Bactericide composition containing spiroxamine and methoxyl acrylate

Abstract

The invention discloses a bactericide composition containing spiroxamine and methoxyl acrylate. An active ingredient A in the composition is spiroxamine, and an active ingredient B is anyone of the following bactericides: azoxystrobin, kresoxim methyl, phenylate bacterium ester, pyraclostrobin and enestroburin, and the ratio in parts by weight of A to B is (60-1): (1-40). The bactericide composition disclosed by the invention can be used for preventing and controlling multiple crop diseases and has obvious synergic effect, a bactericidal spectrum is widened, activities on downy mildew, epidemic disease, anthracnose, powdery mildew, rust disease, alternaria leaf spot, leaf spot, scab disease, rice blast and the like are higher; meanwhile, application amount of pesticide is reduced, residual amount of the pesticide on crops is reduced, and environmental pollution is alleviated.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a fungicidal composition containing spirulina and methoxyacrylates. Background technique [0002] Fungi are the most important plant pathogenic bacteria, and more than 70% of plant diseases are caused by fungi. Because of the complex pathogenic factors, it is very difficult to control them. In recent years, with the adjustment of the rural planting structure, the planting area of ​​fruit trees has been increasing, and the occurrence of many fungal diseases on fruit trees has also increased, causing huge economic losses. [0003] Spiroxamine (Spiroxamine), molecular formula: C 18 h 35 NO 2 , English alias: N-Ethyl-N-propyl-8-tert-butyl-1, 4-dioxaspiro[4.5]dec-2-ylmethylamine. Spirulina is a substituted amine fungicide and a sterol biosynthesis inhibitor, which mainly inhibits the synthesis of C-14 deoxymethylase of pathogenic bacteria. The control objects are wheat powdery m...
