Description
Technical field
The present invention relates to technical field of pesticide compounding, more particularly to a kind of sterilization group containing tetramycin and kasugarnycin
Close object.
Background technique
Tetramycin (tetramycin) is the fermentating metabolism product of S. ahygroscopicus Wuzhou subspecies, wide sterilization spectrum, to flagellum
Disease fungus known to main kind of 26 kinds of bacterium, sac fungus and Deuteromycotina fungi etc. three has extremely strong killing effect.It is suitable
With the prevention and treatment of a variety of fungies, bacteriosis of various crops.Especially to fruit tree putrefaction disease spot defoliation, rice blast, Soybean Root
Maize ear rot, cucurbits fusarium wilt, cotton verticillium wilt, jujube tree rust, fruit white rot of grape, Panax pseudoginseng black spot, tealeaves gall of tea, forest
The fungal diseases special efficacys such as rot disease, canker, bleeding disease, defoliation, woods seedling blight.
Kasugarnycin is a kind of one kind generated by little Jin actinomyces that Institute of Microorganism, Academia Sinica succeeds in developing
Biological bactericide has stronger absorbability, has the function of preventing and treating, therapeutic effect is more significant, for preventing and treating
The various bacteria and fungal disease of the crops such as vegetables, melon and fruit and rice；To rice blast, bacterial brown streak, tomato leaf
Mildew, gray mold, cucumber fusarium axysporum, bacterial angular leaf spot, anthracnose of sorghum, pepper bacterial scab disease, early blight of celery are sweet
Blue-black maize ear rot, Kidney bean are swooned blight, citrus, shatian pomelo canker significant effect.
In the real process of agricultural production, application chemical agent is prevention and treatment plant pest the most effective means, but
The problem of being most easily produced by chemical prevention disease is the generation of disease drug resistance.In the chemical control of bacteriosis,
Years of researches have been carried out both at home and abroad, although some antibacterium medicaments have begun into practical stage, chemistry is closed
At medicament have the shortcomings that the period is long, at high cost, toxicity is big, environmental pollution is serious, be far from satisfying agriculture sustainable development
The requirement of exhibition.And long-term continuous high dose apply single pesticidal preparations, be easy to cause residual, the environmental pollution of medicament with
And the problems such as drug-resistant fungi development.And in contrast, it develops and studies efficient, less toxic, low-residual compound and mixture tool
Have small investment, the lead time is short and is paid attention to both at home and abroad, increase developing efforts one after another.We screen indoors and field
It on the basis of test, filters out tetramycin and is compounded with kasugarnycin, there is apparent synergistic effect.And about tetramycin with
It has not been reported so far for the composition pesticide of the compounding of kasugarnycin and application.
Summary of the invention
Based on the above circumstances, it is an object of that present invention to provide a kind of new and effective composition pesticide, it is mainly used for preventing and treating
Fruit tree putrefaction disease, spot defoliation, rice blast, root rot, cucurbits fusarium wilt, cotton verticillium wilt, jujube tree rust, grape are white

Specific embodiment
To make technical solution of the present invention, purpose and advantage are more clearly understood, present invention following specific embodiments
It is illustrated, but the present invention is not limited to these examples.Effect experiment of the invention uses indoor biometrics and field trial phase
In conjunction with mode, unless otherwise instructed, ratio mentioned below is all mass parts ratio.
Embodiment: tetramycin and kasugarnycin virulence experiment with different proportions.
1.1 test targets
(germ strain picks up from the Qingdao of Shandong province town Jimo Yi Feng cucumber booth, Jing Haili to cucumber bacterial angular leaf spot bacterium
You isolate and purify and obtain in medicine company Group Plc's research and development centre's raw test room).
1.2 test method
15% tetramycin mother's medicine, 15% kasugarnycin mother's medicine, is provided by Chemical Co., Ltd. Shandong Hailier.It will purify
Slant tube strain in aqua sterilisa is added, be made into opportunistic pathogen suspension, then be diluted to 107/liter bacteria suspensions, it is spare.It is first mould by four
It is made into 1000mg/L mother liquor after element and the dissolution of kasugarnycin mother medicinal sterile water, is diluted using Shi Zaiyong sterile water.(unit: milli
Grams per liter)
Tetramycin is mixed with kasugarnycin to set 5 groups of proportions altogether, on the basis of preliminary experiment, each single dose and each matches
Than setting 5 concentration processing respectively, using the system without medical fluid as blank control (maximum concentration referring to chemicals treatment dilutes).Often
A concentration processing is repeated 4 times, and under aseptic technique, each concentration gradient medicament is successively inhaled from low concentration to high concentration respectively
4ml is taken, is added in the sterile conical flask of the sterilising medium containing 36ml melted in advance, is sufficiently shaken up, pour into diameter immediately after
In the culture dish of 9cm, corresponding drug containing tablet is made.Every ware is added 107/liter bacterial suspension, 200 μ l, then with three after sterilizing
Angle glass bar pushes away bacteria suspension in ware even, is placed in 28 DEG C of insulating boxs and cultivates.Separately the processing without medicament is set as 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 (1960) Sun&Johnson
≤ 80 be antagonism, and 80 < CTC < 120 are summation action, and CTC >=120 are synergistic effect.
Survey toxicity index (ATI)=standard agent EC50/ reagent agent EC50*100
Percentage composition+medicament B of A medicament in mixtures theoretical toxicity index (TTI)=medicament A 100 mixture of toxicity index *
100 mixture of toxicity index * in B medicament percentage composition
Co-toxicity coefficient (CTC)=mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI) * 100.
2.1 toxicity test results
The toxicity test of 1 tetramycin of table and kasugarnycin to cucumber bacterial angular leaf spot bacterium
As can be seen from the table, the test result of different proportion proportion shows to dilute equal table respectively in effective component ratio
Reveal stronger synergistic effect, wherein with tetramycin: synergistic effect is best when kasugarnycin is 1:20~20:1, it is proposed that right
Suitable proportion 1:20~20:1 or so mixture preparation carries out further field control effectiveness test, to evaluate its field practical application effect
Fruit.
3 field trials prevent and treat bacterial blight of rice, the experimental result of cucumber bacterial angular leaf spot
3, field trial prevents and treats bacterial blight of rice
3.1.1 test method
In the Qingdao of Shandong province town Jimo Yi Feng paddy base, test variety is hybrid rice variety for test, every processing 4 times
It repeats, every cell double diagonal line investigates 5 points, and five plants of whole blades when investigation, a situation arises for statistics disease.
Occurring degree is recorded with staging, grade scale is as follows:
0 grade: disease-free；
1 grade: scab heap area accounts for the 5% or less of whole leaf area；
3 grades: scab heap area accounts for the 6%-10% or less of whole leaf area；
