Abstract
The invention discloses a pesticide prepared from Chinese herbal medicines, which relates to a pesticide for a greenbelt in a city and belongs to the field of pesticides. The pesticide is characterized by comprising the following raw materials, by weight, 0.5 to 10% of emamectin benzoate, 3 to 25% of algae, 1 to 12% of a surfactant, 1 to 8% of an easily degradable polymer, 2 to 15% of a stabilizing agent, 2 to 15% of a plant-growth regulator, 5 to 45% of Kaempferitrin, 8 to 25% of cedrol and 6.5 to 20% of sapogenin. The invention has the following beneficial effects: the raw materials for the biological pesticide are algae and extracts of wild Chinese herbal medicines, so the biological pesticide does not contain chemical components harmful to human bodies, which enables landscape trees applied with the pesticide not to contain residual substances harmful to human bodies; a preparation method for the biological pesticide is simple, has low cost and is convenient for popularization and application; the raw materials are easily available, processing technology is simple, cost is low, and the pesticide is suitable for industrial large-scale production and has a wide application scope.
Description
Technical field
The present invention relates to a kind of urban green belts insecticide, belong to the insecticide field, is the insecticide that a kind of Chinese herbal medicine is made specifically.
Background technology
In the today of advocating green and protection of the environment, multiple high poison and high residue chemicals are limited the quantity of or are stopped production.The agricultural chemicals such as organic phosphor, organic amine, pyrethroid, benzoyl area kind and biochemistry have made original toxicity decrease to a certain extent through compounded combination.It limits the use of scope to the reagent amount of dilution of agricultural insecticide head and shoulders above, and the agricultural product chemical residue does not far reach non-harmful requirement, and the agricultural chemicals demand that increases year by year causes the aggravation of rural environmental pollution, and its residue more can not be ignored the harm of human body.
The main insect pest of landscape tree has longicorn, wood louse, leaf miner, leaf mining tiger, scale insect, chafer etc.Wood louse is caused harm more seriously in the arbor shrub in recent years, secondly is scale insect, adopts conventional insecticide, the speed Trane etc. of slaughtering, be situated between.
Increasing for present Gansu province urban green space earth-covering greening, chemical control is still the large generation of disease and pest control and eliminates the major measure in base, worm source.China's chemical control area accounts for about 70% of whole Forest Diseases, pest control area.Doing well under the prerequisite of prediction, correctly using agricultural chemicals to prevent and treat in good time, generally can obtain good control efficiency.Domestic insecticide commonly used has avermectin, Imidacloprid, Frontline, young urea etc. goes out; Bactericide has tpn, carbendazim, triadimefon, topsin.Main application method has spraying, dusts, fumigates, dresses seed, puts cigarette etc.But because plant in the large place of property the crowd is dense usually at urban tree, can damage people's respiratory system, cause stupor or vomiting; Commercially available agricultural chemicals is that industrial chemicals is made mostly, although can kill the insect on the trees, but its residue still has larger injury to human body, the product of using this chemical pesticide often has a severe toxicity because of residual, easily cause people, animal pesticide poisoning accident, so that these medicines are not suitable for the deinsectization of urban tree, also have because the result that these pesticide products use year after year, cause polypide drug resistance and pesticide resistance to strengthen year by year, the effect after being used alternatingly is not very good yet; Numerous city dwellers wish a kind of good disinsection effect very much, and people, animal are not damaged, and to improve safety and the feature of environmental protection of pesticide products, reduce production costs simultaneously.
Summary of the invention
The insecticide that the object of the present invention is to provide a kind of Chinese herbal medicine to make overcomes existing agricultural chemicals toxic and side effect large, the defective that price is high, the present invention is to remove agricultural chemicals to the harm of people, animal, improve safety and the feature of environmental protection of agricultural product, reduce pesticide cost, improve peasant's economic benefit.
For achieving the above object, the insecticide that a kind of Chinese herbal medicine of the present invention is made is characterized in that: its raw material components weight ratio is: first dimension salt 0.5～10%, algae 3～25%, surfactant 1～12%, easy degraded macromolecular 1～8%, stabilizing agent 2～15%, plant growth regulator 2～15%, Kaempferitrin 5～45%, cedrol 8～25%, sapogenin 6.5～20%.
The preparation method of the insecticide that a kind of Chinese herbal medicine of the present invention is made is characterized in that: comprise the steps:
One, fresh algae fished for, gets after centrifugal, the removal of impurities, atomized drying 50～70 ℃ of drying 4～7h of algae of 5～50% above-mentioned processing from water;
Two, first is tieed up salt and plant growth regulator and be dissolved in the reaction vessel that organic solvent is housed, and add dried algae, after 24h is soaked in 30 ℃ of lower vibrations in constant temperature gas bath oscillator;
Three, easy degraded macromolecular is added in the above-mentioned reactor; Surfactant and stabilizing agent are poured in the redistilled water;
Four, two kinds of products of step 3 are mixed, send into high-shear emulsion machine 12000rpm speed and stir 15min, the speed with 1000rpm stirs again; 40 ℃ of temperature steam organic solvent, filter water outlet after adding Kaempferitrin, cedrol, sapogenin again, namely get the Chinese herbal medicine insecticide.
Described raw material algae is 5～50% of fresh algae.
Described algae is a kind of in Microcystis aeruginosa, chroococcoid, cytoalgae, capsule ball algae, wedge algae and the chamber ball algae.
Plant growth regulator is indolebutyric acid or methyl α-naphthyl acetate.
Easily the degraded macromolecular compound is one or more in the following material: methyl or carboxymethyl cellulose, polyvinyl acetate, polyvinylpyrrolidone, polyethylene glycol, hydroxyethylcellulose, polyvinyl alcohol, soluble starch, corn starch.
Surfactant is organic silicon surfactant.
Stabilizing agent is one or more in anhydrous sorbitol polyethylene polyethenoxy ether, sorbitan mono-laurate, polypropylene glycol oxirane ether, NaLS, dodecyl sodium sulfate or the polyethylene glycol.
Organic solvent is a kind of in methyl alcohol, ethanol, acetone, benzinum, ethyl acetate, carrene, the chloroform in the step 2.
The organic solvent that uses in the step 2 of the present invention is distilled out of in step 3, does not contain organic solvent composition in the product.
Novelty of the present invention is as carrier take algae, utilize its physical adsorbability to adsorb former medicine first dimension salt and plant growth regulator, add easy degraded macromolecular, surfactant and stabilizing agent, mix with little fertilizer after solidifying encystation, be prepared into the insecticide that a kind of Chinese herbal medicine is made.
The application process of described this product is prepared into spray solution on trees for can be embedded in the soil; Drive, kill insects, through on probation, the effect of desinsection can up to 90～95%, can effectively protect crops not to be subjected to the infringement of insect.
The insecticide that a kind of Chinese herbal medicine of the present invention is made, its beneficial effect is: the raw material of biopesticide of the present invention is algae and wild Chinese medicinal herbs extract, therefore this biopesticide does not contain harmful chemical analysis, make the landscape tree of using this agricultural chemicals not have harmful residuals, the preparation method of biopesticide of the present invention is simple, cost is low, and is easy to utilize; Raw material is easy to get, processing technology is simple, with low cost, be fit to industrial scale production, be widely used.
