Description

A kind of agrichemical without enviromental pollution for plant and preparation method thereof

The present invention relates to a kind of agrichemical without enviromental pollution for plant and preparation method thereof, is raw material with common plant specifically, by extracting the plant pesticide that its active ingredient prepares.

Chemical pesticide was once cooked the increasing both production and income of agricultural and was appeared huge contribution, now also still in occupation of leading position, but in the use of nearly half a century, its all drawback reveals gradually, is in particular in: the pollution to ecotope destroys serious day by day; The beastly poisoning of people happens occasionally; The pesticide resistance of insect strengthens, and dosage strengthens, and production cost rises year by year.Along with the growing interest of people to environmental protection and self health, people need safe, efficient, non-harmful biopesticide to substitute the stronger chemical pesticide of toxic and side effect that uses at present urgently.According to investigations, domestic most plant pesticides mainly are based on nicotine, seal chinaberry, trifoliate jewelvine and various medicinal herb components, and are that the public nuisance-free agricultural chemicals kind of raw material is comparatively rare with common plant.

The object of the present invention is to provide a kind of wide spectrum, efficient, safety, economy, non-harmful plant pesticide and compound method thereof.

Concrete technical scheme of the present invention is, after being the combination of raw material reasonable compatibility with cigarette broken (tobacco powder, tobacco stem, offal etc.), China tree, big tealeaves, the frequently seen plants such as numb leaf, pieris, sweet-scented oleander, cacumen biotae of combing, through pulverizing, lixiviate, filtration, conventional method such as concentrate and be prepared from.

Its raw material of agrichemical without enviromental pollution for plant of the present invention is formed (weight portion):

Broken 10～15 China trees of cigarette (seed, leaf, skin, root) 10～30

Pieris 5～10 big tealeaves 10～20

The numb leaf 5～15 of Chinese tallowtree leaf 5～20 combs

Cacumen biotae 4～6 sweet-scented oleanders 5～10

Azalea pontica 2～3 tree-of-heavens (leaf, skin) 7～12

Tea seed cake 1～3 wild pepper (seed, leaf, skin) 2～5

Capsicum 3～5 garlics 2～5

The preparation method of agrichemical without enviromental pollution for plant of the present invention is:

1. pulverize after the cigarette of aforementioned proportion is broken, the China tree removal of impurities, industrial alcohol with 95%, lixiviate is 12～16 hours between 35 ℃～45 ℃, squeeze and filter, the dregs of a decoction repeat lixiviate once again, and twice leaching liquor is mixed, and are evaporated to 1/3～1/5 of medicinal powder weight, alcohol reclaims, and obtains the oily liquids of thickness;

2. respectively pieris, big tealeaves, the numb leaf of combing, sweet-scented oleander, cacumen biotae, tree-of-heaven leaf, Chinese tallowtree leaf, Azalea pontica, wild pepper are chopped into 2～5 millimeters segment, tea seed cake powder is broken into 20 purpose meal, mix in proportion, put into container, soak with clear water and to quench 8～10 hours, the clear water addition is as the criterion to cover medicine, the middle stirring once.Be warming up to 100 ℃ then, keep slight boiling condition half an hour, squeeze and filter adds water boil half an hour again to the dregs of a decoction, filters.Twice filtered fluid mixes, and vacuum concentration is to original 1/40～1/50;

3. capsicum and garlic are squeezed respectively and obtain capsicum water and garlic juice;

4. will mix through each drug component that above-mentioned steps obtains, regulating the pH value is 5.5～6.5, add the castor oil that accounts for medicament gross weight 3～5%, 8～10% farm chemical emulgent, 1～3% Sodium Benzoate, 1～3% dodecyl sodium sulfate, 0.1% bubble enemy again, in high-speed mixer, stirred 60～90 minutes, and be agrichemical without enviromental pollution for plant of the present invention.

In the agrichemical without enviromental pollution for plant of the present invention, main active ingredient comprises 1. alkaloids: nicotine, the climing rattan alkali of Hu, the 2. glucoside of numb alkali of combing: oleandrin, tea saponin, the 3. plain class of arbor-vitae glucoside: margosine, saponin, ricin, asebotin, loose plum bitter principle, capsaicine, allicin, Chinese azalea extract III be the alkene class 4.: camphene, two the eleventh of the twelve Earthly Branches alkene, thujene be ketone 5.: absinthol is the ester class 6.: amarolide, tree-of-heaven caprylolactone C be amine 7.: pepper amine is other class 8.: ricin, tannin, essential oil, phenols etc.

Agrichemical without enviromental pollution for plant of the present invention has the following advantages:

1. be raw material with common plant, raw material sources are wide, and are cheap, and production cost is low, and production technology is simple, are fit to various large-scale production;

2. have anesthesia concurrently, tag, multi-efficiencies such as stomach toxicity, neural poisoning, killing ability is strong, speed is fast, medication after one day insect population go down rate more than 75%, insect population goes down rate more than 95% two days later;

3. the desinsection scope is wide, our experiments show that, to lepidoptera pest such as cabbage caterpillar, cotton bollworm, mythimna separata, corn borer, sesame snout moth's larva, diamond-back moth, leaf miner, prodenia litura, three-spotted plusia, beet armyworm, sesame hawkmoth, soybean noctuid, tomato moth, apple skin worm; Coleopteran pest such as tooth worm, chafer, longicorn beetle, broad bean weevil, pea weevil, adzuki bean weevil; Homoptera pest such as aphid, wood louse, aleyrodid, yellow big lice, scale insect, oriental fruit moth; Diptera pest such as liriomyza bryoniae, Liriomyza; Thrips insect such as thrips etc. all have good integrated control effect, and to two spotted spider mite, looper and various worm, and soil insect such as grub, mole cricket, ant, wireworm, cutworm and worm's ovum have very strong killing effect;

4. stronger sterilization functions is arranged, downy mildew, vermicelli disease, defoliation, rust staining disease, rice blast etc. are had desirable control efficiency;

5. dosage is few, and insect is difficult to develop immunity to drugs;

6. the no three wastes produce in the production process, and drug ingedient can decompose in nature fully, can be particularly useful for the production of organic food, pollution-free food and pollution-free food in a plurality of fields extensive uses such as agricultural, forestry, animal husbandry.
