Abstract
The invention relates to belladonna oil botanical bio-pesticide for controlling aphids and red spiders. The existing botanical bio-pesticide has complex production process and high cost. The raw material formula of the invention is as follows: 27.5-37.5 parts of castor 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 castor oil are crushed, and the solvent is added; the extract is emerged after multiple impregnation extraction and is subjected to hydraulic concentration until the solvent is volatilized so as to obtain castor oil mother liquor; 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 castor 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 Oleum Hyoscyami botanical biological pesticide and preparation method thereof.
Background technology
Aphid [black peach aphid Myzus persicae (Sulzer), melon aphid Aphis gossypii Glover, cabbage aphid Brevicorynebrassicae (L.), radish aphid Lipaphis erysimi (Kaltenbach) etc.], two spotted spider mite [Tetranychus cinnabarinus Tetranychuscinnabarinus (Boiduval), truncate leaf mite T.truncates Ehara and Tetranychus urticae T.urticae Koch etc.] are the primary pests of harm vegetable category crop; along with the continuous expansion of global warming and protection ground area under cultivation, its harm that causes is serious year by year.At first high temperature can make it that radix takes place increases, take place to increase from generation to generation, and the place that protection ground has become insect to survive the winter in a large number and breed in the winter time.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.
Henbane is a kind of biennial herb plant, and its plantation applicability is very extensive, in China northeast, northwest and North China distribution is arranged all, the main product Inner Mongol, Hebei, Henan and northeast, North Western Provinces district.Contain hyoscyamine (hyoscyamine), atropine (atropine), hyoscine (scopolamine), 1-hyoscine compositions such as (atroscine) in the henbane, has stronger toxicity, it itself is exactly a kind of natural insecticide of good wide spectrum, adopt the carrier of Oleum Hyoscyami as all kinds of agricultural chemicals, not only to the person poultry harmless, non-environmental-pollution, the drug effect of the institute's compatibility agricultural chemicals that also can double.Use Oleum Hyoscyami to prepare the existing at home research of agricultural chemicals, " the 25% tropane alkali emulsion " as Institute of Botany, Chinese Academy of Sciences's development has stronger lethality to aphid, cotton bollworm, cabbage caterpillar etc., and insect population goes down rate more than 90%.Eliminate aphis and the botanical biological pesticide of two spotted spider mite but be that being exclusively used in of developing of mother liquor is anti-with the Oleum Hyoscyami, do not appear in the newspapers both at home and abroad.
Oleum Hyoscyami emulsion 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 henbane 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 150-200kg; with the oil yield of solvent extraction up to 23.5%; 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:
Oleum Hyoscyami 27.5-37.5 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 or ethanol or n-butanol or isopropyl alcohol or benzene or toluene or dimethylbenzene or dimethyl sulfoxide (DMSO) (DMSO) or dimethyl formamide (DMF) or the cyclohexanone for use.
Emulsifier select for use 2201 1601 or 0201B or 0203B 127 or 103 or 700# or 500# or OP-10 in a kind of, multiple.
Bleeding agent is selected a kind of in penetrating agent BX or penetrating agent JFC or azone or thiophene ketone or penetrant t or the organosilicon bleeding agent for use.
Antifreeze is selected a kind of in ethylene glycol or propane diols or urea or ammonium sulfate or glycerine or sodium chloride or the calcium chloride for use.
Its preparation process is as follows:
(1) the henbane 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 the Oleum Hyoscyami mother liquor after solvent evaporates is finished.
(2) in the Oleum Hyoscyami mother liquor, add dissolution with solvents under the normal temperature condition, add emulsifier, bleeding agent and antifreeze again, promptly get Oleum Hyoscyami emulsion finished product after mixing.
Oleum Hyoscyami botanical biological pesticide provided by the invention has following effect:
1, good drug efficacy, can hold concurrently and prevent aphid and the two spotted spider mite of harm vegetable category crop, 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 83.07% and 80.54% behind 400 times of liquid medicines of this emulsion dilution, the 3rd day preventive effect is respectively 87.50% and 82.91% behind the medicine, the 7th day preventive effect is respectively 77.60% and 75.41% behind the medicine, is better than the preventive effect of 2000 times of liquid of 20% fenvalerate missible oil to cotten aphid.
2, pharmacy is with low cost, and the primary raw material of Oleum Hyoscyami emulsion 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, use agricultural chemicals of the present invention, can reduce the access times and the using dosage of chemical pesticide significantly, effectively reduce the persticide residue in the melon dish, preserve the ecological environment, promote agricultural product quality and safety.
