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. In recent years, the aquaculture area of ​​lakes, rivers, sea areas, reservoirs, and paddy fields in China has gradually expanded, and the departments of agriculture, fishery, and water conservancy are all involved in aquaculture. Except for the Qinghai-Tibet Plateau, freshwater fish are cultivated in large areas in all provinces, municipalities and autonomous regions. China's marine aquaculture production has increased by more than 10% annually. In 2006, China's total export of aquatic products reached 8.97 billion US dollars. Facing an increasingly better market trend, some problems encountered in aquaculture need to be solved urgently, for example...

AI Technical Summary

Problems solved by technology

In the process of preventing and controlling parasites in aquaculture, a series of chemical preparations and chemical pesticides such as trichlorfon and potassium permanganate are used in large quantities, although this series of chemical preparations and chemical pesticides play an important role in the prevention and control of parasites in aquaculture. Playing an important role in the process, but there are still following problems: (1). The toxic and side effects of chemical preparations and chemical pesticides are relatively large, which may affect the health of consumers; (2). Chemical preparations and chemical pesticides in water bodies The natural degradation in the medium is slow, and the drug resistance of the target insects continues to increase, resulting in a vicious circle of increasing dosage; (3). Chemical preparations and chemical pesticides will cause drug residues in fish, shrimp, crabs, etc. in aquaculture to exceed the standard , has seriously affected the export of my country's aquaculture products and the international reputation of my country's aquatic products
