Abstract

The invention relates to a synergistic fungicidal composition, the active components of which contain kresoxim methyl and thiophanate methyl, wherein the weight ratio of the kresoxim methyl to the thiophanate methyl is 50:1 to 1:100. Additives and excipients can be added in the active components to produce wettable powder, water dispersible granule and suspending agent, which are mainly used to control the alternaria leaf spot, scab, ring spot and powdery mildew of fruit trees.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing kresoxystrobin and thiophanate-methyl to fruit tree diseases. technical background [0002] Kresoxim-methyl is a methoxyacrylate fungicide developed by BASF, Germany. Molecular formula: C 18 h 19 NO 4 , Chemical name: methyl (E)-2-methoxyimino-2-[2-(0-methylphenoxy)phenyl] acetate. [0003] Kresoxystrobin belongs to the mitochondrial respiration inhibitor, is a broad-spectrum fungicide with a long duration of action, and is effective against most diseases caused by pathogenic fungi such as Ascomycetes, Basidiomycetes, Deuteromycetes and Oomycetes. It has protection, treatment and eradication activities, is safe for crops, humans, animals and beneficial organisms, and basically has no pollution to the environment. However, the inherent resistance of this type of fungicide is high, and it is easy to produce resistance, and...
