Description
Technical field
The invention belongs to pesticides application technical field, and in particular to a kind of bactericidal composition for preventing the late blight of potato.
Background technology
Asarum, Asarum sieboldii Miq, are that the band root of aristolochiaceae plant HERBA ASARI from Liaoning of China, asarum and Seoul asarum is complete
Grass, it is medicinal in can doing.Asarum is as medicinal plant, Shi Zai Qin Han《Sheng Nong's herbal classic》,《Sheng Nong's herbal classic》It is classified as top grade.
HERBA ASARI from Liaoning of China root is thin, color sallow, leaf color are green, the peppery numb tongue of acrid flavour.Asarum is warm-natured, slightly poisonous, the thoughts of returning home, lung, kidney channel.It has wind-dispelling, dissipates
Cold, warm lung, Hang Shui, the effect having one's ideas straightened out, controls anemofrigid headache, nasosinusitis, dentalgia, phlegm and retained fluid cough is inverse, arthralgia pain due to rheumatism.In addition, asarum also has
There are anti inflammatory immunity, local anaesthesia, improve metabolism, antibacterial action, also available for the white of Chemotherapy of Tumor Patients and caused by radiation
Leukopenia.Herba Asari volatile oil is the principle active component of asarum, many in industrial applications such as cosmetics, medicine, have antibacterial,
The curative effects such as anti-inflammatory, hemostasis, analgesia.
Mancozeb (Mancozeb) is a kind of excellent protective fungicide, belongs to low-toxin farm chemicals.Due to its bactericidal range
Extensively, resistance is not likely to produce, prevention effect is substantially better than other same series bactericidal agents, so dosage is always large-tonnage production in the world
Product.At present, domestic most composite bactericides are all formulated with Mancozeb processing, and manganese, zinc microelement have crop substantially
Rush strengthen, production-increasing function, be mainly used for preventing crop late blight, downy mildew, anthracnose, brown spot etc..
Whether Mancozeb or other fungicide are used alone for a long time, all easily disease is developed immunity to drugs, lead
The problem of dose of applying increases, preventive effect reduces.Produced to reduce resistance risk and delaying drug resistance, by the effective of the different mechanisms of action
Component is compounded, using being one of effective method.At present using Herba Asari volatile oil, Mancozeb as active ingredient group
Compound be applied to the late blight of potato research there has been no relevant report.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of bactericidal composition for preventing the late blight of potato, for preventing
The late blight of potato, it is good with preventive effect, resistance of rainwater washing against, can reduce chemical pesticide usage amount, low-residual, delays the anti-medicine of germ
Property produce, the features such as to crop and Environmental security.
The present invention solves above-mentioned technical problem and is achieved through the following technical solutions：A kind of sterilization for preventing the late blight of potato
Composition, active ingredient are made of Herba Asari volatile oil and Mancozeb, and the weight ratio of Herba Asari volatile oil and Mancozeb is 15-1:
1-8。
Preferably, the weight ratio of the bactericidal composition, Herba Asari volatile oil and Mancozeb is 3-1:1-3.
The Herba Asari volatile oil preparation method：Fresh asarum herb 1kg is selected, selected removing impurity, washes with water 1
It is secondary, when natural air drying 15 is small, pulverize and sieve 60 mesh；Utilize conventional supercritical carbon dioxide extracting, 5 liters of extraction kettle volume, extraction
Pressure power is 10mPa, 25 DEG C, time 1.5h, separation reactor I pressure 6mPa of extraction temperature, 30 DEG C of temperature, separation reactor I I pressure
6mpa, temperature are 34 DEG C, CO2 flow 20Kg/h, and recycling has the pale yellow transparent oily solution of special aromatic odor, per half an hour
Single extraction thing is collected, collects 38 grams of extract quality, yield 3.8% altogether.
The active ingredient of the bactericidal composition accounts for the 1-70% of bactericidal composition gross weight, and surplus is that can be connect on pesticide
The auxiliary element received.
The bactericidal composition is added made of corresponding auxiliary element according to method known in those skilled in the art
Formulation is wettable powder, water dispersible granules or suspending agent.
The auxiliary element that bactericidal composition of the present invention uses include dispersant, wetting agent, binding agent, disintegrant, antifreezing agent,
Defoamer, thickener, filler, solvent etc. or it is other be beneficial to active ingredient in the formulation stablize and drug effect play known substance
Matter, is all to be commonly used in field of pesticide preparation or allow the various composition used.
Beneficial effect of the present invention：The bactericidal composition that the present invention carries out mixture by Herba Asari volatile oil and Mancozeb is used for
The late blight of potato is prevented, obvious synergy, can effectively suppress infecting for germ.The bactericidal composition tool of the present invention
Have that preventive effect is good, resistance of rainwater washing against, can reduce chemical pesticide usage amount, low-residual, delays the germ resistance to the action of a drug to produce, to crop and ring
The features such as border is safe.
Embodiment
Technical scheme and technique effect are described further below in conjunction with specific embodiment, institute of the present invention
The percentage stated is weight percentage.
First, the preparation of Herba Asari volatile oil
The Herba Asari volatile oil preparation method：Fresh asarum herb 1kg is selected, selected removing impurity, washes with water 1
It is secondary, when natural air drying 15 is small, pulverize and sieve 60 mesh；Utilize conventional supercritical carbon dioxide extracting, 5 liters of extraction kettle volume, extraction
Pressure power is 10mPa, 25 DEG C, time 1.5h, separation reactor I pressure 6mPa of extraction temperature, 30 DEG C of temperature, separation reactor I I pressure
6mpa, temperature are 34 DEG C, CO2 flow 20Kg/h, and recycling has the pale yellow transparent oily solution of special aromatic odor, per half an hour
Single extraction thing is collected, collects 38 grams of extract quality, yield 3.8% altogether.
2nd, Toxicity Determination is tested
Test method：Reference《The 13rd parts of farm-chemical indoor determination test rule NY/T 1156.13-2008：Suppress
Late disease bacteria pilot blade method》, potato healthy leaves is handled with the reagent spray for preparing respective concentration, after 24h, with preparation
Good spore suspension even spraying, 5-7d is cultivated under suitable humiture and illumination condition, waits blank control disease leaf rate to reach
During to more than 50%, incidence is managed in classification investigation everywhere, calculates disease index and prevention effect.
Prevention effect is converted into niqueMin (y), and liquor strength (μ g/ml) is converted into numerical value (x), in terms of least square method
Virulence regression equation (y=a+bx) is calculated, and thus calculates the EC of every kind of medicament50Value.It is according to the common poison of the abundant methods of Sun Yun at the same time
Number methods (CTC) evaluate the synergistic effect of pharmacy mix, i.e. CTC≤80, and composition shows as antagonism, when 80<CTC<
120, composition shows as summation action, and when CTC >=120, composition shows as synergistic effect.Result of the test such as table 1.
