The invention relates to a insecticide prepared from plants, especially to a compound botanical insecticide containing pokeberry. The pokeberry is a poisonous plant containing phytolaccatoxin and other substance which can kill plant insect, the pokeberry source in our country is abundant and is a good plant species for preparing compound insecticide. The formulate composition of the raw material( percent by weight) is: pokeberry, 10-50%; margosa, 10-50%; kuh-seng, 10-35%, stemonine, 0-35%; radix euphorbiae ebracteolatae, 0-20%; tobacco, 3-5%. The killing effect of insecticide to most plant insects is good, and the insecticide is harmless to natural enemy which is good for ecological balance, the combination property of killing insects and protecting environment is sound. The insecticide is a product coincident with the requirement of environmental protection with good performance.
Description
One, affiliated technical field: the present invention relates to plant insecticide, especially a kind of compound plant insecticide that contains Phytolacca acinosa.
Two, background technology: along with the development and the continuous progress in science and technology of society, people's environmental consciousness is being strengthened gradually, press for development low toxicity, efficient, it is short to have broad spectrum disinfestation performance, toxic residue time, and ecotope and human health is not constituted the novel non-pollution agricultural chemicals of harm.Contemporary society not only pursues and all kills nuisance fast the requirement of agricultural chemicals, and the factor that influences biological physiology, the ecological balance also becomes the problem that the desirable agricultural chemicals of invention should be paid attention to.
Botanical pesticide is compared with chemical pesticide and is had the following advantages: biologically active diversity, botanical pesticide not only have insecticidal function, also have concurrently sterilization and stimulating plant the growth effect; Its mode of action have concurrently tag, stomach toxicity, fumigate, avoid keep away, food refusal and growing suppresses etc.; The active chemical that contains in the botanical pesticide be the structure that has of natural world itself, occurring in nature can biological decomposition, photolysis or oxidation by air, noresidue can enrichment method, contaminated environment; In the process of kill pests, safer to the natural enemy of higher mammal and insect; Botanical pesticide often contains several insecticidal active ingredients, its mechanism of action is different with general chemical pesticide, and insect is difficult for producing adaptability; Botanical pesticide is the environment friendly agricultural for chemical pesticide.
Contain polytype insect killing substance in the plant, mainly contain alkaloids, terpene, aldehydes matter, tannin, essential oil class, photoactivation toxin etc.Early stage botanical pesticide once adopted single plant, but found afterwards that select for use the multiple plant that contains different active ingredients to be re-dubbed compound pesticide, the desinsection kind increased, and insecticidal effect obviously improves.So the disclosed patent publication No. of China national Department of Intellectual Property is the insecticide of CN1507781A, adopt sandliving sophora seed, China tree, tobacco, the tuber of stemona, Dalmatian chrysanthemum, Rhododendron molle, thunder godvine etc. to form compound; Patent publication No. is that the insecticide of CN1502243A adopts Celastrus angulatus, China tree, melia toosendan, calamus, the root of langdu, the rhizome of Chinese monkshood and Chinese wild pepper to form compound; Patent publication No. is that the insecticide of CN1217883A adopts compound that China tree, Sophora alopecuroide, Dalmatian chrysanthemum, the tuber of stemona, the root of langdu, tobacco leaf form or the like, has all obtained insecticidal effect preferably.Phytolacca acinosa is the poisonous plant that contains materials such as phytolaccatoxin, has the effect of killing plant insect, and abounds with in China, is preparation compound pesticide plant resource preferably.So far, do not see the report and the application that are used for insecticide about Phytolacca acinosa, the agricultural chemicals of Phytolacca acinosa does not obtain utilizing with being worth as yet.
Three, summary of the invention:
The objective of the invention is, utilize the plant pokeweed abound with in China, with the composite making good disinsection effect in various plants source, harmless and be of value to environmental protection, the compound plant insecticide of high comprehensive performance.
Compound plant raw insecticide material formula of the present invention consists of (percentage by weight):
Phytolacca acinosa 10-50%, China tree 10-50%, kuh-seng 10-35%, tuber of stemona 0-35%, root of langdu 0-20%, tobacco 3-5%.
The selection that is used for this prescription plant material required be: trade route, the root of langdu with fresh collection, dry without the root piece of concocting, China tree is got azedarach, kuh-seng, the tuber of stemona refer to traditional Chinese medicine, tobacco is tobacco leaf or the nicotine that extracts from the equivalent tobacco leaf.All plant material all carries out preliminary treatment, and temperature is dried, pulverized, sieves in the warp respectively.
Adopt the active ingredient in the solvent extraction method extraction compound plant.The configuration proportion of extract and consumption are: adding concentration by the 100g plant batch feeder is methyl alcohol or the ethanol extraction solution 300-800ml of 30%-95%, or to add concentration be the acetone extract solution 300-500ml of 30-50%, or chloroform extraction liquid 300-500ml.
By the predetermined ratio batching, extraction divides to add in the compound plant raw material for preparing for three times with solution fully soaks into, and carries out three extractions respectively through pretreated raw material, and the process conditions of extraction are:
30 ℃ of extraction temperature are to boiling point, and extraction total time is 3-10 hour.Control temperature with water-bath in the extraction process, the temperature-controlled precision of water-bath is ± 1 ℃.After each extraction finishes, adopt suction filtration and mechanical expression method separating and extracting liquid, and the elimination insoluble matter.
Merge the extract of three extractions, be distilled to predetermined, and carry out the extract solubility property and measure,, adjust the HLB value of the emulsifier that is added according to measurement result.Add emulsifier, emulsification 2-5 hour, extract is prepared as insecticide emulsifiable concentrate, respectively 10 ℃, 30 ℃, the 50 ℃ dispersibility checks of carrying out missible oil.Prepared compound pesticide missible oil all has good dispersibility under three temperature.
Beneficial effect: the used plant of the present invention is all abounded with in China, and the source is abundant, is easy to obtain.Prepared insecticide is used to kill plant insect, and insecticidal effect is good, and harmless to natural enemy, helps the ecological balance, and the high comprehensive performance of go out evil, environmental protection is a kind of good vegetable insecticide that meets environment protection requirement.
