Embodiment 1

[0020] A preparation method of an insecticide for aquatic animals, the implementation steps are as follows:

[0021] Weigh various raw materials according to the stated parts by weight: Agrimony 250 kg, Sophora flavescens 250 kg, Neem 500 kg. According to the total ratio of raw materials 1:10, add water, soak in hot water at 45°C for 20 minutes, and decoct according to the conventional method; after the first boiling, decoct with slow fire for 1.5 hours, filter; add 6 times the amount of water to the filter residue after boiling Simmer for 1 hour, filter; combine the two filtrates, and then filter again, and concentrate the filtrate to a relative density of 1.05 at a temperature of 40°C-50°C; add 95% ethanol to make the final concentration alcohol content 60%, stir , stand still for 24 hours; filter, recover ethanol from the filtrate, add the distilled aqueous solution, and concentrate it to a relative density of 1.05-1.20 at a temperature of 40°C-50°C; finally, cool the conce...

Embodiment 2

[0024] Weigh various raw materials according to the stated parts by weight: Agrimony 400 kg, Sophora flavescens 500 kg, Neem 400 kg. Add water according to the total ratio of raw materials 1:8, soak in hot water at 45°C for 25 minutes, and decoct according to the conventional method; after the first boiling, decoct with slow fire for 1.5 hours, filter; add 6 times the amount of water to the filter residue after boiling Simmer for 1 hour, filter; combine the two filtrates, and then filter again, and concentrate the filtrate to a relative density of 1.05 at a temperature of 40°C-50°C; add 95% ethanol to make the final concentration alcohol content 60%, stir , stand still for 24 hours; filter, recover ethanol from the filtrate, add the distilled aqueous solution, and concentrate it to a relative density of 1.05-1.20 at a temperature of 40°C-50°C; finally, cool the concentrate to room temperature and pack it into 500ml / bottle.

[0025] Others are with embodiment 1.

Embodiment 3

[0027] Weigh various raw materials according to the stated parts by weight: Agrimony 500 kg, Sophora flavescens 350 kg, Neem 650 kg. Add water according to the total ratio of raw materials 1:12, soak in hot water at 45°C for 30 minutes, and decoct according to the conventional method; after the first boiling, simmer for 1.5 hours, filter; add 6 times the amount of water to the filter residue after boiling Simmer for 1 hour, filter; combine the two filtrates, and then filter again, and concentrate the filtrate to a relative density of 1.05 at a temperature of 40°C-50°C; add 95% ethanol to make the final concentration alcohol content 60%, stir , stand still for 24 hours; filter, recover ethanol from the filtrate, add the distilled aqueous solution, and concentrate it to a relative density of 1.05-1.20 at a temperature of 40°C-50°C; finally, cool the concentrate to room temperature and pack it into 500ml / bottle.

Abstract

The invention relates to a preparation method of an insecticide for aquatic animals, which comprises the following steps of: (1) weighing the following raw medicinal materials in parts by weight: 200-500 parts of hairyvein agrimony herbs, 200-500 parts of lightyellow sophora roots and 400-700 parts of melia azedarach linn; (2) adding water 8-12 times greater than the total amount of medicinal materials, soaking in 45 DEG C of hot water for 20-30 min, and decocting according to a conventional method; decocting with slow fire for 1.5 h after first boiling, and filtering; adding 6 times of water to filtration dregs, decocting with slow fire for 1 after boiling, and filtering; and combining two filtrates, filtering, and concentrating the filtrate at the temperature of 40-50 DEG C until the relative density becomes 1.05; (3) adding 95% alcohol by weight concentration to ensure that the alcohol content of the final concentration is 60%, stirring and settling for 24 h; (4) filtering, recovering alcohol from the filtrate, adding a distilled water solution, and concentrating at the temperature of 40-50 DEG C until the relative density becomes 1.05-1.20; and (5) cooling the concentrate to room temperature, and charging 500 ml / bottle. The insecticide has the advantages of reasonable formulation and simple preparation; and when being used for controlling insects inside and outside the aquatic animals, the insecticide has obvious effect.

Description

technical field [0001] The invention relates to a preparation method of an aquatic animal medicine, in particular to a preparation method of a botanical aquatic animal insecticide. Background technique [0002] With the growth of aquatic product production and the expansion of aquaculture scale, the exchange of aquatic products between international and domestic regions has become increasingly frequent, and there are many types of aquaculture diseases, and the severity of outbreaks and diseases has also increased accordingly, especially the ring of fish in late spring and early summer. Parasitic diseases caused by worms and trichotillomantes cause large economic losses to breeding. Therefore, insecticides play a pivotal role in the prevention and treatment of fish diseases, accounting for about 1 / 3 of the share of aquatic medicines. In the past, the use of chemical insecticides to control fish parasitic diseases was effective, but with the passage of time, drug resistance c...
