Abstract
The present invention relates to a natural pyrethrin emulsifiable solution preparation characterized in that 0.2 to 0.7% of the pyrethrin content in original medicines of BHT or ellagic acid is added into the refined natural pyrethrin original medicines for thorough stir and even mixture; 6 to 10% of the pyrethrin content in the original medicines of PB or asarinin is added for stir and dissolution; 10 to 30% of the pyrethrin content in the original medicines of emulsifier is added; then right quantity of petroleum ether is added; thus, a series of natural pyrethrin emulsifiable solution preparations with different pyrethrin contents is prepared. The present invention has the advantages of high effect, no residue, pyrethrin decomposed into water and carbon dioxide in nature and low toxicity; the mass produced products of the present invention can replace the agricultural chemicals, which has high toxicity and is greatly harmful to human beings, such as organic chloride agricultural chemicals, orgnaophosphorus agricultural chemicals, etc. step by step.
Description
Technical field
The present invention relates to pesticidal preparations, specifically natural pyrethrin missible oil preparation.
Background technology
Mostly existing pesticide original medicine and pesticidal preparations are organochlorine class, organic phosphates, carbamate or pyrethroid, these agricultural chemicals use later and leave farming residual (residue of pesticide) on the plant, bring many harm to the mankind, serious environment pollution, and the pesticide resistance of insect is more and more stronger, and having only increases dosage gradually and just can overcome insect pest.
Summary of the invention
The purpose of this invention is to provide a kind of non agricultural chemical residuum, to person poultry harmless, natural pyrethrin missible oil preparation efficiently.
Natural pyrethrin missible oil preparation of the present invention is to make with following raw material and method:
Use refined natural pyrethrosin primary medicine, the tannic acid or 2 that adds the 0.2-0.7% of pyrethrin content in the former medicine, 6 di-tert-butyl-4-methy phenols (BHT), fully behind the stirring and evenly mixing, the magnificent asarinin that adds the 6--10% of pyrethrin content in the former medicine again stirs molten, the emulsifier that adds the 10--30% of pyrethrin content in the former medicine again adds the series natural Dalmatian chrysanthemum cream preparation that an amount of benzinum gets different pyrethrin content again.
The present invention compared with prior art has following characteristics:
1, efficient, drug effect of the present invention is 4-8 a times of cypermethrin.
2, noresidue, pyrethrin resolves into water and carbonic acid gas at occurring in nature.
3, toxicity is extremely low, and preparation toxicological test process proof is nontoxic to rabbit, and no sensitization is little malicious agricultural chemicals.
The natural problem that the plain cream preparation of chrysanthemum has solved residue of pesticide effectively of removing of the present invention, it is produced in a large number, can progressively substitute the contour malicious agricultural chemicals of organochlorine class, organic phosphates that the mankind is produced very big harm.
Specific embodiments
Embodiment 1:
Accurately weighing and analyze the content of pyrethrin in the refined natural pyrethrosin primary medicine, add pyrethrin content in the former medicine 0.7% 2,6 di-tert-butyl-4-methy phenols, fully behind the stirring and evenly mixing, 5% the magnificent asarinin that adds pyrethrin content in the former medicine again stirs molten, with proper amount of acetone solution dilution emulsifier (farming breast 2201), adds 15% emulsifier of pyrethrin content in the former medicine again, adding benzinum to active principle again is 10%, gets natural pyrethrin missible oil preparation.
Embodiment 2:
Accurately weighing and analyze the content of pyrethrin in the refined natural pyrethrosin primary medicine, 0.3% the tannic acid that adds pyrethrin content in the former medicine, fully behind the stirring and evenly mixing, 8% the Butacide that adds pyrethrin content in the former medicine again stirs molten, with proper amount of acetone solution dilution emulsifier (farming breast 5201), add 20% emulsifier of pyrethrin content in the former medicine again, adding benzinum to active principle again is 5%, natural pyrethrin missible oil preparation.
The former medicine of pyrethrum among the embodiment 1,2 is to get according to following method preparation:
In the Dalmatian chrysanthemum extract, add its weight 6-12 petroleum ether solvent doubly, add the stabilizing agent of the 3-6 ‰ of Dalmatian chrysanthemum extract weight then, and dissolved 0.5-1.5 hour down at 40-60 ℃; Under 30-40 ℃, filter to get filtrate; In temperature is concentrated filtrate under 70-80 ℃, vacuum 0.2-0.7 condition, adds the anhydrous slufuric acid of the 4-10% of Dalmatian chrysanthemum extract weight in concentrate, refilters, and adds the former medicine of Dalmatian chrysanthemum that benzinum gets different pyrethrin content in filtrate as required.
Claims (1)
1, a kind of natural pyrethrin missible oil preparation, it is characterized in that using refined natural pyrethrosin primary medicine, the tannic acid or 2 that adds the 0.2-0.7% of pyrethrin content in the former medicine, 6 di-tert-butyl-4-methy phenols, fully behind the stirring and evenly mixing, the magnificent asarinin that adds the 6-10% of pyrethrin content in the former medicine again stirs molten, adds the emulsifier of the 10--30% of pyrethrin content in the former medicine again, adds the series natural pyrethrin emulsion preparation that an amount of benzinum gets different pyrethrin content again.
