Abstract

The invention discloses a bactericide composition. The bactericide composition is characterized by containing two active ingredients difenoconazole and propiconazol, wherein the weight ratio of the difenoconazole to the propiconazol is 1:2 to 2:1; and the composition contains 20 to 40 weight percent of active ingredients difenoconazole and propiconazol, and belongs to a systemic triazole bactericide with protection and control functions. The bactericide composition has the dual effects of preventing and controlling diseases and insects and adjusting the growth of crops, high systemic activity, broad spectrum and relatively longer persistence, and can reduce the cost of pesticide prevention and control, improve prevention and control effects and be widely applied to the prevention and control of middle-later diseases and insects of rice, in particular to the prevention and control of rice sheath blight.

Description

technical field [0001] The invention relates to a broad-spectrum fungicide composition, in particular to a fungicide composition containing two active ingredients of difenoconazole and propiconazole. Background technique [0002] Difenoconazole is a systemic bactericide with protective and therapeutic effects. With a wide spectrum of fungicides, foliar or seed treatment can improve crop yield and ensure quality. For Ascomycetes, Basidiomycetes and including Alternaria, Ascodiospora, Cercospora, Spirospora, Ballacne, Phoma, Septoria, Septoria, It has long-lasting protective and therapeutic effects on half-knowledge diseases including Scabella, powdery mildew family, rust fungus and certain kinds of transmitted pathogens. [0003] Propiconazole is a systemic triazole fungicide with protective and therapeutic effects. It can be absorbed by roots, stems and leaves, and can quickly conduct upwards in plants to prevent and control Ascomycetes, Basidiomycetes and Diseases caused...
