Abstract
The invention discloses a bactericidal composite containing mandipropamid and cymoxanil, a preparation method and application thereof, which is the mixture of compound (A) mandipropamid and compound (B) cymoxanil, and is characterized in that the weight ratio of active ingredients mandipropamid to cymoxanil is 1-50:1-50. The content of active ingredients in the composite is 1-90%. The mixture can be processed into suspending agent, wettable powder and water dispersible granules. The bactericidal composite containing the mandipropamid and cymoxanil has high fungicidal efficiency, and can effectively prevent and treat plant diseases on multiple crops such as potato, tomato, cucumber, grape and the like.The control effect of the insecticidal composition is obviously superior to that of the single compound (A) or compound (B), and the application dosage of various bioactive substances can be reduced.
Description
Technical field
The present invention relates to a kind of bactericidal composition, relate to a kind of Synergistic bactericidal composition that contains mandipropamid amine and white urea cyanogen and uses thereof specifically with synergism performance.
Background technology
The chemical name of compound (A) mandipropamid amine be 2-(4-chloro-phenyl)-N-[2-(3-methoxyl group-4-(2-third alkynyloxy group)-phenyl-ethyl group]-2-(2-third alkynyloxy group)-acetamide.
Its structural formula is:
Mandipropamid amine, English common name mandipropamid, trade name is auspicious all.Being the new type bactericide by Syngenta Co.,Ltd's exploitation, also is first commercial mandelic acid amides compound.Mandipropamid amine all has active preferably to Oomycete pathomycetes such as Peronospora and Phytophthoras, especially potato late blight, tomato late blight, cucumber downy mildew and downy mildew of garpe etc. are had special efficacy.Just reaching earlier the mandipropamid amine that obtains to register in China is 25% suspending agent, and registration crop and disease are watermelon eqpidemic disease, capsicum epidemic disease, potato late blight and peronophythora litchi.
The mechanism of action of mandipropamid amine and iprovalicarb, benzene metsulfovax and dimethomorph is similar, by disturbing phosphatide and the biosynthesis of cell wall sediments of pathomycete, reaches the sprouting and the mycelial growth that suppress spore.
The chemical name of the white urea cyanogen of compound (B) is 2-cyano group-N-[(ethylamino-) carbonyl]-2-(methoxyl group imido grpup) acetamide.
Structural formula is:
Frost urea cyanogen is the bactericide with local systemic action by E.I.Du Pont Company's exploitation.Can effectively prevent and treat the disease of Peronosporaceae vaccine genus, Plasmopara and Peronospora.Extensive use and the downy mildew and the late blight of preventing and treating on potato, tomato, grape, cucumber, the Chinese cabbage etc. crops.The preparation of registration has 80% white urea cyanogen WP and 72 MnZns frost urea WP at present.
The common feature of mandipropamid amine and white urea cyanogen is the disease that can prevent and treat Phytophthora and Peronospora.All can prevent and treat eqpidemic disease and downy mildew on the crops such as potato, tomato, cucumber, grape.
Mandipropamid amine and white urea cyanogen are mixed with suitable ratio, not only can improve drug effect, reduce dosage, save Financial cost, reduce medicament residual in environment.Simultaneously can also delay the drug-fast generation of crop pest, prolong the service life of medicament.Also do not find at present the report of using with of pyrrole aphid ketone and Nitenpyram.
Summary of the invention
The bactericidal composition that the purpose of this invention is to provide mandipropamid amine and white urea cyanogen, after the two mixes according to suitable ratio, by modern pesticidal preparations process technology, be processed into conventional pesticide formulations such as suspending agent, wetting powder, water dispersible granule, be used to prevent and treat eqpidemic disease and downy mildew on the crops such as potato, tomato, cucumber, grape.
Bactericidal composition provided by the invention is characterized in that comprising compound (A) mandipropamid amine and the white urea cyanogen of compound (B).Weight ratio between compound in microbicide compositions of the present invention (A) and the compound (B) generally is:
(A) mandipropamid amine is 1-50: 1-50 with (B) white urea cyanogen.
Bactericidal composition provided by the present invention can effectively be prevented and treated the disease on the various crop such as potato, tomato, cucumber, grape.Preventive effect is significantly higher than the preventive effect of compound alone (A) or compound (B), and can reduce the application dosage of each bioactivator.
The present invention is used to prevent and treat the disease on the various crop such as potato, tomato, cucumber, grape.Do spraying at the disease initial stage of origination and handle, the method for processing can be by adding good composition or before use that the different activities component is mixed and handled.
Adoptable surfactant has anion surfactant and non-ionic surface active agent.It comprises alkylsurfuric acid salt, alkyl sulfonic acid alkali metal salt and amido, dialkyl group succinate sodium sulfonate salt, alkylphenol polyoxyethylene formaldehyde condensation products sulfonate, sodium sulfate of polyethenoxy ether of fatty alcohol alkyl polyoxyethylene ether sulfate, alkylnaphthalene sulfonate, fatty acid or fatty acid ester sulphate, alkylphenol polyoxyethylene and fatty alcohol-polyoxyethylene ether etc.That can give an example has farming newborn 2000 series, lignosulfonates, NNO, a dispersing agent MF etc.
Suspending agent is that the mixture of each active component, emulsifier, wetting agent, dispersant etc. are pulverized by wet grinding together, make it evenly to disperse and suspend, can suitably add simultaneously suitable auxiliary agent such as thickener, antifreezing agent, stabilizing agent, bleeding agent as required, active principle content is 1-80% (weight).
Wetting powder is with the mixture of active component, inert carrier and filler and one or more wetting agents, dispersant, bleeding agent, obtains wetting powder by ultramicro grinding, and active principle content is 1-90% (weight) in the wetting powder.
Water dispersible granule is with the mixture of active component, inert carrier and filler and one or more wetting agents, dispersant, bleeding agent, after ultramicro grinding, carries out granulation by fluid bed or fashion of extrusion after adding a certain amount of binding agent.
Bactericidal composition provided by the invention has following beneficial effect: the germicidal efficiency height, can effectively prevent and treat the disease on the various crop such as potato, tomato, cucumber, grape.Preventive effect is significantly higher than the preventive effect of compound alone (A) or compound alone (B), and has significantly reduced the application dosage of every kind of active substance.The present invention not only has ecological significance, also has important environment protection significance simultaneously.
