Problems solved by technology

At present, most of the insecticides in aquaculture are derived from pesticides and veterinary drugs, which are highly toxic and fast-acting. However, due to the lack of clinical experimental research related to aquaculture, to a certain extent, they are harmful to the safety of breeding animals, breeding environment and ecology. In addition, due to the unreasonable use of antibacterial fishery drugs, problems such as drug resistance of pathogenic bacteria and drug residues in aquatic products have occurred from time to time

Embodiment 1

[0024] An insecticide for fishing, comprising a main drug part and an auxiliary drug part, the main drug part is prepared by adsorbing furfural with ligninyl glycyrrhetinic acid gel, and the auxiliary drug part contains the following components in weight percentage: Buds subtilis Bacillus subtilis bacteria liquid 45%, onion 25%, oleander 10%, Tween 2.0%, glutathione 0.1%, and the balance is water.

[0025] The preparation method of above-mentioned fish insecticide comprises the following steps:

[0026] (1) Preparation of glycyrrhetinic acid succinate: 4.7g (10.0mmol) glycyrrhetinic acid was dissolved in 80ml of N,N-dimethylformamide, followed by adding 1.3g (10.0mmol) anhydrous potassium carbonate , 4.5g (45.0mmol) succinic anhydride and 1ml catalyst (prepared from pyridine and N,N-diisopropylethylamine at a volume ratio of 1:5), reacted in a dark room at 50°C for 6h, and cooled to At room temperature, add a large amount of water, then add ethyl acetate to extract, take the ...

Abstract

The invention relates to the technical field of veterinary drug preparation, particularly to an insecticide for fishing, and a preparation method thereof, wherein the insecticide contains a main drug component and an auxiliary drug component. The preparation method mainly comprises: preparation of glycyrrhetinic acid succinate, preparation of a lignin-based glycyrrhetinic acid gel, preparation of a main drug component, and preparation of an auxiliary drug component. According to the present invention, the microwave-assisted prepared lignin-based glycyrrhetinic acid gel is used to adsorb furfural, and can slowly release the adsorption on the furfural, and the auxiliary drug component can improve ecological balance, such that the toxic-side effect can be reduced and the influence on the ecological balance of the breeding pool water quality can be reduced during the insect disinfestation of the furfural, and the problems that the toxic-side effects of the insecticides in the traditional aquaculture are high, the fish production can be affected, the ecological balance of the water body is damaged, and the like can be solved.

Description

technical field [0001] The invention relates to the technical field of veterinary drug preparation, in particular to a fish insecticide and a preparation method thereof. Background technique [0002] With the rapid development of my country's aquaculture industry, the types and frequency of aquatic diseases have also increased rapidly. Drug control is one of the three major disease control technologies in my country's aquaculture industry, and it is also the most effective, economical and direct way in the prevention and control of aquatic animal diseases in my country. At present, most of the insecticides in aquaculture are derived from pesticides and veterinary drugs, which are highly toxic and fast-acting. However, due to the lack of clinical experimental research related to aquaculture, to a certain extent, they are harmful to the safety of breeding animals, breeding environment and ecology. In addition, due to the irrational use of antibacterial fishery drugs, problems...
