Abstract
The invention discloses application of scoparone as acaricide. Scoparone can be used for preventing and treating harmful mites like leaf mites by adding solvent or solubilizer or emulsifier. Compared with a traditional pesticide, the scoparone acaricide for plants has the characteristics and advantages that abundant scoparone exists in nature, especially in plants, and is low in toxicity, easy to degrade and safe to the environment; scoparone can be extracted through an ion exchange resin or supercritical CO2 extraction process, an extraction method is simple, and raw materials are easy to get; due to the physical and chemical characteristics, scoparone can be dissolved in kinds of solvent and easily mixed with other mite killing ingredients to be made into pesticides and can improve the mite killing effect. The harmonious pesticide is safe to people and livestock and environmentally friendly and has profound significance for long-term development of the ecological environment, heath of people and comprehensive treatment of diseases.
