example 1

[0087] Weigh 10.0g of magnolol, 5.0g of ethanol, and 80.0g of rapeseed oil, mix and stir until magnolol is completely dissolved, then add 2.0g of surfactant and 3.0g of transdermal agent, and mix well to obtain the fish-killing agent. Control agent for ectoparasitic protozoa.

example 2

[0089] The control agent for killing fish ectoparasites: magnolol 8.0g, ethanol 4.0g, rapeseed oil 85.0g, surfactant 1.0g, transdermal agent 2.0g, all the other are the same as example 1.

example 3

[0091] The control agent for killing fish ectoparasites: magnolol 12.0g, ethanol 6.0g, rapeseed oil 76.0g, surfactant 2.0g, transdermal agent 4.0g, all the other are the same as example 1.

Abstract

The invention discloses an application of magnolol in killing fish parasitic protozoa and a preparation thereof. As a pollution-free green novel fish drug, the magnolol brings low toxicity to fish, rarely generates drug resistance and can effectively kill in-vitro and in-vivo ichthyophthirius multifilis; the magnolol, ethanol and rapeseed oil are mixed and stirred until the magnolol is completely dissolved to obtain a mixed solution; a surfactant and a transdermal agent are added into the mixed solution; and then the mixture is stirred uniformly to obtain a control agent for killing fish parasitic protozoa, wherein the magnolol accounts for 6-12%, the ethanol accounts for 3-6%, the surfactant accounts for 1-3%, the transdermal agent accounts for 1-4% and the balance is the rapeseed oil. The production cost of the control agent is low, the application method is simple, and the promotion and application are promoted.

Description

technical field [0001] The present invention relates to magnolol (C 18 h 18 o 2 ), particularly relates to the use of magnolol in killing fish ectoparasites. Background technique [0002] In current fishery production, fish disease is one of the main obstacles to achieve high yield and high efficiency in aquaculture, among which fish parasitic diseases are the most common and most harmful fish diseases. According to statistics from the National Aquatic Products Central Station, parasitic diseases account for 24.58% of the 118 biologically-derived diseases of fish, among which fish parasitic protozoan diseases are the most prevalent and most harmful. Fish-parasitic protozoa include six phyla: Sarcomastigophora, Apicomplexa, Microspora, Ascetospora, Myxozoa and Ciliophora. Among them, trichomonas, multi-spored melon worms (abbreviated as small melon worms) and myxospores are species that are more harmful to fish, and have been reported all over the country and even around ...
