Bactericidal composition

Abstract

The invention provides bactericidal composition. The bactericidal composition contains following active components: amisulbrom and fluopyram in a ratio being 50:1-1:50 in percentage by weight. The invention further relates to an application of the bactericidal composition to control of downy mildew, late blight, leaf spot disease, sheath blight, gray mold, powdery mildew, drooping disease, soft rot, northern blight, anthracnose, green mold, scab, alternaria leaf spot, bacterial wilt disease, black spot and southern blight. Furthermore, the invention relates to an application of the bactericidal composition to control of pathogenic or saprophytic fungi and bacteria in soil or culture media when the bactericidal composition is applied to a location requiring control and further relates to anapplication of the bactericidal composition to seed treatment so as to protect seeds from invasion of plant pathogens carried by the seeds.

Description

technical field

[0001] The invention relates to a bactericidal composition; the invention also relates to a method for using the bactericidal composition to control harmful fungi. Background technique

[0002] At present, for the prevention and control of diseases that are prone to resistance in agriculture, it is the best choice to use pesticide varieties with different action mechanisms for mixing. The effect of a single dose. Fungicides containing a single active ingredient often have certain defects in the prevention and control of agricultural diseases. Continuous repeated use not only makes pathogenic bacteria prone to drug resistance, but also easily causes pollution to food and the environment. Reasonable mixing of active ingredients in fungicides The above disadvantages can be overcome. The synergistic effect of the active ingredients through reasonable compounding can improve the control effect, reduce the amount of active ingredients, save costs, delay the emerg...
