Abstract
The insecticide for treating fish's parasitic disease is prepared from SR-biological propene chrysanthemum monocarboxylate, sesame extrat-liquid and dimethyl benzene etc.. Compared with existing fish's insecticide, it has the advantage of high efficiency, low-toxity, high-security, simple preparation process and low cost etc., its effective rate of treating parasitic disease is up to 95%. It is suitable to every kind of cultured fish, having no side effect and capable of improving the water quality to build up fish's health.
Description
The present invention relates to a kind of medicine, especially relate to a kind of insecticide for the treatment of the eliminating fish parasites disease and preparation method thereof.
For a long time, the sick main chlorophos that relies on of China's treatment eliminating fish parasites, along with the increase of using the age, parasite also constantly strengthens its pesticide resistance, thereby treat concentration and also have to strengthen thereupon, even arrive original several times, so not only treat cost and heighten, and having increased the toxic and side effect of medicine to fish, especially most of famous-brand and high-quality breed varieties are met it and can not be survived.Publication number is the patent " fish and entomophagous parasite worm antagonist " of CN1044905A though also can treat parasitosis, and it needs industrialized production, produces comparatively complexity, and cost of manufacture is also very high, is unfavorable for penetration and promotion.
The object of the present invention is to provide a kind of efficient, low toxicity, safe, compound method is simple, cost is low insecticide for fish.
The object of the present invention is achieved like this: composition prescription of the present invention is (by weight percentage):
S
R-EXTHIN: 1～10% decis: 1～5%
Sesame extract: 0.1～0.5% dimethylbenzene: 85～95%
PHT antioxidant: 0.5～2%
Preparation method of the present invention is:
(1) clean sesame is soaked with acetone, uninterruptedly refluxed 24 hours, filter then, obtain the sesame residue of filtrate A and solid respectively.
(2) again the sesame residue is soaked with high concentration ethanol, uninterruptedly refluxed 24 hours, filter then, obtain liquor B and sesame residues respectively.
(3), after acetone and ethanol volatilization finish, the merging of two filtrates is promptly obtained the sesame extract with filtrate A and liquor B reduction vaporization respectively.
(4) with sesame extract and S
RAfter-EXTHIN, decis, dimethylbenzene mixed by a certain percentage, brute force stirred evenly again.
(5) said mixture is added again a certain proportion of PHT antioxidant, brute force stirs evenly and gets product again.
This insecticide is with vegetalitas deinsectization element (S
R-EXTHIN, decis) for active substance, to be aided with synergist (sesame extract), cosolvent (dimethylbenzene) etc. formulated, compares with traditional insecticide for fish, have the following advantages:
1, efficient: this insecticide consumption is few, and treatment concentration is 0.01ppm, and efficient is more than 95%, and chlorophos is 0.5～1ppm, and efficient is about 90%.
2, low toxicity: this insecticide is a vegetable insecticide, be applicable to the pest control of various cultured fishes, the fish body is had no side effect, and can improve water quality environment, strengthen fish physique, and chlorophos is mainly used in the pest control of conventional cultivation fish, and is very big to most of famous-brand and high-quality cultured fishes (as mandarin fish, butterfish etc.) side effect, so that can not survive.
3, safe: safety coefficient (half lethal concentration LD
50Ratio with working concentration), this insecticide is greater than 50, and chlorophos is less than 20.
4, compound method is simple: only needing can be formulated by general chemical physical method.
5, cost is low: this utilization of pesticides cost only is 1/3 of a chlorophos.
Below in conjunction with embodiment the present invention is described in further detail.
Clean sesame is soaked with acetone, uninterruptedly refluxed 24 hours, filter then, obtain the sesame residue of filtrate A and solid respectively.Again the sesame residue is soaked with high concentration ethanol, uninterruptedly refluxed 24 hours, filter then, obtain liquor B and sesame residues respectively.Again with filtrate A and liquor B reduction vaporization respectively, after acetone and ethanol evaporation finish, the merging of two filtrates is promptly obtained the sesame extract.
Embodiment 1:
Get 100 gram S respectively
R-EXTHIN, 44 gram decises, 1 gram sesame extract, 850 gram dimethylbenzene mix above-mentioned four kinds of materials then, stir evenly with Ultrasound Instrument again.And then add 5 gram PHT antioxidants, stir evenly with Ultrasound Instrument again and get product.
Embodiment 2:
Get 15 gram S respectively
R-EXTHIN, 10 gram decises, 5 gram sesame extracts, 950 gram dimethylbenzene, 20 gram PHT antioxidants, preparation method is with embodiment 1.
Embodiment 3:
Get 40 gram S respectively
R-EXTHIN, 50 gram decises, 3 gram sesame extracts, 900 gram dimethylbenzene, 7 gram PHT antioxidants, preparation method is with embodiment 1.
Claims (2)
