Description
Technical field
The invention belongs to natural insecticide technical field, be specially a kind of containing alkaloidal insecticides and uses thereof.
Background technology
Plant is the natural treasure-house of bioactivator, and from plant, searching has the material of insecticidal activity to research and develop the important channel that biological source insecticide is pesticides discovery.
Along with the enhancing of people's environmental consciousness, the agricultural chemicals of Long-Time Service traditional chemical synthesis receives the concern of the public to problems such as environmental protection, the ecological balance, people and animals and beneficial organism are poisoning.Current many high toxicities, high residue, persistent pesticide are prohibited from using.People also there occurs deep change to the understanding of agricultural chemicals, and the concept of " harmonious environment agricultural chemicals " has obtained general people's accreditation of people.The pest control agent developed since the nineties in 20th century just requires there is better safety to the consumer of user, processed crop and environment, and coordinates to ensure its fundamental position in integrated pest management mutually with biological control thing.Since 2000, the Ministry of Agriculture of China and each place government have put into effect regulations in succession, prohibit the use the malicious high residue chemical pesticide of many height, and from January 1 in 2007, Qi China prohibited 5 kinds of high-toxic organic phosphorus agricultural chemicals such as pin use acephatemet comprehensively.European Union also promulgates regulation, forbids that on July 25th, 2003 uses 320 kinds of agricultural chemicals (or chemicals) afterwards, wherein relates to multiple China still in the kind of producing and in use.Crops using the agricultural chemicals of new type of safe substitute traditional chemical agricultural chemicals has been the task of top priority.From plant, find new active substance, to be synthesized by class or exploitation botanical pesticide that biorational design carries out novel pesticide has become the focus of the research of novel pesticide exploitation.
In the research of Insecticidal Plant Resource, do large quantity research both at home and abroad, and made remarkable progress.The research such as Zeng Dongqiang shows that the situation activity of the methanolic extract of Randia spinosa to diamond-back moth is higher, and the non-selection anti-food rate of 24h reaches 82.49%.Record beautiful equality to report sapindoside and have cytotoxicity to diamond-back moth and fruit bat, activity is not had to corn weevil.The research such as SujathaCH shows that the benzinum of bamboo extracts can prevent and treat five band culexs, Aedes aegypti and anopheles, also certain avoidance effect is had to storage pest, behaviour Hai Qun etc. finds that multiple bamboo class water extract has certain avoidance effect to corundum Sitophilusspp. imago, wherein the highest with the activity of buck bamboo extract.The absolute ethyl alcohol of the research such as Yao Yingjuan discovery crotons, acetone, ethyl acetate, ligroin extraction all have certain repellent action and action of contace poison to corn weevil, lesser grain borer, Cryptolestes pusillus, saw-toothed grain beetle.Xu Hanhong] etc. filter out from 62 kinds of traditional Chinese medicines senecio palmatus contrast housefly have good insecticidal activity.The research such as Feng Jianju shows that the glycyrrhiza inflate bat of Southern Xinjiang and datura have certain drug effect to cotton bollworm.Li Xiumei etc. filter out Lappula echinata, Chinese torreyanut and Gardenia from 18 kinds of Chinese herbal medicines has higher activity to small brown rice planthopper.
At present, domestic and international researcher has carried out a large amount of research about plant insecticide, the aspects such as the extraction and analysis of many several plants source activity composition and biological activity determination.Many plants with insecticidal activity are also had also not obtain research and development.Development of new, safety, efficiently plant insecticide have been trend of the times.
Summary of the invention
For the above-mentioned problems in the prior art, the object of the invention is to design provides a kind of technical scheme containing alkaloidal insecticides and uses thereof, the obtained natural noresidue of insecticide, do not make that insect produces resistance, effective, rapid-action, the lasting period is long, and cheap, easy to use.

Described solvent is one or more mixtures in methyl alcohol, ethanol, water, and described emulsifier is one or more mixtures in 602#, OP-10, JFC;
Described coalescents is one or more mixtures in phenmethylol, butyl glycol ether, Lauryl Alcohol ester.
Described one, containing alkaloidal insecticides, is characterized in that the content of active component is 6-20%, is preferably 10-15%.
Described one, containing alkaloidal insecticides, is characterized in that the content of solvent is 65-80%, preferred 70-75%.
Described one, containing alkaloidal insecticides, is characterized in that the content of emulsifier is 2-10%, preferred 5-8%.
Described one, containing alkaloidal insecticides, is characterized in that the content of coalescents is 3-10%, preferred 4-8%.
Described is a kind of containing the application of alkaloidal insecticides in preparation control Tetranychus cinnabarinus, aphid, diamond-back moth, smaller green leaf hopper, rice fulgorid preparation.
Above-mentioned one is containing alkaloidal insecticides, with the alkaloid of pure natural for active ingredient, add a certain proportion of coalescents in process for preparation, the more permanent adhesion of medicine can be made and cover insect body wall thus reach the effect better killed off the insect pests.Very strong kill activity is all had to insects such as Tetranychus cinnabarinus, aphid, diamond-back moth, smaller green leaf hopper, rice fulgorids, effectively can reduce the economic loss that crops cause because of insect pest, meanwhile, obtained pharmacy effect is desirable, rapid-action, the lasting period is grown, natural noresidue, and Environmental compatibility is good.And with low cost, production and processing method is easy.
The percentage composition related in present specification unless otherwise indicated, other the weight percentage being pure material.
