Description
Technical field
The present invention relates to a kind of insecticide, particularly a kind of plant insecticide that from various plants, extracts effective ingredient and prepare.
Background technology
Citrus is one of topmost fruit of southern china, and edibility is high, and economic benefit is considerable, mainly cultivates each province on the south the Changjiang river.In recent years, because weather changes warm, citrus thing marquis's phase was long, so mandarin orange pest is of a great variety, harm is on the rise.The bigger insect that causes damage has two spotted spider mite, scale insect, citrus leaf-miner etc.
Mostly the insecticide of prior art is chemical pesticide, and its drug effect is low, and the residual hazard phase is long, has a strong impact on crop growth environment and human and livestock health.Agricultural chemicals is one type of particular chemical article, and it can prevent and treat the agricultural damage by disease and insect, also can produce harm to people and animals.Therefore, the use of agricultural chemicals is brought benefit to the mankind on the one hand; The environment of also depending on for existence to the mankind on the other hand brings harm; Owing to use chemical pesticide in a large number, air, water source, soil and food have received pollution, and poisonous substance causes poisoning etc. in the middle of being accumulated in domestic animal and human body.And, use some chemical pesticide that insect is developed immunity to drugs for a long time, existing 417 kinds at present of drug-fast insects are arranged.According to bibliographical information, the agricultural chemicals availability is generally 10%, and about 90% residual causes the pollution to environment in environment.A large amount of agricultural chemicals evaporate in the air, flow in the water body, sedimentation accumulates in the soil, pollute farming animals fishing fruit product, and transfer in the human body through the enrichment of food chain, and human body is produced harm.The agricultural chemicals of efficient severe toxicity, toxicity is big, and in environment residual time long, when people and animals have eaten the food that contains remains of pesticide, will cause the poisoning of accumulation property.The accumulation that this type harm often will be passed through the long period just demonstrates symptom, and it is again the enrichment through food chain, just gets into human body at last; Be difficult in time finding, therefore, generally do not paid attention to by people; And this type pollution range is wide, and the number of harm is many, in many cases; Be that the mankind control oneself in murder by poisoning oneself, thus, this type harm is dangerous more.
In a single day agricultural chemicals gets into environment, and its toxicity, high residue characteristic just can generating effects, cause the pollution of serious atmosphere, water body and soil, thereby bring harm to human health.When the poisonous applications of pesticide are on crops, fruit and vegetables, remain in the agricultural chemicals on the crop surface, since fat-soluble strong, be easy to infiltrate the wax coat of crop epidermis, so that be difficult to wash fully.If make the feed of livestock with these contaminated grains, vegetables, then residual agricultural chemicals will be transferred in meat, breast type and the egg product and cause pollution, finally gets into human body with food.Agricultural chemicals also can enter rivers with the irrigation water in farmland; So that agricultural chemicals retains in the strong water plants of drug resistance; Accumulate in birds, fish and aquatic bird body through complicated biochemical cycles subsequently,, finally get into human body along with the trophic level enrichment and the transfer gradually of food chain; Cause chronic poisoning, even cause cancer.Agricultural chemicals mainly is to get into human body through food chain, in fat and liver, accumulates, thereby influences normal physiological activity.
Therefore, be necessary to propose a kind of novel vegetable insecticide, crops are not had poisoning, noresidue, free from environmental pollution and agricultural product, to people and animals also safety, and the insecticide of especially suitable Citrus insect.
Summary of the invention
In view of this; Plant insecticide of the present invention, its selected plant all is that natural world is ubiquitous, natural microorganism has formed degradation mechanism to it already; Crops there are not poisoning, noresidue, free from environmental pollution and agricultural product; Strong to the insect lethal effect, safe, preventive effect is good and with low cost.Especially be suitable for the control of mandarin orange pest two spotted spider mite, scale insect, citrus leaf-miner etc.
Plant insecticide of the present invention; From kuh-seng, tobacco, monkshood, radix aconiti agrestis, Herba Achilleae, Jehol Ligusticum Rhizome, vomiting nut, the fruit of Rangoon creeper, crotons, extract effective ingredient; Said effective ingredient is: matrine 55-70%, nicoteine 0.5-5%, and the percentage that the gross weight of aconitine, Rhizoma Ligustici oil, strychnia, fruit of Rangoon creeper's acid potassium, crotin accounts for insecticide is 25-44%;
Further, said effective ingredient is: matrine 60%, nicoteine 1%, and the percentage that the gross weight of aconitine, Rhizoma Ligustici oil, strychnia, fruit of Rangoon creeper's acid potassium, crotin accounts for insecticide is 39%;
Further, the mixed proportion between said aconitine, Rhizoma Ligustici oil, strychnia, fruit of Rangoon creeper's acid potassium, the croton oil is: 3: 1: 2: 1: 1.
