Abstract
The invention discloses a kind of Synergistic composition pesticide comprising terpenol and amino-oligosaccharide, the weight of active component terpenol and amino-oligosaccharide ratio is 1 in the composition pesticide:20‑10：1, preferably 1:10‑5:1；The Synergistic composition pesticide of the present invention can be prepared into any one formulation used in suitable agricultural production, including but not limited to any of missible oil, wettable powder, water dispersible granules, suspending agent, microemulsion, aqueous emulsion, soluble liquid.The collaboration composition pesticide of the present invention is worthy of popularization to crop safety.
Description
Technical field
The invention belongs to technical field of pesticide combination, and in particular to be a kind of agriculture comprising terpenol and amino-oligosaccharide
Drug composition, and its for preventing and treating the purposes of corps diseases.
Background technology
Powdery mildew of cucumber powder disease is commonly called as " white hair disease ", aggrieved most heavy with blade, next to that petiole and stem, do not endanger fruit typically
It is real.Early stage, the blade of face of blade powdery mildew of cucumber harm or the back side produce the small amyloid plaque of white subcircular, gradually expand
The unconspicuous large stretch of white powder area in great achievement edge, is covered with blade face, as having spread layer white powder.Erase white powder, it is seen that blade face chlorisis is withered and yellow
Become fragile.When falling ill serious, blade face is covered with white powder, becomes canescence, until whole blade is withered.Powdery mildew infects petiole and tender stem
Afterwards, symptom is similar on blade, and only scab is smaller, and powder is also few.Start to produce yellow dot on blade, then expand
Circular or oval scab is developed into, there is the mould layer of white powder on surface.Ordinary circumstance bottom blade is more than upper blade, blade
The back side is more than front.Mildew early stage is individually scattered, after be unified into a big mildew, it might even be possible to cover full leaf, have a strong impact on light
Cooperation is used, and eubolism is interfered, is caused early ageing, yield incurs loss.Because in recent years, powdery mildew produces certain
The resistance to the action of a drug, and can fall ill throughout the year, bring certain difficulty to preventing and treating.The general time underproduction is 10% or so, the popular time
The underproduction is in 20%-40% or so.
Terpenol is the biological bactericide that Israel's biological pesticide discloses exploitation, at present, existing 40.2% terpenol mother's medicine
With 9% terpenol missible oil success industrialization, for preventing and treating the diseases such as powdery mildew of strawberry and early blight of tomato.
Amino-oligosaccharide（Chitosan oligosaccharide）Refer to D- Glucosamines with the oligosaccharide of β -1.4 glucosides key connections, by chitin
Say and solve less toxic bactericide that is obtained, or being extracted by microbial fermentation of degrading again after chitosan.Amino-oligosaccharide can be to some diseases
The growth of bacterium produces inhibitory action, influences the sprouting of fungal spore, hypha form morphs, biochemistry changes in spore for induction
Deng.Gene in energy activated plant body, produce the chitinase with resistant effect, dextranase, protect element and PR albumen etc., and have
Cell activation acts on, and contributes to the recovery of aggrieved plant, promoting root growth strong sprout, strengthens the resistance of crop, promote growth and development of plants.
Amino-oligosaccharide solution has antivirus, bactericidal, fungicidal action.Not only have to bacterium, fungi, virus extremely strong preventing and treating and
Eradicant action, but also there is nutrition, regulation, removing toxic substances, antibacterial.Not only fungi, bacterium, virus are prevented with extremely strong
Control and eradicant action, but also the effect of with nutrition, regulation, removing toxic substances, antibacterial.It can be widely used for preventing and treating fruit tree, vegetables and cotton
The disease such as mosaic disease, powdery mildew, little leaf, spot disease, anthracnose, downy mildew, epidemic disease caused by grain crop.
Although amino-oligosaccharide and terpenol have been applied to preventing and treating corps diseases, pesticide activity component is independent for a long time
Using the drug-fast generation of pathogen can be caused, prevention effect is caused to decline, dosage increases, and is unfavorable for the sustainable development of environment
Exhibition.The active component of different action of agricultural chemicals mechanism is compounded, is one of main path for solving resistance development, the application's
Inventor on the basis of lot of experiments, find by terpenol and amino-oligosaccharide compounding after in certain scope to a variety of agricultures
The preventing and treating of crop disease shows certain synergistic function, completes the present invention after further research, there is no at present
The relevant report compounded on both.
The content of the invention
It is an object of the invention to provide a kind of prevention effect is good, cost is low, environment amenable Synergistic agricultural chemicals group
Compound.
Another object of the present invention is to provide to be used to prepare preventing and treating corps diseases by the collaboration composition pesticide
Application in medicine, the Synergistic composition pesticide, which is particularly suitable for use in, prevents and treats powdery mildew.
A kind of method for preventing and treating corps diseases, including by the Synergistic composition pesticide and crop or plant growth
Environment directly contact.
In order to achieve the above object, the present invention adopts the following technical scheme that：
A kind of Synergistic composition pesticide, its active component include terpenol and amino-oligosaccharide, wherein, terpenol and ammonia
The weight ratio of base oligosaccharide is 1:20-10：1, further, the weight ratio of the terpenol and amino-oligosaccharide is preferably 1:
10-5：1.
Further, the weight percentage of active component is 5-40% in the Synergistic composition pesticide, is preferably
10-20%, remaining is auxiliary element conventional in Pesticide formulation.
Further, the Synergistic composition pesticide can be prepared into any one used in suitable agricultural production
In formulation, including but not limited to missible oil, wettable powder, water dispersible granules, suspending agent, microemulsion, aqueous emulsion, soluble liquid
It is any.
Further, other agricultural active compositions can also be added in the Synergistic composition pesticide, including but not
The one or more being limited in bactericide, insecticide, biostimulant, plant growth regulator, synergist, fertilizer.
Further, Synergistic composition pesticide of the invention can offer be each in composition in the form of finished product preparation
Material is blended, can also be provided with unit dose form, is directly mixed in proportion in bucket or tank using preceding, is then diluted to institute
The concentration needed.
Compared with prior art, Synergistic composition pesticide of the invention has the beneficial effect that：
（1）It is not simple superposition between terpenol and amino-oligosaccharide in the composition pesticide of the present invention, both compound
The preventing and treating to corps diseases in certain scope shows as synergistic function afterwards, it is possible to reduce pesticide activity component uses
Amount, improve prevention effect；
（2）The active component mechanism of action is different in the composition pesticide of the present invention, can be with increasing action site, effectively anti-
While controlling corps diseases, the drug-fast generation of pathogen can be delayed；
（3）Composition pesticide dosage of the invention is low, prevention effect is good, to Environmental compatibility height.
