Problems solved by technology

Fluopyram is a special pesticide for the control of plant oomycete diseases, and pathogenic bacteria develop resistance to it very quickly. The amount of drug used alone is increasing, and when it is compounded with conventional agents, the resistance is increasing year by year after years of use. There is no literature report on the mixing of this kind of pesticides and todazole

Abstract

The invention relates to bactericidal composition containing amisulbrom and fluopicolide. The weight ratio of the two active ingredients is 20:1-1:20, the total content of the active ingredients in a bactericide is 2%-80% in percentage by weight, preferably 5%-70%, and the remaining is auxiliaries and carriers permissible in the pesticide. The composition has a significant synergistic effect, can reduce the use rate of pesticides and is environment-friendly and safe.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a fungicidal composition comprising indazolesulprofeslam and fluopyram. Background technique [0002] Plant oomycete disease is caused by the infection of pathogenic fungi of the subphylum Flagellate Oomycetes. There are many kinds of Oomycetes pathogenic fungi. They have a wide range of hosts and can cause diseases in plants such as vegetables, fruit trees, flowers, forest trees, cotton, hemp, grains, oil plants, and Chinese herbal medicines. , Liliaceae, Rutaceae, Grapeaceae, Fabaceae, Gramineae, Compositae, Cactaceae, Amaranthaceae, Chenopodiaceae and other hundreds of plants suffer from various diseases, such as damping-off, cotton rot, blight, cotton blight , downy mildew, white rust and root rot, stem rot, fruit rot and so on. These diseases are popular almost every year, causing great losses. Therefore, Oomycetes pathogenic fungi are very important pathog...
