Description
Technical field
The present invention relates to technical field of pesticide combination, particularly relate to a kind of bactericidal composition containing high-efficiency precision metalaxyl and fluoxastrobin.
Background technology
High-efficiency precision metalaxyl belongs to phenylamide; for efficient, low toxicity, low-residual, the lasting period is long, insecticide-applying way is diversified, the wide spectrum systemic fungicide of the equal excellence of protection and result for the treatment of; cauline leaf process, seed treatment and soil treatment can be made, have aobvious control efficiency of removing from office to the crop pest that downy mildew, phytophthora, pythium spp etc. cause.
Fluoxastrobin, belong to methoxy acrylic bactericide a kind of, be mainly used in cauline leaf process, there is quick-acting and lasting period long double grading, have good compatibility to crop, suitable processing formulation can further improve it enters people's leaf portion osmosis by cuticula.Fluoxastrobin application optimum period, is wide, no matter early stage as spore germination, germ tube growth and intrusion leaf portion at fungal infection, or can provide extraordinary protection and therapeutic action at growth period of hypha; But infect the most effective to spore germination and initial stage.The systemic activity of the excellence that cause has, it can be rapidly absorbed, and can transmit to top equably in leaf portion, therefore have the good resistance of rainwater washing against ability of root.Suitable for crop and safety cereal crop, potato, vegetables and coffee etc., under recommended dose to crop safety, to underground water, Environmental security.The phonetic mattress ester of controlling object fluorine has the bactericidal activity of wide spectrum, to nearly all Mycophytes (Ascomycetes, Basidiomycetes, Oomycete and Fungi Imperfecti) disease as the tens of kinds of diseases such as rust, clever blessing disease, net blotch, powdery mildew, downy mildew all have good activity.
In the real process of agricultural production, using chemical agent is the most effective means of control plant pest, but is the generation of disease drug resistance by the problem that chemical control disease the most easily produces.In the chemical control of bacteriosis, years of researches are carried out both at home and abroad, although some antibacterium medicaments have started to enter practical stage, but the medicament of chemosynthesis has cycle long, the shortcoming such as cost is high, toxicity is large, environmental pollution is serious, can not meet the requirement of agricultural sustainable development far away.And long-term use single pesticidal preparations continuously high dose, easily cause the problems such as the remaining of medicament, environmental pollution and resistance to pesticide resistance fungi development.And by contrast, exploitation is efficient with research, low toxicity, low-residual composite and mixture has small investment, the lead time is short and be subject to domestic and international attention, numerous and confused increasing develops dynamics.We are on the basis of lab screening and field trial, filter out high-efficiency precision metalaxyl and fluoxastrobin carries out composite, have obvious synergistic effect.And about high-efficiency precision metalaxyl and fluoxastrobin composite composition pesticide and apply and there is no people at present and reported.
Summary of the invention

Embodiment
For making technical scheme of the present invention, object and advantage are clearly understood, the following specific embodiment of the present invention is described, but the present invention is not limited to these examples.The mode that effect experimental of the present invention adopts indoor biometrics and field trial to combine, if no special instructions, the ratio below mentioned is all ratio of quality and the number of copies.
Embodiment: high-efficiency precision metalaxyl and fluoxastrobin different ratio co-toxicity are tested.
1.1 test targets
Never executed efficient Metalaxyl-M and fluoxastrobin and cucumber of the same type to gather potted plantly be separated, for examination cucumber variety: Chang Chun Mi Ci from Shouguang, Shandong.
1.2 test method
By susceptible cucumber variety Chang Chun Mi Ci cultivation in pot for growing seedlings, be placed in greenhouse and cultivate, plant grows to three to four leaf after dates, gathers the blade of identical leaf age, for cultivation and the mensuration of cucumber powdery mildew's pathogen.
1.2.1 the cultivation of cucumber powdery mildew's pathogen and the preparation of spore suspension
Cucumber powdery mildew's pathogen adopt plants method 20 DEG C, cultivate under the condition of 12h alternation of light and darkness, every 30d turns culture 1 time.With the conidium on sterile water wash-out incidence of leaf during inoculation, being mixed with spore concentration is l × 10
6the suspension of individual/mL.
1.2.2 strains tested sensitivity testing
Leaf dish moisturizing method is adopted to carry out toxicity test.First the blade of collection is prepared into the leaf dish that diameter is 1.5cm, random mixing, be placed in the series concentration liquid configured respectively and soak lh, each concentration 50 leaf dishes, test with the process of not adding medicine as blank, after immersion terminates, leaf faces up and puts on the blotting paper that identical liquor strength is wetting, liquid on leaf dish is blotted, the spore suspension l0L prepared is inoculated in leaf dish central authorities, room temperature is placed after 5min, is placed in 20 DEG C, cultivates under the condition of 12h alternation of light and darkness, measure the onset area on leaf dish after 10d, calculate EC
50.
On the basis of preliminary experiment, respectively toxicity test is carried out to single dose high-efficiency precision metalaxyl and fluoxastrobin in order to upper method, the two EC
50value is respectively 13.6574 ㎎/l and 10.2147 ㎎/l.
The percentage accounting for leaf disc area according to lesion area divides disease level
0 grade: anosis;
1 grade: sorus area accounts for less than 5% of whole leaf area;
3 grades: sorus area accounts for below the 6%-10% of whole leaf area;
5 grades: sorus area accounts for below the 11%-20% of whole leaf area;
7 grades: sorus area accounts for below the 21%-50% of whole leaf area;
9 grades: sorus area accounts for more than 50% of whole leaf area.
1.2.3 mixture toxicity test and interpretation of result
Carry out the toxicity test of mixture according to mixed ratio by single dose toxicity test method.
If contrast lethality <5%, does not correct, contrast lethality, between 5%-20%, corrects by formula 2, and contrast lethality >20%, test need be reformed.
Be independent variable x with the logarithm value of drug concentration (mg/L), with the probability value of corrected mortality for dependent variable y, set up virulence regression equation formula respectively, adopt DPS software to calculate the EC of single dose and each proportioning mixture
50co-toxicity coefficient (CTC) is calculated according to the abundant method of Sun Yun.Co-toxicity coefficient CTC, computing formula is as follows: (with high-efficiency precision metalaxyl for standard agent, its toxicity index is 100):
The EC of toxicity index (the TI)=high-efficiency precision metalaxyl of fluoxastrobin
50the EC of/fluoxastrobin
50× 100
The EC of true toxicity index (the ATI)=high-efficiency precision metalaxyl of M
50the EC of/M
50× 100
TI × P fluoxastrobin of TI × P high-efficiency precision metalaxyl+fluoxastrobin of theoretical toxicity index (the TTI)=high-efficiency precision metalaxyl of M
TTI × 100 of the ATI/M of co-toxicity coefficient (the CTC)=M of M
In formula:
M is the mixture of high-efficiency precision metalaxyl and fluoxastrobin different ratio
P high-efficiency precision metalaxyl is the ratio of high-efficiency precision metalaxyl shared by mixture
P fluoxastrobin is the ratio of fluoxastrobin shared by mixture.
2.1 toxicity test results
Table 1 high-efficiency precision metalaxyl and fluoxastrobin are to the toxicity test of powdery mildew of cucumber
As can be seen from the table, the result of the test of different proportion proportioning shows, dilute respectively in active ingredient ratio and all show stronger synergistic effect, wherein with high-efficiency precision metalaxyl: time fluoxastrobin is 1:20 ~ 20:1, synergistic effect is best, suggestion carries out further field control effectiveness test to suitable proportion about 1:20 ~ 20:1 mixture preparation, to evaluate its field practical application effect.
