Abstract

The invention discloses a bactericidal composition containing picoxystrobin and thiocarbamates. The bactericidal composition comprise an active component A and an active component B, wherein the active component A is selected from picoxystrobin, and the active component B is one selected from the following bactericides: mancozeb, propineb, zineb and metiram; and a weight percentage of the active component A to the active component B is 1-60%:1-80%. The composition of the invention can prevent a plurality of crop diseases, such as downy mildew, leaf spot, rust, epidemic disease, venturia inaequalis, alternaria leaf spot, anthracnose, powdery mildew, physalosporapiricola, scab disease and leaf blight, has obvious synergism, and is quite safe to crops. Besides, the bactericidal composition has advantages of resistance to rain wash, lasting drug effect and small drug dose.

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 thiocarbamate. Background technique [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. . Contents of the invention [0003] Long-term use of a single dose of picoxystrobin may cause problems such as the occurrence of resistance and the decline in drug efficacy. The present invention proposes a bactericidal composition containing picoxystrobin and thiocarbamate, which is characteriz...
