Abstract
The invention relates to the field of pesticides and bactericides, and particularly discloses a bactericide composition containing pyraclostrobin and bromothalonil. Effective ingredients of the bactericide composition are the pyraclostrobin and the bromothalonil respectively, and the weight ratio of the pyraclostrobin to the bromothalonil is 1:79-79:1. The bactericide composition containing the pyraclostrobin and the bromothalonil has the advantages that problems that control effects of pyraclostrobin and bromothalonil to diseases such as downy mildew, anthracnose and the like of crops are simple, persistence periods of the pyraclostrobin and the bromothalonil are short and the like are solved; insecticide resistance is delayed, the persistence period of the bactericide composition is prolonged, and the bactericide composition is low in cost; and the bactericide composition can be manufactured into different formulations, realizes an excellent control effect for various diseases such as scab, the anthracnose, powdery mildew, the downy mildew, leaf spots, brown rot, white rot, botrytis and the like of various fruit trees and vegetables, and is particularly good in control effect for cucumber downy mildew, cucumber powdery mildew, apple anthracnose, watermelon anthracnose and the like.
Description
(1) Technical field [0001] The invention relates to the field of pesticide fungicides, in particular to a compound fungicide composition containing pyraclostrobin and brothylenil. (2) Background technology [0002] Pyraclostrobin (English common name: Pyraclostrobin), also known as Kairun, belongs to the methoxyacrylate fungicides, and its chemical name is N-2-1-(4-chlorobenzene)-1H-pyrazole-3- Methyloxymethylbenzene-N-methoxycarbamate, molecular formula: C 19 h 18 ClN 3 o 4 , molecular weight: 387.82, structural formula: [0003] [0004] Although pyraclostrobin can prevent and treat plant diseases caused by fungal pathogens such as Ascomycetes, Basidiomycetes, Deuteromycetes, and Oomycetes, pyraclostrobin has a single action site. If it is used alone for a long time, it cannot Avoidance will produce resistance, and the cost of the agent is high, making it difficult to promote plant protection. [0005] Bromothalonil (common name in English: Bromothalonil) is also ...
