Abstract
The present invention relates to pesticide and its preparation process fields, specifically, are related to a kind of compound botanical fungicide and the preparation method and application thereof.In terms of mass fraction, mainly it is made of following material component：30~40 parts of plant extracts essential oil, 20~30 parts of organic solvent, 7~11 parts of surfactant, 4~8 parts of bleeding agent, 20~30 parts of water；The plant extracts essential oil is obtained by cloves and Chinese cassia tree by extraction by steam distillation.The fungicide has strong inhibiting effect to more target plant disease fungus simultaneously.Meanwhile the group credit union of different type active constituent delays the generation of germ drug resistance.
Description
Technical field
The present invention relates to pesticide and its preparation process fields, specifically, be related to a kind of compound botanical fungicide and its
Preparation method and application.
Background technology
Applied chemistry synthetic pesticide has the characteristics that preventive effect is good, quick, be currently the prevention and control of plant diseases, pest control important means it
One.But it is long-term a large amount of unreasonable using chemical synthetic pesticide, especially high poison, persistent pesticide, pesticide residue can be caused super
Mark, environment and agricultural product are contaminated, endanger human and livestock health, pest and disease damage develops immunity to drugs, preventive effect reduces, or even largely kills day
Enemy, causes pest and disease damage rampant once again, destroys life and knows balance.Here it is " 3R " problems of so-called chemical pesticide.
Botanical pesticide has the characteristics that low toxicity, noresidue, safer to natural enemy；Meanwhile botanical pesticide contain it is more
Kind chemical composition is not likely to produce drug resistance, thus botanical pesticide is to solve the problems, such as " 3R " comparatively ideal a kind of public nuisance-free agricultural chemicals,
It is to solve international agriculture trade Green barrier and one of the important means of production green and organic food, in recent years, plant
The research and development and application of source pesticide gradually obtain the great attention of the Ministry of Agriculture, the Department of Science and Technology, Ministry of Industry and Information, the Committee of Development and Reform, and obtain fast
The development of speed.
There are mainly two types of modes for the exploitation of botanical pesticide at present, first, pesticide activity component is found from plant, as
The lead compound of the new chemical pesticide of synthesizing efficient low toxicity；Second is that botanical pesticide is made in directly appliable plant resource.It is external more
Using first way.The country because plant resources are abundant, mostly in the second based on.China has Activities of Some Plants pesticide at present
Patent or product come out, but wherein most is plant insecticide, and it is then very few to be related to botanical fungicide.
In view of this, special propose the present invention.
Invention content
It is that compound botanical prepared by raw material kills that the purpose of the present invention is to provide a kind of using medicinal plant cloves and Chinese cassia tree
Microbial inoculum.
In order to realize that the above-mentioned purpose of the present invention, spy use following technical scheme：
The present invention relates to a kind of compound botanical fungicides, in terms of mass fraction, are mainly made of following material component：
30~40 parts of plant extracts essential oil, 20~30 parts of organic solvent, 7~11 parts of surfactant, bleeding agent 4~8
Part, 20~30 parts of water；
The plant extracts essential oil is obtained by cloves and Chinese cassia tree by extraction by steam distillation.
According to an aspect of the present invention, the invention further relates to the preparation method of compound botanical fungicide as described above,
Including：
Each material component is mixed, shear agitation is uniform.
According to an aspect of the present invention, it is vertical in prevention eggplant that the invention further relates to compound botanical fungicides as described above
Application in blight, powdery mildew of cucumber, graw mold of tomato and notoginseng root rot.
By adopting the above-described technical solution, compared with prior art, it is made of raw material that the present invention, which selects cloves, Chinese cassia tree,
Fungicide has very strong inhibiting effect to a variety of target pathogens.Even if the downy mildew being difficult to control to general pesticide, grape spore
Mould, sickle-like bacteria also has preferable fungistatic effect, this, which is other plant pesticide, to compare.
The plant pesticide prepared as stated above can be used for the crop disease caused by various plants pathogen.It is main to use
Withered bacterium, sickle-like bacteria, wheel branch are stood by downy mildew, botrytis sp, Phoma sp, epidemic disease bacterium, anthrax bacteria, Alternaria, eggplant in prevention
Plurality of plant diseases caused by bacterium, pestalotia bacteria, smut can be used for preventing wheat, corn, rice, potato, sweet
The field crops such as sugarcane, beet, peanut, cotton；The vegetable crops such as Chinese cabbage, tomato, cucumber, pimento, capsicum, pea, hyacinth bean；Cherry
The industrial crops such as peach, peach, pears, apple.
Preparation cloves Chinese cassia tree mixture made of the present invention, the primary raw material used are Chinese medicine cloves and Chinese cassia tree (cassia bark),
Our common flavorants, the main active of preparation is cinnamic acid, eugenol, the activity of two kinds of inconsiderate types at
Split-phase mutually cooperates with, action compensating, is used respectively than single, and synergy is notable, while greatly reducing controlling disease cost, increases
Prevention spectrum, while having strong inhibiting effect to more target plant disease fungus.Meanwhile the group credit union of different type active constituent prolongs
The generation of slow germ drug resistance.
