Problems solved by technology

[0002] At present, although chemically synthesized pesticides are still an important means of preventing and controlling crop diseases and insect pests because of their good control effect and fast speed, they are widely used, but due to unreasonable abuse or their own problems, serious negative effects have been produced. 3R” problem: Pesticide residues (Residue) cause environmental pollution and damage the health of humans and animals. Nowadays, the incidence of serious diseases such as cancer, cardiovascular disease, and liver disease in humans has increased significantly, which is not unrelated to environmental pollution; chemical pesticides are also prone to drug resistance (Resistance), thus making it difficult to control pests and diseases; chemically synthesized pesticides are highly lethal to natural enemies, destroying the ecological balance, and easily causing pests and diseases to become rampant again (Resurgence)
According to new investigations, there is no report on the use of blue eucalyptus and atractylodes as plant pesticides at home and abroad

Abstract

The invention discloses a plant pesticide and its preparation method. The plant pesticide comprises the following components of: by weight, 1-30% of eucalyptole mother liquor, 5-20% of an emulsifier and the balance being anhydrous ethanol. The preparation method comprises the following steps of: preparing of the eucalyptole mother liquor and mixing. Based on a lot of indoor screening, traditional Chinese herbal medicines such as rhizoma atractylodis and the like are used as the main raw materials according to the proportion of Eucalyptus globulus to extract and process mother liquor, followed by the addition of auxiliary agents such as the emulsifier, anhydrous ethanol and the like. The plant pesticide provided by the invention is the first design at home and abroad; and reagents used have little toxicity and are environmentally friendly and safe when in use.
