Description
Technical field
The invention belongs to agricultural disease Prevention Technique fields, and in particular to a kind of containing chlorine fluorine ether bacterium azoles and Ningnanmycin kill
Bacteria composition.
Background technique
Fluorine chlorine ether bacterium azoles (English common name mefentrifluconazole), a kind of wide spectrum, efficiently, interior suction triazole type kills
Microbial inoculum, and belong to sterol demethylation inhibitor class, the mechanism of action is to prevent the biosynthesis of ergosterol, inhibits cell raw
Grow and eventually lead to the collapsing of cell membrane.
The unique isopropyl alcohol groups of fluorine chlorine ether bacterium azoles can be rotated freely extremely flexibly and target knot from free state
Reference state is synthesized, flexible and changeable spatial shape remains fluorine chlorine ether bacterium azoles efficiently to multiple resistance bacterial strain, many
Refractory fungal disease has outstanding bioactivity,.Currently used for field crops many in world wide and special crop, such as
On corn, cereal, soybean and industrial crops.
Ningnanmycin is isolated in Ningnan County, Sichuan Province soil, and the Cystosine nucleocide type to find for the first time newly resists
Raw element, therefore its tunning is named as Ningnanmycin.At present tobacco mosaic virus disease, tomato virus disease, pepper virus disease,
Rice seedling blight, stripe disease, alternaria leaf spot of apple, achieves registration in powdery mildew of cucumber at root rot, this
External prevention and treatment sclerotinia sclerotiorum, peronophythora litchi, the multiple diseases such as other crop virosis, stem rot, blight dis-ease, powdery mildew
On be also widely applied.
It is fungus-caused to be applied to the Basidiomycetes such as banded sclerotial blight since large area in recent years uses on rice for Ningnanmycin
Disease control, but for resistance than heavier, preventive effect decline is serious, and same medicament is used for a long time now, is unfavorable for entire ecological ring
The protection in border；Fluorine chlorine ether bacterium azoles is a kind of completely new mechanism of action triazole bactericidal agent, we innovatively by two kinds of fungicide into
Row is used in compounding, and is tested the formulations Comparative of the two different ratio, different dosage forms, by nearly 2 years field screening tests,
It was found that the preventive effect to banded sclerotial blight can be significantly improved, the drug cost of peasant household is reduced, banded sclerotial blight is delayed to prolong the resistance of Ningnanmycin
Long Ningnanmycin service life, has a vast market and application prospect.

(2), the embodiment of indoor biological activity assay
1, fluorine chlorine ether bacterium azoles compounds the indoor toxicity determination test to rice sheath blight disease with Ningnanmycin
The measurement of mycelia block method is connect using Potted orchard.Fluorine chlorine ether bacterium azoles and Ningnanmycin raw medicine, with appropriate dimethylformamide
Dissolution, is configured to the mother liquor of 10000mg/L, is placed in spare in 4 DEG C of refrigerators.Fluorine chlorine ether bacterium azoles and Ningnanmycin weight proportion 1:
10、1∶20、1∶30、1∶50、1∶60、1∶1、1∶2、1∶3、1∶5、2∶3、5∶7、2∶1、3∶8、10∶1、20∶1、30∶1、50∶1、60
: 1 and each single dose totally 20 kinds of chemicals treatments, mass concentration gradient are set as 5 gradients 0.125,0.25,0.5,0.75,1mg/L,
Each mass concentration sets 3 repetitions.Separately clear water is set as blank control.The consistent potting rice seedling of 3 leaf, 1 heart, growing way is selected, it is spraying to locate
Naturally dry after reason, left and right is inoculated with for 24 hours, in the every basin rice seedling base portion center one piece of banded sclerotial blight mycelia of clamping connection for being jetted through medicine
Block, fungus block not contacted with basin soil and water layer.Test material is moved in humidistat and is cultivated after inoculation, and 26 DEG C of temperature, humidity 80%~
90%, rice growth situation, investigation result when waiting blank controls sufficiently to fall ill after 5d are observed daily, and grade scale uses field medicine
It imitates test rule to carry out, each processing preventive effect is calculated with disease index, carries out data analysis statistical with SPSS16.0 version software,
Find out virulence regression equation, EC50Value, related coefficient.According to Sun Yunpei's Method measure co-toxicity coefficient CTC, test result such as table 2, specifically
Calculation method is as follows:
A certain single dose is that standard agent (generally selects EC in mixture50Junior), it is calculated:
Toxicity index (TI)=standard agent EC50/ reagent agent EC50×100；
Theoretical toxicity index (TTI)=standard agent toxicity index × standard agent in mixing assembles percentage+
Reagent agent toxicity index × reagent agent percentage in mixing assembles；
Actual toxicity index (ATI)=standard single dose EC50Value/mixture EC50Value × 100；
Co-toxicity coefficient (CTC)=survey toxicity index/theoretical toxicity index × 100；
Co-toxicity coefficient classification: 120 mixture of CTC > have synergistic function, 80 mixture of CTC < have antagonism, 80
The mixture of≤CTC≤120 has summation action.
