Abstract
The invention discloses a composite bactericide containing trifloxystrobin. The composite bactericide is prepared by the following steps of: taking trifloxystrobin and difenoconazole or hexaconazole or propiconazole as active ingredients, wherein the mass ratio of the trifloxystrobin to the difenoconazole or hexaconazole or propiconazole is (1-30):(30-1); adding a normal amount of carriers and additives such as dispersing agents, stabilizing agents, wetting agents, anti-freezing agents and thickening agents; mixing to prepare a bactericidal suspending agent; and mixing to prepare the composite bactericide. The invention has the advantages that various ingredients in the composite bactericide have different action mechanisms, are mutually synergistic and reduce the drug resistance of pathogenic bacteria, so that the bactericidal effect of the composition is obviously better than the bactericidal effect of a single ingredient. Thus, the composite bactericide has synergistic action and wider bactericidal spectrum. The composite bactericide disclosed by the invention can be used for preventing and treating various diseases of various crops, mainly has a good effect on inhibiting leaf spot, anthrax and banded sclerotial blight, and can be used for crops including bananas, watermelons, cucumbers, tomatoes, hot peppers, rice, oranges and the like.
Description
technical field [0001] The invention relates to a pesticide, in particular to a compound fungicide containing trifloxystrobin. Background technique [0002] Trifloxystrobin is a new type of systemic fungicide successfully developed from the natural product Strobilurins as a fungicide lead compound. It has a good killing effect on Peronospora and Phytophthora fungi. However, when used alone, the duration of sterilization is short, and the disease prevention effect is not ideal. If it is made into a composition with some systemic or protective fungicides, their bactericidal effect has obvious synergistic effect. [0003] Difenoconazole (Difenoconazole) is a triazole fungicide with protective, curative and systemic activity against Ascomycetes, Basidiomycetes and other species including Alternaria, Ascodiospora, Cercospora, Infectious diseases of the genus Disposporum, Coccidioides, Phoma, Septoria, Septoria, and Scabella, and some pathogenic bacteria of the family Erysiphacea...
