Description
Technical field
The invention belongs to crop disease control field, and in particular to a kind of killing comprising Er Lv Evil bacterium azoles and copper 8-hydroxyquinolinate
Bacteria composition, and its for preventing and treating the application of corps diseases, especially downy mildew, epidemic disease, samping off.
Background technology
In plant growing process, easily infected, got up for a long time by various diseases, chemical prevention is controlling disease master
The means wanted, chemical prevention has the advantages that prevention effect is fast, effect is good, but due to long-term single kind using chemical pesticide and
Scientific Usage of Drugs, does not cause various plants disease fungus to generate resistance to agricultural chemicals, further causes dosage increasing, causes
The consequence that drug cost rise, environmental threat are increased, has had a strong impact on the sustainable development of green agriculture.Therefore, exploitation can
The new varieties of pesticides that the pathogen resistance to the action of a drug is produced, prevention effect is good, cost is low is delayed to turn into the problem for needing to overcome in research.
Er Lv Evil bacterium azoles is the Yi Zhong oxazole sulfone series bactericidal agents found by Guizhou University.Sulfone compound is because with wide spectrum life
Thing is active and causes concern of the people to it, and especially sulfone group is incorporated into a variety of compound structures, passes through knot
Structure modification can produce a series of compounds with broad-spectrum biological activity so that it has given play in novel super-high effect pesticides discovery
More and more important effect.
Copper 8-hydroxyquinolinate, belongs to new organic copper series bactericidal agent, is reacted and generated by 8-hydroxyquinoline and copper sulphate, organic quinolines with
Mantoquita has double sterilization effect；The synthesis of the G- protein of early stage cell expression can be suppressed, suppress germ spore new old generation
Thank, control cell divides and broken up again, has multiple spot contact toxicity concurrently again, the pathogen spore sprouted using chelated copper is inhaled
Receive, spore cell is directly killed inside pathogen, so as to reach the effect prevented and cured diseases.Crop is caused by fungi, bacterium
Multiple diseases have significant kill and inhibitory action.
The mixture bactericide of the especially different mechanisms of action of variety classes is expected to reach expansion preventing and treating spectrum, enhancing preventive effect, prolonged
The drug-fast advantage of slow pathogen, turns into most popular application form, in the application, searching can reach in production practices
The bactericide of synergistic function can reach the effect got twice the result with half the effort, thus enjoy researcher to favor.Present inventor
By substantial amounts of indoor measurement and field test, be found surprisingly that by its prevention effect after Er Lv Evil bacterium azoles and oxine-copper composite by
In the theoretical summation that effect is used alone, the present invention is completed after further research, is found by comprehensively retrieval, at present still
Do not find with the relevant report on Er Lv Evil bacterium azoles and oxine-copper composite.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of efficient, low toxicity, pathogen can be delayed to resist
The synergistic sterilizing composition that the property of medicine is produced.
Another object of the present invention is to provide the application of the Synergistic bactericidal composition, the Synergistic bactericidal composition is used
In the application for the medicine for preparing preventing and treating corps diseases, the corps diseases include potato, tomato, grape, tobacco, Huang
The oomycetes diseases of the crops such as melon, lettuce.
In order to achieve the above object, the present invention is adopted the following technical scheme that：
A kind of Synergistic bactericidal composition, its active component at least includes Er Lv Evil bacterium azoles and copper 8-hydroxyquinolinate, wherein, Er Lv Evil bacterium azoles
Mass ratio with copper 8-hydroxyquinolinate is 1:20-20:1, further, the weight ratio of the Er Lv Evil bacterium azoles and copper 8-hydroxyquinolinate is preferably 1:5-
5：1.
Further, Synergistic bactericidal composition of the invention is removed outside active component, also comprising in Pesticide formulation
Conventional auxiliary agent and/or carrier.
Further, the auxiliary agent can be conventional surfactant, such as emulsifying agent, dispersant, wetting agent, infiltration
Agent, can also other conventional auxiliary elements such as thickener, defoamer, antifreezing agent, stabilizer, one kind in PH conditioning agents or one
More than kind.
Further, the weight percentage of composition shared by active component is 1- in Synergistic bactericidal composition of the invention
70%, preferably 10-60%.
Further, Synergistic bactericidal composition of the invention can pass through the conventional auxiliary element system in Pesticide formulation
It is standby into any one formulation for being adapted to agriculturally use, including but not limited to missible oil, wettable powder, water dispersible granules, water and milk
Agent, microemulsion, suspending agent etc..
Further, Synergistic bactericidal composition of the invention can be provided in finished product preparation form, i.e., each in composition
Material is blended, can also be provided in the form of single dose, is directly mixed using preceding in tank or bucket, required for being then diluted to
Concentration.
Further, other agricultural active compositions can be also contained in composition pesticide of the invention.
Compared with prior art, Synergistic bactericidal composition of the invention has the beneficial effect that：1st, Bactericidal composite of the invention
The active component mechanism of action is different in thing, and both compounding uses can reduce or delay the drug-fast generation of pathogen；2、
Interaction in the bactericidal composition of the present invention between active component is not simple superposition, but can be played between the two
Synergistic function, it is possible to reduce pesticide activity component usage amount, improves prevention effect；3rd, prepared by bactericidal composition of the invention
Technique is simple, prevention effect is good, Environmental compatibility is good.
Embodiment
In order that the objects, technical solutions and advantages of the present invention more brief introduction understands, present invention specific examples below
Illustrate, but the present invention is only limitted to absolutely not these examples, and as described below is only the present invention preferably embodiment, is used only for retouching
State the present invention, it is impossible to be interpreted as limiting the scope of the present invention, it is noted that it is all the spirit and principles in the present invention it
