Another object of the present invention is to provide a kind of preparation method of composite plant source pesticide, it is characterized in that: comprise the following steps:
(1) take without going mouldy, the kuh-seng without rotten, black false hellebore, the tuber of stemona, China tree, Rhododendron molle and tarragon, clean up, standby;
(2) step individual component is (1) added respectively in the cold water of 8 times of weight and decoct;
(3) the filtering dregs of a decoction, the concentrated liquid extract that forms of the independent low temperature of each liquid;
(4) in proportion each liquid extract is mixed, form mother liquor after adding water;
(5) mother liquor (4) of step is further processed to then in storage tank standing 72 hours through colloid mill and homogenizer;
(6) the supernatant of getting after standing adds auxiliary agent and synergist in proportion, after then stirring in Chinese medicine emulsification pot, makes finished product.
The process for preparation of described auxiliary agent is:
Use phase solvent dilution turpentine oil, continue to add emulsifier, bleeding agent, ethanol, stir.
Another object of the present invention is to provide a kind of using method of composite plant source pesticide, it is characterized in that: in finished product, add the water dilution of 800~3000 times, then spray.
Advantage of the present invention and good effect are:
In the present invention, by metering, take kuh-seng, black false hellebore, the tuber of stemona, tobacco leaf, Rhododendron molle and tarragon, after screening, boiling are extracted, are purified, make the extract that contains each component active ingredient, then will after mother liquor and additive compound, make finished product, this finished product is tested through many-side, without bad penetrating odor, drug residue free, people and animals, agricultural product, air, soil are not all had to poisoning, possess desinsection, antibacterial effect, be applicable to the ground such as land for growing field crops, booth, nursery, golf course, tea place and forestry greening and use.
Embodiment
Below in conjunction with embodiment, the present invention is further described, and following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
A composite plant source pesticide, innovation of the present invention is: comprise mother liquor and auxiliary agent, the raw material of described mother liquor comprises the following component of mixing by weight percentage:
Figure BDA0000422825130000041
Described auxiliary agent comprises emulsifier, bleeding agent, 95% ethanol, phase solvent and turpentine oil, and the percentage by weight that each component accounts for mother liquor is respectively 15%, 13%, 10%, 12% and 4%.Described emulsifier is the mixture of sheep oil, fatty alcohol-polyoxyethylene ether, castor oil polyoxyethylene ether and absolute ethyl alcohol, and the weight ratio of each component is 3:3:2:2.Described bleeding agent is a kind of in dimethyl sulfoxide (DMSO), azone or thiophene ketone.Described phase solvent is cyclohexanone.Described mother liquor and auxiliary agent add synergist after mixing, and this synergist is the Affirm (Merck Co.) of mother liquor weight 2~3 ‰, at least one in 9 ‰ Avermectin.
The preparation method of above-mentioned composite plant source pesticide comprises the following steps:
(2) get without going mouldy, the kuh-seng without rotten, black false hellebore, the tuber of stemona, China tree, Rhododendron molle and tarragon, clean up, standby;
(2) step individual component is (1) added respectively in the cold water of 8 times of weight and decoct, 120 ℃ of temperature, decoct 2 hours;
(3) the filtering dregs of a decoction, the concentrated liquid extract that forms of the independent low temperature of each liquid;
(4) in proportion each liquid extract is mixed, form mother liquor after adding water;
(5) mother liquor (4) of step is further processed to then in storage tank standing 72 hours through colloid mill and homogenizer;
(6) the supernatant of getting after standing adds auxiliary agent and synergist in proportion, after then stirring in Chinese medicine emulsification pot, makes finished product.
The process for preparation of described auxiliary agent is:
Use phase solvent dilution turpentine oil, continue to add emulsifier, bleeding agent, ethanol, stir.
In the present invention, in kuh-seng, extract oxymatrine, in black false hellebore, extract jervine, in the tuber of stemona, extract stemonine, in China tree, extract margosine, in Rhododendron molle, extract Andromedotoxin and Chinese photinia element, from tarragon, extract Blumea oil, each active ingredient cooperatively interacts, by auxiliary agents such as emulsifier, form liquid, wherein utilize all ginsengs (ginseng, Radix Codonopsis, the root of straight ladybell, radix scrophulariae, kuh-seng, the red sage root) pungent (root of Chinese wild ginger) Chinese herbaceous peony (radix paeoniae rubrathe root of herbaceous peony) black false hellebore of betraing in the traditional eighteen incompatibilities theory of Chinese medicine, be to mutually promote after oxymatrine and jervine combination, increase insecticidal activity.
During use, by the multiple dilution by weight of liquid water, in the prevention stage, can be diluted to 3000 times, in the stage occurred frequently, can be diluted to 800 times, carry out complete stool sprinkling, do not mix with strong alkaline substance, the morning, 10 left and right medications were best, avoided rainwater, and it will be tagged, stomach kills and combines, after spraying, make insect death by suffocation, before medication, this product is fully shaken up, inside have a small amount of sediment not affect desinsection quality, be applicable to land for growing field crops, booth, flowers, golf course, tea place, forestry greenery patches etc., nontoxic to people and animals, can contaminated air, environment, soil etc.
Each component adopts flooding to carry out effective component extracting, avoided water boiling and precipitation with ethanol method by nutriment precipitations such as polysaccharide, protein, by the effect of bleeding agent, these nutrients mass-energy rapid osmotic enter in plant cell, and insecticide sterilization component also can rapid osmotic, wherein dimethyl sulfoxide (DMSO) effect is better, but cost is low, azone and thiophene ketone better effects if, but cost is higher.
95% ethanol has played preservation, can make drug effect keep the longer time.Emulsifier makes liquid more even.Turpentine oil increases the adhesive force of liquid.
