Common threewingnut root-containing Chinese medicinal composition for preventing and controlling parasites in aquaculture and preparation method thereof

Abstract

The invention relates to a common threewingnut root-containing Chinese medicinal composition for preventing and controlling parasites in aquaculture, a preparation method thereof and use thereof. The Chinese medicinal composition comprises the following components in percentage by weight: common threewingnut root 10-40, melia azedarach linn 10-30, lightyellow sophora root 10-40 and sessile stemona root 10-30. The Chinese composition of the invention contains a plurality kinds of parasite-killing active ingredients, is free from toxic and side effects and medicament residue, convenient in use, low in cost, high in parasite-killing efficiency and insusceptible of arousing medicament resistance and is an easily-degradable and environmentally-friendly Chinese medicinal composition for preventing and controlling diseases and parasites in aquaculture.

Description

technical field [0001] The invention belongs to the field of invention and preparation of insecticides, in particular to a traditional Chinese medicine composition containing tripterygium wilfordii for preventing and controlling aquaculture parasites and a preparation method thereof. Background technique [0002] China is a big fishery country. The total amount of aquatic products accounts for 1 / 3 of the world's total, and the amount of aquaculture ranks first in the world, accounting for 2 / 3 of the world's total. In recent years, the aquaculture area of ​​China's lakes, rivers, sea areas, reservoirs, and paddy fields 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 t...

AI Technical Summary

Problems solved by technology

In the process of preventing and controlling parasites of aquaculture diseases, a series of chemical preparations and chemical pesticides such as trichlorfon and potassium permanganate are widely used. The process plays an important role, but there are still the 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 The natural degradation in water is slow, and the drug resistance of target insects continues to increase, resulting in a vicious circle of increasing dosage; (3). Chemical agents and chemical pesticides will cause drug residues in fish, shrimp, crabs, etc. in aquaculture Exceeding the standard has seriously affected the export of my country's aquaculture products and the international reputation of my country's aquatic products
