Description
Technical field
The invention belongs to a kind of plant pesticide, be specifically related to a kind of broad spectrum vegetable insecticide and preparation method thereof.
Background technology
Along with people's growth in the living standard, have higher requirement for safety, high-quality and the feature of environmental protection of food, the demand of " pollution-free food " is increased day by day; In international trade, persticide residue how much, also becomes the green barrier of international food and Agricultural Products Trade.The agricultural chemicals of China's use at present belongs to the chemical reagent of synthetic more than 80%.Chemical pesticide toxicity is big, difficult degradation, and extensive the use more and more causes people's common concern for the destruction of ecotope.
Plant pesticide is a kind of novel agrochemical that damage by disease and insect is had preventive and therapeutic effect that utilizes plant corpus and plant matter extracts to make.It is long with efficient, low toxicity, drug effect phase, and basic noresidue and to characteristics such as person poultry safeties is progressively accepted by people.But plant pesticide exists recovery rate to hang down and the problem of poor stability.
Summary of the invention
The invention provides a kind of extractive technique of prescription and extract of broad spectrum vegetable insecticide, this invention has solved the problem of the low and plant pesticide poor stability of the recovery rate of plant pesticide main component.
A kind of broad spectrum vegetable insecticide and preparation method thereof, it is characterized in that: it is to be made by the following weight proportion raw material: nicotine extract 41.5～63.4%, periploca spium extract 27.6～47.5%, honey 1～2%, living garlic 2～5%, dry red pepper 2～5%, Cosan 0～2% vitamin C 0.06～0.15%.Also can add in flolimat, efficient cis fenvalerate, cypermethrin, dichlorvos, the methomyl milk oil one or more in the broad spectrum vegetable insecticide as synergist.A kind of preparation method of broad spectrum vegetable insecticide, the preparation method of nicotine extract is as follows: 500 grams, 60 purpose tobacco powders are added 3500 milliliters in water, the sulfuric acid that adds 7.5 milliliters again, soak to heat after 16 hours and extracted 2 hours, temperature is controlled at 60～70 degree, after the filtration, leaves standstill 10 hours, 85～88% moisture is removed in the filtrate decompression distillation, makes the nicotine extract of 415～634 grams; The preparation method of periploca spium extract is as follows: 3500 milliliters of the ethanol of adding 70% in 500 grams, 60 purpose periploca spium powder, soaked the back refluxing extraction one hour, temperature is controlled at 70～80 degree, after the filtration, decompression distillation removes 85～88% solvent, makes the periploca spium extract of 276～475 grams; The weight ratio of nicotine extract and periploca spium extract is 1: 1 or 2: 1, and wherein extract nicotine accounts for 1.4 ~ 2.8% of extract in the nicotine extract, and extract periploca spium general glycoside accounts for extract 0.8% in the periploca spium extract; In nicotine extract that mixes and periploca spium extract, add honey 10～20 grams again, living garlic 20～50 grams, dry red pepper 20～50 grams, Cosan 0～20 gram, vitamin C 0.6～1.5 gram is promptly.
This agricultural chemicals utilizes cigar mill's production waste-tobacco rods and wild periploca spium skin, extracts its active ingredient through science, is equipped with a kind of broad spectrum type insecticide that wetting agent and synergist are made.This agricultural chemicals has low toxicity, basic noresidue, and is harmless to plant to the person poultry safety, insect do not produced characteristics such as anti-medicine; Various pests had tag and the stomach toxicity function absorption and fumigation action in not having.This pesticide cost is cheap, technology is easy, the nuisanceless generation of preparation process.Raw material periploca spium skin is easy to gather, and helps the utilization of cigarette factory tobacco leaf waste material, can alleviate environmental pollution; Raw material residue after the extraction also can be made fertilizer or be developed as feed.
Research forms broad spectrum vegetable insecticide through long term test, this product is a subacidity dark-brown liquid, preliminary test on vegetables, grain and cotton, woods fruit and flowers all has the insect of food plant bases of leaf such as aphid, two spotted spider mite, leaf roller, cotton sandfly worm and to tag and stomach kills function.Through Institute of Plant Protection, academy of agricultural sciences, Shanxi Province and agriculture chemical examination institution, Hebei two places field control effectiveness test, 400 times of liquid spray, to the preventive effect of aphid 94～97%, remaining drug effect reached more than 12 days, through Shanxi Medical College (existing Shanxi Province medical university) toxicological test, rat is through skin, per os median lethal dose＞10000mg/kg body weight; Family is exempted from skin and mucomembranous irritant test, is slight to skin irritatin intensity, non-stimulated to eye mucosa.Belong to low toxicity according to China's agricultural chemicals acute toxicity classification regulation.
