Description
Technical field
The present invention relates to a kind of aqua type botanical pesticide containing diosgenin and preparation method, belong to technical field of pesticide.
Background technology
Along with the fast development of China's economy, living standard of urban and rural population quality, living standard gradually step up, the food requirement of people from
Having enough originally is sent out to the health eaten, and the quality safety of agricultural product is proposed the highest requirement, fast along with pesticide industry
Speed is grown and development, and the application area of chemical pesticide constantly expands, and amount of application persistently rises, and at present, China's Pesticide use amount is
Occupy the whole world umber one, 2004, the whole nation applications of pesticide amount reach 138.6t, compared with 1991 increase nearly 1 times, be developed country and
2 times of world average level, the long-term unreasonable use of chemical pesticide, severe contamination and destruction agroecological environment, cause meanwhile
Make harmful substance contents excessive problem in agricultural product highlight, cause ecological safety crisis and agricultural product quality and safety crisis further,
The physical and mental health that serious threat is popular, hinders foreign trade and the increasing peasant income of agricultural product, have impact on agricultural products in China in international city
The competitiveness of field, economy and foreign trade to us cause the biggest loss.
Chinese patent literature CN102210327A (application number: 201110153495.8) disclose a kind of new bio wide spectrum kill agent and
Its preparation method, it is to be prepared according to constant weight proportioning mixed fermentation with Fructus Momordicae charantiae fermentation liquid by Bulbus Allii, Bulbus Allii Cepae.The present invention's
Biological broad spectrum bactericide is with natural plants and probiotic bacteria as core, prepared by pure biofermentation, without any chemosynthesis composition, tool
Have efficient, nuisanceless, pollution-free, have no side effect, antibacterial wide spectrum, the advantage of drug effect length, but this patent is by probiotic bacteria nutrition
Competition carries out growth and breeding, thus occupies the mode of vivosphere to stop the growth of phytopathogen, can be rapid at plant surface
Forming a floor height password protection cuticula, its antibacterial substance contained, while suppression pathogenic bacteria spore germination and mycelial growth growth, also presses down
Make hypha of edible fungus to sprout and growth, cause the edible fungi significantly underproduction.

Character: crystalline solid.Decomposition point～277 DEG C.Optical rotation-115 (c=0.373, ethanol).Water insoluble, petroleum ether, benzene,
Dissolve in methanol, ethanol, acetic acid, be slightly soluble in acetone, amylalcohol.
Being naturally occurring in the rhizome of Dioscoreaceae plant Rhizoma Dioscoreae Nipponicae, the rhizome of Rhizoma Dioscoreae Zingiberensis, in the plant such as rhizome of Foochow Rhizoma Dioscoreae.Rhizoma Dioscoreae
Saponin is widely present in the plants such as Shu Cai section, Liliaceae, pulse family, and wherein rich content in Dioscoreaceae plant, such as Dioscorea nipponica potato
Sanction, Rhizoma Dioscoreae, matter leaf potato sanction etc..The effects such as it eliminates the phlegm, desensitize, antiinflammatory, blood fat reducing, antitumor.Kill insecticide and anti-tinea barbae hair
The effect of the funguses such as bacterium.Can be as synthesizing steroid hormone and the raw material of contraceptive.Development diosgenin produces and processing, prospect
Wide.
Green a kind of green, nuisanceless, low-residual non-chemical pesticide becomes a difficult problem to be solved at present.
Summary of the invention
For the deficiencies in the prior art, the present invention provides that a kind of bactericidal effect is good, noresidue, the multiple fungus damage of preventing and treating containing Rhizoma Dioscoreae
The aqua type botanical pesticide of Saponin, this botanical pesticide does not contains organic solvent, to human non-toxic, nonflammable, stores and transports safety,
It is that country advocates the environmentally friendly novel form developed.
