Abstract

The invention discloses a plant source acaricide. The plant source acaricide is characterized by being prepared from the following raw materials in parts by weight: 22 to 35 parts of castor-oil plant, 22 to 35 parts of lightyellow sophora root, 20 to 30 parts of fructus arctii, 20 to 30 parts of herba asari, 15 to 20 parts of rhizoma acori graminei, 15 to 20 parts of flos caryophylli, 15 to 20 parts of rhizoma curcumae longae, 15 to 20 parts of herba artemisiae annuae, 5 to 8 parts of solvent, 1 to 5 parts of emulsifying agent and 80 to 100 parts of water. A formula is selected from plants and has wide source and low cost; in addition, all the raw materials are complementary to each other, and good insecticidal efficacy is realized.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a botanical acaricide and a preparation method thereof. Background technique [0002] Botanical pesticides refer to pesticides that use biologically active plants or specific parts thereof, and rough process or extract their active ingredients to make preparations for the prevention and control of harmful organisms. As an important part of biopesticides, botanical pesticides are highly effective, low-toxic or non-toxic, low-residue, high-selectivity, it is generally difficult for harmful substances to develop resistance to them, and they are easy to mix with other pesticides. It has the advantages of low cost, no pollution to the environment, independent degradation pathway, and safety to humans and animals. It is widely valued by pesticide research and application departments all over the world, and it is an important aspect of pesticide research and development today. [00...
