Description

The bactericidal composition of Enestroburin and thiocarbamate
Technical field
The invention belongs to the disinfectant use in agriculture field.
Background technology
Enestroburin is the outstanding bactericide of plurality of plant diseases such as control cereal, paddy rice, fruit, vegetables and economic crops, its fungicidal spectrum wide, active high, have prevention and therapeutic action and good compatibility arranged, to good control efficiency being arranged by mastigomycetes, the plurality of plant diseases that causes in conjunction with bacterium, sac fungi, basidiomycetes and imperfect fungus with environmental organism.This compound is formulated, is disclosed first in CN1191670A by Chinese Shenyang Chemical Engineering Inst.Enestroburin belongs to the new type bactericide of methoxy acrylic, and this series bactericidal agent activity is high, consumption is few, has treatment and protective effect, is widely used in preventing and treating corps diseases.But because the action site of this series bactericidal agent is very single, germ can produce adaptive variation to medicament, the preventive effect of medicament is reduced even invalid, develops immunity to drugs.The resistance of Enestroburin is found as yet in the field at present, but is had the relevant report that produces resistance in Europe with veriety.
Summary of the invention
For fear of the resistance of using the agent of Enestroburin list to bring take place, degradation problem under the drug effect, the invention discloses a kind of bactericidal composition, preparation of compositions and application that contains Enestroburin and thiocarbamate.
Enestroburin chemical name: 3-methoxyl group-2-[2-((((1-methyl-3-(4-chlorphenyl)-2-acrylic fork) amino) oxygen)-methyl) phenyl] methyl acrylate, structural formula is as follows:
Chinese common name: Enestroburin molecular formula: C 22H 22CINO 4Molecular weight: 399.87
Carbamates bactericidal agent of the present invention mainly is selected from:
Mancozeb chemical name: the polycomponent coordination compound of ethylene bisdithiocarbamic manganese and zinc salt;
Maneb chemical name: ethylene bisdithiocarbamic manganese;
Zineb chemical name: ethylene two (zinc dithiocarbamate);
Propineb chemical name: acrylic bisdithiocarbamic zinc;
Ambam chemical name: acrylic bisdithiocarbamic ammonium;
In generation,, gloomy salt chemical name claimed: two (zinc dithiocarbamate) metal complexes of ethylene;
Tmtd chemical name: tetramethyl thiuram disulfide;
Diram chemical name: N, N dimethyl dithiocarbamic acid ammonium or
Ziram chemical name: two (dimethyl dithiocarbamic acid) zinc.
Bactericidal composition disclosed by the invention, wherein containing Enestroburin and any one Carbamates bactericidal agent is active component.Also can contain two or more Carbamates bactericidal agent in this bactericidal composition, can realize purpose of the present invention equally.
Have now found that the use that is mixed of Enestroburin and sulfo-amino hydrochlorate has obvious synergistic effect, the control efficiency of corps diseases is significantly increased, and can enlarge fungicidal spectrum, delay the drug-fast generation of pathogen.Enestroburin possesses different structure types and different mechanism of action with sulfo-amino Barbiturates medicament, and the two is composite can to delay to a certain extent that the pathogen pesticide resistance produces and development, can reduce use cost simultaneously.
In the bactericidal composition that the present invention proposes, Enestroburin and thiocarbamate are 1: 100 to 100: 1 based on the ratio of weight and number of active component; Suitable ratio is 1: 20 to 20: 1.
Active component is 0.5% to 95% of a gross weight in the composition of the present invention.The amount of application of compound also depended on the ratio of a kind of compound and another kind of compound and the degree of synergistic effect when the amount that contains active component in the present composition depended on independent the use.
