Description
Technical field
The invention belongs to the composition pesticide preparing technical field, be specifically related to the granulae effervescentes and preparation method thereof and application of the composition pesticide of an allyl group isosulfocyanate and pyrethroid.
Technical background
Allyl group isosulfocyanate is one of the main component of the essential oil of the roots of some plants and seed, mustard oil for example, and it can obtain with steam distillation from the seed or the horseradish of black mustard flower, so their popular name also is athomin.Allyl group isosulfocyanate is in China's suitability for industrialized production, mainly as the organic synthesis raw material, also as food flavor.In recent years, some experts that are engaged in pesticide science research of China carry out extensive experimentation research and learn, allyl group isosulfocyanate has good smoked killing effect to grain storage pest, the fumigating insecticide that also can be used as booth and soil insect, expectation can replace the ozone layer that destroys in the atmosphere and the old fumigating insecticide Celfume of harm humans living environment.
The volatility height of allyl group isosulfocyanate, vapour concentration is big, has the strong impulse smell, and tool breaks tear, when dispenser operating personnel is easily produced injury.
Pyrethroid insectide is a class bionic pesticide, and it has efficiently, the characteristics of low toxicity, wide spectrum, but uses insect easily it to be produced resistance for a long time.It has tag, stomach poison function, some pyrethroid also has certain smoked killing effect, is to make the primary raw material of electric mat as PH etc.
Summary of the invention
First purpose of the present invention is the granulae effervescentes of the composition pesticide of development allyl group isosulfocyanate and pyrethroid.
Second purpose of the present invention is the preparation method who proposes the granulae effervescentes of this composition pesticide.
The 3rd purpose of the present invention is the application of this composition pesticide in cultural control and storage pest control.
Main technological route of the present invention is: allyl group isosulfocyanate is mixed into the new insecticide of a class respectively in proportion with the pyrethroid insecticide, and the applicant is named as the agent of grand strength series pesticide with it.That this series pesticide agent has is stifling, tag and the stomach toxicity triple role, and its drug effect is higher than single agent, and has enlarged insecticidal spectrum.And, because the vapour concentration of the simple allyl group isosulfocyanate preparation of concentration ratio of isothiocyanates is low in the mixture preparation, therefore, breaks tear sexual stimulus smell and reduce, help the dispenser personnel operation.Composition pesticide of the present invention is that a class is efficient, the environment friendly agricultural of wide spectrum, environment-friendly type, both can be used as the control that fumigating insecticide is used for storage pest, can be used as the control of vegetables, fruit and field crop insect again.Be specially adapted to the control of insect of greenhouse crops.This is first allyl group isosulfocyanate to be used for mixed pesticide, is first allyl group isosulfocyanate and pyrethroid insectide to be mixed into the new insecticide of a class.
The present invention is achieved through the following technical solutions:
A kind of granulae effervescentes of composition pesticide, it comprises allyl group isosulfocyanate and pyrethroid, and component by weight is as follows:
Allyl group isosulfocyanate 5-1;
Pyrethroid 0-5;
Solvent 5-22;
Carrier 80-90;
White carbon 10-15;
Above-mentioned raw materials mixed in reaction ax promptly obtain described composition pesticide.
Described pyrethroid is selected from the wherein a kind of of beta-cypermethrin, allethrin, Prallethrin or cyfloxylate.
Described solvent is selected from absolute ethyl alcohol.
Described carrier is selected from citric acid+sodium carbonate or citric acid+sodium bicarbonate.
The applicant optimizes following prescription through a large amount of screenings:
Optimization formula-1
By weight, component is as follows:
Allyl group isosulfocyanate 4;
Pyrethroid 1;
Other compositions are same as above.
Optimization formula-2
In weight ratio, component is as follows:
Allyl group isosulfocyanate 2;
Pyrethroid 1;
Other compositions are same as above.

Pyrethroid 2;
Other compositions are same as above.
Optimization formula-4
In weight ratio, its component is as follows:
Allyl group isosulfocyanate 1;
Pyrethroid 0;
Other compositions are same as above.
The method for preparing the granulae effervescentes of above-mentioned composition pesticide, according to following steps:
1) by weight, in reaction ax, adds allyl group isosulfocyanate and/or pyrethroid, begin to stir, the raw material agricultural chemicals is mixed;
2) in the raw material agricultural chemicals of step 1), add absolute ethyl alcohol, make mother liquor;
3) to step 2) mother liquor in add the described carrier of claim 4, make hilum;
4) in the hilum of step 3), add white carbon, be product after the stirring.
In preparation of the present invention, raw materials used and production equipment all must be dry anhydrous.Preparation is necessary abundant stirring of step respectively, reaches to mix, and as if raw materials such as citric acid or sodium carbonate or sodium bicarbonate caking, could use after preceding pulverizing earlier of adding reaction ax and the drying.
The applicant proves that by a large amount of Application Examples composition effervescent agent of the present invention can use in storage pest and agricultural insect pests control.Wherein being applied in of cultural control has outstanding effect in the greenhouse crops control of insect, and the greenhouse crops control of insect is a very difficult problem before the present invention proposes.
It is earlier container to be contained a certain amount of clear water that the granulae effervescentes of composition pesticide of the present invention uses (dispenser) method, drops into composition pesticide granulae effervescentes of the present invention by consumption then; Or in the container of earlier granulae effervescentes being packed into, after add water again; Or granulae effervescentes is sprinkling upon soil surface, water spray then.The granulae effervescentes of composition pesticide of the present invention is met behind the water citric acid and sodium carbonate chemically reactive immediately, rapid CO
2Impel the rapid same CO of medicament steam
2Volatilization is diffused into the space of being deployed to ensure effective monitoring and control of illegal activities together.
