Abstract
The invention provides to a bactericidal composition containing mandipropamid and mancozeb and a preparation method and application. The composition is the mixture of the compound (A) mandipropamid and the compound (B) mancozeb. The composition is characterized in that the weight ratio of the active ingredient mandipropamid to the active ingredient mancozeb in the composition is 1-50:1-50; the content of the active ingredients in the composition is 1-90%; and the composition can be processed into suspending agents, wettable powder and water-dispersible granules. The bactericidal composition has high bactericidal efficiency and can effectively control the diseases on various crops such as potatoes, tomatoes, cucumbers, grapes, etc. The control effect of the composition is obviously better than that of the single compound (A) or compound (B), thus substantially reducing the application dosage of various active substances.
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 mancozeb 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.
Compound (B) mancozeb is the complex compound of zinc and maneb.Rohm ﹠amp was arranged in 1961; Hass Company promotes, and has obtained patent BP996264; USP2504404.
Mancozeb is that the bactericidal mechanism of dithiocarbamates is many-sided; but it is mainly the oxidation that suppresses pyruvic acid in the thalline; with the sulfydryl combination in the dithio-octanoic acid dehydrase that participates in the pyruvate oxidation process; in generation,, gloomy compounds was converted into different sulphur hydrocyanic ester earlier; again with sulfydryl combine thereafter; main is different sulphur cyanogen methyl esters and curing ethylene diamine thioformyl; the most important toxic reaction of these products also is the SH base on the aleuroplast (mainly being enzyme); the SH that reacts on the most tangible the fastest coacetylase molecule combines based on metallic bond in the complex compound, thereby reaches the purpose of sterilization.
Mancozeb is a kind of broad spectrum protection bactericide.Vaccine to Phycomycetes belongs to, the Cercospora of Fungi Imperfecti, and the various crop disease that Ascochyta etc. cause all has good control efficiency.
The single agent of the formulation of the mancozeb that existing market is commonly used is a mancozeb wettable powder, and the formulation that is mixed mainly is the mix preparation of mancozeb and white urea cyanogen.
The common feature of mandipropamid amine and mancozeb is eqpidemic disease and the downy mildew that can prevent and treat on the crops such as potato, tomato, cucumber, grape.
Mandipropamid amine and mancozeb 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.
Summary of the invention
The bactericidal composition that the purpose of this invention is to provide mandipropamid amine and mancozeb, 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 granules, 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 compound (B) mancozeb.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) mancozeb.
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 granules 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.
