Compound bactericide containing berberine and polyoxins and application thereof

Abstract

The invention relates to a compound bactericide which is compatible to environment, high in efficiency and low in toxicity and consists of berberine and polyoxins. The compound bactericide is particularly used for the application study of the prevention and control of plasmopara viticola. In a compound composite, a synergistic ratio of the berberine to the polyoxins is 1:2-1:16. The compound bactericide has outstanding performance in the aspect of the prevention and control of plasmopara viticola.

Description

technical field [0001] The invention relates to a compound fungicide, more specifically, the invention relates to a biological source fungicide used for preventing and treating grape downy mildew. Background technique [0002] For a long time, due to the large amount of chemical fungicides used in production to ensure the output and quality of agricultural products, there has been tremendous pressure on the ecological environment, and some pathogenic bacteria have rapidly developed drug resistance, further increasing the amount of fungicides, resulting in pesticide residues in agricultural products Seriously exceeding the standard, causing great harm to humans, animals and the environment. The development and utilization of bio-pesticide resources that are environmentally compatible and harmless to humans are increasingly favored by various countries. [0003] The active ingredients of biological pesticides are naturally occurring, generally non-toxic, easy to degrade, less...
