Abstract
The invention relates to an application method of laurolitsine, namely, application in preparation of pesticides; the laurolitsine is prepared into a conventional dosage form by a conventional method, and the effective pest killing concentration of the laurolitsine can be mg / L. The pesticides prepared by the method are significant in effect and environmental friendly.
Description
Technical field
The present invention relates to field of pesticides, especially natural insecticide technical field.
Background technology
Agricultural chemicals is being brought into play very important effect in agricultural production.After 20th century invention forties organic chemistry agricultural chemicals, greatly strengthen the mankind and controlled the ability that disease worm endangers, for we retrieve crop yield loss, made great contribution.But dependence for a long time and a large amount of Synthetic Organic Chemistry agricultural chemicals that use, brought the series of problems such as well-known environmental pollution, ecological balance destruction and food security, promotion agricultural economy realized to sustainable development and bring many adverse influences.
Along with the raising of health of people consciousness, Chinese Shi Yige large agricultural country.Most countries is all paid much attention to the safety of agricultural product, very strict to the restriction of residue of pesticide.China is after accession to WTO, and agricultural product entrance is faced with very severe green barrier " its Pesticide Residues exceeds standard is often to encounter problems, and has had a strong impact on the competitiveness of agricultural products in China in international market.In order to reduce persticide residue, making great efforts development of new agricultural chemicals has become the task of top priority.
Botanical pesticide claims again botanical pesticide.Utilize the agricultural chemicals of plant resource explorations.
Comprise the active component that extracts, plant itself and by the synthetic compound of active structure and derivative from plant.Classification has phytotoxin, plant endogenous hormones, botanical insect hormone, anti-feedant, attractant, repellant, chemosterilant, synergist, plant defense element, allelopathic substances etc.
Press effective ingredient, chemical constitution and purpose classification: alkaloid, terpenes, flavonoids, essential oil class, photoactivation toxin.Botanical pesticide is an important component part of biopesticide.It refers to the contained stable active ingredient in some position (root, stem, leaf, flower or fruit) of utilizing plant, after recipient plant being used by certain method, it is exempted from or alleviate the plant resource preparation that the pests such as disease, worm, weeds are caused harm.The plant resources that botanical pesticide utilizes is poisonous plant.So botanical pesticide is popular is again " pesticide made of Chinese medicinal herbs ".
Litsea pungens alkali (Laurolitsine), CAS accession number: 5890-18-6, molecular formula C

4.
litsea pungens alkali often, as the raw material of synthetic other active substance, has very high economic worth.
In prior art, about Litsea pungens alkali, do not there is the report of insecticidal activity.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of application method of Litsea pungens alkali, is used as and prepares insecticide.
In order to solve the problems of the technologies described above, the present invention proposes following technical proposal:
Litsea pungens alkali is applied in preparing insecticide.
Preferably, Litsea pungens alkali is applied in preparing insecticide as unique active component.
Described insecticide can be killed mythimna separata, Tetranychus cinnabarinus, black peach aphid and Brown Planthopper.
Described insecticide can be made conventional formulation.
Described formulation can be aqua or pulvis.
Beneficial effect of the present invention can be by following evidence
Test example 1 Litsea pungens alkali is measured four kinds of experiment target target contact toxicities
(1) test medicine
Purity 98.9% is extracted in the self-control of Litsea pungens alkali from the root of three-nerved spicebush.
(2) test target
Mythimna separata (Mythimna sepatara), Tetranychus cinnabarinus (Tetranychus cinnabarinus), black peach aphid (Myzus persicae), Brown Planthopper (Nilaparvata lugens).Above worm kind is the indoor worm kind of throughout the year for many generations raising.
(3) instrument and equipment
Electronic analytical balance, culture dish, liquid-transfering gun, card punch, writing brush etc.
(4) liquid preparation
With analytical balance (0.0001g), take the former medicine of certain mass, with DMF, dissolve and be mixed with 1% mother liquor.Measure a certain amount of mother liquor, add and contain the liquid that 0.1% Tween-80 distilled water diluting is mixed with mensuration desired concn, standby.
(5) test method
A, mythimna separata screening---leaf dipping method
After fully being infiltrated in the liquid preparing, the maize leaves section shearing in right amount naturally dries in the shade, put into the culture dish that is lined with filter paper, connect 10/ware of mythimna separata larva in 3 mid-term in age, add a cover mark and be placed on and be placed in 24-26 ℃, in the observation ward of 14h illumination, cultivate 2d " Invest, Then Investigate " result.The 0.1% tween water of take is blank.With writing brush, touch polypide, be reactionlessly considered as dead worm.
B, Tetranychus cinnabarinus screening---spray-on process
Broad Bean Leaves is broken into leaf dish, and the back side is placed on fritter cotton upward, is placed in plastic culture dish, adds a small amount of water, connects Tetranychus cinnabarinus and becomes mite.After becoming mite stable on blade, leaf dish is placed under Potter spray tower to quantitatively (2.5mL) spraying and processes that (pressure is 5lb/in2, settling amount is 4.35mg/cm2), the tween water that test is established containing the organic solvent of maximum concentration is blank, naturally dries to be placed on and observes indoor feeding and observation.Check result after 48 h.With writing brush, touch polypide, be reactionlessly considered as dead worm.
C, black peach aphid screening---spray-on process
Broad Bean Leaves is broken into leaf dish, and the back side is placed on fritter cotton upward, is placed in plastic culture dish, adds a small amount of water, if connect aphis craccivora aphid mixed population.Wait try worm stable on blade after, leaf dish is placed under Potter spray tower to quantitatively (2.5mL) spraying and processes that (pressure is 5lb/in2, settling amount is 4.35mg/cm2), the tween water that test is established containing the organic solvent of maximum concentration is blank, naturally dries to be placed on and observes indoor feeding and observation.Check result after 48 h.With writing brush, touch polypide, be reactionlessly considered as dead worm.
D, brown planthopper screening---spray-on process
Adopt Potter spray-on process.The rice seedling (being about 3～4cm) that is about to 4～6 2 leaf 1 hearts is fixed in the culture dish of Φ 7cm with crystobalite sand, Brown Planthopper nymph in 3 mid-term in age is with after CO2 anesthesia, every ware connects 30～40, be placed under Potter spray tower quantitatively (2.5mL) spraying and process that (pressure is 5lb/in2, settling amount is 4.35mg/cm2), the tween water that test is established containing the organic solvent of maximum concentration is blank, after spraying, with transparent plastic cup, cover, be placed in 27 ℃, in the observation ward of 14h illumination, cultivate 3d " Invest, Then Investigate " result.With writing brush, touch polypide, be reactionlessly considered as dead worm.
Add up the dead borer population of each processing and the borer population of living, calculate lethality.
(6) result of the test
Result of the test is in Table 1, and result shows, Litsea pungens alkali has good insecticidal activity.
According to the different objects of killing, the valid density of Litsea pungens alkali kill pests can make 1.0-500mg/L.
During use, according to circumstances, can adopt conventional method that Litsea pungens alkali is made to regular dosage form.
In order better to set forth technical scheme of the present invention, below in conjunction with embodiment, the present invention is further illustrated, but protection domain of the presently claimed invention is not limited to the following example.
