Abstract
Present invention relates particularly to a kind of microbicide compositions for preventing and treating wheat root disease and its application, belong to bactericide technical field.The microbicide compositions for being used to prevent and treat wheat root disease include two kinds of active components of prothioconazoles and chlorine silicon tisocromide, and the mass ratio of the prothioconazoles and chlorine silicon tisocromide is 15:1~1:15.The microbicide compositions that the present invention is provided, preventing and treating to wheat root disease in specific ratio range has obvious synergistic effect, the microbicide compositions its prevention effect compared with single dose is significantly improved, and compensate for the narrow problem of single bactericide fungicidal spectrum, expands fungicidal spectrum.The risk that the single medicament of long-term use easily produces resistance can be effectively reduced using the microbicide compositions, extends the usage cycles of medicament, to the integrated control important in inhibiting of wheat root disease.The microbicide compositions have good plant tolerance under concentration used simultaneously, to crop safety.
Description
Technical field
The invention belongs to bactericide technical field, and in particular to a kind of antimicrobial combination for preventing and treating wheat root disease
Thing and its application.
Background technology
Wheat root disease is more obstinate disease in wheat diseases, the serious yield and quality for threatening wheat.Due to
The complexity of soil environment, very big challenge is brought to the preventing and treating of wheat root disease.Wheat root disease mainly includes wheat stalk
Basal stem rot, take-all and wheat sharp eyespot etc., its Main Pathogenic Bacteria include：Fusarium culmorum (F.culmorum), oat
Sickle-like bacteria (F.avenaceum), Fusarium graminearum (F.graminearum), false Fusarium graminearum
(F.pseudograminearum), fusarium acuminatum (F.acuminatum), Fusarium oxysporum (F.oxysporum) and scouring rush
Sickle-like bacteria (F.equiseti), take-all germ (Gaeumannomyces graminis), Rhizoctonia cerealis
And Rhizoctonia solani Kuhn (R.solani) etc. (R.cerealis).The medicament for being presently used for preventing and treating wheat root disease mainly has：It is many
On the one hand bacterium spirit, Tebuconazole, thiophanate-methyl, triazolone, Difenoconazole etc., these medicaments have single chemical control spectrum
It is narrow, it is difficult to control infecting for the various pathogens of wheat root, the defect of prevention effect difference is caused, on the other hand, due to connecting for many years
Continuous to use, pathogen has generated certain resistance to these medicaments, causes prevention effect not ideal enough.
