Description
Technical field
The invention belongs to technical field of pesticide, are related to a kind of bactericidal composition of fluorine-containing indenes azoles bacterium amine.
Background technique
Fluorine indenes azoles bacterium amine chemical name：3- difluoromethyl-N- (the fluoro- 2,3- dihydro -1,1,3- trimethyl -1H- indenes -4- of 7-
Base) -1- methyl-1 H- pyrazole-4-carboxamide, belong to wide spectrum SDHI class fungicide, fungicidal spectrum covers all thifluzamides and Lu Na
Gloomy fungicidal spectrum, in addition to Rhizoctonia solani special efficacy, all to anthrax, rust, early blight, powdery mildew, leaf mold, false smut preventive effect
Very well.It will be high than Lu Nasen, green prince wife's activity especially in terms of powdery mildew.Structural formula is as follows：
Kasugarnycin (Kasugamycin) is aminoglycoside antibiotics, is produced by springtime streptomycete and streptomyces microaureus
It is raw, since it is with significant anti-fungal activity of plant pathogenic, therefore successfully just agriculturally it is being widely used from formulating.To on rice
Rice blast have excellent preventive effect and therapeutic effect.Prevent and treat watermelon bacterial angular leaf spot, peach gummosis, shot hole, shothole disease etc.
Disease has special efficacy.
Ningnanmycin (ningnanmycin) is the tunning by being isolated fungi in Ningnan County, Sichuan Province soil,
It is a kind of Cystosine nucleocide type antibiotics.The antibiotic is a kind of low toxicity, low-residual, nothing " three cause " and accumulation problems, no
The novel pesticide of environment is polluted, obvious to bacterial blight of rice relative control effect, in addition it is to powdery mildews such as wheat, vegetables, flowers
Diseases prevention, effect of increasing production are all very significant, to small round sclerotial disease of rice, Olive peacock's eye disease, shot hole and tobacco mosaic disease preventive effect
Also very well, while in tobacco mosaic virus disease, tomato virus disease, pepper virus disease, rice seedling blight, root rot, rice
Stripe virus disease, alternaria leaf spot of apple achieve registration in powdery mildew of cucumber, furthermore in prevention and treatment sclerotinia sclerotiorum, lichee frost
Phytophthora root rot has also been widely applied in the multiple diseases such as other crop virosis, stem rot, blight dis-ease, powdery mildew.
Shenqinmycin is a kind of antibiotic secreted by Pseudomonas fluorescens through biological culture, while there is wide spectrum to inhibit to plant
Object pathogen and the dual function for promoting Effects on Plant Growth, the biological bactericide have the characteristics that wide spectrum, efficient, can effectively prevent
Wilt disease, blight dis-ease, epidemic disease, banded sclerotial blight, false smut, rice blast, the downy mildew, item rust harnessed the river on the crops such as rice, wheat, vegetables
Disease, sclerotiniose, head blight, anthracnose, gray mold, scab, leaf spot, bacterial wilt, canker, ginger plague and soil-borne disease soil
Processing.
Since various regions pesticide abuse causes resistance increasing, the lasting raising of the dosage of pesticide.However larger dose
Pesticide abuse causes to make havoc of environment, does not also play due effect well.Pass through our a large amount of field medicines
Effect test discovery, the mixed generation that can be very good delaying drug resistance of pesticide improve drug effect, to reduce the usage amount of pesticide.
Summary of the invention
The object of the present invention is to provide a kind of safety and environmental protections, improve drug effect, the sterilization for extending the lasting period, reducing labour cost
Composition.
Above-mentioned bactericidal composition, active components A be fluorine indenes azoles bacterium amine, active constituent B be selected from kasugarnycin, Ningnanmycin,
One of shenqinmycin is several, and the weight ratio of active components A and active constituent B are 1：30~30：1, active components A with
The preferred weight ratio of active constituent B is 1：20~20：1, the more preferable weight ratio of active components A and active constituent B are 1：10~
10：1.
