The invention discloses a novel use of 6-n-pentyloxyrheinic acid in control of saprolegniasis and ichthyophthiriasis, and further discloses a control agent containing the compound and a preparation method of the control agent. The control agent is composed of the following raw materials in percent by weight: 15%-50% of 6-n-pentyloxyrheinic acid, 5%-10% of a surfactant, 10%-30% of a dissolving agent and the balance of a solvent, wherein the sum of the raw materials is 100%. The preparation is low in toxicity to environment, unlikely to produce drug resistance, capable of effectively killing saprolegnia and ichthyophthirius multifiliis infected by fishes, has remarkable effects, and is simple in preparation process, low in production cost, simple in use method and convenient in promotion andapplication.
Description
technical field [0001] The invention belongs to the technical field of application of chemical products, and specifically relates to the application of 6-n-pentyloxyrhein in the prevention and treatment of saprolegniasis and melon worms of aquatic animals. technical background [0002] Small melon worm disease and saprolegniasis are common diseases in the process of aquaculture, which have caused huge economic losses to the aquaculture industry in our country. These two diseases have become one of the bottlenecks in the breeding process and seed breeding process, and their control technology has also become a hot spot and difficult problem in aquatic research at home and abroad. Malachite green, as a cheap and effective saprolegniasis control drug, is also often used in the treatment of small melon worms. However, because the drug has problems such as "three causes", high toxicity, and high residue, it was included in the "List of Veterinary Drugs and Other Compounds Prohib...
