Abstract
The present invention relates to the application process of acetyl wild jujube glycosides B, i.e., applied in insecticide is prepared, acetyl wild jujube glycosides B is applied as sole active agent in insecticide is prepared, and the insecticide prepared can kill mythimna separata.It is 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
Offer.But rely on for a long time and largely use Synthetic Organic Chemistry pesticide, have resulted in well-known environmental pollution, ecology
A series of problems, such as balance destruction and food security, to promoting agricultural economy to realize that 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, the limitation to pesticide residue is very stringent.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 (root, stem, leaf, the Hua Huo using plant
Fruit) contained by stabilization active ingredient, 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.
Acetyl wild jujube glycosides B (Acetyljujuboside B)
CAS:194737-13-8
Molecular formula：C54H86O22
Molecular weight：1087.26
Structural formula is as follows：
In the prior art, not there is the report of insecticidal activity on acetyl wild jujube glycosides B.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of application process of acetyl wild jujube glycosides B, are killed as preparation
Worm agent.
In order to solve the above-mentioned technical problem, the present invention proposes following technical proposal：
Acetyl wild jujube glycosides B is applied in insecticide is prepared.
Preferably, acetyl wild jujube glycosides B is applied as sole active agent in insecticide is prepared.
The insecticide can kill mythimna separata.
Conventional formulation can be made in the insecticide.
The formulation can be aqua or pulvis.
Beneficial effects of the present invention can be proved by following experiment
1 acetyl wild jujube glycosides B of test example measures the contact toxicity of target worm
(1) test medicine
Acetyl wild jujube glycosides B, purity >=99.0%.
(2) target is tested
Mythimna separata (Mythimna sepatara).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, is 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
Mythimna separata is screened --- leaf dipping method
Dry in the shade naturally after the maize leaves section sheared in right amount is fully infiltrated in the liquid prepared, be put into the training for being lined with filter paper
Support in ware, connect mythimna separata 3 age mid-term larva, 10/ware, capping mark, which is placed on, is placed in 24-26 DEG C, is trained in the observation ward of 14h illumination
Support, investigation result after 2d.Using 0.1% tween water as blank control.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, acetyl wild jujube glycosides B has good insecticidal activity.
Table 1 tests experiment target target insecticidal activity
According to different objects of killing, the valid density that acetyl wild jujube glycosides B kills pest can make 1.0-500mg/L.
In use, according to circumstances, acetyl wild jujube glycosides B can be made by regular dosage form using conventional method.
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.
Embodiment
Embodiment 1
Acetyl wild jujube glycosides B is taken, by 1:100 mass ratio adds dextrin, is uniformly mixed, up to acetyl wild jujube glycosides B insect powders
Agent.
Embodiment 2
Acetyl wild jujube glycosides B is taken, is dissolved with DMF and is configured to 1% solution, up to acetyl wild jujube glycosides B aqueous solution of insecticide.
Claims (1)
1. acetyl wild jujube glycosides B is applied in insecticide is prepared, it is characterised in that：Acetyl wild jujube glycosides B exists as sole active agent