Matrine is an agricultural chemical of natural plant, and in a single day insect touches this medicine, promptly benumbs nerve center, makes the polypide protein coagulating then, increases dead polypide pore, and insect is choked to death, and to the people, animal low toxicity, is broad spectrum pesticide, has and tags and stomach poison function.Insects such as the cabbage caterpillar on the various crops, aphid, two spotted spider mite there is tangible control efficiency.
Nicoteine is the primary raw material of low toxicity strengthening plant insecticide, nicotine commercial as parasitic expellent in insecticide and the animal doctor's medicament.Nicotine severe toxicity, lethal dose is 40mg, can prevent and treat the production damage by disease and insect on agricultural, the gardening such as the withered worry of aphid, snout moth, rice fulgorid, late rice, cutworm, two spotted spider mite of multiple kinds of crops such as wheat, cotton, vegetables, tobacco leaf, fruit, paddy.
Aconitine can make people's heart rate slow down, pulse soft and a little less than, blood pressure edges down, and can suppress respiratory center, makes to breathe to slow down, and to sensory nerve ending excitement earlier, itch, the burn feeling of local skin and mucosa, continues to benumb unconsciousness.
Crotin can influence elongation factor 1 and 2 and ribosomal interaction, suppresses phatidylcholine esterase active effect, thereby causes insect death.
Strychnia can make central nervous system excited.At first strengthen the spinal reflex excitability, make it exagger.The respiratory center and the vasomotor center of next excited oblongata, and the susceptibility of raising cerebral cortex sensorium (look, listen, smell).
Rhizoma Ligustici oil, acute toxicity experience was tried to achieve mouse stomach Jehol Ligusticum Rhizome neutral oil 72 hours with karber's method, and median lethal dose is 70.17 ± 4.95g/kg (pressing crude drug calculates).
Fruit of Rangoon creeper's acid potassium, but expelling parasite has renal toxicity, can cause kidney damage.
Extract of the present invention extracts through methods such as alcohol-pickled, Suo Shi extractions, plants the ripening fruits that subclass is preferably gathered then, skin, root, directly, leaf is the new dry product of gathering then.
Its plant extracts can replace with commercially available functional component, exempts and extracts procedure, and its component content is also purer.
Beneficial effect of the present invention: plant insecticide of the present invention, toxicity is big, belongs to desinsection, kills mite dual-purpose agricultural chemicals, the function of tagging, stomach toxicity function, food refusal function is arranged, suppress the insect function of growing.Aconitine has powerful anesthetic effect, suppresses the nervous system of insect, interrupts the neurotransmission of insect; With the fruit of Rangoon creeper's acid potassium acting in conjunction that promotes that neuronal cell is downright bad; Have the paralysis of enhancing polypide, destroy the effect of insect nervous function rapidly, suppress the respiration of insect; Strychnia stimulates the skin of insect, makes the skin and mucosa sensory nerve present excitatory state, produces itch and burning heat sensation, continues with the anesthesia insect, and insect is lost consciousness; The intense stimulus performance damage polypide epidermis of croton oil destroys the chitin of polypide; Crotin can suppress the polypide acetylcholine esterase active, causes insect death; Nicotine is blocked the conduction of insect central nervous system through Selective Control insect nervous system nicotinic acetylcholine esterase acceptor, thereby causes insect paralysis and then dead to occur; And that Rhizoma Ligustici oil has is antibacterial, the effect of expelling parasite.Plant insecticide of the present invention, each effective ingredient complements each other, synergy, have interior absorption strong, quick-acting good, active high, the lasting period is grown, can kill ovum can kill larva again, adult can be used for the control of insect of aspects such as vegetables, fruit tree, crops.Because of its selected plant all is that natural world is ubiquitous; Natural microorganism has formed degradation mechanism to it already, and crops are not had key, noresidue, free from environmental pollution and agricultural product, does not kill natural enemy; Mammal there are not teratogenesis, carcinogenic, mutagenic harm; Strong to the insect lethal effect, highly effective and safe, preventive effect is good and with low cost.Especially be suitable for the control of mandarin orange pest.
