Its advantages are high effect, easy degradation, and no poison and residue.
Description
Affiliated technical field: the invention belongs to agricultural and use insecticide, particularly about a kind of environment-friendly pesticide.
Background technology: at present with the plant extraction liquid prevention and elimination of disease and pests, can shield to environment, but usually improper because of processing method sometimes, effect is not very remarkable, and has used synthetics more or less, and environment has been produced pollution in various degree.As number of patent application 96115603 vegetable insecticides, it provides a vegetative insecticide and manufacture method, this vegetable insecticide comprises that natural plants vomiting nut, crotons, semen armeniacae amarae, Chinese honey locust, white pepper, fructus hordei germinatus etc. go out its active component through volatile solvent methyl alcohol, ethanol or with the mixed liquid dipping of chloroform, make after the mixing, crops or plant insect are had very strong lethality.Also have number of patent application: 92111411 vegetable insecticide, it by multiple Chinese herbal medicine, solvent, floating agent through raw material pulverizing, extraction, to concentrate processing formulated.And number of patent application: 95108844, natural botanical insecticide, it is the natural botanical insecticide of a kind of prevention and control plant, vegetables, fruit and diseases and pests of agronomic crop.It is to adopt compound Chinese herb, surfactant, kerosene and water preparation to make through lixiviate and stirring.Go up several inventions part that comes with some shortcomings, it mainly shows the following aspects:
1, extracting method generally all take poach, with the direct method such as extraction of alcohol, recovery rate is lower, wastes raw material, and causes the cost height, is not suitable for large-scale production.
2, in leaching process, all added harmful synthetics basically,, plant and people and animals have been caused in various degree injury as chloroform, kerosene etc.
3, above several product all is missible oil or solution, and the deficiency of these botanical pesticide maximums is to go bad poor stability, the easy decomposition, and loses drug effect.
4, some invention is because the medicinal material kind is single, and the desinsection scope is narrower.
Summary of the invention: the purpose of this invention is to provide a kind of environment-friendly pesticide, it is pollution-free, easy degraded, low-residual, hypotoxicity, wide adaptability, good disinsection effect, thereby has avoided the pollution to environment of the generation of pest resistance to insecticide and traditional chemical agricultural chemicals effectively.
Technical scheme of the present invention is: design a kind of environment-friendly pesticide, its preparation method is: it selects for use Chinese medicinal plant to make the primary raw material of insecticide, and the primary raw material after removal of impurities pulverized adopts microwave, ultrasonic to handle extraction process and extract respectively respectively, and the different soups that will extract again are mix preparation in proportion.
The primary raw material of described environment-friendly pesticide is: stemonine 16%-30%, thunder godvine 10%-25%, crotons 10%-30%, monkshood 5%-15%, kuh-seng 8%-15%.
Described raw material is added with: Sargent gloryvine 5%-10%, Rhododendron molle 3%-5%, trifoliate jewelvine 6%-10%.
Described raw material is added with: grass-leaved sweetflag 1%-2%, sesamin 0.3%-0.5%, castor-oil plant 0.2%-0.4%, tea 0.1%-0.3%, limonoid 0.2%-0.5%.
Characteristics of the present invention are:
1, extraction process advanced person:
Because prior art only utilizes coarse extracting method such as immersion, poach, cause extraction time long, recovery rate is low, is unfavorable for industrial production.We have taked advanced modern extracting method, and for example processing method such as microwave, ultrasonic is extracted, and have formulated different extraction processes according to the characteristic of different medicinal materials.
2, adopt the Microwave Extraction technology
Microwave energy destroys the cell wall of plant rapidly, but can not change the basic structure of its inner active ingredient, thereby can improve recovery rate effectively.Medicinal material is put into solution and used microwave treatment a period of time, find that after testing each content of effective obviously increases.
3, adopt ultrasonic wave extraction
The basic principle of ultrasonic wave extraction mainly is that the leaching that utilizes cavitation effect of ultrasonic waves to quicken effective ingredients in plant is extracted, hyperacoustic in addition second order effect, as mechanical oscillation, emulsification, spread, smash, chemical effect etc. can quicken also that desire extracts that the diffusion of composition discharges and fully and solvent, be beneficial to extract.Compare with conventional extraction method, have extraction time short, productive rate is high, need not advantage such as heating, the flow process that can simplify the operation greatly, shorten extraction time, improve the output and the purity of product.
