Description
Technical field
The invention belongs to preparation technique of pesticide fields, and in particular to, specially a kind of plant pesticide and preparation method thereof.
Background technology
Prevention agricultural pests all use chemical insecticide mostly at present, and with the improvement of people's living standards, people couple
Agricultural product quality requires to increase, and not only to eat, but also to eat healthy.The pesticide residue that high poison chemical pesticide is caused is asked
Topic has become the hot spot of social concerns.High-toxic pesticide is the core and key for influencing agricultural product quality and safety, not only influences agriculture
Product quality directly endangers the health of the people, has an effect on increasing peasant income.Since the toxicity of high-toxic pesticide is big, in the past
The event of person poultry poisoning is caused to happen occasionally.Influence to women and children is very big, and there are many children that teratogenesis is disabled.In addition, with
It countries in the world to be increasingly enhanced the protective awareness of environment for human survival and natural, ecological, high poison high residue insecticide will be further
It is restricted.The unreasonable use of pesticide constitutes a threat to the quality safety of agricultural product, therefore, it is particularly high to reduce Pesticide use
Malicious Pesticide use to improving agricultural product quality and the market competitiveness, promotes China's agricultural sustainable development, ensures broad masses of the people
Life security and build a harmonious society and suffer from very great meaning.Simultaneously as chemical pesticide is easy to cause pest
Drug resistance, in order to which control effect is continuously increased using dose, has not only murdered many natural enemies and beneficial organism, also polluted me
Living environment of depending on for existence.It, will to the Detecting Pesticide in agricultural product with the increasingly attention that Environmental is protected
Can be further stringent, therefore, greatly develop the direction that non-toxic and non-pollution high-efficiency plant source pesticide is Agrochemicals from now on.
Invention content
It is an object of the invention to overcome prior art defect, a kind of biology insecticide is provided.
Another object of the present invention is to provide a kind of biology method for producing insecticide.
Technical scheme is as follows：
A kind of plant pesticide , You Aralia woods and Chinese ash tree raw material are made；
Bulk pharmaceutical chemicals are placed in reaction kettle, by solid-liquid weight ratio 1：4 ratio injection water；It is heated to electric heating steam generator
80 degrees Celsius after 4 hours, the separation of liquid and the dregs of a decoction is carried out into centrifuge；It is prepared after liquid is concentrated.
Further, Shang Shu Aralia woods are one of arbitrary or two or more mixing in its leaf, tree root, bark, flower, fruit,
The Chinese ash tree is its leaf, branch, bark, flower, fruit are one of arbitrary or two or more mixing.
Further, Shang Shu Aralia woods and the ratio of Chinese ash tree are：1 : 3.
Further, above-mentioned plant pesticide is as the application in the prevention and control of plant diseases, pest control.
Aralia wood and Chinese ash tree bulk pharmaceutical chemicals are placed in reaction kettle by a kind of plant pesticide method for producing insecticide ,, by solid-liquid
Weight ratio 1：4 ratio injection water；80 degrees Celsius are heated to after 4 hours with electric heating steam generator, are carried out into centrifuge
The separation of liquid and the dregs of a decoction；Liquid is concentrated to being made after original volume 1/3.
Pharmacology of the present invention is as follows：Chinese ash is being taken as agriculture in early days because its stem, leaf, flower and fruit etc. all have unique smell
Medicine is used to prevent pest and disease damage.More and more to the research of the effect of pest currently with Chinese ash extract, extract is to noctuid
Prodenia litura and bollworm adult in section have attracting action, and have smoked dead effect to some storage pests, such as sitophilus zea-mais,
There is the inhibiting effect to disease simultaneously；Aralia wood has a variety of medical values, there is potent sterilization, anti-inflammatory, antiviral
The effects that.
The beneficial effects of the invention are as follows：
1st, effectively inhibit the common fruits and vegetables insect pests such as cabbage caterpillar, aphid, diamondback moth, prodenia litura, red spider, smaller green leaf hopper, once
Eradicative rate is up to more than 80%；
2nd, there is certain control effect to common diseases of garden stuff such as Cabbage Leaf Spot etc.；
3rd, liquid sheet is as medicine based on herbs, and nonhazardous, noresidue is environmentally protective nuisanceless, will not lead to environmental pollution；
4th, it is extensive that raw material sources are prepared, inexpensively；
5th, it is of low cost to produce extensively, and environmentally friendly.
Specific embodiment
Technical scheme of the present invention is further detailed and described below by way of specific embodiment.
(1) by the leaf of air-dried Aralia woods, tree root, bark, flower, fruit and the leaf of air-dried Chinese ash tree, branch, tree
Skin, flower, fruit（Weight ratio 1:3）Bulk pharmaceutical chemicals are mixed into after being crushed to 2 millimeters；(2) bulk pharmaceutical chemicals are placed in reaction kettle, by solid-liquid
Weight ratio 1：4 ratio injection water；（3）With electric heating steam generator be heated to 80 degrees Celsius enter after 4 hours centrifuge into
The separation of row liquid and the dregs of a decoction；(4) by liquid merging concentration tank be concentrated into original volume 1/3 be made biology insecticide bottling it is standby
With.
Specific embodiment 1：The experiment of insecticide control cauliflower aphid, cabbage caterpillar made from above-described embodiment.
