Description
Technical field
The present invention relates to composition pesticide field, and in particular to be a kind of comprising pyraclostrobin and Physcion
Pesticide sterilizing composite.
Background technology
It is the maximally efficient means for preventing and treating fungal diseases of plants using chemical agent.But long-term continuous high dose ground is applied
Single chemical bactericide, the problems such as residual, environmental pollution and the resistance to resistance to the action of a drug fungi for easily causing medicament are developed.Reasonably
Chemical bactericide is compounded or mixture has expansion fungicidal spectrum, is improved prevention effect, extension optimum period for applying fertilizer, is reduced dosage, reduces
Poisoning, reduction residual, delay Antifungal resistance and drug-fast generation and the positive feature such as development, bactericide compounded or mixture are
One of maximally efficient method for solving the above problems.Develop new product bactericide price constantly rises, and by contrast, exploitation with
Research efficiently, the compounding of low toxicity, low-residual with mixture has small investment, the lead time is short and paid attention to both at home and abroad, one after another add
Dynamics is developed in great development.
Pyraclostrobin is the bactericide of BASF AG's latest model methoxy acrylic.Sterling is white to shallow rice
Color tasteless crystalline solid.The mechanism of action is mitochondrial respiratory inhibitor.Prevent mitochondria from producing and providing cell eubolism institute
Energy is needed, cell death is ultimately resulted in.It can control most of diseases such as Ascomycetes, Basidiomycetes, deuteromycetes, Oomycete
Evil.There is very strong inhibitory action to the growth of spore germination and leaf intramatrical mycelium, with protection and therapeutic activity.With permeability
And local systemic activity, the lasting period is long, resistance of rainwater washing against.It is widely used in preventing and treating wheat, paddy rice, peanut, grape, vegetables, horse
Disease on bell potato, banana, lemon, coffee, fruit tree, walnut, tea tree, tobacco and ornamental plant, lawn and other field crops.
Not only toxicity is low for the compound, to non-target organism safety and friendly to user and environment safety, by U.S. EPA
It is classified as " Candidate Agents for reducing risk ".In addition, pyraclostrobin can produce positive physiological regulatory action to crop, it can press down
The generation of ethene processed, can so help crop to have the longer time to lay in bio-energy ensures maturity；Work can be significantly improved
The activity of the nitrification reductase of thing, it is meant that the use of Nitrogen In Soils fertilizer can be reduced, so as to further reduce to underground water
Influence；When crop is subject to viral attack, it can accelerate to resist the formation of albumen --- with crop itself salicylic acid synthetic pair
The synthesis of degeneration-resistant albumen is identical.Pyraclostrobin is that the efficient mitochondrial respiratory after being improved on the basis of kresoxim-methyl suppresses
Agent, is that the o-methyl-phenyl in kresoxim-methyl molecular structure is substituted for N- rubigan pyrazolyls, and the another methoxyl group developed
Esters of acrylic acid wide-spectrum bactericide, its activity is higher, is 3 times at present with series bactericidal agent.Powdery mildew is prevented at present at home
Effect has declined.
Physcion, alias physcion, physcion, Physcion are one
Highly active vegetable source bactericide is planted, with natural plants rheum officinale as raw material, through extracting its active component meticulously, processing is developed,
There is good prevention effect to powdery mildew, downy mildew, gray mold, anthracnose etc..It is environmentally friendly to people and animals' low toxicity, especially fit
Together in green and organic vegetable production.Physcion is protective fungicide, and induction crop produces defense reaction, suppresses cause of disease
Bacterium spore germination, the growth of mycelia, the formation of haustorium so that crop reaches the effect of diseases prevention from the infringement of pathogen.
Applicant of the present invention is furtherd investigate by the recipe determination to pyraclostrobin and Physcion, is found
To there is obvious synergy to various plants disease fungus in certain scope after pyraclostrobin and Physcion compounding
Effect, completes the present invention after further research.At present, there is no what is compounded on pyraclostrobin and Physcion
Relevant report.
The content of the invention
It is an object of the invention to provide a kind of synergy fungicide for being adapted to and agriculturally using, help to reduce Pesticide use
Amount, delays the drug-fast generation of pathogen and reduces use cost.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：A kind of Synergistic bactericidal composition, its feature exists
In, active component includes pyraclostrobin and Physcion, wherein, the weight ratio of pyraclostrobin and Physcion is 1:
30-40：1, preferably 1:10-30：1.
Further, the weight percentage of active component is 1-90%, preferably 20-50% in the bactericidal composition.
Further, the bactericidal composition can be processed into agricultural by preparation method conventional in Pesticide formulation
Any formulation of upper permission, for example can be wettable powder, water dispersible granules, aqueous emulsion, microemulsion, suspending agent, micro-capsule hang
Floating agent.
The composition of invention can be that each material is blended in composition with finished product preparation form offer, it is also possible to list
Dosage form formula is provided, and is directly mixed in proportion in bucket or tank using preceding, is then diluted to required concentration.
Further, composition of the invention can also add other agricultural active compositions, for example bactericide, insecticide,
The agricultural active composition such as herbicide, fertilizer.
Bactericidal composition of the invention is applied to prevents and kill off various diseases such as powdery mildew of cucumber, tomato powdery mildew, powdery mildew of strawberry
Evil.
Compared with prior art, composition pesticide of the invention has the beneficial effect that：
（1）After composition compounding of the invention, there is obvious synergistic function, preventive effect and single work in certain scope
Property composition compared to being significantly improved；
（2）The active component mechanism of action is different in composition of the invention, while effectively crop disease is prevented and treated, can be with
Delay the drug-fast generation of pathogen, be conducive to delaying the service life of pesticide activity component；
（3）Composition preparation process is simple of the invention, is adapted to popularization and application in actual production.

Determine the part of test rule bactericide the 11st：Preventing and treating cucurbits powdery mildew experiment pot-culture method》, determined using pot-culture method.
Sow susceptible cucumber variety, potted plant to grow to 2 leaf periods standby.Pyraclostrobin and Physcion active compound point
Do not dissolved with dimethylformamide, then dissolved with 0.1% Tween-80 aqueous surfactant solution.3 basins are often processed, 4 repetitions will
10 mL liquids are uniformly sprayed on blade face to whole wettings, treat that liquid dries naturally standby.And set containing only solvent and surfactant
And blank is made in the treatment for not containing effect composition.24 h after chemicals treatment, spray inoculation cucumber powdery mildew's pathogen spore suspension.
The process for preparation of spore suspension is as follows：Take and cover with Powdery Mildew blade, with the aseptic of a small amount of Tween-80 surfactant of refueling
Water washes down spore, double gauze filtering, and 1 × 10 is modulated into after microscopy5The suspension of individual/mL.It is placed in thermostatic chamber after inoculation,
Cultivated 7 days under the conditions of 24 DEG C of temperature.When blank disease liquid rate reaches more than 80%, incidence is managed in classification investigation everywhere,
Calculate the disease index and prevention effect of each treatment.
Prevention effect is converted into probit value（y）, liquor strength（ug/mL）It is converted into logarithm value（x）, by minimum in terms of multiplication
Concentration EC in calculating virulence equation and suppressing50, the toxicity index and co-toxicity coefficient of medicament are calculated according to the abundant methods of Sun Yun（CTC）.Experiment knot
Fruit is shown in Table 1.
