Abstract
The invention discloses a kind of bactericidal compositions, are made of effective component fluorine azoles bacterium acyl azanol and benziothiazolinone, and the mass ratio of the two is 1 ︰, 70~70 ︰ 1.The composition synergistic effect is obvious, and preventive effect is high, is suitable for preventing and treating the multiple diseases on crop, is particularly suitable for preventing and treating head blight, anthracnose, spot defoliation.
Description
Technical field
The present invention relates to a kind of bactericidal composition more particularly to a kind of bactericidal composition containing fluorine azoles bacterium acyl azanol and its
The application for preventing and treating corps diseases, belongs to technical field of pesticide.
Background technique
The wheat scab alias wheat head is withered, rotten wheat head, red wheat head, is one of Major Diseases of wheat.Wheat scab exists
The whole world generally occurs, and is distributed mainly on moist and half tide wet zone, and it is aggrieved serious to moisten rainy Temperate Region in China for especially weather.
All can be aggrieved from seedling to heading, mainly cause withered seedling, brown foot rot, stalk rotten and fringe corruption, the most serious is fringe corruption wherein causing harm.
Citrus anthracnose is the most common disease of citrus, it has the characteristics that harm is wide and harm time is long, main harm
Blade, branch, flower, fruit and carpopodium, often result in tangerine and orange class etc. Citrus Cultivars largely fallen leaves, branch is withered, a large amount of fallen flowers,
Shedding and fruit rot.
Alternaria leaf spot of apple is also known as Phomopisis vexans, main harm blade, causes caducous, also endangers young sprout and fruit, influences
Tree vigo(u)r and yield have generation in each apple producing region, aggrieved heavier with Bohai Sea Gulf and ancient riverbed of the Yellow River area.Pathogen is
Alternaria alternaria f.sp mali (rod method apple specialized form) belongs to Deuteromycotina fungi.
Fluorine azoles bacterium acyl azanol is novel pyrazole acid amide fungicides, molecular formula C16H16Cl3F2N3O2.Fluorine azoles bacterium acyl azanol
Belong to succinate dehydrogenase inhibitors (SDHI) class, is pyrazoles -4- amides compound, structure novel, activity are high, fungicide is composed
Extensively.
Fluorine azoles bacterium acyl azanol has favorable effect to above-mentioned disease.But the current production and use of fluorine azoles bacterium acyl azanol at
This is higher, and is used alone also for a long time and has very big resistance risk.
It combines fluorine azoles bacterium acyl azanol with the pesticide active ingredient of other structures and compounds, be to solve its single dose to apply
A kind of effective mode of cost and resistance problem in journey.After the pesticide active ingredient mixing of different structure, three are typically exhibited
Kind type of action, i.e. summation action, synergistic effect and antagonism.Compound synergic is formulated well, can improve practical prevention and treatment effect
Fruit reduces the usage amount of pesticide, additionally aids the generation for delaying germ drug resistance, is the important means of integrated control.
Summary of the invention
The object of the present invention is to provide a kind of synergistic effect is obvious, resistance wind good, at low cost to above-mentioned disease-controlling effect
The low bactericidal composition in danger.
It is a further object of the present invention to provide the applications of the bactericidal composition.
In order to overcome the deficiencies of the prior art, the technical scheme is that in this way solving：A kind of bactericidal composition, contains

Specific embodiment
The present composition has obvious synergistic function head blight, gray mold, spot defoliation, and not only
It is the simple addition of two kinds of pharmacy effects, this can be from the result of following indoor toxicity determination test and field control effectiveness test very
It can be clearly seen.
Bioassay example 1：Indoor toxicity determination test of the composition to fusarium graminearum
Subjects are fusarium graminearum (Gibberella zeae)
Test uses mycelial growth rate method.The experiment medical fluid for taking 5ml to prepare is added to equipped with the hot culture medium (PDA of 45ml
Culture medium, 45-50 DEG C) conical flask in, after shaking up, pour into diameter 90mm glass culture dish rapidly, each culture dish pours into band
Medicine culture medium 12ml, 4 repetitions of each processing, horizontal rest, it is cooling after plate.With diameter 5mm punch from culture 5d
Cut bacteria cake for examination bacterium edge, with needle is chosen by be connected on the malicious culture medium of band on one side with mycelia, all operations are ultra-clean
Workbench carries out sterile working.Plate is placed in 25 DEG C of constant temperature sterile culture case after processing and is cultivated, is handed over after 5d using cross
Fork method measures the colony diameter of each processing respectively, calculates the average net growth of the average value, colony diameter of each processing colony diameter
Amount and mycelial growth inhibition rate.
Net growth (mm)=measurement colony diameter -5
Mycelial growth inhibition rate (%)=[(control group net growth-processing group net growth)/control group net growth]
×100
Mycelial growth inhibition rate is converted into probability value (y), liquor strength (μ g/ml) is converted into logarithm (x), with minimum
Square law calculates concentration EC in virulence equation and inhibition50, the toxicity index and co-toxicity coefficient of medicament are calculated according to Sun Yunpei's Method
(CTC)。
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50)×100
Percentage composition+B the medicament toxicity index of A in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
The percentage composition of B in agent
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] × 100
Evaluation criterion：CTC≤80 are antagonism, and 80 < CTC < 120 are summation action, and CTC >=120 are synergistic effect.
As it can be seen from table 11 mixture of fluorine azoles bacterium acyl azanol and 70~70 ︰ of benziothiazolinone 1 ︰ in mass ratio, to wheat scab
Bacterium has synergistic effect, and when especially proportion is between 1 ︰, 50~50 ︰ 1, synergy is more significant, and co-toxicity coefficient is 170 or more.
1 fluorine azoles bacterium acyl azanol of table is with benziothiazolinone mixture to the The Toxicity Determination result of fusarium graminearum
Bioassay example 2：Indoor toxicity determination test of the composition to citrus anthracnose bacterium
Subjects are citrus anthracnose bacterium (Colletotrichum gloeosporioides)
Test method and evaluation method are the same as fusarium graminearum indoor toxicity test method.
From table 2 it can be seen that 1 mixture of fluorine azoles bacterium acyl azanol and 70~70 ︰ of benziothiazolinone 1 ︰ in mass ratio, to citrus anthracnose
Bacterium has synergistic effect, and when especially proportion is between 1 ︰, 50~50 ︰ 1, synergy is more significant, and co-toxicity coefficient is 170 or more.
2 fluorine azoles bacterium acyl azanol of table and benziothiazolinone mixture are to citrus anthracnose bacterium The Toxicity Determination result
Bioassay example 3：Indoor toxicity determination test of the composition to Alternaria mali
Subjects are Alternaria mali (Alternaria alternaria f.sp mali)
Test method and evaluation method are the same as bioassay example 1.
From table 3 it can be seen that 1 mixture of fluorine azoles bacterium acyl azanol and 70~70 ︰ of benziothiazolinone 1 ︰ in mass ratio, falls apple spot
Leaf disease bacterium has a synergistic effect, and when especially proportion is between 1 ︰, 50~50 ︰ 1, synergy is more significant, co-toxicity coefficient 170 with
On.
3 fluorine azoles bacterium acyl azanol of table and benziothiazolinone mixture are to Alternaria mali The Toxicity Determination result
In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention is real with preparation in detail below
Example is illustrated, but the present invention is limited to absolutely not these examples.The following is only the preferred embodiment of the present invention, is only used to solve