Using bactericidal composition of the present invention, it is equipped with auxiliary agent known to those skilled in the art, in the art
Dosage form according to the present invention is made in method well known to technical staff：Suspending agent, microcapsule suspending agent, suspension seed-coating agent, wettable
Pulvis, water dispersible granules, dispersible oil-suspending agent.
Above-mentioned bactericidal composition has the characteristics that：1. fluorine indenes azoles bacterium amine belongs to novel environment friendly fungicide, bactericidal effect is strong,
Two kinds of ingredient compoundings, have good synergistic effect；2. delaying the generation of effective component resistance, the labour cost of peasant is reduced；
3. two kinds of ingredients are without apparent cross resistance, environmentally safe.
Specific embodiment
In the present invention, to verify the synergistic effect after active components A is compounded with active constituent B, using indoor biological activity
With two methods of field control effectiveness test, the two kinds of test methods used are described individually below.Wherein, active constituent
A is fluorine indenes azoles bacterium amine, and active constituent B is kasugarnycin, Ningnanmycin, shenqinmycin.

Rice rice blast pathogen.Reference《Farm-chemical indoor determination test rule fungicide》It carries out, calculates each medicament to pathogen
EC50, compare the virulence and bacteriostasis of different agents.
The co-toxicity of mixture preparation is indicated using the co-toxicity coefficient method of Sun Yunpei：
Mixture preparation survey toxicity index
The mixture preparation theoretical toxicity index TTI=∑ (pharmaceutically active ingredient of the toxicity index ATI of certain medicine × in mixture
Percentage).
The co-toxicity coefficient of mixture preparation
Co-toxicity coefficient CTC is synergistic effect when being greater than 120, is antagonism when less than 80, is when between 80~120
Addition.
1 fluorine indenes azoles bacterium amine of table is with kasugarnycin different ratio to the measurement result of rice Pyricularia grisea co-toxicity coefficient
As can be seen from Table 1, when fluorine indenes azoles bacterium amine and kasugarnycin compound in varing proportions, the total poison system of compound preparation
Number (CTC) is all larger than 120, there is the synergistic effect of different proportion to the prevention and treatment of rice blast.
Test two：The indoor biometrics experiment that fluorine indenes azoles bacterium amine is compounded with Ningnanmycin, subjects are powdery mildew of cucumber disease
Bacterium.Reference《Farm-chemical indoor determination test rule fungicide》It carries out, calculates each medicament to the EC of pathogen50, than less
With the virulence and bacteriostasis of medicament.
2 fluorine indenes azoles bacterium amine of table is with Ningnanmycin different ratio to the measurement result of cucumber powdery mildew bacteria co-toxicity coefficient
As can be seen from Table 2, when fluorine indenes azoles bacterium amine and Ningnanmycin compound in varing proportions, the total poison system of compound preparation
Number (CTC) is all larger than 120, there is the synergistic effect of different proportion to the prevention and treatment of powdery mildew of cucumber.
Test three：The indoor biometrics experiment that fluorine indenes azoles bacterium amine is compounded with shenqinmycin, subjects are rice sheath blight disease disease
Bacterium, reference《Farm-chemical indoor determination test rule fungicide》It carries out, calculates each medicament to the EC of pathogen50, than less
With the virulence and bacteriostasis of medicament.
3 fluorine indenes azoles bacterium amine of table is with shenqinmycin different ratio to the measurement result of rice sheath blight disease germ co-toxicity coefficient
As can be seen from Table 3, when fluorine indenes azoles bacterium amine and shenqinmycin compound in varing proportions, the total poison system of compound preparation
Number (CTC) is all larger than 120, there is the synergistic effect of different proportion to the prevention and treatment of rice sheath blight disease.
It can be seen that after two kinds of active components compounding by the above raw test, drug effect increases, the two compounding
There is good synergistic effect afterwards.
