The sterilization composition has the following advantages that: 1, the sterilization spectrum is enlarged, the synergia effect is obvious, and the prevention and treatment effects are improved; 2, the zhongshengmycin and the fludioxonil are two medicaments with different action mechanisms, and the resistance risk is reduced when the zhongshengmycin and the fludioxonil are mixed and matched; and 3, the zhongshengmycin and the fludioxonil are compounded, the medicine effect is improved, the medication quantity is reduced, the medication cost is reduced, and the residue and the relative environment pollution are reduced.
Description
Technical field
The invention belongs to pesticide field, specifically is the bactericidal composition of giving birth to rhzomorph in a kind of containing.
Background technology
In recent years; Because unscientific tillage method and irrational medication; Field fungi disease and bacteriosis take place more and more serious, and like angular leaf spot of cucumber, root rot, fusarium wilt, bacterial wilt etc., the single use of medicament commonly used has been difficult to obtain the better prevention effect.
In to give birth to rhzomorph be a kind of biogenic N-glucosides class antibiotic, its has a broad antifungal spectrum, effective to various bacteria, fungi, particularly Gram-negative and positive bacterium are had very good effect; Its mechanism of action is to generate through the peptide bond that suppresses pathogenetic bacteria protein, finally causes bacterial death; Sprouting to the fungal pathogens spore has the strong inhibition effect, causes protoplasm cohesion in the hyphal cell, changes the mycelium shape, plays the effect of control fungal disease; Its effective object: has a broad antifungal spectrum; Ability resisting gram-positive and negative bacteria, mycobacterium, saccharomycete and filamentous fungi; Especially crops pathogenic bacteria such as soft rot of cabbage bacterium, angular leaf spot of cucumber bacterium, Xanthomonas oryzae, ring rot of apple bacterium etc. all had obvious antibacterial activity; Cost was higher when but middle living rhzomorph used separately, long-term single continuous use, and resistance risk is bigger.
Therefore, the synergistic composition of giving birth to rhzomorph during exploitation contains is significant, and synergistic composition can improve control efficiency on the one hand, reduces the control cost to a certain extent.Can avoid on the other hand or the generation speed of delaying drug resistance, prolong the service life of medicament, help the comprehensive regulation of disease.
Summary of the invention
The purpose of this invention is to provide a kind of being applicable to and prevent and treat crop bacteriosis and fungal disease, and resistance risk is low, a kind of bactericidal composition that contains middle living rhzomorph that preventive effect is good.
The technical scheme that the present invention solves the problems of the technologies described above is following:
Give birth to the bactericidal composition of rhzomorph in a kind of containing, active ingredient is middle living rhzomorph and fludioxonil, and the mass ratio of middle living rhzomorph and fludioxonil is 1～10: 50～1.Through preferred middle living rhzomorph and fludioxonil preferred mass ratio is 1～5: 30～1.

Bactericidal composition of the present invention also can use with other compound with sterilization, desinsection, also can nematocide, protective agent, growth regulator, nutrient for plants or soil conditioner mix and use.
Compared with prior art the present invention has following advantage:
1. synergistic effect is obvious, has improved control efficiency.
2. enlarged fungicidal spectrum: middle living rhzomorph is effective to bacteriosis, can be general to the fungal disease effect, and fludioxonil can only be prevented and treated fungus-caused disease, and the two is used with and can prevent and treat bacterium and fungi mixes the field disease that takes place.
3. middle living rhzomorph and fludioxonil are the medicaments of two kinds of different effects mechanism, are mixed between them, and resistance risk reduces.
4. middle living rhzomorph and fludioxonil are composite, and drug effect improves, and reduce dosage, reduce drug cost, have reduced residual and to the pollution of environment.
Embodiment
The inventor is through a large amount of screening tests and quantitative analysis, and living rhzomorph and fludioxonil are mixed in the certain proportion scope in the discovery, and various crop pathogenetic bacteria, fungi are had significant synergistic effect.
Fludioxonil is the non-interior benzene pyroles bactericide of inhaling, and high-efficiency broad spectrum has extraordinary preventive effect to microbial kind biography of many cause of diseases such as sac fungi, basidiomycetes, imperfect fungus and soil-borne disease.The mechanism of action mainly suppresses the relevant transfer of glucose phosphorylated with characteristics, and suppresses the growth of fungal mycelium, finally causes germ dead, and the mechanism of action that it is unique does not have cross resistance with other known bactericide.
The present composition is an active ingredient with middle living rhzomorph and fludioxonil, and both mechanisms of action are different, and combination has obvious role in synergism to watermelon rhizoctonia solani, tomato da mping-off fungi etc. between them, rather than the simple addition of two kinds of medicament effects.
Below in conjunction with biologicall test instance and embodiment the present invention is further described.
Biologicall test instance 1
Middle rhzomorph and the composite Toxicity Determination of fludioxonil of giving birth to the watermelon rhizoctonia solani
Subjects: watermelon damping off
Test method: the mycelial growth rate method is adopted in test.Test medicine is got the adding of 5ml soup and is equipped with in the conical flask of the hot medium of 45ml (PDA medium, 45-50 ℃) referring to table 1; After shaking up, pour diameter 90mm glass culture dish rapidly into, each culture dish is poured band medicine medium 12ml into; Each handles 4 repetitions; Level leaves standstill, cooling back flat board, be mixed into contrast with equivalent sterile water and medium.Cut the bacterium cake with diameter 5mm card punch from the confession examination bacterium edge of cultivating 2d, receive and be with on the malicious medium with choosing one side that pin will have a mycelia, all operations all carries out sterile working at superclean bench.Be placed on dark culturing in 24 ± 1 ℃ the constant temperature aseptic culture case after the processing, adopt the right-angled intersection method to measure the colony diameter that each is handled respectively behind the 2d, calculate mean value, the mycelial growth inhibition rate of colony diameter.
Calculate virulence regression equation and EC with Finney probit value method
50(mg/L).
Adopt the abundant method of Sun Yun to calculate the toxicity index of each medicament and the co-toxicity coefficient of mixture (CTC value), promptly
Actual measurement toxicity index (ATI)=standard medicament EC
50/ confession reagent agent EC
50* 100
The percentage composition of B in percentage composition+B medicament toxicity index * mixture of A in theoretical toxicity index (ATI)=A medicament toxicity index * mixture
Co-toxicity coefficient (CTC)=mixture actual measurement toxicity index (the ATI)/theoretical toxicity index (TTI) of mixture.
Evaluation criterion: co-toxicity coefficient (CTC)≤80 is for picking up anti-effect, and 80＜CTC＜120 are summation action, and CTC>=120 are synergistic effect.
Table 1 is the result show; In give birth to rhzomorph and fludioxonil proportioning 1～10: in the time of between 50～1, more than 120, especially proportioning is 1～5: have remarkable synergistic effect between 30～1 to the co-toxicity coefficient of watermelon damping off; Co-toxicity coefficient can improve the activity of medicament more than 200 through being mixed.
