Abstract
The present invention relates to an extraction technique for preparing extract of tobacco and its offal and a technological process for preparing the invented nuisanceless or less-nuisance effective pesticide emulsion for control of injurious insects of crops and control of mite. Said invention is made up by using the extract of the tobacco and chemical pesticide according to the mixing ratio of 1-3:1, and its effective content is up to 8-30%. Said invention is safe for human and animals.
Description
The present invention relates to the extractive technique of insecticidal synergistic tobacco extract and the tobacco extract that produces with this technology and the compounded technology of chemical insecticide.
Tobacco is a kind of ancient pesticide plant, with its plant itself and make methods such as nicotine sulphate and once be used for crop insecticide.Noresidue hidden danger in environment.But tobacco itself and nicotine sulphate preparation fail to widely apply because of its poor benefit and more high shortcoming of toxicity in using, and the cause harm mite class effect of plant of control is relatively poor.
Pyrethroid insecticides (comprising sumicidin, decis, cypermethrin, cyfloxylate, Cyhalothrin and first Flumethrin etc.) is a class to various pests quick-acting better and the insecticide lower to higher mammal toxicity, but since various pests to its produced the height resistance and agricultural cost height, many kinds have limited the application of this insecticides to a great extent to the shortcoming of the mite class control efficiency difference of the various crop that causes harm in addition.
Profenofos (O-[4-bromo-2-chlorphenyl]-S-n-pro-pyl thiophosphate) be the asymmetric organophosphorus ester insecticides of a kind of novel tertiary, many insects there is the better prevention effect, but, limited its use aborning because it is poor to insect quick-acting, evil mite effect is paid no attention to thought of the high shortcoming of agricultural cost.
The present invention finds:
One, with an organic solvent from tobacco or its offcuts (the waste tobacco fragment producing as cigar mill, offal disintegrating slag and the crude opium drawn by vacuum cleaner etc.), extracts the technology of tobacco extract as methyl alcohol, ethanol, chloroform, carrene, benzene, toluene and dimethylbenzene etc.
Related extractive technique is:
" reflux extraction " technology: the offcuts during tobacco after learn from else's experience dry and the pulverizing or cigar mill produce, the extractor (relating to single-action extraction and multiple extraction) of packing into, add raw material weight 1-10 organic solvent doubly, soak the back refluxing extraction, collect filtrate, after treating that the sample analysis chemical examination determines that extracts active ingredients finishes, merging filtrate and sample analysis are pressed nicotine (nicotine) or anabasine (anabasine) content constant volume.Then with waste residue heating recovery solvent.Waste residue can be made fertilizer.
" cold casual method " extraction process: get the tobacco of dry and pulverizings or the cigar mill offcuts in the producing filter press of packing into, add raw material weight 1-10 above-mentioned solvent doubly, immersion is 1-72 hour after fully stirring, and carries out press filtration or centrifugal, collection filtrate.And then repeatedly in raw material, add an amount of solvent, soak a few hours and after stirring, carry out press filtration or centrifugal.Repeatedly filtrate merges, and collects supernatant through post precipitation and presses nicotine or anabasine content constant volume, and then with waste residue heating recovery solvent, waste residue can be made fertilizer.
Solvent involved in the present invention has: methyl alcohol, ethanol, chloroform, carrene, benzene, toluene and dimethylbenzene etc.
Two, the synergistic complex technology of tobacco extract and chemical insecticide.
The raw material that the present invention relates to has pyrethroid insecticides and organophosphorus ester insecticides such as the Profenofos etc. in tobacco extract and the insecticide.
This based composition can be processed into the missible oil that active constituent content reaches 8%-30% in proportion according to conventional method.
It is as follows that the technological process of missible oil is processed in the present invention, but be not limited thereto.
Raw material 1 (tobacco extract)---------metering
Raw material 2 (or 3,4 ... Deng.Chemical insecticide)---metering
Solvent 1---------------metering-modulation-sampling-discharging-packing-finished product
Solvent 2---------------metering
Emulsifier 1 (or 2,3 ... Deng)---------metering
Stabilizing agent---------------metering
Emulsifier involved in the present invention has QR-01, QR-03, QR-11, QNR-10 and farming breast 2201 etc.
The present invention is processed into missible oil and can further be illustrated by following " example ", below all umbers all refer to the active ingredient weight ratio.
2 parts of example 1 tobacco extracts
8 parts of sumicidins
1 48 parts of solvents
2 32 parts of solvents
8 parts of emulsifier
2 parts of stabilizing agents
It is processed into missible oil by above-mentioned flow process.3 parts of example 2 tobacco extracts
15 parts of Profenofos
1 47 parts of solvents
2 25 parts of solvents
8 parts of emulsifier
2 parts of stabilizing agents are processed into missible oil with it by above-mentioned flow process.2.5 parts of example 3 tobacco extracts
2.5 parts of beta-cypermethrins
1 47.5 parts of solvents
2 37.5 parts of solvents
8 parts of emulsifier
2 parts of stabilizing agents are processed into missible oil with it by above-mentioned flow process.Use above-mentioned example 1 related composition pesticide, the method of preventing and treating resistance apple yellow aphid, vegetable aphid and European red mite is: above-mentioned insect (mite) when taking place greatly, this composition pesticide is diluted with water to 1000-1500 times of liquid, connecing every adult fruit tree 5-7.5 kilogram soup the tree body is carried out even spraying, is 87.33-99.73% to the 3rd day control efficiency of apple yellow aphid; To the control efficiency of European red mite after the 10th day is 82.17-99.73%, and its effect all significantly is better than the effect of single same concentrations with 20% fenvalerate missible oil to this two insect, particularly the control efficiency of European red mite is higher than at double and singly uses this insecticide.
Use above-mentioned real side 2 related composition pesticides, prevent and treat above-mentioned insect (mite) effect and be better than example 1 related composition slightly, identical application method, the control efficiency of identical time to above-mentioned two fruit tree pest insects (mite) are respectively 89.61-99.32% and 93.87-99.85%.
Example 1 and 2 related composition pesticides have showed significant synergistic effect because of its different mechanism of action and mode of action to insect, and can reduce the generation of agricultural cost and pest resistance to insecticide greatly.
