Description
Technical field
The present invention relates to disinfectant use in agriculture field, specifically, refers to one kind and gathers containing fluorobenzene ether amide and chitin
The composition pesticide of sugar and its application, more particularly to a kind of agricultural chemicals system for being used to prevent and treat corps diseases especially powdery mildew
Agent and its with use.
Background technology
Powdery mildew is widely distributed in China, and the harm to dicotyledon is especially prevalent, and when powdery mildew occurs, host is aggrieved
Position growth is suppressed, and gradual chlorisis turns yellow, and it is dried-up to last full leaf withered spot occur, makes plant early withered when serious.After disease
Phase, in the mould layer of white powder shape be made up of mycelia and conidium, often there is the granular cleistothecium of many scattered black, and with this
Survive the winter, secondary spring carries out First aggression with ascospore.Powdery mildew is once occur, and spread speed is very fast, one Growing season of crops
Energy-conservation is repeatedly subjected to infect.Powdery mildew makes the crop products such as China's wheat, cucumber, grape therefore, prevent by extreme loss
The generation for controlling powdery mildew is significant to agricultural production.
Fluorobenzene ether amide（Develop code name Y13149）For new succinate dehydrogenase inhibitors, to the late blight of potato, water
The sheath and culm blight of rice, powdery mildew etc. have efficient sterilizing activity, have uptake and translocation, and with the low spy of resistance to rainwater shower, dosage
Point, preventive effect do not interact anti-apparently higher than like product thifluzamide, the bactericide with most of bactericide in the market
Property, while especially its bactericidal activity with wide spectrum can prevent and treat the multiple diseases in various crop, therefore as grinding at present
Study carefully focus, fluorobenzene ether amide structural formula is as follows：
。
Chitosan is a kind of natural polymerses, has special physicochemical property and bioactivity, extensive
Applied to different field, it can be applied to prevent and treat cucumber downy mildew, powdery mildew, late blight and virosis etc. as biological pesticide,
Long-term a large amount of uses of chemical pesticide, can cause the drug-fast generation of pathogen, bactericide compounded or mixture is in solution
State one of maximally efficient method of problem.Develop new product bactericide price is constantly soaring, and by contrast, exploitation is high with research
Effect, low toxicity, the compounding of low-residual and mixture has small investment, the lead time is short and is paid attention to both at home and abroad, numerous and confused increasing is developed
Development dynamics.Present inventor is tested by substantial amounts of indoor virulence and field control effectiveness test, is found surprisingly that fluorobenzene
After ether amide and chitosan compounding, the preventing and treating to multiple kinds of crops disease shows obvious synergistic function, by entering
One step research completes the present invention, and there is no the relevant report for being related to fluorobenzene ether amide and chitosan at present.
The content of the invention
It is an object of the invention to provide a kind of collaboration that can be reduced pesticide activity component usage amount, improve prevention effect
Synergetic pesticide composition.
Another object of the present invention is to provide the application of the composition pesticide, the composition pesticide is particularly suitable for
Prepare the medicine of preventing and treating corps diseases, including but not limited to powdery mildew etc..
Another object of the present invention also reside in provide it is a kind of prevent and control corps diseases method, including separate, according to
Secondary or fluorobenzene ether amide and chitosan is administered simultaneously, in the case of separate administration, order of administration is generally to prophylactico-therapeutic measures
As a result large effect will not be produced.
In order to achieve the above object, the present invention adopts the following technical scheme that：
A kind of composition pesticide, its active component mainly include fluorobenzene ether amide and chitosan, wherein, fluorobenzene ether amide and
The weight ratio of chitosan is 40:1-1：10, the weight ratio preferably 15:1-5：1.
Further, the weight ratio that fluorobenzene ether amide and chitosan account for composition in the composition pesticide is 5-70%,
Preferably 15-50%.
Further, the composition pesticide is in addition to active ingredient, remaining be the auxiliary commonly used in Pesticide formulation into
Point.
Further, the auxiliary element comprises at least a kind of surfactant and/or carrier.
Further, composition pesticide of the invention can be prepared into any one agent used in suitable agricultural production
Appointing in type, including but not limited to missible oil, granule, wettable powder, water dispersible granules, suspending agent, aqueous emulsion, microemulsion etc.
Meaning is a kind of.
Further, composition pesticide of the invention can also add other agricultural active compositions, including but not limited to other
One in the bactericide of species, insecticide, nematicide, herbicide, safener, synergist, plant growth regulator, fertilizer
Kind or more than one.
Compared with prior art, composition pesticide of the invention has the beneficial effect that：
1st, active testing result shows, the activity that fluorobenzene ether amide and chitosan are used in combination in composition pesticide of the invention
Two kinds of active components sum is significantly larger than used alone, both compoundings show certain association in the range of certain compound proportion
Same synergistic effect, it is possible to reduce pesticide activity component usage amount, improve prevention effect；
2nd, the active component mechanism of action is different in composition pesticide of the invention, and both compounding uses can increase preventing and treating and make
With site, be advantageous to delay the drug-fast generation of pathogen；
3rd, composition pesticide active component chitosan of the invention is biological bactericide, high to Environmental compatibility, and both compound
Composition pesticide security it is excellent.
