Abstract
The invention discloses a kind of pyrrole bacterium benzene prestige bactericidal compositions, are made of active ingredient pyrrole bacterium benzene prestige and dithianon, and the mass ratio of the two is 1 ︰, 50~50 ︰ 1.The composition synergistic effect is apparent, and preventive effect is high, is suitable for preventing the multiple diseases on fruit and vegetable crops, be particularly suitable for preventing apple, citrus, strawberry, it is melon on anthracnose.
Description
Technical field
The present invention relates to a kind of bactericidal composition more particularly to one kind with pyrrole bacterium benzene prestige bactericidal composition as main component
And its application of prevention corps diseases, belong to technical field of pesticide.
Background technology
Apple anthracnose is also known as bitter rot, late blight, is one of fruit disease important on apple, China's major part apple
There is generation in producing region, is particularly acute in summer high temperature, rainy, humid region morbidity.The disease main harm fruit, can also endanger
Branch and fruit platform etc..Anthrax bacteria can infect fruit from young fruit period to the maturity period.Morbidity at the beginning of general 6 months, 7~August are peak period,
With the maturation of fruit, hole skin suberification degree improves, and infects reduction.
Apple anthracnose is mainly using preventions such as Prochloraz, Mancozeb, thiram, triazole type medicaments at present.These medicines
Because chronic administration, germ resistance rise, control effect is in downward trend year by year for agent.
Pyrrole bacterium benzene prestige (pyribencarb), molecular formula C18H20ClN3O3, molecular weight 361.8 is Benzylcarbamate knot
The new type bactericide of structure.The fungicide hinders pathogen spore by destroying the electron transport system of pathogen cell Mitochondria
Son is sprouted and is played a role after preventing spore-germination to infecting for host.The fungicide to the gray mold of crops, ring spot,
The multiple diseases such as sclerotiniose, anthracnose, scab, spot defoliation, rice blast have good effect.
But pyrrole bacterium benzene prestige it is current production and application cost it is higher, and be used alone also have very big resistance for a long time
Risk.
Pyrrole bacterium benzene prestige with the pesticide active ingredient of other structures is combined and is compounded, is solved in its single dose application process
A kind of effective mode of cost and resistance problem.After the pesticide active ingredient mixing of different structure, three kinds of works are typically exhibited
With type, i.e. summation action, synergistic effect and antagonism.Compound synergic is formulated well, can improve practical control effect, drop
The usage amount of low pesticide additionally aids the generation for delaying germ drug resistance, is the important means of integrated control.
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 sheath blight disease controlling effect
Low bactericidal composition.
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 apparent synergistic function to apple anthrax bacteria, makees rather than just two kinds of medicaments
Simple addition, this can test in the result with field control effectiveness test from following Toxicity Determination and be clear that.
Bioassay example 1：Composition tests the Toxicity Determination of apple anthrax bacteria
Subjects are apple anthrax bacteria (Colletotrichum gloeosporioides).
Experiment is using mycelial growth rate method.The experiment liquid that 5ml is prepared is taken to be 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, each handle 4 repetitions, horizontal rest, after cooling tablet.With diameter 5mm card punch from culture 5d
Cut bacteria cake for examination bacterium edge, with needle is chosen by being connected on one side on the malicious culture medium of band with mycelia, all operations are ultra-clean
Workbench carries out sterile working.Tablet 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 niqueMin (y), liquor strength (μ g/ml) is converted into logarithm (x), with minimum
Concentration EC during square law calculates virulence equation and inhibits50, according to the toxicity index and co-toxicity coefficient of the abundant method calculating medicaments of Sun Yun
(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 actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100
Evaluation criterion：CTC≤80 are antagonism, and 80 ＜ CTC ＜ 120 are summation action, and CTC >=120 are synergistic effect.
Result of the test can be seen that pyrrole bacterium benzene prestige and 50~50 ︰ of dithianon 1 ︰ in mass ratio, 1 mixtures from table 1, to apple
Fruit anthrax bacteria has synergistic effect, and when especially matching between 1 ︰, 30~30 ︰ 1, synergy is more notable, and co-toxicity coefficient exists
More than 170.
1 pyrrole bacterium benzene prestige of table is with dithianon mixture to the Toxicity Determination result of the test of apple anthrax bacteria

It tests and is carried out in Shandong Yantai apple proving ground.The plot anthracnose occurs throughout the year.Apply first within 15 days after fallen flowers
Secondary medicine (morbidity is had no before medicine), applied a medicine, medication 3 times after ten days.4 repetitions of each chemicals treatment.Investigation method:By pair
5 plants of apple trees are fixed in linea angulata sampling, every plant of tree middle part by East, West, South, North, in investigate 10 fruits, morbidity number is recorded in classification,
Calculate incidence and disease index
Fruit classification standard：
0 grade：Disease-free spot；
1 grade：Lesion area accounts for less than 1% fruit area；
2 grades：Lesion area accounts for the 1~3% of fruit area；
3 grades：Lesion area accounts for the 3~5% of fruit area；
4 grades：Lesion area accounts for more than 5% fruit area.
As a result with analysis
It can be seen that by result of the test in table 2：Pyrrole bacterium benzene prestige, dithianon single dose are respectively to the preventive effect of apple anthracnose
77.0% and 71.5%, and bactericidal composition of the embodiment of the present invention is significantly increased in preventive effect, minimum preventive effect is 87.9%,
Up to 93.3%.The result of field trial has apple anthracnose after fully showing pyrrole bacterium benzene prestige and dithianon compounding
Significant synergistic function, in the case where effective ingredient consumption is reduced than single dose, control effect greatly improves.Therefore, originally
Inventive composition has the function of to reduce cost, reduces spraying times and pesticide residue, delaying drug resistance.
