Description
Technical field
The invention belongs to plant protection field, it is related to the bactericidal composition containing chitin Yu bromothalonil, composition to use
In the disease control of preventing and treating fruit tree, vegetables, grain, cotton, oil plant, flowers etc..
Background technology
Come from organism and the great interest of the good compound of the biodegradability person that caused pesticide research.At this
In a little compounds, have no toxic side effect, the chitosan oligosaccharide of easily biological-degradable has very big potentiality, the new medicament as control disease.
Research shows, chitin, especially chitosan oligosaccharide are being resisted during pathogen corrodes, used as the important plant of a class
Induction antiviral agents, can induce and excite plant to produce a series of defense reaction, these defense reactions synergy to prevent pathogen
Propagation and invasion, reach the effect prevented and cured diseases.
Bromothalonil (bromothalonil), molecular formula is C6H6Br2N2, chemical name is the bromo- 2 bromomethyl glutaronitriles of 2-,
With unique protection, interior suction treatment and shoveling function, it is adaptable to the fungi of each fruit trees, crop, vegetables and tobacco, medicinal material etc.
Property, bacillary, virus disease preventing and treating, effect is significant, lasting period are long.After using medicament, can be absorbed by somatic cells rapidly,
And conducted in somatic cells, and the normal development of somatic cells is disturbed, so as to reach antibacterial, bactericidal action, and work can be stimulated
The activity of various enzymes in object, increase photosynthesis, leaf color are dark green, robust plant, and improve crop yield.
It is long-term continuously to apply single chemical bactericide, easily cause residual, environmental pollution and the resistance medicine of medicament
Property the problems such as, and the compounding of biological pesticide and chemical bactericide have expand fungicidal spectrum, improve prevention effect, reduce dosage,
The features such as reducing residual, delay the resistance to the action of a drug.The report that there is no the composition on chitin derivativ and bromothalonil to study at present,
Inventor has found that composition tool has an unexpected effect.
The content of the invention
It is an object of the invention to provide the bactericidal composition containing chitin Yu bromothalonil, it be by two kinds not
Same structure, the sterilization component of the different mechanisms of action are compounded, and can be expanded preventing and treating spectrum and be improved drug effect.The purpose of the present invention is
Realized by following measures.
Bactericidal composition containing chitin Yu bromothalonil, chitin is 1 with the mass ratio of bromothalonil：
50-5:1, chitin is one or more in chitin, shitosan or chitosan oligosaccharide in composition.
Bactericidal composition of the invention, it is preferred that chitin is 1 with the mass ratio of bromothalonil:35-1:5, enter one
Step is preferred, and mass ratio is 1:25.
Bactericidal composition of the invention, it is preferred that chitin is shitosan or chitosan oligosaccharide.
Chitin accounts for the 1-80% of composition gross mass with the quality sum of bromothalonil in the present composition.
The present composition can be made into microemulsion, aqua, water dispersible granules, wettable powder, suspending agent, missible oil, water and milk
Agent, microcapsule formulations etc., it is preferred that composition is made microemulsion.
Present invention also offers the controlling plant diseases and the purposes of raising crop yield of above-mentioned composition, disease is anthrax
Disease, scab, downy mildew, leaf spot, powdery mildew, peronospora tabacina, smut, ring spot etc..Preferably, disease be anthracnose,
Scab or downy mildew.
In such use, the plant that composition is applied is melon fruits and vegetables, grain and cotton, flowers, the grass cultivated for human needs
Level ground plant etc., it is preferred that plant is oranges and tangerines, mango, apple, cucumber, grape, wheat, watermelon, pears, lichee, paddy rice, flowers, grass
Level ground etc..
Present invention has the advantages that：
1st, synergistic effect is obvious：Composition shows good synergistic effect in certain ratio range.
2nd, preventing and treating spectrum is expanded：Composition can prevent and treat the multiple diseases on plant.
3rd, use cost is reduced：Preventive effect, preventing and treating spectrum increase are improved because compounding has, access times are reduced, is reduced and is used
Cost；
4th, the resistance to the action of a drug is delayed：Two kinds of composition compoundings of different mechanism of action, pathogen is not likely to produce the resistance to the action of a drug, delays cause of disease
Thing is to the drug-fast generation of single dose.
