Abstract
The invention relates to a pesticide composition containing benzothiostrobin and fluopyram. The ratio of benzothiostrobin to fluopyram in parts by weight is (1:30) to (30:1), and the balance is a pesticide adjuvant. The pesticide composition has a relatively good synergetic effect on prevention and treatment of powdery mildew of cucumber within a ratio range, and is beneficial to reduction of the usage amount of an active component of the pesticide and reduction of the medication cost.
Description
Technical field
The invention belongs to composition pesticide field, and in particular to be a kind of agriculture comprising benzothiostrobin and fluopyram
Drug composition and its with use.
Background technology
Powdery mildew of cucumber is commonly called as " white hair disease ", aggrieved most heavy with blade, next to that petiole and stem, typically do not endanger fruit.
Their early stage, face of blade or the back side produce the rotund little amyloid plaque of white, are gradually expanded into the unconspicuous large stretch of white lead in edge
Area, is covered with blade face, as having spread layer white lead.Erase white lead, it is seen that blade face chlorisis, it is withered and yellow to become fragile.When falling ill serious, blade face is covered with
White lead, becomes canescence, until whole blade is withered.Powdery mildew is infected after petiole and tender stem, symptom to it is similar on blade, only
Scab is less, and powder is also few.Start to produce yellow point on blade, then expand and develop circular or oval scab,
There is the mould layer of white powder on surface.Ordinary circumstance bottom blade is more than upper blade, and vacuum side of blade is more than front.Mildew early stage is single
Solely dispersion, after be unified into a big mildew, it might even be possible to cover full leaf, have a strong impact on photosynthesis, receive eubolism
To interference, senilism, yield is caused to incur loss.
Benzothiostrobin is the innovation antibacterial candidate variety with independent intellectual property right, can be widely used for preventing and treating vegetable and melon
Fruit powdery mildew, downy mildew, gray mold, brown spot, scab, corn southern leaf blight, rice green smut, Citrus ground maize ear rot, Brassica campestris L
Sclerotiniose etc..The methoxy acrylic bactericide mechanisms of action such as benzothiostrobin and Fluoxastrobin are identical, are mitochondrial respiratory chain
Cytochrome b c1 complex inhibitors, there is good safety to beneficial organism and crop, low toxicity and environmentally friendly.Repeatedly
Field control effectiveness test shows：Benzothiostrobin can be used for preventing and treating the preventing and treating of multiple diseases, particularly to powdery mildew of cucumber and Fructus Cucumidis sativi
Downy mildew shows excellent preventive effect, and its preventive effect is better than or suitable with import antibacterial Fluoxastrobin, but active compound cost, mu medication
Cost is below Fluoxastrobin.
Fluopyram is the new pyridine base ethyl benzamide series bactericidal agent of Beyer Co., Ltd's exploitation, by hindering breathing
The electron transfer of succinate dehydrogenase in chain and suppress mitochondrial respiratory, fluopyram can be used for prevent and treat 70 various crops on
Disease research, it is especially excellent to sclerotinite, ash arrhizus bacteria, Monilia pathogenic bacteria and the microbial diseases control of powdery mildew.
At present, the relevant report that benzothiostrobin and fluopyram are compounded not yet is found.
The content of the invention
Present invention aims to the deficiencies in the prior art, there is provided a kind of collaboration increasing for having treatment and protective effect concurrently
Effect compositionss, the composition for preventing and controlling effect is good, wide sterilization spectrum.
Another object of the present invention is to provide the application of the bactericidal composition, the bactericidal composition can be answered extensively
For preventing and treating multiple diseases, such as powdery mildew, downy mildew, gray mold, brown spot, scab, corn southern leaf blight, rice green smut,
Citrus ground maize ear rot, sclerotinia rot of colza.
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that：
A kind of composition pesticide, it is characterised in that active component includes benzothiostrobin and fluopyram, wherein, benzothiostrobin
It is 1 with the weight ratio of fluopyram:30-20:1.
Further, the weight ratio of benzothiostrobin and fluopyram is 1:20-10：1.
Further, the weight ratio in the composition pesticide shared by active component is 1-80%, preferably 20-50%.
Further, the content of active component depends on amount of application when being used alone in compositionss of the invention, also takes
Certainly in a kind of compound and the mixed ratio and potentiation degree of another kind of compound, while also relevant with target disease.
Further, conventional auxiliary element is processed into during bactericidal composition of the invention is by being aided with Pesticide formulation
Any one dosage form can be for example cream, wettable powder, dispersible oil-suspending agent, suspending agent, water dispersible granules, water and milk
Agent, microemulsion, granule etc..
The compositionss of the present invention can be that each material is blended in compositionss with finished product preparation form offer, it is also possible to
Unit dose form is provided, and is directly mixed in proportion in bucket or tank using front, is then diluted to required concentration.
Further, compositionss of the invention can also add other agricultural active compositions, for example antibacterial, insecticide,
The agricultural active composition such as herbicide, fertilizer.
Compared with prior art, of the invention composition pesticide has the beneficial effect that：
1st, the composition pesticide containing benzothiostrobin and fluopyram of the invention is in the ratio range, to various plants
Disease has obvious potentiation, it is possible to reduce the usage amount of pesticide activity component, improves prevention effect.
2nd, active component benzothiostrobin and the fluopyram mechanism of action are different in composition pesticide of the invention, can
To overcome or delay the drug-fast generation of pathogen.
3rd, composition pesticide of the invention can expand antimicrobial spectrum by mutually compounding, reduce spraying times.

2nd, indoor bioassay
Subjects：Cucumber powdery mildew's pathogen
Test method：Test refers to People's Republic of China (PRC) industry standard NY/T 1156.11-2008《Farm-chemical indoor determination
The part of test rule antibacterial the 11st：Preventing and treating cucurbits powdery mildew test pot-culture method》, determined using pot-culture method.
Sow susceptible cucumber variety, potted plant to grow to 2 leaf periods standby.Benzothiostrobin and fluopyram 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 medicinal liquids are uniformly sprayed on blade face to whole moistenings, treat that medicinal liquid dries naturally standby.And set containing only solvent and surfactant
And blank is made in the process for not containing effective ingredient.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 in spore, and double gauze is filtered, and 1 × 10 is modulated into after microscopy5The suspension of individual/mL.It is placed in after inoculation in thermostatic chamber,
Cultivate 7 days under the conditions of 24 DEG C of temperature.When blank sickness rate reaches more than 80%, incidence is managed everywhere in classification investigation,
Calculate the disease index and prevention effect of each process.
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, according to the abundant methods of Sun Yun the toxicity index and co-toxicity coefficient of medicament are calculated（CTC）.Test knot
Fruit is shown in Table 1.
