Abstract
The invention relates to purple Datura stramonium oil botanical bio-pesticide. The existing botanical bio-pesticide has complex production process and high cost. The raw material formula of the invention is as follows: 30-40 parts of purple Datura stramonium oil, 20-50 parts of solvent, 15-30 parts of emulsifier, 0.5-3 parts of penetrator and 1-5 parts of antifreeze. The seeds of purple Datura stramonium are crushed to 30-50mesh, and the solvent is added; the extract is emerged after multiple impregnation extraction and is subjected to vacuum concentration under the pressure of minus 0.06Mpa at a temperature of 45DEG C until the solvent is volatilized so as to obtain the purple Datura stramonium oil; and the solvent is added to be dissolved again, and the emulsifier, the penetrant, and the antifreeze are added to be evenly mixed so as to obtain a purple Datura stramonium oil emulsion finished product. The invention has simple processing technology and low cost, and is suitable for industrial production, the emulsion has good quick effect and long lasting period, can significantly reduce the use number and use dosage of the chemical pesticide, effectively reduces the pesticide residue quantity of melons and vegetables, protects the ecological environment, and promotes the quality and safety of agricultural products.
Description
Technical field
The present invention relates to prevent and treat the botanical biological pesticide field of vegetable category crop aphid and two spotted spider mite, relate in particular to prescription of a kind of datura biopesticide and preparation method thereof.
Background technology
Aphid [black peach aphid Myzus persicae (Sulzer), melon aphid Aphis gossypii Glover, cabbage aphid Brevicorynebrassicae (L.) and radish aphid Lipaphis erysimi (Kaltenbach) etc.] and two spotted spider mite [Tetranychus cinnabarinus Tetranychus cinnabarinus (Boiduval), truncate leaf mite T.truncates Ehara and Tetranychus urticae T.urticaeKoch etc.] are the primary pests of harm vegetable category crop; along with the continuous expansion of global warming and protection ground area under cultivation, it is serious year by year that harm takes place for it.High temperature can make it that radix takes place to be increased, take place to increase from generation to generation, and the place that has become insect to survive the winter in a large number and breed in the winter time with protecting.Secondly, in the cultivation of protection ground, outside pest natural enemy often is isolated in, effect out of hand and make the insect breeding rapider.Because it is many that its year, algebraically took place, generation overlap needs in the production repeatedly to prevent and treat just and can prove effective.Long-term a large amount of chemical pesticide that uses causes it that some chemical pesticide (as decis, sumicidin, Imidacloprid etc.) is developed immunity to drugs, and field efficacy significantly reduces.Mini pest such as aphid and two spotted spider mite has become at present and has been difficult to the object prevented and treated in the production.
The botanical biological pesticide active ingredient of China's registration at present has kind surplus matrine, nicotine, rotenone, the pyrethrin etc. 10, be used for the anti-active ingredient that eliminates aphis 5 kinds of matrine, oxymatrine, nicotine, jervine, pyrethrins etc. are arranged, the active ingredient that is used to prevent and treat two spotted spider mite has only 3 kinds of matrine, nicotine and rotenone, and the active ingredient of can hold concurrently anti-aphid and two spotted spider mite also is above-mentioned 3 kinds.And matrine, nicotine and trifoliate jewelvine alkali are limit because of its raw material is subjected to planting area, resource-constrained, and price is high.
Datura is distributed widely in temperate zone, the world to the torrid areas, wherein datura how wild by field, ditch, place such as limit, road, riverbank, hillside, raw material is easy to get.Traditional Chinese medicine studies show that the datura complete stool has severe toxicity, and its leaf, flower, seed all can be used as medicine, and flavor is hot warm in nature, property of medicine analgesia anesthesia, relieving cough and asthma.Cure mainly to cough on contrary asthma, the face and give birth to sore, prolapse of the anus and rheumatism, traumatic injury, also can make anaesthetic.Datura medically is being applied, but serves as basis preparation botanical biological pesticide with datura oil, does not appear in the newspapers both at home and abroad.Datura oil emu processing technology is easy, and is with low cost, and suitability for industrialized production has overcome a lot of botanical pesticide complex manufacturing, the higher drawback of cost.The datura well developed root system; drought-resistant and barren; can utilize waste mountain waste, house property behind the house, the road both sides implement artificial establishing in large scale; the per mu yield seed can reach about 200kg; with the oil yield of solvent extraction up to 20%; the suitability for industrialized production that so can be product provides raw material sources endlessly, has solved the contradiction of development of resources with protection wild resource, destruction ecotope effectively.
Summary of the invention
Purpose of the present invention is prescription of botanical biological pesticide emulsion that a kind of can hold concurrently anti-vegetable category crop aphid and two spotted spider mite are provided and preparation method thereof.
For achieving the above object, the present invention realizes by following technical scheme based on weight: datura oil 30-40 part, solvent 20-50 part, emulsifier 15-30 part, bleeding agent 0.5-3 part, antifreeze 1-5 part.
Solvent is selected a kind of, multiple in methyl alcohol, ethanol, n-butanol, isopropyl alcohol, benzene,toluene,xylene, dimethyl sulfoxide (DMSO) (DMSO), dimethyl formamide (DMF), the cyclohexanone for use.
Emulsifier selects 2201,1601 for use, a kind of, multiple among 0201B, 0203B, 127,103,700#, 500#, the OP-10.
Bleeding agent is selected a kind of in penetrating agent BX, penetrating agent JFC, azone, thiophene ketone, penetrant t, the organosilicon bleeding agent for use.
Antifreeze is selected a kind of in ethylene glycol, propane diols, urea, ammonium sulfate, glycerine, sodium chloride, the calcium chloride for use.
The datura oil botanical biological pesticide, its preparation process is as follows:
(1) the datura seed meal is broken to the 30-50 order, adds solvent, dipping extracts repeatedly, each solvent load is identical, and extraction time was respectively 24-72 hour, merges extract,-0.06Mpa, be evaporated under 45 ℃ of conditions and promptly get datura oil mother liquor after solvent evaporates is finished.
(2) in datura oil mother liquor, add dissolution with solvents under the normal temperature condition, add emulsifier, bleeding agent and antifreeze again, promptly get datura oil emu finished product after mixing.
Datura oil botanical biological pesticide provided by the invention has following effect:
(1) can hold concurrently aphid and the two spotted spider mite of anti-harm vegetable category crop have the advantages that quick-acting is good, the lasting period is long.Field control effectiveness test is the result show, the 1st day preventive effect to cotten aphid and two spotted spider mite (Tetranychus cinnabarinus) is respectively 89.72% and 84.28% behind 400 times of liquid medicines of this emulsion dilution, the 3rd day preventive effect is respectively 95.30% and 86.34% behind the medicine, the 7th day preventive effect is respectively 85.24% and 82.70% behind the medicine, is better than the preventive effect of 2000 times of liquid of 20% fenvalerate missible oil to cotten aphid.
(2) preparation cost is low, and raw material is easy to get.The primary raw material of datura oil emu derives from the manually plant of establishing in large scale, has solved domestic botanical pesticide leading products matrine agricultural chemicals effectively and has utilized wild plant resource and the contradiction of destroying ecotope.
(3) environmental pollution is little.Agricultural chemicals of the present invention is a biogenic pesticide, uses this emulsion to prevent eliminating aphis and two spotted spider mite, can reduce the access times and the using dosage of chemical pesticide significantly, effectively reduces the persticide residue in the melon dish, preserves the ecological environment, and promotes agricultural product quality and safety.
