Description
Technical field
The invention belongs to crop disease control fields, and in particular to a kind of composite bactericide and its application.
Background technique
Cyproconazole is sterol demethylation inhibitors, by inhibiting Cytochrome P450 in pathogen sterol biosynthesis
C14 demethyl process, hinder the formation of fungal cell wall.Cyproconazole is systemic fungicide, has protection, treatment and shovel
Except effect.After application, Cyproconazole is quickly absorbed by plant, and is conducted to top.Cyproconazole action spectrum is wide, can effectively prevent work
By Septoria musiva (Septoria), beak spore bacterium (Rhynchosporium), tail spore bacterium (Cercospora), Ramularia on object
(Ramularia), the pathogens such as small mushroom (Mycena), sclerotinite (Sclerotinia), rhizoctonia (Rhizoctonia) are drawn
The disease risen, such as wheat powdery mildew, smut, banded sclerotial blight, snow mold, full rot, bunt, barley leaf blotch, dissipate it is black
Fringe disease, banded sclerotial blight, maize head smut, head smut of sorghum, stem rot of beet, coffee rust, alternaria leaf spot of apple and pears
Scab etc..It is worth mentioning that it is to soybean Asia rust preventive effect brilliance.The Cyproconazole lasting period is long, and prevention and treatment wheat rust is held
The effect phase is 4~6 weeks, and the prevention and treatment powdery mildew lasting period is 3~4 weeks.
Tebuconazole is triazole type sterilization pesticide, is sterol demethylation inhibitor, is at the seed for Important Economic crop
Reason or the efficient germicide of foliage spray, can effectively prevent a variety of rust, powdery mildew, net blotch, root-rot of cereal crop
Disease, head blight, smut and kind pass zonate spot and Rice shealth blighy etc..
Individual Cyproconazole or Tebuconazole all have certain effect in prevention and treatment corps diseases, and long-time service is easily led
Pathogenic evil develops drug resistance.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of composite bactericide and its application, to multiple kinds of crops disease
