Abstract
The present invention relates to the application processes of curculigoside, i.e., are applied in insecticide is prepared, the insecticide significant effect that is prepared using this method, environmental-friendly.
Description
Technical field
The present invention relates to field of pesticides, especially natural insecticide technical field.
Background technology
Pesticide plays highly important effect in agricultural production.Invention the 1940s organic chemical pesticides it
Afterwards, the ability that the mankind control disease pest harm is significantly enhanced, crop yield loss is retrieved for us and has made great tribute
It offers.But long-term rely on uses Synthetic Organic Chemistry pesticide with a large amount of, has had resulted in well-known environmental pollution, ecology
A series of problems, such as balance destruction and food security, to agricultural economy is promoted to realize, sustainable development brings many detrimental effects.
With the raising of people's health consciousness, China is a large agricultural country.Most countries all pay much attention to agricultural product
Security, it is very stringent to the limitation of pesticide residue.After accession to WTO, agricultural product entrance is faced with very severe for China
Green barrier " wherein pesticide residue is exceeded is to frequently encounter problem, seriously affected agricultural products in China in the competing of international market
Strive power.In order to reduce persticide residue, make great efforts exploitation novel agrochemical and have become the task of top priority.
Botanical pesticide is also known as botanical pesticide.Utilize the pesticide of plant resource explorations.
Including extracted from plant active ingredient, plant in itself and by active structure synthesis compound and derivative.
Classification has phytotoxin, plant endogenous hormones, botanical insect hormone, anti-feedant, attractant, repellant, chemosterilant, synergy
Agent, plant defense element, allelopathic substances etc..
By effective ingredient, chemical constitution and purpose classification：Alkaloid, terpenes, flavonoids, essential oil class, light-activated toxin.
Botanical pesticide is an important component of biological pesticide.It refers to some positions using plant（Root, stem, leaf, Hua Huo
Fruit）The active ingredient of contained stabilization, after carrying out use to recipient plant by certain method, make its exempt from or mitigate disease,
The plant source preparation that the harmful organisms such as worm, weeds are caused harm.The plant resources that botanical pesticide is utilized is poisonous plant.So
It is " pesticide made of Chinese medicinal herbs " that botanical pesticide is again popular.
Curculigoside (Curculigoside)
CAS:85643-19-2
Molecular formula：C22H26O11
Molecular weight：466.44
Structural formula is as follows：
In the prior art, there is no the reports on curculigoside with insecticidal activity.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of application process of curculigoside, are used as preparing insecticide.
In order to solve the above-mentioned technical problem, the present invention proposes following technical proposal：
Curculigoside is applied in insecticide is prepared.
Preferably, curculigoside is applied as sole active agent in insecticide is prepared.
The insecticide can kill Tetranychus cinnabarinus, Brown Planthopper.
Conventional dosage form can be made in the insecticide.
The dosage form can be aqua or pulvis.
Beneficial effects of the present invention can be proved by following experiment
1 curculigoside of test example measures the contact toxicity of target worm
（1）Test medicine
Curculigoside, purity >=99.0%.
（2）Test target
Tetranychus cinnabarinus（Tetranychus cinnabarinus）, Brown Planthopper（Nilaparvata lugens）.With
Upper worm kind for many generations raises worm kind throughout the year to be indoor.
（3）Instrument and equipment
Electronic analytical balance, culture dish, liquid-transfering gun, card punch, writing brush etc..
（4）Drug solution preparing
The active compound of certain mass is weighed with assay balance, dissolved with DMF and is configured to 1% mother liquor.Measure a certain amount of mother
Liquid adds the liquid for being configured to measure required concentration containing the dilution of 0.1% Tween-80 distilled water, spare.
（5）Test method
A, Tetranychus cinnabarinus screens --- spray-on process
Broad Bean Leaves are broken into leaf dish, the back side is placed on fritter cotton, is placed in plastic culture dish upward, adds a small amount of water,
Tetranychus cinnabarinus is connect into mite.After stablizing on blade, leaf dish is placed in after into mite under Potter spray towers quantitative（2.5mL）Spraying
Processing（Pressure is 5lb/in2）, experiment sets the tween water of the organic solvent containing maximum concentration as blank control, after naturally dry
It is placed in observation ward and raises and observe.Inspection result after 48 h.Polypide is touched with writing brush, it is reactionless to be considered as dead worm.
B, brown paddy plant hopper is screened --- spray-on process
Using Potter spray-on processes.I.e. by the rice seedling of 4~6 2 leaf, 1 hearts（It is about 3~4cm）Use crystobalite
Sand is fixed in the culture dish of Φ 7cm, and after Brown Planthopper 3 age mid-term nymph is anaesthetized with CO2,30~40 are connect per ware
Head is placed under Potter spray towers quantitative（2.5mL）Spraying treatment（Pressure is 5lb/in2）, test and set containing maximum concentration
The tween water of organic solvent is blank control, is covered after spraying with transparent plastic cup, is placed in 27 DEG C, in the observation ward of 14h illumination
It cultivates, investigation result after 3d.Polypide is touched with writing brush, it is reactionless to be considered as dead worm.
The dead borer population of each processing and borer population living are counted, calculates the death rate.
（6）Result of the test
Result of the test is shown in Table 1, the results showed that, curculigoside has good insecticidal activity.
Table 1 tests experiment target target insecticidal activity
According to different objects of killing, the effective concentration that curculigoside kills pest can make 1.0-500mg/L.
In use, according to circumstances, conventional method may be employed, regular dosage form is made in curculigoside.
In order to preferably illustrate technical scheme, the present invention is made With reference to embodiment further
Illustrate, but protection domain of the presently claimed invention is not limited to the following example.
Specific embodiment
Embodiment 1
Curculigoside is taken, by 1:100 mass ratio adds in dextrin, is uniformly mixed to get curculigoside insecticidal dust.
Embodiment 2
Curculigoside is taken, dissolved with DMF and is configured to 1% solution to get curculigoside aqueous solution of insecticide.
Claims (1)
1. curculigoside is applied in insecticide is prepared, it is characterised in that the insecticide can kill Tetranychus cinnabarinus, Rice Brown
Plant hopper.
