Abstract

A kind of purposes of composition pesticide containing 2-cyano-3-amino-3-phenylancryic acetate and kind bacterium azoles in bakanae disease of rice is prevented and treated.The invention discloses a kind of composition pesticide new application for preventing and treating bakanae disease of rice.It contains 1 60 parts by weight 2-cyano-3-amino-3-phenylancryic acetates and 1 40 parts by weight kind bacterium azoles.The composition pesticide of the present invention has significant synergies on fusarium moniliforme mycelial growth is suppressed, and the field control to bakanae disease of rice also has good effect, can substantially reduce pesticide dosage, reduce cost, reduces environmental pollution and residues of pesticides.The present invention can effectively administer the resistance to the action of a drug of the fusarium moniliforme to main flow medicament carbendazim and Prochloraz, reduce resistance risk of the 2-cyano-3-amino-3-phenylancryic acetate in agricultural production, increase its effective service life, and it simultaneous can control the rice shoot sprout term disease as caused by soil passes sickle-like bacteria and rhizoctonia, for the resistance management of China's bakanae disease of rice, increase society, economy, ecological benefits will have application value.

Description

A kind of composition pesticide containing 2-cyano-3-amino-3-phenylancryic acetate and kind bacterium azoles is in preventing and treating bakanae disease of rice In purposes
Technical field
The invention belongs to technical field of pesticide, and in particular to a kind of use of composition pesticide in bakanae disease of rice is prevented and treated On the way, a kind of purposes of disinfectant use in agriculture in bakanae disease of rice is prevented and treated is further related to.
Background technology
2-cyano-3-amino-3-phenylancryic acetate (tested number：JS399-19, English name：Phenamacril), chemical name：2- cyano group -3- amino - 3- ethyl phenylacrylates, molecular formula：C12H12N2O2, chemical structural formula is as follows：
2-cyano-3-amino-3-phenylancryic acetate is the new selection of cyanoacrylate researched and developed by Jiangsu base, National Research and Development Center for Pesticides Property bactericide, have to the mycelial growth of pathogenic Fusarium graminearum, Asia sickle-like bacteria and Fusarium oxysporum etc. strong special The property changed inhibitory action.The new type bactericide has obtained Chinese invention patent at present, and completed in 2005 agricultural chemicals registration temporarily and Obtain formal registration within 2011.Since 2-cyano-3-amino-3-phenylancryic acetate enters market, played in the prevention and control of wheat scab and bakanae disease of rice Important function.Especially in fusarium graminearum and fusarium moniliforme conventional sterilants carbendazim etc. is being developed immunity to drugs Area, turn into effective surrogate-data technique, still, desk research shows, sickle-like bacteria is in the continuous single selection pressure of 2-cyano-3-amino-3-phenylancryic acetate Easily develop immunity to drugs, higher resistance risk be present.Therefore, it is anti-in order to delay or overcome pathogen to be produced to 2-cyano-3-amino-3-phenylancryic acetate It is Critical policies that the bactericide wheel of the property of medicine and expansion diseases prevention spectrum, 2-cyano-3-amino-3-phenylancryic acetate and other modes of action, which is used or is used in mixed way,.
Kind bacterium azoles (code name：KNF-317, English name：Ipconazole), chemical name：2- ((4- chlorobenzyls) methyl -5- (1- isopropyls) -1- (1H-1,2,4- triazole -1- methyl) cyclopentanol, molecular formula：C18H24ClN3O, chemical structural formula are as follows：
Kind bacterium azoles are a kind of triazole type ergosterol biosynthesis inhibitors, have interior suction, protection and therapeutic activity, can have Effect ground prevents and treats a variety of sac fungus, basidiomycetes and disease caused by Fungi Imperfecti, is conducted by seed treatment from root to cauline leaf, to red mould Disease, leaf spot, droop have good preventive effect.
Bakanae disease of rice is a kind of Common Species fax fungal disease, can be occurred in each paddy fields in the world, mainly by Infected seed is propagated, and the incidence of disease is high, Rice Production is threatened it is very big, typically can the underproduction 10~20%, be up to when serious 50% with On.In recent years, especially Jiangsu Province the incidence of disease in ascendant trend year by year, occurrence degree also be in exacerbation trend, and grave illness field is sent out Sick rate is up to 35%, and spraying preventing and treating is mainly soaked seed or carried out using carbendazim, Prochloraz etc. in production.However, carbendazim is because anti- Several near failures of preventing and treating of the sex chromosome mosaicism to bakanae disease.Prochloraz is used as paddy rice seed soaking agent and prevents and treats bakanae disease also more than 20 years.Research Show, bakanae disease of rice is higher to Prochloraz resistance risk, and some areas have produced moderate resistance and high antibacterial strain, are soaked using Prochloraz Kind prevention and control bakanae disease is present compared with high drug-resistance risk.
Therefore, the present inventor is on the basis for summarizing prior art, by the 2-cyano-3-amino-3-phenylancryic acetate with the different mechanisms of action and Kind bacterium azoles are combined prevention and control bakanae disease of rice, and by lot of experiments and analysis, the microbicide compositions are carried out in seedling stage Seed treatment has preferable synergistic function to bakanae disease of rice.
The content of the invention
Goal of the invention：There is synergy it is an object of the invention to provide one kind and expand antimicrobial spectrum effect composition pesticide anti- The purposes harnessed the river in the Bakanae disease of rice.It is a further object of the present invention to provide a kind of agricultural bactericidal agent formulation in preventing and treating bakanae disease of rice In purposes.
Technical scheme：In order to solve the above technical problems, the present invention provides a kind of agricultural chemicals containing 2-cyano-3-amino-3-phenylancryic acetate and kind bacterium azoles Purposes of the composition in preventing and treating bakanae disease of rice.In described composition pesticide, the weight ratio of 2-cyano-3-amino-3-phenylancryic acetate and kind bacterium azoles is 1 : 60~40: 1.

