparations, be necessary its stability is improved.For example, have a Japanese Patent Application Publication file 5440/1965 just to disclose a kind of stable fungicide preparation, it contains the mixture, calcium sulfate dihydrate (dihydrate gypsum) of organomercurial compound and organo-arsenic (III) compound rilanit special or the higher fatty acid as carrier and 0.1～3%.But this known method for stablizing water-disintegrable agricultural chemicals of the present invention, is not highly effective.
The present invention provides a kind of stability of pesticide formulation that contains water-disintegrable agricultural chemicals as active component now, it is characterized in that adding the anhydrous gypsum III and stablizes said preparation.
The present invention also provides the stability of pesticide formulation of a kind of water-disintegrable agricultural chemicals as active component, it is characterized in that adding anhydrous gypsum III and epoxidised linseed oil and (or) epoxidized soybean oil stablizes said preparation.
The present invention further provides and a kind of the anhydrous gypsum III is added water-disintegrable agricultural chemicals to produce a kind of method of stability of pesticide formulation.
The present invention also provides a kind of method of producing stability of pesticide formulation, be about to anhydrous gypsum III and epoxidised linseed oil and (or) epoxidized soybean oil adds in the water-disintegrable agricultural chemicals.
In a word, have found that stability of pesticide formulation prepared in accordance with the present invention, can be widely used in aspects such as agricultural, gardening and health.
The anhydrous gypsum III is added the active component that to stablize water-disintegrable agricultural chemicals in the pesticidal preparations of the present invention, and can any reaction not arranged to its physical property, should be considered to extremely to make us being surprised, because use known calcium sulphate in the preparation that reality is used, not expecting has above-mentioned character.
When add anhydrous gypsum III and epoxidised linseed oil with (or) epoxidized soybean oil cooperates, the active component that can further stablize water-disintegrable agricultural chemicals also should be considered to extremely to make us being surprised.The present invention also finishes according to this discovery.
Just add the anhydrous gypsum III, just produced the aforementioned stable effect.The anhydrous gypsum III is so-called dissolubility anhydrous gypsum, γ-CaSO
4" half anhydrous gypsum ".As for definition, see also the handbook of inorganic chemistry of Gmelins, the B of calcium portion, the 3rd fascicle, 28, the 679 pages of series numbers and the chemical publishing house of following several pages of Weinheim/Bergstra β e, the 1961st year version to the anhydrous gypsum III.If with calcium sulfate dihydrate (CaSO
42H
2O) calcium sulfate hemihydrate (bassanite, CaSO
41/2 H
2O) anhydrous gypsum I or anhydrous gypsum II replace, the then very easy decomposition of active component.
Stability of pesticide formulation of the present invention is for the agricultural chemicals manufacturing industry provides a kind of creationary technology.Therefore, the present invention is applicable to industrialization, and has tangible technological merit.
The water-disintegrable agricultural chemicals that is used for stability of pesticide formulation of the present invention is hydrolyzable reactive compound, and it is generally used for plant protection and prevents and treats the household damage by disease and insect.It is insecticide preferably, bactericide, miticide, nematocide, weedicide or plant growth regulator.The example of reactive compound comprises following all cpds, but is not limited to following compound.
