Description
Technical field
The invention belongs to disinfectant use in agriculture field, be specifically related to a kind of benzothiostrobin and the Bactericidal composite of fluorine ether bacterium acid amides
Thing.
Background technology
Benzothiostrobin (English common name: benzothiostrobin), for methoxy acrylic bactericide, mitochondria
Respiratory chain cytochrome b c1 complex inhibitor, has a good security to beneficial organism and crop, low toxicity and to environment friend
Good.Can be widely used for preventing and treating sclerotinia rot of colza, rice green smut, corn southern leaf blight, oranges and tangerines ground maize ear rot and vegetables and melon and fruit class is white
The various crop fungal diseases such as powder disease, downy mildew, gray mold, brown spot, scab.But it is used alone solvent for a long time and makes disease
Develop immunity to drugs.Compounding between the active ingredient of the different mechanisms of action is the common practices delaying disease to develop immunity to drugs, according to
Actual production, compounding effective formula, preventive effect can be significantly improved, be substantially reduced the consumption of agricultural chemicals, expand fungicidal spectrum, improve
Sterilization, alleviates the pollution to environment, reduces agricultural cost.
Fluorine ether bacterium acid amides (English name: Fluoride ether bacteria amide), is a kind of novel fluorine benzoyl
Amine bactericide, its mechanism of action is the respiratory chain acting on fungal mitochondria, the activity of suppression succinate dehydrogenase, thus hinders
Disconnected electron transmission, suppresses fungus spore germination, and germ tube extends, and mycelial growth and spore mother cell's formation etc., for rape sclerotium
The multiple fungoids such as disease, rice green smut, banded sclerotial blight, downy mildew of garpe, Phytophthora capsici, the late blight of potato, cotton seedling blight
Disease all has higher preventive effect.Patent No. CN102302012A discloses and benzothiostrobin and nitrile bacterium azoles carries out compounding acquirement significantly
Synergistic function, 201410123281.X discloses and benzothiostrobin and epoxiconazole carries out compounding acquirement notable Synergistic work
With, and the report carrying out compounding about epoxiconazole and other bactericide is the most.But do not find benzothiostrobin and fluorine ether bacterium
Acid amides carries out correlative study or the report compounded.
Summary of the invention

The described bactericidal composition containing benzothiostrobin and fluorine ether bacterium acid amides is in the preventing and treating multiple fungal disease of crops
Application.
The described bactericidal composition containing benzothiostrobin and fluorine ether bacterium acid amides is in preventing and treating sclerotinia rot of colza, rice green smut
Application.
Wadley method is used to carry out benzothiostrobin and the design of fluorine ether bacterium acid amides proportioning screening test and result treatment, first
Measure benzothiostrobin and the EC of fluorine ether bacterium acid amides50, according to its EC50The portfolio ratio of two medicaments is set by Wadley method, and according to
Wadley synergy index SR value, determines the two suitable proportionings of component, is then verified by the abundant method of Sun Yun.
Test objective thing is sclerotinia rot of colza sclerotinite, and test uses colony diameter method.Benzene thiophene is prepared according to experimental design
Bacterium ester, fluorine ether bacterium acid amides pastille flat board, every ware 20ml, arrange and compare (CK) without medicine flat board, often process 3 times and repeat.In preculture
The colony edge mycelia block taking 5mm diameter moves on on different culture media flat board respectively, cultivates 5d, measures colony diameter for 28 DEG C
(mm), and by following equation growth inhibition ratio is calculated:
Mycelial growth inhibition rate is converted into suppression probit value (Y), and drug concentration is converted into log concentration (X), by concentration
Logarithm be abscissa, probit value be that ordinate makees toxicity regression straight line, try to achieve benzothiostrobin and fluorine ether bacterium acid amides single dose and mixed
The agent virulence regression equation to sclerotinite, and calculate EC50、EC90Value and correlation coefficient r value.
Evaluate the interaction of mixture according to Wadley method, computing formula is as follows:
EC50 (theoretical values)=(a+b)/(a/EC50a+b/EC50b), SR=EC50 (theoretical values)/EC50 (actual values)。
Wherein a, b are each component content ratio in mixture, analyze the effect of mixture with SR value.SR≤0.5, then two kinds of medicines
Agent mixture has antagonism；SR=0.5～1.5, then two kinds of medicament mixtures have addition；SR >=1.5, then two kinds of medicament mixtures
There is synergistic effect.
Table 1 benzothiostrobin and fluorine ether bacterium acid amides single dose and mixture thereof are to sclerotinite toxicity test result
As it can be seen from table 1 benzothiostrobin and benzothiostrobin and fluorine ether bacterium acid amides have well preventing and treating to sclerotinia rot of colza
Effect, in benzothiostrobin: when fluorine ether bacterium acid amides weight ratio is 15:1～1:15, SR is both greater than 1.5, has synergistic effect, especially
Being benzothiostrobin: when fluorine ether bacterium acid amides weight ratio is 5:1, SR is up to 2.21, synergistic effect is notable, actually used in can improve
Preventive effect, reduces dosage, reduces and uses agriculture originally.
The present invention has higher prevention effect to crop fungal disease, there is notable synergistic effect between two components；Can
Reduce dosage, effectively reduce ecological disruption and environmental pollution, and crop yield and quality can be improved；2-cyano-3-amino-3-phenylancryic acetate in the present invention
The toxicity such as low is all belonged to fluorine ether bacterium acid amides, and to people and animals, beneficial organism, Environmental security；Germ can be delayed single medicament
The resistance to the action of a drug.