Experimental example：Toxicity determines
Virulence and interaction coefficient of synergism of the composition of indoor measurement 2-cyano-3-amino-3-phenylancryic acetate and kind bacterium azoles different proportion to target.Its Method is dissolved into 1000 μ g/mL mother liquors using 2-cyano-3-amino-3-phenylancryic acetate and kind bacterium azoles active compound with methanol, and 4 DEG C save backup.By 2-cyano-3-amino-3-phenylancryic acetate Be configured to 1: 40,1: 20,1: 10,1: 5,1: 1,5: 1,10: 1,20: 1,40: 1 mixtures respectively by effective content with kind bacterium azoles is Row test solution, culture matrix (PDA) is then mixed into, determines the inhibitory activity to fusarium moniliforme mycelial growth, calculate EC50Value and Coefficient of synergism.
Mycelial growth average inhibition=[(control colony diameter average-processing colony diameter average)/(control bacterium colony is straight Footpath average-inoculation bacteria cake diameter)] × 100%.Using DPS data handling systems, regression equation and EC are calculated50Value.Press Wadley methods, calculate coefficient of synergism (SR).
The synergy type of pharmacy mix is evaluated according to coefficient of synergism (SR), i.e. SR ＜ 0.5 are antagonism, 0.5≤ SR≤1.5 are summation action, and SR ＞ 1.5 are synergistic effect.SR=EC50(Eth)/EC50(Eob), EC50(Eth)=(a+b)/ [(a/EC50A)+(b/EC50B)].Wherein, A, B are respectively bactericide single dose, and a, b are ratio of the corresponding single dose in mixture, EC50 (Eth) it is mixture EC50Theoretical value, EC50(Eob) it is mixture EC50Measured value.
It is can be seen that according to the result of table 1 when the proportioning of 2-cyano-3-amino-3-phenylancryic acetate and kind bacterium azoles is 1~60: 40~1, rice disliked The EC of seedling diseases bacterium50For 0.0377~0.2443 μ g/ml, coefficient of synergism is 1.66~2.10, has reached the effect of synergy.
