Description

A kind of bactericidal composition that contains fluorine pyrrole bacterium acid amides and pyraclostrobin
Technical field
The present invention relates to agriculture chemical compounding technical field, particularly relate to a kind of bactericidal composition that contains fluorine pyrrole bacterium acid amides and pyraclostrobin.
Background technology
Fluorine pyrrole bacterium acid amides is a kind of new benzamides series bactericidal agent, and its chemical name is the chloro-5-(trifluoromethyl of N-{2-(3-)-2-pyridine radicals) ethyl-

-tri-fluoro-O-toluamides }, by hindering the electronics transfer of succinate dehydrogenase in respiratory chain, suppress mitochondrial respiratory.Be mainly used in preventing and treating on broad leaf crop the microbial disease of capsule.To the downy mildew on the vegetables such as cucumber, custard squash, powdery mildew, the downy mildew of fruit tree etc. causes that by germ multiple diseases has favorable effect.
Pyraclostrobin (pyraclostrobin) is the New-type wide-spectrum bactericide of BASF AG's latest model methoxy acrylic, its chemical name is that N-f2 mono-" 1 one (4 monochloro-benzene) 1H-pyrazoles-3-yloxymethyl " benzene is foretold N mono-methoxy methyl carbamate, and the mechanism of action of pyraclostrobin is mitochondrial respiratory inhibitor. by stoping electronics to shift in cytochrome b cl is synthetic.There is protection, treatment, blade infiltration conduction.Pyraclostrobin missible oil shows that through field control effectiveness test result powdery mildew of cucumber, downy mildew and banana freckle, leaf spot are had to good control efficiency.
In the real process of agricultural production, using chemical agent is the most effectively means of control plant pest, but the problem the most easily producing by chemical control 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 started to enter practical stage, but the medicament of chemosynthesis has long, the shortcoming such as cost is high, toxicity is large, environmental pollution is serious of cycle, 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 residual, the environmental pollution of medicament and resistance to pesticide resistance fungi development.And by contrast, exploitation is efficient with research, low toxicity, low-residual composite be mixed there is small investment, the lead time is short and be subject to domestic and international attention, the numerous and confused dynamics that develops that strengthens.We filter out fluorine pyrrole bacterium acid amides and pyraclostrobin and carry out compositely on the basis of lab screening and field trial, have obvious synergistic effect.And about the composite composition pesticide of fluorine pyrrole bacterium acid amides and pyraclostrobin and application, there is no at present people reported.

1.2 test targets
From Shouguang, Shandong, never executed fluorine pyrrole bacterium acid amides and pyraclostrobin and cucumber of the same type gather potted plantly separated, for examination cucumber variety: Chang Chun Mi Ci.
1.3 test method
1.3.1 medicament preparation
First use the former medicine of acetone solution, according to the result of preliminary experiment, two appropriate former medicines are made into several different proportionings, then it is stand-by with acetone, each processing to be diluted to respectively to several concentration gradients.
Susceptible cucumber variety Chang Chun Mi Ci cultivation, in pot for growing seedlings, is placed in to greenhouse and cultivates, and plant grows to three to four leaf after dates, gathers the blade of identical leaf age, for cultivation and the mensuration of gray mold of cucumber germ.
1.3.2 the cultivation of gray mold of cucumber germ and the preparation of spore suspension
Gray mold of cucumber germ adopts plants method to cultivate under 20 ℃, the condition of 12h alternation of light and darkness, and every 30 d turn culture 1 time.During inoculation, with the conidium on sterile water wash-out incidence of leaf, being mixed with spore concentration is l * 10 6the suspension of individual/mL.
1.3.3 strains tested sensitivity testing
Adopt leaf dish moisturizing method to carry out toxicity test.First the blade of collection is prepared into the leaf dish that diameter is 1.5cm, mix at random, be placed in respectively the series concentration liquid configuring and soak lh, 50 leaf dishes of each concentration, test is with the blank that is treated to of adding medicine not, after immersion finishes, leaf faces up and puts on the wetting blotting paper of identical liquor strength, liquid on leaf dish is blotted, the spore suspension l0L preparing is inoculated in to leaf dish central authorities, and room temperature is placed after 5 min, is placed under 20 ℃, the condition of 1 2h alternation of light and darkness and cultivates, after 10d, measure the onset area on leaf dish, calculate EC 50.
The percentage that accounts for leaf disc area according to lesion area is divided sick level
0 grade: anosis;
1 grade: sorus area accounts for below 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 the more than 50% of whole leaf area;
1.3.4 mixture toxicity test and interpretation of result
By single dose toxicity test method, according to mixed ratio, carry out the toxicity test of mixture.
If contrast lethality <5%, does not proofread and correct, contrast lethality, between 5%-20%, is proofreaied and correct by formula 2, contrast lethality >20%, and test need be reformed.
The logarithm value of drug concentration (mg/L) of take is independent variable x, and the probability value of corrected mortality of take is dependent variable y, sets up respectively virulence regression equation formula, adopts DPS software to calculate the EC of single dose and each proportioning mixture 50according to the abundant method of Sun Yun, calculate co-toxicity coefficient (CTC).Co-toxicity coefficient CTC, computing formula is as follows: (the fluorine pyrrole bacterium acid amides of take is standard medicament, and its toxicity index is 100):
The EC of the toxicity index of pyraclostrobin (TI)=fluorine pyrrole bacterium acid amides 50the EC of/pyraclostrobin 50* 100
The EC of true toxicity index (ATI)=fluorine pyrrole bacterium acid amides of M 50the EC of/M 50* 100
TI * P pyraclostrobin of TI * P fluorine pyrrole bacterium acid amides+pyraclostrobin of theoretical toxicity index (TTI)=fluorine pyrrole bacterium acid amides of M
TTI * 100 of the ATI/M of the co-toxicity coefficient of M (CTC)=M
In formula:
M is fluorine pyrrole bacterium acid amides and the mixture of the different proportionings of pyraclostrobin
P fluorine pyrrole bacterium acid amides is fluorine pyrrole bacterium acid amides shared ratio in mixture
P pyraclostrobin is pyraclostrobin shared ratio in mixture.
2.1 toxicity test results
Table 1 fluorine pyrrole bacterium acid amides and the toxicity test of pyraclostrobin to gray mold of cucumber
Figure 394691DEST_PATH_IMAGE003
As can be seen from the table, the result of the test of different proportion proportioning shows, in active ingredient ratio, dilute respectively and all show stronger synergistic effect, wherein take fluorine pyrrole bacterium acid amides: pyraclostrobin as 1:10~10:1 time synergistic effect best, suggestion is carried out further field control effectiveness test to suitable proportion 1:10~10:1 left and right mixture preparation, to evaluate its field practical application effect.