4, compound method advanced person
It is compound formulated that the present invention gathers multiple medium-height grass the effective elements of the medicine, taken into full account the characteristic of various medicinal materials, complex interactions mechanism between Chinese herbal medicine has been carried out rational simplification, desinsection scope according to different Chinese herbal medicines, by special ratios selected medicinal material has been carried out composite, thereby improved the desinsection scope of this insecticide greatly.And in prescription, added auxiliary materials such as sesamin, castor-oil plant as synergist, and the limonoid that extracts from oranges and tangerines etc. makes insects produce food refusal, also added the grass-leaved sweetflag that destroys the insect reproductive function, this has effectively strengthened the effect of this insecticide.
5, final products are dry powder
The final products of existing this type of technology are missible oil or solution, and this has brought very big trouble to storage and transportation, and the stability of this series products is also very low simultaneously, very easily decompose and go bad, thereby its drug effect is reduced greatly.Present technique is processed as the dry powder shape with the final products of insecticide in process of production, and this process has overcome the shortcoming of original technology, has improved the stability of product, has brought convenience also for simultaneously links such as preserving transportation.
This product has advantages such as easy degraded, low-residual, hypotoxicity, wide adaptability, good disinsection effect, thereby has avoided the pollution to environment of the generation of pest resistance to insecticide and traditional chemical agricultural chemicals effectively, and can improve the grade of agricultural product significantly.
The present invention will be further described below in conjunction with embodiment.

From Preliminary experiment results, this novel environment-friendly pesticide that we develop has following characteristics and effect:
1, production cost is low
The raw materials for production of this invention are common Chinese medicinal herbs, and medicinal material is of a great variety, the source is wide, price economy, and production process is simple to operate, the extraction efficiency height, and this has just determined that this production cost of products is low.
2, efficient, wide spectrum, applicability are wide
To the experimental result of various pests, the insecticidal effect of this environment-friendly pesticide is very remarkable from present.This insecticide to be form such as tagging, stomach kills, and larva, adult and the ovum thereof of insects such as cotton bollworm, blue or green worm, aphid, two spotted spider mite all had highly effective fragmentation effect.We use composite side's form (being the organic assembling of several wild plant active ingredients) to make it to replenish mutually, maximize favourable factors and minimize unfavourable ones, thereby have made this universal vegetable insecticide.It has overcome the shortcoming that traditional chemical agricultural insecticide performance is single, accommodation is narrow, and is much more superior than traditional agricultural chemicals to the fragmentation effect of various pests, is a kind of environment-friendly pesticide of efficient, wide spectrum.
Experimental result:
1, insecticidal effect experiment
We have carried out the insecticidal effect experiment with this insecticide to various pests such as cotton bollworm, blue or green worm, aphids, and result of the test shows this insecticide good disinsection effect, and is applied widely, and larva, adult and the ovum thereof of various pests all had stronger lethal effect.
Gather various insects (band plant stem-leaf) from the flowers and plants vegetables, with the fly spray test of in the laboratory, repeatedly dividing into groups of the soup of 1ppm concentration.
Be fragmentation effect experiment below to different insects:
| Concentration | Subjects | Kill rate | Last the time |
| ??1ppm | Blue or green worm | ????98％ | ????12min |
| ??1ppm | Aphid | ????95％ | ????15min |
| ??1ppm | Two spotted spider mite | ????90％ | ????21min |
Table 4-1 is to the fragmentation effect of different insects
2, at areal to a kind of insect, do the contrast experiment with conventional pesticides:
We are with the acephatemet in this insecticide and the traditional agricultural chemicals and kill the chrysanthemum ester and do the desinsection contrast
Test, the result is as shown in the table:
The insecticidal effect of table this environment-friendly pesticide of 4-2 and traditional chemical agricultural chemicals relatively
This environment-friendly pesticide has extensively, insecticidal effect efficiently, and this insecticide can overcome also that the conventional pesticides desinsection is single, the shortcoming of narrow application range in addition.For example: traditional agricultural chemicals acephatemet, kill the chrysanthemum ester and be difficult to obtain good insecticidal effect during two spotted spider mite in control.We are considering to make form more complicated, more effective composite side, so just can further enlarge the scope of application of insecticide; Improve constantly its lethality, further shorten the desinsection time, and in experiment, obtained initial achievements.
