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 kind of composite plant source pesticide, innovation of the present invention is: comprise mother liquor and auxiliary agent, and the raw material of described mother liquor comprises the following component mixed by weight percentage:
Described auxiliary agent comprise emulsifier, bleeding agent, 95% ethanol, phase solvent and turpentine oil, 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 the one in dimethyl sulfoxide (DMSO), azone or thiophene ketone.Described phase solvent is cyclohexanone.Described mother liquor and auxiliary agent mixing after add synergist, this synergist be mother liquor weight 2 ~ 3 ‰ Affirm (Merck Co.), 9 ‰ Avermectin at least one.
The preparation method of above-mentioned composite plant source pesticide comprises the following steps:
(2) get without the kuh-seng gone mouldy, nothing is rotten, black false hellebore, the tuber of stemona, China tree, Rhododendron molle and tarragon, clean up, for subsequent use;
(2) step individual component (1) added respectively in the cold water of 8 times of weight and decoct, temperature 120 DEG C, decocts 2 hours;
(3) the filtering dregs of a decoction, the independent low temperature of each liquid is concentrated forms liquid extract;
(4) in proportion each liquid extract is mixed, after adding water, form mother liquor;
(5) step mother liquor is (4) processed further through colloid mill and homogenizer, then in storage tank, leave standstill 72 hours;
(6) the supernatant got after leaving standstill adds auxiliary agent and synergist in proportion, obtained finished product after then stirring in Chinese medicine emulsification pot.
The process for preparation of described auxiliary agent is:
Use phase solvent dilution turpentine oil, continue to add emulsifier, bleeding agent, ethanol, stir.
In kuh-seng, oxymatrine is extracted in the present invention, jervine is extracted in black false hellebore, stemonine is extracted in the tuber of stemona, margosine is extracted in China tree, Andromedotoxin and Chinese photinia element is extracted in Rhododendron molle, Blumea oil is extracted from tarragon, each active ingredient cooperatively interacts, liquid is formed by auxiliary agents such as emulsifier, all ginseng (ginsengs in the eighteen incompatibilities theory wherein utilizing Chinese medicine traditional, 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, namely mutually promote after oxymatrine and jervine combination, increase insecticidal activity.
During use, by liquid use water multiple dilutions by weight, 3000 times can be diluted in the prevention stage, 800 times can be diluted in the stage occurred frequently, carry out complete stool sprinkling, do not mix with strong alkaline substance, about 10 medications in the morning are best, avoid rainwater, it will be tagged, stomach kills and combine, make suffocate pests dead after spraying, 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 not contaminated air, environment, soil etc.
Each component adopts flooding to carry out effective component extracting, avoid water boiling and precipitation with ethanol method the nutriment such as polysaccharide, protein is precipitated, 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.
The ethanol of 95% serves preservation, can make the time that drug effect keeps longer.Emulsifier make liquid evenly.Turpentine oil increases the adhesive force of liquid.
