Abstract
The invention relates to an emulsifiable concentrate pesticide containing 2.4% of oxymatrine, which belongs to the field of botanical pesticides. The pesticide mainly comprises 20% of sophora flavescens, 20% of castanopsis sclerophylla, 10% of tobacco, 5% of derris, 5% of tripterygium wilfordii, 20% of pterocarya stenoptera, 6% of hops, 4% of humulus scandens, and 10% of zanthoxylum schinifollum. The pesticide is able to kill the pests mainly in a contact killing manner and has characteristics of high decomposition speed, no residual, no pollution to the family environment and the like. The pesticide has obvious preventing and killing effect on multi-species of pests, such as Lepidoptera, Hemiptera, Coleoptera, Homoptera, Diptera and the like, in vegetables, fruit trees, flowers, forest trees, and field crops.
Description
Technical field
The present invention relates to a kind of oxymatrine cream pesticide, belong to plant insecticide field.
Background technology
China is a typical large agricultural country, always rural economy, rural development and rural demography are one of the important policies of China, for a long time, because using chemical pesticide in a large number, cause vast rural area farm produce production base to produce the serious three disasters, damage by disease and insect pesticide resistance constantly increases, and has buried hidden danger to the safety of agricultural product, in addition, the pollution of residue of pesticide to 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.Use green, safety, non-harmful plant insecticide, important developing direction must be become, have wide market development prospect, pollute for environmental protect, the safety increasing agricultural product all has epoch-making meaning, (CN101720791A) the matrine insecticide aqua in, it is poor that existence exhibition is puted forth effort, the problem that the duration is short, needs to use in a large number, cost is high, causes unnecessary loss.
Summary of the invention
The present invention is to overcome weak point of the prior art, there is provided a kind of matrine extracted from plant kuh-seng to be primary raw material, add particular emulsifier, make to person poultry harmless, low toxicity super-high-efficient, exhibition is puted forth effort strong, matrine content up to 2.4% cream pesticide.
The present invention is achieved through the following technical solutions: a kind of oxymatrine cream pesticide, be by Chinese medicine extract and auxiliary agent formulated, wherein Chinese medicine extract is made up of kuh-seng, bitter strain, tobacco, trifoliate jewelvine, thunder godvine etc., its compatibility is: kuh-seng 20%, bitter strain 20%, tobacco 10%, trifoliate jewelvine 5%, thunder godvine 5%, maple willow 20%, hop 6%, rule grass 4%, mountain flower green pepper 10%, emulsifier in auxiliary agent, use No. 324, agriculture breast and agriculture breast No. 500 compound proportions to be 3:2, ratio is only 3%.
A kind of oxymatrine cream pesticide has following advantage:
1. there is efficient, broad spectrum activity
To Lepidoptera, the Semiptera of vegetables, fruit tree, flowers, forest, field crop, stick up the various pests such as wing order, Homoptera, diptera and have and significantly kill and preventive effect.
2. safety non-toxic is pollution-free
The general toxicity ratio of chemical pesticide is larger, while kill pests, the life security of people and animals is also worked the mischief, and 2.4% oxymatrine missible oil, that pure natural plant is made, effectively avoid the threat of chemical pesticide composition to people and animals, belong to a kind of safe agricultural chemicals, through field trial repeatedly, it has the effect of excellent pest control, and does not find people and animals' intoxicating phenomenon, is the desirable regeneration product of existing agricultural chemicals, there is not residue problem through overtesting, any danger side of body is not formed to ecotopes such as people and animals yet.Production overall process adopts and recycles, and effectively reduces three industrial wastes.
3. raw material sources are extensive, cheap
These raw materials such as kuh-seng, tobacco, trifoliate jewelvine, thunder godvine, Dalmatian chrysanthemum are all easy to get, particularly radix sophorae in China northeast, there is growth the mountain area of North China most area and hilly country, spring, Qiu Erji can excavate.
Matrine (
sophoraflavesensait), belong to leguminous plant.The matrine with insecticidal action extracted from radix sophorae and the structural formula of oxymatrine as follows:
Chemical formula is: C
15h
24n
2o, C
15h
24n
2o
2, relative molecular mass is respectively: 248.36, and 264.36.
A kind of processing method of oxymatrine cream pesticide is as follows:
Get kuh-seng, tobacco, China tree, Dalmatian chrysanthemum, thunder godvine, pepper, respectively pulverization process, for subsequent use after crossing 40-80 mesh sieve; Get above-mentioned various raw material by charge ratio to be respectively charged in stainless steel batch extractor, add crude drug 6-8 times water gaging, soak 4-8 hour at normal temperatures, less than 95 DEG C, secondary is extracted in boiling, carries 4-8 hour at every turn, and secondary raffinate merges, filtration, and it is for subsequent use to collect gained filtrate; Each for gained filtrate is inputted in Three-effect concentration device respectively, is decompressed to 0.5-0.1MPa, at 70-95 DEG C of temperature, be concentrated to 1ml be equivalent to crude drug 3-5g, be i.e. 22-28Be, measure content and collect concentrate, obtain extract; Each for gained concentrate is placed in reactor, 70% ethanolic solution is added in 3-4:1 ratio, stir 20-60 minute, put into settling tank precipitation 10-48 hour, elimination insoluble matter, detect matrine to standard content, by in gained filtrate input destilling tower, be heated to 85-95 DEG C of distillation, collect mother liquor to be input to again in reactor, add by required charge ratio ethanol, preservative, the bleeding agent that concentration is 75-90% successively, and emulsifier, by above-mentioned various auxiliary agent mixing 1.5-3h, obtain the oxymatrine cream pesticide that the content shown in invention is 2.4%.
Embodiment one:
Manufacture oxymatrine cream pesticide shown in invention, by kuh-seng, bitter strain, tobacco, trifoliate jewelvine, thunder godvine, maple willow, hop, rule grass, mountain flower green pepper, through cleaning, pulverize, extraction, concentrated, alcohol precipitation, return and heat up in a steamer, be mixed, the compatibility of its kuh-seng, bitter kerria, tobacco, trifoliate jewelvine, thunder godvine, maple willow, hop, rule grass, mountain flower green pepper is: kuh-seng 52g, bitter strain 52g, tobacco 26g, trifoliate jewelvine 13g, thunder godvine 13g, maple willow 52g, hop 15g, restrain careless 11g, mountain flower green pepper 26g.
Its process is: 1. get kuh-seng, bitter strain, tobacco, trifoliate jewelvine, thunder godvine, maple willow, hop, rule grass, mountain flower green pepper by above-mentioned compatibility respectively, and wash respectively, after drying and crushing, sieve by 20-80 mesh sieve.
2. respectively with the imitative extraction of atmosphere, reduce with water, carry out again concentrating, liquor-saturated heavy (adopt second liquor-saturated), backflow, finally extract is mixed, add emulsifier again, the extract finally obtained comprises matrine 2.4%, nicotine 0.3%, bitter kerria's alkali 0.6%, wilfordine 0.4%, rotenone 0.1%.
The various pests such as Lepidoptera, Semiptera, Homoptera, diptera of this insecticide to vegetables, fruit tree, flowers, forest, field crop all has obvious control efficiency, Nantural non-toxic, to person poultry safety, harmless to environment.
