Description
Technical field
The present invention relates to agricultural insecticidal field, especially a kind of matrine aqueous solution of insecticide and preparation method thereof.
Background technology
China is the country that world population is maximum, is again a large agricultural country.Developing rural economy, exploitation agricultural and related industry are one of important policies of China.For a long time, China's vast village's farm produce production base, because a large amount of chemical pesticide that uses causes the serious three disasters, the pesticide resistance that damage by disease and insect produces, has become the latent disease of agricultural crops, plant.The pollution of residue of pesticide to food chain and environment is outstanding day by day.Three disasters problem not only constrains the development of agricultural, and seriously jeopardize human life with healthy, the harm that it causes is immeasurable simultaneously.Long-Time Service chemicals agricultural chemicals, to the harm of environment and related industry, displays in people's each side of living.In order to restrict these harm, five kinds of chemical pesticides were destroyed in 2007 by the Ministry of Agriculture.The contour malicious organophosphorous pesticide of acephatemet, parathion-methyl, parathion, nuvacron and thiamines, will relate to 288 pesticidal preparations and stop on crops and use.Therefore, green plant pesticide, bactericide will become main developing direction, have wide market development prospect.
Summary of the invention
Goal of the invention of the present invention is: for above-mentioned Problems existing, and provide a kind of matrine aqueous solution of insecticide and preparation method thereof to have toxicity little, the toxic residue time is short, has significant anti-personnel feature to Homoptera worm and Lepidoptera worm.
The technical solution used in the present invention is as follows: a kind of matrine aqueous solution of insecticide, comprises the Chinese medicine extract 20-25 part containing matrine by weight, tuberostemonine 5-10 part, capsaicine 3-5 part, Tea Saponin 8-10 and deionized water 80-120 part composition; The described Chinese medicine extract containing matrine is by weight with kuh-seng 25-35 part, tarragon 7-12 part, is the extract of raw material after the mixing of azedarach 2-5 part.
Preferably, comprise the Chinese medicine extract 20-23 part containing matrine by weight, tuberostemonine 8-10 part, capsaicine 4-5 part, Tea Saponin 8-9 and deionized water 100-120 part composition.
Preferably, the described Chinese medicine extract containing matrine is by weight with kuh-seng 30-35 part, tarragon 7-10 part, is the extract of raw material after the mixing of azedarach 4-5 part.
Preferably, by weight also containing sodium alginate 3-5 part and ethanol 10-13 part.
The preparation method of matrine aqueous solution of insecticide, comprises the following steps:
A, take kuh-seng 25-35 part by weight, tarragon 7-12 part, azedarach 2-5 part is placed in water soaks after 2.5 hours, be warmed to 45 DEG C to keep 20 minutes, then the unit of activity adding 8 parts is that the cellulase of 100U carries out enzymolysis, enzyme digestion reaction temperature is 45 DEG C, and the enzyme digestion reaction time is 1-3 hour, filters and obtains medium-height grass extract;
B, get above-mentioned Chinese medicine extract 20-25 part containing matrine by weight and drop in tank, start to stir 25 DEG C time, and add tuberostemonine 5-10 part according to this, capsaicine 3-5 part, Tea Saponin 8-10 part, deionized water 80-120 part, sodium alginate 3-5 part, ethanol 10-13 part, is slowly warming up to 45 DEG C and continues stirring 15 minutes, then be cooled to 20 DEG C, then continue stirring and within 1 hour, obtain matrine aqueous solution of insecticide of the present invention.
Tarragon is inhibited to polypide intestines and stomach.
The expelling parasite of azedarach melia is effective, but has certain toxicity.
Tuberostemonine has killing action to mouse pinworm, head louse, body louse, crab louse, animal lice, bedbug, fly maggot etc.; Relexation is had to the isolated guinea pig bronchial muscular spasm caused by histamine.
Capsaicine is obvious to the action of contace poison of insect, namely shows paralysis (inertia, do not take food), paralyses, the phenomenon of finally death after insect contact with capsaicine.
Tea Saponin has certain stomach toxicity and stronger deterrent effect to cabbage caterpillar, and concentration is higher, avoid keep away stronger, to control cabbage caterpillar harm cabbage have certain effect.Landscape flower is used as insecticide control soil insect, as the insect such as cutworm, nematode.Also all there is good toxic effect to the Pomacea canaliculata of hazard rice and snail, oncomelania etc.
The effect of sodium alginate main stabilization agent.
Ethanol is when intake increases, and its central nervous system inhibitory action strengthens, and first acts on cerebral cortex, then affects subcortical center, can cause oblongata vasomotor center and respiratory center paralysis.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: by extracting the virulent composition of insect tool at kuh-seng, tarragon, azedarach etc., suppress the intestines and stomach of insect, making insect weak, eliminating destructive insects; Add tuberostemonine again, capsaicine, Tea Saponin make its to insect tag and stomach kills more obvious, increase the weight of the toxicity to insect; Add ethanol anesthesia insect nervous centralis, finally add sodium alginate and stablize the combination property of medicine of the present invention.The present invention is extracting directly from plant, little to the murder by poisoning of human body, remarkable to pest control, and shorter in the time that crops body stops, so can effective pre-insect-pest, reduces the poisoning possibility of human body simultaneously.
