Dry powder preparation for preventing and controlling saprolegniasis of aquatic animals and preparation method thereof

Abstract

The invention discloses a dry powder preparation for preventing and controlling saprolegniasis of aquatic animals, which is characterized in that: the dry powder preparation consists of the following components in percentage by weight: 71 to 79 percent of biochemical fulvic acid, 10 to 15 percent of disodium metabisulfite and 10 to 15 percent of bronopol. A preparation method for the dry powder preparation for preventing and controlling the saprolegniasis of the aquatic animals is characterized in that: the method comprises the following steps: (1) putting the 10 to 15 percent of disodium metabisulfite and 10 to 15 percent of bronopol into a mixer for mixing for 5 minutes to obtain a two-component mixture; and (2) adding the 71 to 79 percent of biochemical fulvic acid to the mixed mixture in the mixer, and continuously mixing for 10 minutes to prepare the dry powder preparation for preventing and controlling the saprolegniasis of the aquatic animals, wherein the steps are all carried out at room temperature. The dry powder preparation mainly prevents and controls pathogenic fungi of aquatic products, also has good bacteriostatic and bactericidal effects on pathogenetic bacteria of the aquatic products, particularly on Gram negative bacteria, has the external effect of killing fungi and the bacteria and internal effects of adjusting organisms and strengthening immunity of the aquatic animals, and has the advantages of safe use and environmental protection.

Description

Technical field: [0001] The invention relates to a medicine for preventing and treating saprolegniasis of aquatic animals in aquaculture, in particular to a dry powder preparation for preventing and treating saprolegniasis of aquatic animals and a preparation method thereof. Background technique: [0002] Saprolegniasis is a disease caused by a filamentous fungus parasitic in aquatic animals. It harms a wide range of aquatic animals and is prevalent all over the country. It is one of the most common and serious diseases in aquaculture. , can cause greater losses to my country's aquaculture industry every year. The disease has been treated with "malachite green" in production for a long time, and it has a good curative effect. [0003] Malachite green (Malachite green) is also known as alkaline green, base block green, malachite green, molecular formula C 23 h 25 ClN 2 , is a triphenylmethane dye. Its main metabolite in aquatic organisms is colorless malachite green (leuc...

AI Technical Summary

Problems solved by technology

On the one hand, there is no drug with good curative effect available in production, which has caused serious economic losses to the farmers and the aquaculture industry, and even affected the healthy development of the aquaculture industry.

On the other hand, some farmers and unscrupulous traders took risks and continued to illegally use "malachite green", which caused serious hidden dangers to food safety and directly endangered public health safety; at the same time, it also affected the export of Chinese aquatic products
