Description
Technical field
The present invention relates to a kind of insecticide, particularly a kind of agricultural biological insecticide that contains toosendanin.
Background technology
Along with the application of agricultural chemicals more and more widely, human also more and more deep to the understanding of agricultural chemicals.Deep variation has taken place in the notion of the notion of agricultural chemicals, particularly insecticide.Today, we do not pay attention to " killing " but pay attention to " adjusting ".Insecticide desirable in the public mind should be " rationally biological insecticide " (Biorationl insecticides), promptly to pest efficient, to environment, to the insecticide of non-target organism safety.
Following several stages has been passed through in pesticide development: poor efficiency (inorganic pesticide is as arsenic preparation, mercurial); Safe poor efficiency (natural insecticide, the lasting period is short, and is environmentally safe, but some kind is to the high poison of mammal); Efficient high residue (organochlorine insecticide, high residue are difficult for metabolism); Highly-effective low-residue (organic phosphor, carbamate pesticide, easy metabolic degradation in environment, but most of mammals are had high acute toxicity); The high-efficiency low-toxicity low-residual (mostly be class natural products insecticide greatly, as class pyrethrins, class nicotine insecticide etc., and some accidental synthetic insecticides identical with the natural products mechanism of action that filter out); Efficient high selectivity low toxicity and low residue (insect growth regulator, IGR,, also selective) to natural enemy not only to mammalian safe.As seen, along with people to the reinforcement of the attention degree of environmental protection and the development of insect resistance, all demand is brought in constant renewal in insecticide variety always.
Summary of the invention
The object of the present invention is to provide the biological insecticides of a kind of efficient, low toxicity, low-residual.
Insecticide of the present invention is a raw material with the Chinese herbal medicine, extracts its active ingredient and is prepared into insecticide.Specifically, insecticide of the present invention is made by the raw material of following weight portion: Fructus meliae toosendan 50~70, thunder godvine 35~55, Chinese honey locust 30~50, the root of langdu 35~55, tobacco leaf 30~50, the rhizome of Chinese monkshood 25~40, vomiting nut 30~55, kuh-seng 30~55.Be preferably: Fructus meliae toosendan 60, thunder godvine 45, Chinese honey locust 40, the root of langdu 45, tobacco leaf 40, the rhizome of Chinese monkshood 32, vomiting nut 43, kuh-seng 43.
Insecticide of the present invention is prepared from by the extract of above-mentioned raw materials.Wherein preferred toosendanin accounts for 0.8~1.2% of extract dry weight.
The present invention also provides a kind of method for preparing described insecticide, and it comprises step: take by weighing above-mentioned materials of weight proportions, be chopped into meal, extraordinarily go into the organic solvent circulation by 2~4 of raw material gross weight and extract 2~4 times, each 2~3 hours, get extract.The gained extract can be further purified, and perhaps directly uses.The suitable synergist of preferred adding, as add the OP-10 (polyoxyethylene nonylphenol ether) of extract weight 5~15%, and proper amount of surfactant, the BS-12 of liquid weight 5~15% got as adding, stir after adding synergist and surfactant, promptly get insecticide of the present invention.Detecting pH is 4.0~5.2, and Baume degrees is 35~38, and wherein toosendanin content can reach 1.2% (weight).Wherein, the consumption of described organic solvent can be ethanol, dimethylbenzene, perhaps their mixture, and the compound that is preferably ethanol 60~90%, dimethylbenzene 10~40% is as extracting solvent.
Insecticide entry free-running property of the present invention is good, and the conventional spray method is used on crop, and gentle plate-out ability is good, can prevent and treat various pests such as fruit tree, vegetables, flowers and grain crop, have spectrum, be diluted to 1000~1500 times, the control efficiency in 72 hours can reach more than 90%.At the bottom of the insecticide cost of the present invention, effective, the low toxicity noresidue does not have harm to people and animals, has a good application prospect.
