Abstract
The invention discloses a kind of bactericidal composition preventing and treating wheat powdery mildew, effective ingredient is prothioconazoles and bupirimate, and the mass fraction of prothioconazoles and bupirimate is than for 30:1～1:30.There are obvious potentiation, the use of compositions to reduce the using dosage of pesticide, reduce drug cost, extend the service life of medicament wheat powdery mildew after prothioconazoles and bupirimate mixture, decrease the pesticide adverse effect to ecological environment.
Description
Technical field
The bactericidal composition that the present invention relates to, is with prothioconazoles and bupirimate as effective ingredient, is suitable for
In preventing and treating wheat powdery mildew.
Background technology
Prothioconazoles, english common name prothioconazole, prothioconazoles is triazole type wide-spectrum bactericide,
It is mainly used in preventing and treating numerous diseases such as cereal crop such as Semen Tritici aestivi, Fructus Hordei Vulgaris, Brassica campestris L, Semen arachidis hypogaeae, Oryza sativa L. and legume crop
Evil.Youngster has good prevention effect to all wheat and barley diseases, as Semen Tritici aestivi and the powdery mildew of Fructus Hordei Vulgaris, banded sclerotial blight,
Droop, leaf spot, rust, sclerotiniose, net blotch, moire disease etc..Oil Lay and the soil of Semen arachidis hypogaeae can also be prevented and treated
Pass disease, such as sclerotiniose, and main foliage disease, as gray mold, melasma, brown spot, balck shank,
Sclerotiniose and rust etc..
Bupirimate is the ester type compound of ethirimol, belongs to heterocyclic nitrogen-group fungicide together, and powdery mildew is had specially good effect.
The present inventor is found by experiment that, prothioconazoles and bupirimate are at 30:1～1:30 proportion
Interior have obvious potentiation to wheat powdery mildew, completes the present invention after further study.
Have no the report that prothioconazoles is compounding with bupirimate at present.
Summary of the invention
It is prothioconazoles and the potentiation of bupirimate is killed that the purpose of the present invention aims to provide a kind of effective ingredient
Bacteria composition.
The present invention is achieved through the following technical solutions:
A kind of bactericidal composition preventing and treating wheat powdery mildew, including usual auxiliaries, prothioconazoles and ethirimol sulfonic acid
Ester, the mass fraction of prothioconazoles and bupirimate is than for 30:1～1:30, prothioconazoles and ethirimol
Sulphonic acid ester total mass fraction percentage composition in bactericidal composition is 3%～90%.
The composition pesticide of the present invention can according to well known to a person skilled in the art method, be configured to suspending agent,
The application forms of the applicable agricultural use such as water dispersible granules.
The composition pesticide of the present invention is possibly together with the usual auxiliaries of pesticidal preparations, including solvent, emulsifying agent, moistening
Agent, stabilizer, dispersant, thickening agent, defoamer, antifreezing agent, disintegrating agent, binding agent, filler, fill out
One or more mixing in material, medium etc., are known substance, are various auxiliary agents conventional in pesticidal preparations,
Can be varied from according to different situations, be not particularly limited.
The composition pesticide of the present invention, for preventing and treating plant disease agriculturally, is particularly useful for preventing and treating Semen Tritici aestivi white lead
Sick.
The composition pesticide of the present invention, should use in disease generation early stage or disease early period of origination when application.
The composition pesticide of the present invention, generally uses the method for spraying to use, it is also possible to use agricultural as required
Other of upper application use technology.
The bactericidal composition of the present invention, has good preventive effect, especially powdery mildew of cereals to by various wheat and barley diseases,
And having delayed drug-fast generation, the lasting period is long, decreases dosage and access times, cost-effective, uses
Convenient, time and labour saving, and reduce the pollution to environment.
Accompanying drawing explanation
Fig. 1 is that the synergism of wheat powdery mildew is surveyed and theoretical equivalent line by prothioconazoles with ethirimol.
Detailed description of the invention
In order to be more fully understood that the essence of the present invention, it is described further by following example, but the present invention is also
It is not limited to these embodiments.In these embodiments, unless otherwise indicated, all percentage ratios are weight percent
Ratio.
Embodiment one: the Toxicity Determination of wheat powdery mildew is tested by prothioconazoles and ethirimol mixture.
Table 1, the prothioconazoles ethirimol Toxicity Determination result of the test to wheat powdery mildew.
The synergism of wheat powdery mildew is surveyed and theoretical equivalent line (Fig. 1 by Fig. 1, prothioconazoles and ethirimol
Data come from table 1).In Fig. 1: A is the consumption (unit: g.ai./ha) of ethirimol, and B is prothioconazoles
Consumption (unit: g.ai./ha), C for actual measurement equivalent line, D be theory equivalent line.
As shown in Figure 1, actual measurement equivalent line series 1 under theoretical equivalent line series 2, ethirimol and prothioconazoles
Compound and wheat powdery mildew is shown obvious potentiation.
Embodiment two: 40% prothioconazoles ethirimol suspending agent.
Prothioconazoles 20%, ethirimol 20%, lignosulfonates 3%, calcium dodecyl benzene sulfonate 3%, xanthan
Acid glue 0.1%, empgen BB 5%, fatty alcohol-polyoxyethylene ether 6%, glycerol 5%, arabic gum
0.1%.Deionized water complements to 100%, is pulverized the most in advance by above-mentioned formula, adds sand mill
Middle grinding, after high shear mixing, allotment prepares 40% prothioconazoles ethirimol suspending agent.
Embodiment three: 60% prothioconazoles bupirimate water dispersible granules
Prothioconazoles 15%, bupirimate 45%, sodium lauryl sulphate 7%, dispersant lignin sulfonic acid
Salt 4%, disintegrating agent sodium chloride 3%, binding agent Polyethylene Glycol 3%, stable meltable starch 3%, Kaolin is supplied
To 100%.By above-mentioned formula dry pulverization process in proportion, pelletize, be dried, screening is made and is i.e. obtained 60% rosickyite bacterium
Azoles bupirimate water dispersible granules.
In sum, prothioconazoles is compounding with bupirimate rationally, and this bactericidal composition is to wheat powdery mildew
There is obvious potentiation, can be the dosage form agriculturally commonly used with excipient, there is preferable application prospect.