3, effectively prevent the pesticide resistance of insect
Because a large amount of uses of traditional chemical pesticide, they have produced very strong resistance to medicine characteristic already in pest body, if the pesticide resistance to insect is ignored, continue to use chemical pesticide, not only be difficult to receive good insecticidal effect, can cause stronger pesticide resistance on the contrary, insect is morphed, cause traditional chemical insecticide to be difficult to play a role, and can there be above-mentioned a series of problem in novel pesticide.Insect can not form pesticide resistance at short notice to the pure natural novel pesticide, and this also is that this insecticide is different from one of the most outstanding advantage of traditional insecticide.
In addition, this insecticide is owing to be the product of pure natural, and good with the amalgamation of nature, the long-term use generally can not developed immunity to drugs.So this novel environment-friendly pesticide is the first-selected insecticide under the current new agriculture theory.
4, lasting medicine, easily degraded, noresidue, toxicity are low
The tradition agricultural chemicals only has lethal effect to insect in the short period of time, then enters in the plant corpus thereupon or becomes scattered about occurring in nature, has both accumulated in wherein very easily people and animals being damaged, and destroys environment again, and insect is not had lethal effect.We adopt advanced production technology to handle medicine now, proper extension the stability of active ingredient, strengthened desinsection effectiveness.This environment-friendly pesticide can be kept long-term insecticidal effect from spraying certainly in one period.Although the lasting medicine of this insecticide, because this kind insecticide comes from nature, mechanism of degradation uniqueness, catabolite is pollution-free, so it all compares safety to natural environment and people and animals.Its why both lasting medicine and easily degraded, be since it only on the blade face of plant and the surface of fruit play lethal effect and can enrichment in plant corpus, the desinsection term of validity can progressively be decomposed later.This is to compare one of the most outstanding characteristics with traditional agricultural chemicals.
5, the Environmental security of insecticide is measured
This insecticide does not use any artificial chemical combination composition in process of production, and all raw materials all derive from natural.We have adopted advanced production technology, and effective component extracting from the pure natural Chinese herbal medicine fully is even the emulsifier that uses in emulsion process also is a pure natural.This insecticide stable in properties, not facile hydrolysis, photodissociation, not volatile, and toxicity is little, is easy to degraded, so in use do not pollute the environment.
6, toxicity test
Because the pure natural property of this insecticide, he and natural world amalgamation are good, to the outer other biological nonhazardous effect of getting rid of insects in the environment.We have done following experiment for test period toxicity: prepare the soup of variable concentrations such as 1ppm, 2ppm, 5ppm, 10ppm, 20ppm respectively, soup is sneaked in the biological food such as rat, silkworm, honeybee, fed continuously one month.Measure its half lethal dose, and compare, find that this product is the hypotoxicity agricultural chemicals with traditional agricultural chemicals,
Data are as follows:
| The agricultural chemicals name | LD 50(mg/kg) | The agricultural chemicals name | ??LD 50(mg/kg) |
| Acephatemet | 25 | Rotenone | ????1244 |
| Rogor | 350 | Matrine | ????5000 |
| Sumicidin | 451 | The chinaberry element | ????5000 |
| Hexachlorcyclohexane | 125 | This product | ????4000 |
The different agricultural chemicals of table 4-3 toxicity relatively
7, degradation property is measured
Degradation curve figure is as follows:
Through statistics, find that the degraded of agricultural chemicals on some direct acceptors is to use C=C to a large amount of experimental datas
0e
-ktMathematic(al) mode represent.The degradation speed that can be found this product by above chart is fast, and degraded is very thorough.So, use the agricultural product of this pesticide producing can reach present international quality inspection standard.In order to determine the result of degradation experiment, we test with white rabbit.Nursing is after five months continuously with the green grass of spraying insecticide, and white rabbit does not have bad reaction, by chemically examining its ight soil, blood, proves that noxious material does not exceed standard in the white rabbit body, and growing state is good.This shows that this insecticide degradation property is superior, can not pollute environment and agricultural product, is a kind of ideal green insecticide.
By above each test as can be seen, this environment-friendly pesticide has been broken through the constraint of traditional extraction technique, adopts brand-new extraction process processing formulated.It utilizes the big characteristics of wild plant active ingredient otherness, has overcome the single and similar shortcoming of traditional chemical pesticide structure, has prevented the formation of pest resistance to insecticide effectively, can keep efficient and long-term insecticidal effect.This in addition environment-friendly pesticide derives from nature fully, and natural environment is had amalgamation preferably, and easily degraded, noresidue can not bring any negative effect to people and animals and environment behind the desinsection.
