Abstract

The invention relates to a bactericidal composition containing picoxystrobin and benzimidazoles, which comprises an active ingredient A and an active ingredient B. Wherein the active ingredient A is selected from picoxystrobin, the active ingredient B is one selected from carbendazim and thiophanate methyl, the ratio of the effective active ingredient A to the effective active ingredient B by weight is 1-50%: 1-80%. The effective active ingredients can prepare wettable powders, water dispersion granules, suspending agents and suspoemulsions by adding an auxiliary agent and an excipient. The bactericidal composition is used for preventing and treating scab, physalosporapiricola, alternaria leaf spot, anthracnose, head blight, rust disease, brown spot, scab disease, rice blast and powdery mildew. The bactericidal composition provided in the invention is capable of resisting rainwater, and has obviously synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing picoxystrobin and benzimidazoles on crop diseases. technical background [0002] Picoxystrobin, English common name: picoxystrobin, molecular formula: C 18 h 16 f 3 NO 4 , Chemical name: (E)-3-methoxy-2-[2-[6-(trifluoromethyl)-2-pyridyloxymethyl]phenyl]methyl acrylate. Picoxystrobin is a mitochondrial respiration inhibitor, which inhibits mitochondrial respiration through electron transfer between cytochrome b and c1. It is effective in controlling strains resistant to 14-demethylase inhibitors, benzamides, dicarboxamides and benzimidazoles. [0003] The long-term use of picoxystrobin single-dose will easily cause the disease to develop drug resistance, leading to problems such as increased dosage, reduced control effect, and shortened duration, which is not conducive to sustainable development of the environment. The ...
