Problems solved by technology

[0010] Although aluminum triethylphosphonate has a good two-way conduction function, its bactericidal spectrum is relatively narrow, and due to the long-term use of a single agent, the amount of application is constantly increasing, which not only increases the cost of farmers' use, but also increases the resistance. risk

Abstract

The invention relates to a bactericidal composition containing boscalid and fosetyl-aluminium and application of the bactericidal composition. The composition contains the boscalid and the fosetyl-aluminium in a weight ratio of (2-50):(2-49). The composition can be applied to disease control of cereal crops, melons, fruits, vegetables and the like. The composition has the advantages of wide application range, good effect, low cost, small residue, and safety for human, animals, environment and the like.

Description

(1) Technical field [0001] The invention relates to a fungicidal composition and its application, in particular to a fungicidal composition containing boscalid and aluminum triethylphosphonate, which is mainly used for the prevention and treatment of cereal crop diseases. (2) Background technology [0002] boscalid [0003] English common name: Boscalid [0004] Chemical name: 2-Chloro-N-(4′-chlorobiphenyl-2-yl)nicotinamide [0005] Structural formula: [0006] [0007] Boscalid is a new type of nicotinamide systemic fungicide newly developed in recent years. It has a wide bactericidal spectrum and is active against almost all types of fungal diseases. It is very effective for various rot diseases, and is also effective for other chemical-resistant bacteria. It is mainly used for the prevention and control of diseases including rapeseed, grapes, fruit trees, vegetables and field crops. Because of its unique mechanism of action, it is not easy to produce cross-resistan...
