Artemisia spp. fungicide and preparation method thereof

Abstract

The invention discloses an Artemisia ordosica Kraschen bactericide, which is prepared by adding auxiliary agents into an Artemisia ordosica Kraschen extract serving as the main component. And the prepared bactericide takes the form of a micro-emulsion or an emulsion in water. The Artemisia ordosica Kraschen bactericide of the invention is safe to the environment. The active compounds in the Artemisia ordosica Kraschen bactericide are naturally existing substances coming from the nature, and form an immanent energy and substance circulating and metabolic path during the long-term evolution process, so application of the Artemisia ordosica Kraschen bactericide leaves no residue and results in little biological concentration. The bactericide is also relatively safe to nontarget organisms. Different from conventional pesticides in terms of the mechanism of action to plant pathogens, the Artemisia ordosica Kraschen bactericide is not easy to develop drug resistance in pathogens after application. Able to prevent and treat the downy mildew and botrytis of fruit trees, vegetables and flowers, the botanical bactericide provided in the invention boasts substantial application and promotion value in organic agricultural product production and is a novel pollution-free bactericide.
