Abstract

A kind of insecticide for tealeaves includes following component：Radix sophorae, Celastrus angulatus root, polygonum flaccidum, print kerria seeds, sodium alkyl benzene sulfonate, butyl glycidyl ether, alkyl carbonate, ascorbic acid, plant ash.The invention also discloses a kind of method for producing insecticide for tealeaves：By radix sophorae, Celastrus angulatus root, polygonum flaccidum, print kerria seeds crushes after cleaning, it is heated to reflux again by ethanol as molten, after effective component extracting, mixed again with sodium alkyl benzene sulfonate, butyl glycidyl ether, alkyl carbonate, ascorbic acid and plant ash, and stir and obtain insecticide for tealeaves.By around desinsection dilution agent 200 500 times of stalks for being sprayed on tealeaves, leaf and roots during use.The insecticide can quickly and efficiently kill false eye leafhopper, Aleurocanthus spiniferus, tea aphid, pink tea rust mite in tealeaves, have the advantages that again nontoxic pollution-free.

Description

Insecticide for tealeaves and its production and use
Technical field
The present invention relates to a kind of insecticide and its production and use, more particularly to a kind of insecticide for tealeaves and Preparation method and use, belong to pesticide processing field.
Background technology
China is Chan Cha big countries, and cultivated area occupies first in the world, and tea growers are for convenience and quick, mostly using desinsection Agent, insecticide are mainly used for preventing a kind of agricultural chemicals of agricultural pests.At present, wide in variety, the yield of product occupy insecticide first Position and a most widely used insecticides be organophosphorus insecticides, this insecticides be typically be made of chemical synthesis process, Although it has the advantages of desinsection is quick, persticide residue is big, and the food that this insecticides was applied in long-term consumption can make one Body produces chronic toxicity, and the living environment of the mankind is constituted a threat to.In recent years, the Pesticide Residue of tealeaves has caused people's Extensive concern, the residues of pesticides of tealeaves are exceeded to be primarily due to using caused by high poison persistent pesticide.
But botanical pesticide is a kind of free from environmental pollution, the biological pesticide of public hazards is not produced, and botanical pesticide is to utilize plant Some positions of thing extract its effective ingredient the agricultural chemicals with desinsection or bactericidal action are made, not welding, and residual is few, makes It is low with cost.Production to non-polluted tea is of great advantage, there is vast potential for future development.
Kuh-seng is cassia leguminous plant, first recorded in《Sheng Nong's herbal classic》, at least have more than 2000 year according to literature record and go through History, it is one of time-honored conventional medicament in China.Matrine is the biology made of the root of Chinese herbal medicine kuh-seng, fruit extraction Alkali preparation, it is alkaloid, generally Banlangen, its main component have matrine, sophocarpine, N-Oxysophocarpine, Sophoridine etc. A variety of alkaloids, with matrine, oxymatrine concentration highest.Matrine has to insect tags and stomach poison function, is a plant Material resource agricultural chemicals, its insecticidal mechanism is to benumb insect nerve center so that polypide protein coagulating, air-hole blockage, it is last because It is choked to death, matrine easily decomposes, basic noresidue.
But single Kushen ' is limited to the lethality of worm, in order to provide the effect to insecticide, the present invention puies forward one kind Plant insecticide containing matrine, it can quickly and efficiently kill various insects, have again nontoxic pollution-free etc. excellent Point.
The content of the invention
The present invention is to overcome the shortcomings that single Kushen ' is to the lethality deficiency of worm, there is provided a kind of containing matrine For the insecticide of tealeaves, it is adapted to the preventing and treating of tea lesser leafhopper during tea picking, can effectively reduces collecting period chemical pesticide Usage amount, reduce residues of pesticides, it is more green.
To achieve these goals, the invention provides a kind of insecticide for tealeaves, the insecticide to include with weight The following component of number meter：
Radix sophorae 10-20 parts；
Celastrus angulatus root 10-20 parts；
Polygonum flaccidum 5-10 parts；
Print the sub- 10-20 parts of kerria seeds；
Sodium alkyl benzene sulfonate 2-5 parts；
Butyl glycidyl ether 2-5 parts；
Alkyl carbonate 2-5 parts；
Ascorbic acid 2-3 parts；
Plant ash 2-5 parts.
Preferably, the insecticide includes the following component in terms of parts by weight：
15 parts of radix sophorae；
15 parts of Celastrus angulatus root；
8 parts of polygonum flaccidum；
Print 15 parts of kerria seeds；
3 parts of sodium alkyl benzene sulfonate；
3 parts of butyl glycidyl ether；
3 parts of alkyl carbonate；
2.5 parts of ascorbic acid；
3 parts of plant ash.
Present invention also offers a kind of method for producing insecticide for tealeaves, the preparation method comprises the following steps：
(1) radix sophorae, Celastrus angulatus root, polygonum flaccidum are chosen, and print kerria's seeds is eluted with water and crushed；
(2) raw material sieving will be crushed, powder is collected and is mixed evenly to obtain pulverulent mixture；
Using pulverulent mixture by the use of the ethanol that concentration is more than 90% as solvent in 60-80 DEG C of laser heating backflow 2-4 h；
(4) by reaction solution by being filtered by vacuum, collection filtrate,；
(5) stand, after allowing ethanol to volatilize, obtain active components of plants extract；
(6) finally by active components of plants extract and sodium alkyl benzene sulfonate, butyl glycidyl ether, alkyl carbonate, anti-bad Hematic acid and plant ash mixing, stir, that is, obtain the insecticide for tealeaves containing matrine.
Present invention also offers a kind of insecticide for tealeaves as false eye leafhopper, black thorn powder in preventing and treating tealeaves Lice, the application of tea aphid, pink tea rust mite.
The beneficial effects of the present invention are：The insecticide primary raw material for tealeaves of the present invention is radix sophorae, Celastrus angulatus Root, polygonum flaccidum, print kerria seeds, material composition is nontoxic, safety；The insecticidal active ingredients such as its matrine, Celastrus angulatus, eugenol Complement each other, strengthen insecticidal effect, in addition also contain vegetation ash component, plant ash energy effectively preventing fly maggot, fragrant-flowered garlic maggot etc. Subterranean pest-insect, moreover it is possible to supplement potassium element to tealeaves.
