Description
Technical field
The present invention relates to plant disease Control Technology fields, and in particular, to a kind of sterilization of prevention and control bacterial soft rot of potato
Composition.
Background technique
Potato nutritional is abundant, and yield is high, is not only important industrial crops and vegetable variety or China high and cold mountain area
The staple food grain of the people.But potato disease is also very serious simultaneously, and processing is bad just to will affect yield, but also can seriously affect it
Quality and nutritive value.Bacterial soft rot of potato is one kind of most serious in potato bacterial disease, it not only occurs in seedling stage,
Store sth. in a cellar phase more easily generation.In China potato producing region, cause the mainly carrot soft rot Erwinia of bacterial soft rot of potato recklessly
The soft rotten subspecies (Erwiniacarotovorasubsp.carotovora, E.c.c) of radish, plant are grown by after pathogen infection
Phase, old leaf piece near the ground was first fallen ill, and sick portion is in irregular crineous scab, was rotted when humidity is big；Potato wedge softening, potato meat is in greyish white
Color rots, foul smelling taste.It is usually relatively difficult for the prevention and treatment of bacterial disease, it can be used for the efficient low of chemical prevention
Poisoning bacterial pesticide is less, and preventive effect is often not satisfactory, but also will cause the pollution of environment and agricultural product.
Black false hellebore is Liliaceae Veratrum, is herbaceos perennial, and jervine is present in Liliaceae Veratrum and spray
It sneezes in careless platymiscium, raw material is the seed of sabadilla and the rhizome of white black false hellebore, RADIX ET RHIZOMA VERATRI NIGRI.Plant material is extracted or mentioned through ethyl alcohol
It takes obtained.Correlative study shows jervine to plant disease such as brown rot, gray mold, soft rot, scab, bacillary perforation
Disease, downy mildew, phytophthora root rot, powdery mildew, late blight, dry rot have good inhibiting effect.
Zhongshengmycin belongs to N- glycoside antibiotic, and antimicrobial spectrum is very wide, can resist Gram-positive, negative bacteria well,
Multiple diseases caused by mycobacteria, saccharomycete and filamentous fungi.To Bacteria erwinia, angular leaf spot fungus, leaf spot bacteria, rice blast
Bacterium, Target spot pathogen, gibberellic hypha etc. all have apparent antibacterial activity.Its mechanism of action are as follows: by inhibiting microorganism albumen
Matter synthesizes and keeps microorganism dead；Made by making der Pilz deformation of filament, inhibiting spore germination or directly killing the modes such as spore
For filamentous fungi；The generation of the precursor substance of protective plant protecting agent and lignin in plant can be stimulated, to improve the disease-resistant of plant
Ability increases income conducive to crop yield.
Graphene oxide (GO) is a kind of two-dimensional surface material of monoatomic layer, has very big specific surface area.Due to GO
There are many oxygen-containing groups on surface, so GO also has good hydrophily.The sterilization mechanism of GO material is substantially divided at present
For following 3 kinds of mainstream opinions: the edge of nano material damaging cells film as blade leads to intracellular DNA, RNA and thin
Born of the same parents' device etc. leaks into extracellularly, leads to cell death；The oxidative pressure that material generates can be with the enzyme and albumen of oxidizing bacteria cell
DNA can be oxidizing to and untwist and be broken, while can also aoxidize mitochondria by matter, and energy supply is made to go wrong；Nano flake packet
Cell membrane is wrapped up in and wound, bacterium is come out with ambient environment, some important channels blocked on cell membrane allow cell cannot
Energy exchange is generated with surrounding.
On the one hand, jervine and Zhongshengmycin all have higher bactericidal activity, if but long-term exclusive use, it is easy to make
Plant germ develops drug resistance, and then generates the problems such as dosage increases, preventive effect reduces, the lasting period shortens.Meanwhile pesticide is anti-
Multiple use will also result in the degradation rate decline of pesticide in the soil, be unfavorable for very much environment sustainable development.On the other hand, stone is aoxidized
Although black alkene bactericidal effect is fine, long-term be used alone can cause a degree of damage to normal plant cells.It will be different
The effective component of the mechanism of action is reasonably compounded, and is that the damage that delays disease to develop drug resistance and reduce to host plant is non-
Normal effective common method, and can be according to the effect in production application, to judge that this compounding is synergistic effect or short of money
Anti- effect.But for jervine, Zhongshengmycin and the compounded combination of graphene oxide three, there has been no excessively related reports at present
Road.
Summary of the invention
The purpose of the invention is to overcome the above-mentioned deficiency of the prior art, a kind of killing for prevention and control bacterial soft rot of potato is provided
Bacteria composition, for the present invention by the way that graphene oxide and jervine, Zhongshengmycin to be used in compounding, three belongs to different role mechanism
Fungicide, mutual mixture will not generate conflict；There is good synergistic function in a certain range, preventive effect is higher than single
