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

The aquatic animal method for producing insecticide

Technical field

The present invention relates to a kind of preparation method of aquatic animal medicine, particularly a kind of plant source aquatic animal method for producing insecticide.

Background technology

Expansion along with the growth of aquatic products volume of production and the scale of breed, the aquatic products exchange is frequent day by day between international, domestic each department, aquiculture disease is of a great variety, the also corresponding increase of the order of severity of outburst and morbidity, especially the end of spring and the beginning of summer Fish dactylogyrider, the parasite disease that Trichodina causes, cause bigger economic loss to breed.Therefore, parasite killing plays very important effect aspect the fish diseases preventing and treating, in occupation of the share of Aquatic product medicine about 1/3.Adopted the sick effect of chemical classes parasite killing control eliminating fish parasites pretty good, but As time goes on, Drug resistance constantly manifest in the past; This class medicine has the residual effect of accumulating in the aquatic animal body simultaneously, can cause the aquatic product quality problem.

Therefore, providing a kind of preparation simple, obvious results aquatic animal method for producing insecticide, is one of this field scientific research technical staff important difficult problem of being badly in need of solving.

Summary of the invention

The objective of the invention is to overcome above-mentioned weak point, a kind of reasonable recipe, simple, easy to use, the obvious results aquatic animal method for producing insecticide of preparation are provided.

The technical scheme that this utility model adopted is for achieving the above object:

A kind of aquatic animal method for producing insecticide is characterized in that implementation step is as follows:

(1) takes by weighing following various crude drug by weight: Herba Agrimoniae 200-500 part, Radix Sophorae Flavescentis 200-500 part, Melia azedarach L. 400-700 part;

(2) the total amount ratio 1:8-12 in medical material adds water, 45 ℃ hot-water soak 20-30 minute, decoct according to conventional method; Boiling back slow fire boiling for the first time 1.5 hours is filtered; Filtering residue adds the water boiling back slow fire boiling 1 hour of 6 times of amounts again, filters; Merge filtrate twice, and then filter, it is 1.05 that temperature is concentrated into relative density 40 ℃ of-50 ℃ of following filtrates;

(3) add weight concentration 95% ethanol, making final concentration contain the alcohol amount is 60%, stirs, and leaves standstill 24 hours;

(4) filter, filtrate recycling ethanol adds the aqueous solution after distilling, and temperature is concentrated into relative density with it under 40 ℃-50 ℃ be 1.05-1.20;

(5) above-mentioned concentrated solution is cooled to room temperature, is packed as the 500ml/ bottle.

When using preparation of the present invention, culture the consumption that product 200ml of the present invention is used in the pond, full pool spilling head for every mu of 1 meter of the depth of water; When being used for feeding, can mixing according to the consumption of every kilogram of bait adding 3ml preparation of the present invention and raise.Use preparation of the present invention can reach the anthelmintic of aquatic animal body surface, reach anthelmintic purpose in the body after can making aquatic animal picked-up bait again.

The characteristic of each crude drug and effect in the product of the present invention:

Herba Agrimoniae is the herb of Rosaceae herbaceos perennial Agrimony, and common first names has Herba silenes fortunei, Agrimony, Herba Salviae Chinensis etc., and is wild in China various places.Herb contains 5 kinds of agrimophols and 4 kinds of agrimonines.Nature and flavor hardship, flat, puckery is the agent of robustness astringing to arrest bleeding, has astringing to arrest bleeding, the parasite killing that detoxifies, function invigorates vital energy and reinforce the heart.Root and hibernaculum expelling tenia.

Radix Sophorae Flavescentis is a leguminous plant, the root system Chinese medicine of Radix Sophorae Flavescentis, and its bitter in the mouth is cold in nature, and GUIXIN, kidney,liver,spleen, intestinal warp have effects such as heat clearing and damp drying, antibiotic diuresis, parasite killing, are used for hematodiarrhoea, have blood in stool, eczema, skin pruritus etc.The active component of Radix Sophorae Flavescentis mainly is alkaloid and flavone compound.

Contain chemical compounds such as melianol, Melia azedarach L. ketone and daucosterol in the Melia azedarach L., bitter in the mouth, cold in nature, poisonous, be the good medicine of parasite killing dampness.Go into liver, spleen, stomach warp.Cure mainly ascarid, also can drive pinworm, it is held concurrently can heat clearing and damp drying.On veterinary clinic and crops, use morely at present,, it is used more and more widely owing to the noresidue of Chinese medicine own, have no drug resistance.

The invention has the beneficial effects as follows: the anthelmintic Chinese herbal medicine has natural sex, the ecotype, low toxicity, no medicine Drug resistance, no hazard residue as the control medicine of the endoparasite and ectoparasite of culturing fish and shrimp, multi-functional, prevention effect is definite, small investment, can gather materials on the spot characteristics such as harmless environmental protection.Reasonable recipe of the present invention complements each other, and preparation is simple, and prevention effect is very obvious.
