Abstract
The present invention relates to Angulatin emulsion oil which is a natural plant pesticide. Angulatin as a main disinfestation component is an active substance extracted from the root bark of celastrus angulatus and has the molecular formula of C34H46O13. The Angulatin emulsion oil is prepared by that the Angulatin, emulsifying agents, penetrating agents and organic solvents are proportionally mixed at the room temperature and are stirred to a full dissolving state. The emulsion oil has the advantages of simple preparation method, low cost, good disinsection effect, safe production, no three wastes, no pollution and environmental protection, and has the obvious small lethality to native predators and the low toxicity to warm-blooded animals.
Description
The invention belongs to a kind of high-efficiency low-toxicity, nuisance-free plant matter insecticide, particularly a kind of insecticide of root bark of celastrus angulatus extraction of substance---emulsion oil of Angulatin.
Modern age, being extensive use of of organic insecticide alleviated the harm of damage by disease and insect to crops widely, protected agricultural production.But along with a large amount of uses of agricultural chemicals, the increase of insect tolerance, natural enemy minimizing, environmental pollution, the ecological balance are destroyed, sometimes even cause the person poultry poisoning.Over past ten years, broad research is extracted bioactivator from natural products both at home and abroad, purifies through separating, and measures molecular structure, as the template of synthetic novel pesticide.As pyrethroid, clam worm poison derivative, margosine, fennel artemisin etc.Though above insecticide good disinsection effect, cost is higher, and the cultivation area is subject to certain restrictions.CN1081570A discloses a kind of Celastrus angulatus insecticidal anti-feedant.This insecticide extraction of substance consumption is big, and cost is higher relatively, and insecticidal effect is not best.
Purpose of the present invention just provides a kind of good disinsection effect, and obviously less to natural enemy lethality, extremely low to the person poultry toxicity, with low cost emulsion oil of Angulatin.
A kind of natural plants matter insecticide emulsion oil of Angulatin contains root bark of celastrus angulatus extract, emulsifier, bleeding agent, organic solvent, and its percentage composition is: root bark of celastrus angulatus extract 5-20, emulsifier 5-20, bleeding agent 5-15, organic solvent 60-85.
Extractions such as the lipophilicity organic solvent ethyl acetate of the root bark of celastrus angulatus extract among the present invention, chloroform, benzene, toluene, the root bark of celastrus angulatus total extract that after concentrating, obtains, effective ingredient is Celangulin (Angulatin), wherein representative composition Celangulin A, and molecular formula is C34H48O13.Celangulin has very strong food refusal, repellent, stomach toxicity, anesthesia and bactericidal action, and is extremely low to warm blooded animal toxicity.
The said emulsifier of the present invention is the alkylphenol polyoxyethylene non-ionic surface active agent, has performance acidproof, anti-hard water, has solubilization concurrently.The best is Zhong Xin phenol polyethenoxy ether or OPEO.
The said bleeding agent of the present invention is dimethyl sulfoxide (DMSO) or dimethyl formamide, and it has very strong penetration power to the shell of insect.
Organic solvent of the present invention can be chosen industrial crude benzol wantonly, and wherein aromatic hydrocarbon is effective insecticidal agent, bactericide.Select toluene or dimethylbenzene for use.
Manufacture method of the present invention is as follows:
1, gets the raw material root bark of celastrus angulatus, clean, dry, pulverize, add ethyl acetate or chloroform or benzene and extract the Celangulin active principle.
2, root bark of celastrus angulatus extract, emulsifier, bleeding agent and organic solvent at room temperature mixed in proportion, stir to molten entirely.
The present invention has the following advantages: (1) Main Ingredients and Appearance is the high Celangulin of biologically active, good disinsection effect.Wheat aphid, vegetable aphid, cabbage caterpillar control efficiency are respectively: 86-95%, 80.4-87.9%, 90.5-95.1%; (2) drug resource is abundant, and production technology is simple, and cost is low; (3) strong to insect poisoning power, but extremely low to warm blooded animal toxicity, obviously less to natural enemy lethality, the favourable protection ecological balance; (4) production safety, the no three wastes, pollution-free, favorable environment protection.
Embodiment 1, the emulsion oil of Angulatin percentage composition:
Root bark of celastrus angulatus extract 8, Zhong Xin phenol polyethenoxy ether 10, dimethyl sulfoxide (DMSO) 3, toluene 79%.
Above-mentioned substance is mixed in proportion, at room temperature be stirred to molten entirely, emulsion oil of Angulatin.
1, get the emulsion oil of Angulatin for preparing, dilute 1000,2000,3000 times,
2, commercially available 40% flolimat, 10% cypermethrin dilutes 2000 times respectively, and clear water is contrast.
3, pest control: wheat aphid
4, dispenser is after 48 hours, and 3000 times of preventive effects of emulsion oil of Angulatin are 89.84%, 2000 times, and to be 94.41%, 1000 times be 94.74%; 40% flolimat is 98.88% for 2000 times; 101% cypermethrin is 98.91% for 2000 times.
Influence to natural enemy: executed about back the 4th, 6,8 day, and observed accumulated result: spider, ladybug etc., emulsion oil of Angulatin is respectively 11 for 3000,2000,1000 times, and 6,19; 2000 times 3 of 40% flolimats; 10% chlorine oxygen chrysanthemum ester is 4; The clear water contrast is 20.
Evidence:
1, emulsion oil of Angulatin is remarkable to the wheat aphid control efficiency, and especially 1000 times control efficiency approaches 40% flolimat and 10% cypermethrin, and residual few, low toxicity.
2, obviously less to the lethality of natural enemy.
Embodiment 2, the percentage composition of emulsion oil of Angulatin:
Root bark of celastrus angulatus extract 10, OPEO 10, dimethyl formamide 3, dimethylbenzene 77.
Manufacture method is prevented and treated the wheat aphid test of pesticide effectiveness with embodiment 1, and mu formulation rate 509 dilutes 2000 times, is 95% to the wheat aphid preventive effect.Test also shows: to vegetable aphid control efficiency 80.4-87.9%; To cabbage caterpillar control efficiency 90.5-95.1%.
