Description

A high-efficiency, low-toxicity, and environmental-friendly plant insecticidal extract 1. Technical field: The invention relates to an insecticidal and acaricidal plant extract, in particular to a plant insecticidal extract with high efficiency, low toxicity and environmental protection. 2. Background technology: Acaridosis is an ectoparasitic disease characterized by severe skin itching, severe skin inflammation and contact transmission caused by carnivorous mites parasitizing on the surface or in the epidermis of animals. Mites are ubiquitous in all parts of the world and occur seasonally, which can reduce the digestive and absorption functions of sick animals, reduce production performance and product quality, and even cause mass death of animals, and also threaten human health. Over the years, scientists have been working on research and seeking effective control methods. At present, the control of mites is mainly based on chemically synthesized drugs, and the result...
