Abstract
The invention discloses a kind of bactericidal composition containing flutianil, active ingredient is made of A and B, and A flutianil, B are any one in Fluoxastrobin, pyraclostrobin and trifloxystrobin, and the mass ratio of A and B are 1 ︰, 50~50 ︰ 1.The composition synergistic effect is apparent, and preventive effect is high, is suitable for preventing the multiple diseases on gourd, fruit and vegetable, is particularly suitable for preventing powdery mildew.
Description
Technical field
The present invention relates to a kind of bactericidal composition more particularly to one kind with flutianil Bactericidal composites as main component
Object and its application for preventing corps diseases, belong to technical field of pesticide.
Background technology
Powdery mildew is the plant disease as caused by the Erysiphaceae (Erysiphacesae) in fungi.Such as：By standing grain white powder
Cereal powdery mildew caused by bacterium (Ery-siphe graminis)；By Siberian cocklebur monofilament shell (Sphaerotheca fuliginea)
The powdery mildew of the various plants such as caused melon, beans, crudefiber crop；It is careless as caused by strawberry snag shell (Uncinula necator)
Certain kind of berries powdery mildew；Mulberry, pears, persimmon, walnut, chestnut, lichee, papaya etc. as caused by hazel ball pin shell (Phyllactinia corylea)
The powdery mildew of more than 80 kinds of trees；The powdery mildew of Flowers of Rosa as caused by rose monofilament shell (Sphaerotheca pannosa)
Deng.
In the prevention of powdery mildew, benzimidazole, triazole bactericidal agent are relied primarily at present.These medicaments are because long-term
Using different degrees of drug resistance has been produced, control effect reduces.In addition, triazole type medicament when dosage is big to crop
Growth has inhibiting effect, easily causes poisoning.
Flutianil be thiazolidines fungicide, molecular formula：C19H14F4N20S2, molecular weight 426.5.The medicament passes through suppression
The mycelia of pathogen processed grows and takes effect.Flutianil is in extremely low concentration (10mg/L) to diseases such as the powdery mildews of gourd, fruit and vegetable
The tall and erect effect of evil tool.
For flutianil as a kind of new type bactericide, current production and application cost is higher, and individually makes for a long time
With also there is very big resistance risk.
Invention content
The object of the present invention is to provide a kind of synergistic effect is apparent, good, the at low cost, resistance risk to powdery mildew control effect
Low bactericidal composition.
It is a further object of the present invention to provide the applications of the bactericidal composition.
Inventor has been surprisingly found that flutianil and Fluoxastrobin or pyrrole by a large amount of indoor biometrics and field control effectiveness test
Azoles kresoxim-methyl or trifloxystrobin after mixture, have significant synergistic effect to diseases such as powdery mildews in certain proportion.
The Fluoxastrobin (azoxystrobin)：Strobilurin fungicide, molecular formula C22H17N3O5.Efficiently, extensively
Spectrum, to almost all of mycota (Ascomycotina, Basidiomycotina, Mastigomycotina and Deuteromycotina) disease such as white powder
Disease, rust, glume blight, net blotch, downy mildew, late blight, epidemic disease, rice blast etc. have good activity.It is sprayed available for cauline leaf
Mist, seed treatment can also carry out soil treatment, be mainly used for cereal, rice, peanut, grape, potato, fruit tree, vegetables, coffee
Coffee, lawn etc..The mechanism of action destroys the energy synthesis of germ, tool protection is treated and rooted out to inhibit sick fungal mitochondria breathing
Triple function.
The pyraclostrobin (pyraclostrobin)：Strobilurin fungicide, molecular formula C19H18ClN3O4。
Wide-spectrum bactericide has protection, treatment, blade infiltration conduction.For mitochondrial respiratory inhibitor.Pyraclostrobin is to cucumber
Powdery mildew, downy mildew and banana freckle, leaf spot, the late blight of potato, downy mildew of garpe etc. have very good effect.
The trifloxystrobin (trifloxystrobin)：Strobilurin fungicide, molecular formula C20H19F3N2O4.Tool
Have efficiently, wide spectrum, protection, treat, root out, permeating, systemic activity, resistance of rainwater washing against, the lasting period length etc. characteristics.Except to white powder
Disease, leaf spot have outside special efficacy, have good work to rust, downy mildew, late blight, damping-off, scab of apple, sclerotinia sclerotiorum
Property.
Fluoxastrobin, pyraclostrobin, trifloxystrobin are strobilurin fungicides well known in the art, can be by each

Specific embodiment
The present composition has apparent synergistic function to Powdery Mildew etc., rather than just two kinds of pharmacy effects
Simple addition, this can from following toxicity test test result in be clear that.
Bioassay example 1：Composition tests the Toxicity Determination of cucurbits powdery mildew bacterium
Subjects are cucumber powdery mildew's pathogen (Sphaerotheca fuliginea).
Test method：Reference《People's Republic of China (PRC) agricultural industry criteria NY/T 1156.11-2008》.Choose growth potential
Consistent potting two panels leaf period cucumber seedling, is sprayed with Potter spray towers under 50PSI pressure, per basin 5mL.Each medicament is set
Put 5 concentration gradients.It is 3 × 10 to carry out inoculum density afterwards for 24 hours5The cucumber powdery mildew's pathogen conidial suspension of a spore/mL.
To spray the cucumber seedling of equivalent clear water as blank control.Cucumber seedling is put into greenhouse after inoculation and is cultivated.After 10d, according to cucumber
The morbidity grade scale investigation disease index of powdery mildew, and calculate control effect.
Powdery mildew of cucumber severity Scaling standard：
0 grade：Blade disease-free spot；
1 grade：Lesion area accounts for the area of entire blade below 5%；
3 grades：Lesion area accounts for the 6%~10% of the area of entire blade；
5 grades：Lesion area accounts for the 11%~25% of entire blade area；
7 grades：Lesion area accounts for the 25%~50% of entire blade area；
9 grades：Lesion area accounts for more than 50% entire blade area.
The expection effect (i.e. theoretical control effect, %) of mixture of active principles determined using Colby formula and with observation
To effect compare：
Colby formula：E=X+Y-X*Y/100
E：When active components A uses a concentration of a, active constituent B that compositions contemplated during a concentration of b is used to imitate in composition
Power.
X：Effect when active components A dosage is a.
Y：Effect when active constituent B dosages are b.
Illustrate that mixture has synergistic effect when the practical control effect observed is more than expected preventive effect.
Toxicity test result is referring to table 1 to table 3.
1 flutianil of table is with azoxystrobin compound to the pot experiment measurement result of cucumber powdery mildew's pathogen
2 flutianil of table compounds the pot experiment measurement result to cucumber powdery mildew's pathogen with pyraclostrobin
3 flutianil of table compounds the pot experiment measurement result to cucumber powdery mildew's pathogen with trifloxystrobin
It is anti-that result of the test shows that flutianil is compounded in a certain range with Fluoxastrobin or pyraclostrobin or trifloxystrobin
Cucumber powdery mildew's pathogen is controlled, there is synergistic effect.
In order to make the purpose , technical scheme and advantage of the present invention be clearer, the present invention is real with preparation in detail below
Example illustrates, but the present invention is limited to absolutely not these examples.As described below is only the preferable embodiment of the present invention, is only used to solve
