Abstract

An agricultural diochemical is prepared from the gingko testa through separating water-soluble substance, extracting liposobule substance by alcohol or petroleum ether, and dissolving it in 80% of alcohol solution. It features the integration of broad-spectrum insecticide, bactericide and plant growth regulator.

Description

Utilize the biopesticide and the preparation method of the preparation of gingko episperm fat-soluble extract
The present invention relates to botanical pesticide and preparation method, particularly utilize the biopesticide and the preparation method of gingko episperm fat-soluble extract preparation.
A lot of plants contain desinsection, Fungicidal active substance, and are utilized and are developed as biopesticide.For example the Chinese Academy of Sciences Kunming Phytochemistry Luo Xiaodong of open laboratory, Wu Shaohua etc. are published in " research and development of natural products ".Calendar year 2001 first-phase " insecticidal activity of neem extract and wherein four fall a triterpene research " literary composition, its achievement in research is that to contain nimbin be 0.5% nimbin extract when 150-800 times of dilution pest such as diamond-back moth and imported cabbageworm is had very strong desinsection food refusal to suppress the insect growth, delay the insect ovum, suppress the insect hormone secretion, reduce physiologically actives such as insect fecundity.It extracts with separating method: through the 1.36Kg of air-dry pulverizing neem kernel, with petroleum ether degreasing 3 times, degreasing kind benevolence is extracted 4 times with methanol eddy, methanolic extract, extract is used benzinum, ethyl acetate extraction three times successively.Acetate second extract is the neem extract that contains 0.5% nimbin.And for example Gansu Province's plant test station for plant protection Diao Shao east, Wang Jing etc. are published in " agricultural chemicals " 1999 the 6th phases " plant insecticide 2.5% datura flower alkaloid aqua Application and Development technical research " literary composition, research of botanical pesticide 2.5% datura flower alkaloid aqua and the newest fruits of using have been reported, carrying out indoor, field control effectiveness test result from 1995-1997 shows, 2.5% datura flower alkaloid aqua, 112.5-187.5g (effective ingredient) is to broccoli aphid, cabbage caterpillar control efficiency 79.54%-90.60%.
The botanical pesticide of above-mentioned preparation extracts from seal chinaberry and datura flower plant corpus respectively contains insecticide active substance, the biopesticide of nimbin and the preparation of datura flower alkaloid extraction liquid.
The task of this invention is: the gingko episperm that development and use are dropped, separation and Extraction fat-soluble composition wherein, be prepared into biopesticide, to pest such as all kinds of aphids, cabbage caterpillar, moss horse, tussock caterpillar, leek ground maggots, cucumber downy mildew, ginkgo leaf rot are had good preventive and therapeutic effect, and the growth to crop simultaneously has certain regulating action.The method that solves task of the present invention is: the gingko episperm that is soaked in water, separate and remove water-soluble components, again with benzinum or ethanol extraction 2 times, fat-soluble extract.Fat-soluble extract is dissolved in the 80% above ethanol, is mixed with the biopesticide that contains 15% left and right sides gingko episperm fat-soluble extract, ethanol is again emulsifier both as solvent.
Ginkgo is a gymnosperm, and seed is divided into kind of nuclear (gingko) and exosper two parts, 1 part of kind nuclear, 3 parts of exospers, exosper is dropped the flavor that gives out a foul smell, contaminated environment, and the present invention is to be raw material with the gingko episperm, the preparation biopesticide so both can be turned waste into wealth, and can remove environmental pollution again.
The biopesticide of gingko episperm fat-soluble extract preparation is extremely low to the person poultry toxicity.Do not cause environmental pollution, insect does not develop immunity to drugs.And be the agricultural chemicals that integrates pest control, germ, plant growth regulator.
Embodiment of the present invention is: 1, extract the gingko episperm liposoluble substance:
(1) with gingko episperm impurity elimination, cleaning, pulverizing.
(2) gingko episperm after will pulverizing adds 5 times water and is that 50-70 degree centigrade was soaked 10 hours, emit water after, same again the immersion once emitted immersion water.
(3) add 5 times of 95% ethanol or benzinum in 70 degrees centigrade of extractions 2 times.
(4) extract is filtered, concentrates and separation and Extraction liposoluble fluidity extract.
2, preparation biopesticide method: the fat-soluble extract with 15% is dissolved in the 80% above ethanol, filters, and is biopesticide.Ethanol is both as solvent, again as emulsifier.

Claims (5)

1, utilize the biopesticide of gingko episperm fat dissolubility extract preparation to crop pests such as various aphids, cabbage caterpillar, thrips, leek root maggots, corps diseases such as cucumber frost thunder disease, ginkgo dead leaf disease are had preventive and therapeutic effect, and the growth of crop is had regulating action.
2, the method for preparing biopesticide:
(1), the separation and Extraction of gingko episperm fat-soluble extract.
A, with the gingko episperm impurity elimination, clean, dry, pulverize.
B, in the gingko episperm of pulverizing, add 5 times water, soaked 10 hours at every turn, soak twice, emit immersion water in 50-70 degree centigrade.
C, 5 times of 95% ethanol of adding or benzinum are in 70 degrees centigrade of extractions 2 times.
D, extract is filtered, concentrates, and the separation and Extraction fat-soluble extract.
(2), preparation biopesticide: the fat-soluble extract with 15% is dissolved in the 80%-95% ethanol, filters, and is biopesticide.Ethanol is solvent, also is emulsifier.
3, according to claim 1, utilize gingko episperm to refer to the biopesticide that dissolubility extract system is equipped with, can have one-sided preventive and therapeutic effect, for example prevent and treat pest or disease or coordinate plant growth.
4, according to claim 2, extractant can be ethanol, benzinum, also can be other extractants.
5, according to claim 2, the biopesticide of preparation contains the content difference of ginkgo exosper fat-soluble extract, and preventive and therapeutic effect effect difference.
