Abstract

The invention relates to a bacteriocidal composition and an application thereof. The bacteriocidal composition is characterized by comprising Boscalid (A) and at least one (B) selected from the following active components of a triazole bactericide: difenoconazole, propiconazole, tebuconazole, hexaconazole, flutriafol, epoxiconazole, tetraconazole, flusilazole, myclobutanil, cyproconazole, triazolone and diniconazole, wherein the mass ratio of A to B is (1:50)-(50:1). The composition can be applied to preventing and treating diseases of crops such as cereal crops, melons, fruits, vegetables and the like.

Description

(1) Technical field [0001] The present invention relates to a bactericidal composition and its application, specifically, the present invention relates to a bactericidal composition containing boscalid and at least one selected from triazole fungicides as active ingredients, and the bactericidal composition Use for preventing and controlling plant 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 crop...
