Abstract
The invention discloses a bactericidal composition comprising fluoazole active ester and triazoles. The bacterial composition comprises an active ingredient A and an active ingredient B. The active ingredient A is selected from fluoazole active ester; the active ingredient B is selected from any one of the following compounds: tebuconazole, hexaconazole, epoxiconazole, difenoconazole, propiconazole and cyproconazole. A weight ratio of the active ingredient A and the active ingredient B is 1:80-60:1. The bactericidal composition has relativel high activity on various diseases of many crops, is obvious in synergistic effect, and the bactericidal spectrum is increased. Moreover, the bactericidal composition has the characteristics of small dosage, rain wash resistance and obvious synergism.
Description
The application is divisional application, and original application is a kind of patent application " fluorine-containing azoles work of Shaanxi Meibang Pesticide Co., Ltd.
Change the bactericidal composition of ester and triazole type ", the Application No. 201210364619.1 of original application, original application day is
2012.09.26.
Technical field
The invention belongs to technical field of pesticide, the bactericidal composition being related to a kind of fluorine-containing azoles Acibenzolar with triazole type is in crop
Application in disease.
Technical background
Fluorine azoles Acibenzolar is that a class novel plant induces disease-resistant activator, and this kind of compound does not have bactericidal activity in itself, and
Live plant can induce plant produce to the resistance infecting germ.
Tebuconazole, hexaconazole, epoxiconazole, Difenoconazole, propiconazole, Cyproconazole all belong to triazole bactericidal agent, this kind of
Pathogen in addition to medicament oomycetes in Mastigomycotina is inactive, to Ascomycotina, Basidiomycotina and Deuteromycotina
All active, its mechanism of action is impact sterols biosynthesis, so that somatic cells film function is destroyed.
In the real process of agricultural production, controlling disease is easiest to generate the problem that the generation of disease drug resistance.No
Compounded with kind composition, be to prevent and treat the very common method of resistance disease.Heterogeneity is compounded, and is imitated according to practical application
Really, to judge certain compounding be synergy, plus and or antagonism.In most cases, the compounding effect of agricultural chemicals is all to add
And effect, really have synergistic effect compounding seldom, especially synergistic effect clearly, synergy ratio very high compounding just more
Few.Through inventor's research, find by fluorine azoles Acibenzolar and Tebuconazole, hexaconazole, epoxiconazole, Difenoconazole, propiconazole,
Cyproconazole is mutually compounding, has good synergistic effect within the specific limits, and about fluorine azoles Acibenzolar and Tebuconazole, own azoles
Alcohol, epoxiconazole, Difenoconazole, propiconazole, Cyproconazole are related compounding, at present at home and abroad there is not yet relevant report.
Content of the invention
The purpose of the present invention is to propose to a kind of have the fluorine-containing azoles activation that synergistic function, use cost are low, preventive effect is good
Ester and the bactericidal composition of triazole type.
The present invention is to be achieved through the following technical solutions:
A kind of fluorine-containing azoles Acibenzolar and the bactericidal composition of triazole type, containing active component a and active component b, activity becomes
Divide a with active component b weight than for 1: 80～60: 1, described active component a is selected from fluorine azoles Acibenzolar, and active component b is selected from
One of Tebuconazole, hexaconazole, epoxiconazole, Difenoconazole, propiconazole, Cyproconazole；It is preferably active component a and activity
The weight of composition b is than for 1 60～40 1；More preferably fluorine azoles Acibenzolar and the weight of Tebuconazole are than for 1: 25～10: 1, fluorine azoles
The weight of Acibenzolar and hexaconazole is than for 1: 20～10: 1, the weight of fluorine azoles Acibenzolar and epoxiconazole is than for 1: 25～10: and 1, fluorine
The weight of azoles Acibenzolar and Difenoconazole is than for 1: 20～10: 1, the weight of fluorine azoles Acibenzolar and propiconazole is than for 1: 25～10
: 1, the weight of fluorine azoles Acibenzolar and Cyproconazole is than for 1: 20～10: 1；It is most preferably the weight of fluorine azoles Acibenzolar and Tebuconazole
