Description
Technical field
The present invention relates to technical field of pesticide combination, more particularly to a kind of bactericidal composition containing amino-oligosaccharide.
Background technology
Compound A wide sterilization spectrums, to known to main kind of 26 kinds of mastigomycetes, sac fungus and Deuteromycotina fungi etc. three
Disease fungus has extremely strong killing action.The preventing and treating of a variety of fungies, bacteriosis of various crops is applicable, to virosis effect
It is excellent.Especially to fruit tree putrefaction disease spot defoliation；Rice blast；Root rot；Cucurbits fusarium wilt；Cotton verticillium wilt；Jujube tree
Rust；Fruit white rot of grape；Panax pseudoginseng black spot；Tealeaves gall of tea, forest rot, canker, bleeding disease, defoliation, woods
The fungal disease special efficacy such as seedling blight.
Compound A mainly includes following compound：
(1S, 3S)-N '-(4- chlorobenzenes methylene) -1- methyl -2,3,4,9- tetrahydropyridines simultaneously [3,4-b] indoles -3- first
Hydrazides (Formulas I) and (1S, 3S)-N '-(cyclohexylmethylene) -1- methyl -2,3,4,9- tetrahydropyridines simultaneously [3,4-b] indoles -3-
Formylhydrazine (Formula II).
Amino-oligosaccharide (chitosan oligosaccharide) refers to D- Glucosamines with the oligosaccharide of β -1.4 glucosides key connections, by chitin
Matter is degraded to degrade again after chitosan less toxic bactericide that is obtained, or being extracted by microbial fermentation.Amino-oligosaccharide (agriculture level shell
Oligosaccharides) can be to some germs growth produce inhibitory action, influence fungus spore germination, induce hypha form morph, spore
Interior biochemistry changes.Can excite gene in plant, produce the chitinase with resistant effect, dextranase, protect element and
PR albumen etc., and with cell activation effect, contribute to the recovery of aggrieved plant, promoting root growth strong sprout, strengthen the resistance of crop, promote
Enter growth and development of plants.Amino-oligosaccharide solution, there is antivirus, bactericidal, fungicidal action, not only to fungi, bacterium, virus
With extremely strong preventing and treating and eradicant action, but also there is the effect of nutrition, regulation, removing toxic substances, antibacterial, can be widely used for preventing and treating fruit
Tree, vegetables, underground rhizome, tobacco, the virus of Chinese medicine and grain and cotton crop, bacterium, fungus-caused mosaic disease, little leaf, spot
The diseases such as point disease, anthracnose, downy mildew, epidemic disease, blight dis-ease, BYDV, rice blast, bacterial wilt, soft rot.
It is to prevent and treat the maximally efficient means of plant pest using chemical agent in the real process of agricultural production, but
It is easiest to generate the problem that the generation of disease drug resistance by chemical prevention disease.In the chemical control of bacteriosis,
Years of researches have been carried out both at home and abroad, although some antibacterium medicaments have begun to enter practical stage, chemistry closes
Into medicament have the shortcomings that the cycle is long, cost is high, toxicity is big, environmental pollution is serious, agriculture sustainable development far can not be met
The requirement of exhibition.And long-term continuous high dose apply single pesticidal preparations, easily cause residual, the environmental pollution of medicament with
And the problems such as resistance to resistance to the action of a drug fungi development.And by contrast, exploitation has with studying efficient, low toxicity, the compounding of low-residual and mixture
Have small investment, the lead time is short and is paid attention to both at home and abroad, numerous and confused increase develops dynamics.We screen indoors and field
On the basis of experiment, filter out compound A and compounded with amino-oligosaccharide, there is obvious synergistic effect.And on chemical combination
The composition pesticide of the compounding of thing A and amino-oligosaccharide and application there is no people to report at present.
The content of the invention
Based on case above, present invention aims at a kind of new and effective composition pesticide is provided, can be widely used for preventing
Control the virus of fruit tree, vegetables, underground rhizome, tobacco, Chinese medicine and grain and cotton crop, bacterium, fungus-caused mosaic disease, leaflet
Disease, spot disease, anthracnose, downy mildew, epidemic disease, blight dis-ease, BYDV, rice blast, bacterial wilt, soft rot, rot；Root-rot
The diseases such as disease, droop.
Technical scheme of the present invention is realized by following measures：A kind of Bactericidal composite containing amino-oligosaccharide
Thing, the bactericidal composition include active ingredient and auxiliary element, and wherein active ingredient is compound A and amino-oligosaccharide, is had

Research and development centre of department laboratory isolates and purifies and obtained).
1.2 test method
15% compound mother's A medicine, 90% amino-oligosaccharide mother's medicine, is provided by Chambroad Agrochemical Technology Co., Ltd..Will
Aqua sterilisa is added in the slant tube strain purified, is made into opportunistic pathogen suspension, then is diluted to 107/liter bacteria suspensions, it is standby.First
It will be made into 1000mg/L mother liquors after the dissolving of compound A and amino-oligosaccharide mother's medicinal sterile water, be diluted again with sterilized water during use.
(unit：Mg/litre) compound A it is mixed with amino-oligosaccharide altogether setting 5 assemble ratio, on the basis of pilot study, each single dose
It is blank control (with reference to the most highly concentrated of chemicals treatment using the system without decoction and each proportioning sets 5 concentration processing respectively
Degree dilution).Each concentration processing is repeated 4 times, under aseptic technique, by each concentration gradient medicament respectively from low concentration to height
Concentration draws 4ml successively, adds in the sterile conical flask of advance thawing of the sterilising medium containing 36ml, fully shakes up, Ran Houli
Pour into diameter 9cm culture dish, corresponding drug containing flat board is made.The μ l of 107/liter bacterial suspension 200 are added per ware, then are used
Triangular glass rod after sterilizing pushes away bacteria suspension in ware even, is placed in 28 DEG C of insulating boxs and cultivates.The another processing set without medicament is made
For blank control.Each processing is repeated 4 times.
1.3 investigation method
Culture took out culture dish after 48 hours, according to blank control, observed bacteria colony count in each ware of each concentration.
Relative inhibition is calculated according to each processing bacteria colony count：
1.4 synegism evaluation
The synergistic effect of pharmacy mix, i.e. CTC are evaluated according to the co-toxicity coefficient method (CTC) of Sun＆Johnson (1960)
≤ 80 be antagonism, and 80 ＜ CTC ＜ 120 are summation action, and CTC >=120 are synergistic effect.
Survey toxicity index (ATI)=standard agent EC50/ reagent agents EC50*100
Percentage composition+medicament B of A medicaments in mixture theoretical toxicity index (the TTI)=medicament A mixtures of toxicity index * 100
The mixtures of toxicity index * 100 in B medicaments percentage composition
Co-toxicity coefficient (CTC)=mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI) * 100.