2 fluorine chlorine ether bacterium azoles of table compounds the indoor toxicity test to rice sheath blight disease with Ningnanmycin
As known from Table 2, fluorine chlorine ether bacterium azoles compounds between 50: 1~1: 50 with Ningnanmycin, has to rice sheath blight disease and increases
Effect effect, co-toxicity coefficient is 120 or more, when fluorine chlorine ether bacterium azoles compounds between 10: 1~1: 10 with Ningnanmycin, to water
The sheath and culm blight of rice has apparent synergistic effect, and the co-toxicity coefficient of the two compounding is 125 or more, when fluorine chlorine ether bacterium azoles and Ningnan are mould
It is the most obvious to rice sheath blight disease synergy when element compounding is than being 1: 1,1: 2,1: 3,1: 5,2: 3,5: 7,2: 1,3: 8, the two compounding
Co-toxicity coefficient 140 or more, when compounded with Ningnanmycin with fluorine chlorine ether bacterium azoles than being 2: 3, co-toxicity coefficient is up to
174.20, it is most significant to rice sheath blight disease synergy, and when fluorine chlorine ether bacterium azoles is compounded with Ningnanmycin than for 1: 60 and 60: 1, the two
Compounding is to rice sheath blight disease without synergistic effect, and co-toxicity coefficient is less than 120.
2, fluorine chlorine ether bacterium azoles is with Ningnanmycin combination preparation to the field control effectiveness test of rice sheath blight disease
Test process: the difference of each ingredient of this experimental evidence sets two medicaments dosage respectively, dosing be effectively at
The quality of point fluorine chlorine ether bacterium azoles and Ningnanmycin and.Comparison medicament is that 10% fluorine chlorine ether bacterium azole suspending agent and 21% Ningnan are mould respectively
Plain suspending agent and blank clean water experiment.
Test is administered 2 times altogether, is spaced 7d.Separately set the blank control not being administered.Rice varieties are rich late 347, test site
Changsha, Hunan Wangcheng area, plot area 30m2 are repeated 3 times, medical fluid dosage 450L/hm2.Investigation one before second of application
Secondary, 10d investigates an incidence after second of application, takes 5 points of samplings, and every investigation is connected 5 clumps, investigates 25 Cong Shui altogether
Rice, record total strain number, diseased plant number and disease index, calculates disease index and preventive effect.Severity Scaling takes 0,1,3,5,7,9 grade to be total to
6 ranks.
Disease index and control efficiency are calculated, and (DMRT method) for statistical analysis using SPSS16.0 version software:
Disease index=∑ (the disease number of sheets × typical value at different levels at different levels)/investigation total number of sheets × superlative degree typical value × 100%
2 fluorine chlorine ether bacterium azoles of table is with Ningnanmycin combination preparation to the field control effectiveness test of rice sheath blight disease
As can be seen from Table 2, rice sheath blight disease, control efficiency can be effectively prevented after fluorine chlorine ether bacterium azoles is compounded with Ningnanmycin
It is superior to single dose preventive effect, and the lasting period is long, had no adverse effects in test scope of medication to Target crops.
