Abstract

The invention discloses an antiseptic composition containing bromothalonil and phenamacri. The antiseptic composition contains a commonly used additive, the bromothalonil and the phenamacri, wherein the mass part ratio of the bromothalonil to the phenamacri is 30: 1 to 1:30, the weight sum of the bromothalonil and the phenamacri is 0.01%-60% of the weight of the composition. After the bromothalonil and the phenamacri are compounded in certain proportion, the composition has the synergistic effect on pathogen fungi and is suitable for crop diseases caused by fungus prevention and control.

Description

technical field [0001] The fungicidal composition of the present invention uses bromothalonil and cyclostrobin as active ingredients, the composition has a synergistic effect on pathogenic fungi, and is suitable for preventing and treating fungal diseases of crops caused by pathogenic fungi, especially anthracnose crop anthracnose and crop sheath blight caused by Rhizoctonia solani and crop powdery mildew caused by pathogens of the powdery mildew family. Background technique [0002] Bromothalonil, English common name bromothalonil, chemical formula C 6 h 6 Br 2 N 2 , the chemical name is 1,2'-dibromo-2,4-dicyanobutane; bromothalonil is a broad-spectrum, low-toxicity, anti-mold, algicide, which can inhibit and eradicate bacteria, fungi and algae It has a good control effect on crop diseases, especially for anthracnose. [0003] Cyclostrobin belongs to 2-cyanoacrylate fungicides. This compound belongs to cyanoacrylates. It is highly efficient, slightly toxic, broad-spect...
