Abstract
A liquid insecticide for aphis a mite is prepared from more than 10 Chinese-medicinal plants including Kan-sui root, sixangular drsosma rhizome, giraldi daphne bark, stemona root, etc. through twice immersing to extract the mixed liquid, concentrating and adding assistants. Its advantages are strong power to kill pests, no environmental pollution, and simple preparing process.
Description
The invention belongs to insecticide and preparation method thereof, relate in particular to a kind of liquid insecticide as agricultural chemical prepared from natural plant and preparation method thereof.
Being used to prevent and treat the agricultural chemicals of diseases and pests of agronomic crop at present, mostly is chemicals.Introduce according to second edition in " Chinese patent newspaper " on June 2nd, 1993 " development Overview of pesticide industry and patent situation " a literary composition: nineteen ninety China's Pesticidal products account for the second place of the world, produce 156 kinds of pesticide species, wherein insecticide is 59 kinds, 9 kinds of miticides, 3 kinds of fumigant, 7 kinds of rodenticides, 39 kinds in bactericide, 33 kinds of weed killer herbicides, 6 kinds of plant growth regulator.These agricultural chemicals overwhelming majority belong to chemicals, chemical agents such as the Methomyl that uses as the cotton grower, decis, beta-cypermethrin, nuvacron, Rogor, phoxim, these chemical pesticides make damage by disease and insect have pesticide resistance for a long time, when spraying insecticide, the concentration of agricultural chemicals rises year by year, and the thing followed is seriously to have polluted environment, water resource and crops itself, this has not only destroyed the ecological balance, has also endangered people and animals' health and safety simultaneously.According to United Nations Environment Programme's statistics, the whole world has 2,000,000 people that acute pesticide poisoning takes place every year, wherein has 40,000 people to die.Moreover, also because the pesticide residues thing severe overweight in the food causes people to cause illnesss such as cancer and neurotoxic.Along with high development of social economy, people's life requires generally to improve, the enhancing of self-protection and self-health perception, and people are seeking a kind of pollution-free, insecticide without environmental pollution.
The purpose of this invention is to provide liquid insecticide as agricultural chemical prepared from natural plant of a kind of nuisanceless, pollution-free, no residual hazard and preparation method thereof.
The raw material of liquid insecticide as agricultural chemical prepared of the present invention comprises following component (consumption is a weight portion):
Host: wild cigarette 5-20 part root of gansui 1-10 part
Chinese honey locust 2-8 part Dysosma versipellis 4-15 part
Big root of langdu 5-15 part chinaberry 5-15 part
Tuber of stemona 2-12 part chenopodium ambrosiodies 2-10 part
Corter pseudolaricis 5-10 part girald daphne bark 5-15 part
Kuh-seng 1-15 part is tuber of pinellia 1-15 part early
Auxiliary agent: agricultural emulsifier 2-8 part penetrating agent JFC 2-6 part
Ethylene glycol 1-4 part fatty alcohol JFC 1-5 part
Turpentine oil 1-4 part neopelex 1-5 part
Anti-reinforcing agent 10-20 part disappears
The above-mentioned anti-reinforcing agent that disappears is made (consumption is a weight portion) by following component:
Vigorous diligent 10-25 part Zanthoxylum simulans 5-10 part of returning
The little sharp green pepper 10-25 part of rhizome of Chinese monkshood 10-25 part
Fructus gleditsiae 1-5 part datura 5-20 part
5 parts of fatty acid alcohols
Host also can add false spiraea 1-12 part, foretells mustard 1-5 part.
Preparation method's concrete steps of the present invention are as follows:
(1) the various crude drugs of liquid insecticide as agricultural chemical prepared raw material are carried out selected, reject damage by worms, go mouldy, impurity etc., the medicinal material of choosing cut into slices or be ground into 20-40 order particle;
(2) taking by weighing the selected various medicinal materials of step (1) by above-mentioned aqueous solution of insecticide raw material weight proportioning is placed in 20-50 ℃ the acid solution and soaked 6-10 hour, the dregs of a decoction after the filtration use the same method and carry out secondary immersion 8-10 hour, secondary filter, clarification, twice extraction soak merged, and the ratio that is concentrated to medicinal material and solvent is 10:2～4; Adding 1% methyl preservative then, during greater than 2-5, be between the 3-7 to pH as the pH of acid original liquid with cash material tone pitch;
(3) with selectedly good suddenly rein in back, Zanthoxylum simulans, the rhizome of Chinese monkshood, little sharp green pepper, fructus gleditsiae, six kinds of medicinal materials of datura, put into the doubly industrial alcohol of molten amount of 10-15, in 20-30 ℃ airtight molten device, soaked 72-96 hour, filter then, the clarification back adds 5% fatty acid alcohol, promptly becomes the anti-reinforcing agent that disappears;
(4) get the anti-agent 10-20 part that disappears that step (3) obtains and join in the original liquid that step (2) obtains, stir, be liquid insecticide as agricultural chemical prepared.
The present invention compared with prior art has following advantage:
(1) this insecticide utilizes multiple wild plant and cultivated plant to be raw material, and the active ingredient that extracts the intoxicating effect is as red root cash, coptis cash, chelerythrine cash, Chinese ephedra cash, faenum graecum cash, saponin, wartwort toxin, kaempferol, Andromedotoxin, rhizome of Chinese monkshood cash, inferior rhizome of Chinese monkshood bar, tuber of stemona cash, cigarette cash, kuh-seng cash etc.These have intoxicating action activity material, can suppress the breathing of insect by tagging, the adhering to of acetyl courage cash acceptor, and make the insect nervous system impaired or adhere to calcium channel on the sarcoplasmic reticulum, muscle is poisoned rapidly cause death.The metabolic function that can destroy insect by stomach toxicity causes death.
(2) broad spectrum activity: to the insect of economic crops such as cereal crops, cotton, pawl fruit, vegetables, tealeaves, citrus, as aphid, acarid, peach fruit borer, cabbage caterpillar, cotton bollworm, smaller green leaf hopper different fragmentation effects is arranged all, and to the fusarium wilts of cotton, vegetables, downy mildew, early late blight, anthracnose all have certain control efficiency.
(3) three-waste free discharge in process of production can not form pollution to ecotope.
(4) to no residual hazard effect after the crops dispenser, because of the photosynthesis by crop carries out decomposition and inversion, the toxicity Lock-out.
(5) medicinal raw material is except that utilizing wild plant resource, but all establishing in large scale and cultivations of most medicinal materials, so both adjusted agricultural structure, increased peasant's income again, guaranteed the source of suitability for industrialized production public nuisance-free agricultural chemicals raw material simultaneously, and established certain basis for the ecological organic agricultural replaces the conversion of inorganic chemistry agricultural to solve pollution-free food.
(6) preparation technology is simple, cost is low, efficient is high, raw material sources are extensive, is easy to promote the use of.
(7) these goods not only have desinsection, sterilization functions, and crops are also had the facilitating effects of expediting the emergence of.
