Description
Technical field
What a kind of Bactericidal active ingredient composition of the present invention related to is a kind of new Fungicidal active compound composition, comprises a kind of known oxime ether derivatives and copper calcium sulfate, and said composition is highly suitable for control phytopathogenic fungi and bacterium.
Background technology
In horticultural crop and dry-land crop production, crop can run into multiple fungi or infecting of bacterium and various disease, also normal because of in soil multiple cause a disease or saprophytic fungi (as mould in corruption, epidemic disease is mould, Rhizoctonia solani Kuhn, sickle-like bacteria, botrytis cinerea etc.) and bacterium (soft-rot fungi etc.) infect harm, cause rotten kind, rotten, extremely seedling.
Oxime bacterium ester (Trifloxystrobin) Chinese name cry again oxime grass ester or trifluoro quick, its chemical name is (2Z)-2-methoxyimino-2-[2-[[1-[3-(trifluoromethyl) phenyl] ethyleneimino] oxygen methyl] phenyl] methyl acetate, and its structural formula is:
Oxime bacterium ester is the fungicides that the class successfully developed as bactericide lead compound from natural products Strobilurins is new.It is a kind of respiratory chain inhibitor; cell adenosine triphosphatase ATP is stoped to synthesize by the electron transmission pinned between cytochrome b and 1; thus suppress its mitochondrial respiratory and play bacteriostasis; it is the bactericide with chemical kinetics characteristic; can, by plant wax coat strong adsorption, show to provide excellent prolection to plant.There is efficient, wide spectrum, protection, treat, root out, permeate, the characteristic such as systemic activity, fast distribution; it has interior absorption upwards to Crop soon, in addition; therefore resistance of rainwater washing against performance is good, the lasting period is long, is therefore considered to second generation methoxy acrylic bactericide.To Isosorbide-5-Nitrae-demethylation enzyme inhibitor, benzamides, the bacterial strain that dicarboxyl amine and benzimidazole produce resistance is effective, with current existing bactericide without cross resistance.
Oxime bacterium ester (Trifloxystrobin) all has good activity to nearly all Mycophytes (Ascomycetes, Basidiomycetes, Oomycete and Fungi Imperfecti) disease such as powdery mildew, rust, Ying's rot, net blotch, downy mildew, rice blast etc.Except having special efficacy to powdery mildew, leaf spot, there is good activity to rust, downy mildew, damping off, apple apple scab.Oxime bacterium ester is mainly used in cauline leaf process, and prolection is excellent, and has certain therapeutic activity, and activity is not affected by environment, and application optimal period is spore germination and their early stage stage, but all has activity each period to scab.The activity of this compound is good, but sometimes unsatisfactory when low rate of application.
Copper calcium sulfate is a kind of known compound crop to protective effect, is the bactericide of wide spectrum, has good preventive effect to all fungoid and bacterial disease.The copper ion of its uniqueness and calcium ion macromolecular complex thing, guarantee that copper ion slowly, lastingly discharges.Copper, calcium ion have micro-fertilizer effect, can increase plant chlorophyll, strengthen photosynthesis, improve premunition, have certain production-increasing function, but do not have systemic action.The activity of this compound is good, but sometimes unsatisfactory when low rate of application.
Because the present environmental requirement to bactericide and economic requirement continue to improve, such as to the requirement of activity profile, toxicity, selectivity, rate of application, residue composition and favourable preparation feasibility, in addition owing to may have problems in such as drug resistance, therefore, exploitation is better than the new bactericide of existing fungicide is in some aspects lasting task.
The invention provides active compound combinations, it at least achieves the above object in some aspects.

biological test example
When the effect of active compound combinations exceedes the summation of the effect when each reactive compound is used separately, there is synergistic function.The predictive role of the particular combination of two kinds of reactive compounds can use so-called " Colby formula " (see S.R. Colby, " Calculating Synergistic and Antagonistic Responses of Herbicide Combinations ", Weeds 1967,15,20-22) calculate as follows: if
X is the activity when using the reactive compound A that consumption is mppm for mg/ha or concentration;
Y is the activity when using the reactive compound B that consumption is nppm for ng/ha or concentration, is expressed as the percentage accounting for untreated control;
E is when using consumption for activity during m and n g/ha or the concentration reactive compound A and B that is m and n ppm,
So
If the activity of actual observation (O) is greater than expection active (E), so said composition super add and, namely there is synergistic effect.
Following biological test example is in order to illustrate the present invention.But the present invention is not limited to these embodiments.
The mould test of epidemic disease (tomato)/protectiveness
Solvent: the acetone of 24.5 weight portions
The dimethylacetylamide of 24.5 weight portions
Emulsifier: 1 weight portion alkylaryl polyglycol ether
For preparing suitable active agent preparations, the solvent of the reactive compound of 1 weight portion or active compound combinations and above-mentioned amount and emulsifier are mixed, and the concentration needed for this dope of dilute with water, or the preparation of commercially available reactive compound or the preparation of active compound combinations and water are diluted with water to required concentration.
For test prolection, spray rice shoot with active agent preparations with affiliated rate of application.After spraying layer exsiccation, inoculate this plant with the aqueous phase spore suspension of phytophthora infestans (Phytophthora infestans).Then plant is placed on about 20
oc, relative air humidity are in the culturing room of 100%.
Inoculate latter 3 days to measure.Now, 0% refers to the drug effect equaling control group, and 100% refers to and do not observe infection.
The mould test of epidemic disease (tomato)/protectiveness
The activity that upper table clearly shows active compound combinations of the present invention is greater than the activity calculated, and namely oxime bacterium ester and copper calcium sulfate exist synergistic effect in the scope of 1:1 to 1:100.
