Chinese medicinal composition for preventing and controlling parasite in aquiculture and preparation method and application thereof

Abstract

The invention relates to a Chinese medicinal composition for preventing and controlling parasite in aquiculture and a preparation method and application thereof. The Chinese medicinal composition comprises the following components in percentage by weight: 10 to 50 percent of lightyellow sophora root, 10 to 50 percent of pokeberry root, 10 to 40 percent of sessile stemona root and 5 to 20 percent of antifeverile dichroa root. The Chinese medicinal composition contains various effective components for killing the parasite, has no toxic and side effects, cannot have pesticide residue, has convenient use, low cost, high efficiency of killing the parasite and difficult occurrence of pesticide resistance, is easily decomposed and has no influence on environment.

Description

technical field [0001] The invention belongs to the field of insecticides, in particular to a traditional Chinese medicine composition for preventing and treating aquaculture parasites, a preparation method and an application. Background technique [0002] China is the country with the largest amount of aquaculture in the world.
