Description
Technical field
The present invention relates to a kind of bactericidal composition and application thereof, especially a kind of bactericidal composition containing metrafenone and pyraclostrobin and application thereof.
Background technology
Metrafenone (Metrafenone), chemical name: 3 ＇-bromo-2,3,4,6 ＇-tetramethoxy-2 ＇, 6-dimethyl benzophenone, molecular formula: C19H21BrO5.Structural formula is as follows:
Metrafenone belongs to Benzophenones antibacterial, the mechanism of action is growth and the formation of attachment spore during by interference spore germination, inhibit the spore germination of powdery mildew, simultaneously, by disturbing foundation and the formation of polarity actin tissue, hinder mycelial normal development and growth, efficiently control disease, there is obvious preventive and therapeutic action.It is mainly used in the preventing and treating of ascomycetes disease, such as powdery mildew of cucumber.
Pyraclostrobin (Pyraclostrobin), chemical name: methyl (N)-[[[1-(4-chlorobenzene) pyrazoles-3 base)-oxygen]-0-methoxyl group]-N-methoxymethyl carbamate, molecular formula: C19H18ClN3O4, chemical structural formula is as follows:
Pyraclostrobin belongs to methoxy acrylic bactericide.The mechanism of action is as a kind of mitochondrial respiratory inhibitor, by stoping electron transmission between cytochrome b and C1 to suppress mitochondrial respiratory effect, make mitochondrion can not produce and provide the energy (ATP) required for cell homergy, ultimately result in cell death.Pyraclostrobin has stronger suppression pathogenic bacteria spore germination ability, and mycelial growth in blade is had good inhibiting effect.There is protective effect, therapeutical effect, Uptake and translocation and resistance of rainwater washing against performance, and range of application is wider, it is possible to the disease that preventing and treating is caused by multiple fungal pathogen.
The industrial crops cultivated areas such as the difficulty of prevention and cure of current phytopathogen is increasing, on the one hand, along with the change of pattern of farming, melon fruits and vegetables progressively expand, and disease occurrence degree, occur quantity all to increase, and in preventing and treating, difficulty strengthens；On the other hand, the resistance of pathogen rises year by year under lasting medicament selection pressure, and the prevention effect of single dose is had a greatly reduced quality, and control of plant disease is faced with significant challenge.
Summary of the invention

One, indoor biometrics test
In indoor employing mycelial growth rate method, measure the different agents EC to bacterial strain50Value, by co-toxicity coefficient computational methods, calculates the co-toxicity coefficient (CTC) of mixture, it is determined that mixture building performance, and circular is as follows:
In mixture, a certain single dose (is generally selected EC for standard agent50Junior), it is calculated:
Single dose toxicity index=standard agent EC50/ certain single dose EC50×100
Toxicity index × A single dose the toxicity index of proportion+B single dose × B single dose proportion in mixture in mixture of theoretical toxicity index=A single dose
The EC of actual measurement toxicity index=standard single dose50The EC of value/mixture50Value × 100
Co-toxicity coefficient=actual measurement toxicity index/theory toxicity index × 100
When co-toxicity coefficient classification: CTC is more than 120, mixture has synergetic, is antagonism when CTC is less than 80, and CTC is summation action between 80-120.
The table 1 metrafenone+pyraclostrobin different ratio indoor biometrics result to powdery mildew of cucumber
Result of the test illustrates, metrafenone prevents and kill off powdery mildew of cucumber with pyraclostrobin is composite, all has potentiation in said ratio, and wherein the potentiation of proportioning 1:2 is the most notable.
Two, field control effectiveness test
Indoor biometrics shows good Pesticidal composition, the field medicine effect test of reality must be carried out, field medicine effect test is the important means that whether final evaluation Pesticidal composition has using value under the impact of field integrated environment, therefore, need the pesticide mixed preparation prepared by embodiment on the basis of indoor biometrics to carry out preventing and treating the field medicine effect test of powdery mildew of cucumber, compare metrafenone and the pyraclostrobin different ratio preventive effect to powdery mildew of cucumber.Each plot area is 66.7m2, in test treatment region, adopt accidental sampling, sample 7 points, 0.5 square metre every, check powdery mildew of cucumber occurrence degree.Comparison medicament is 100g/L metrafenone SC, 25% pyraclostrobin EC.
The table 2 metrafenone pyraclostrobin different ratio field control effectiveness test to powdery mildew of cucumber
Table 2 shows that powdery mildew of cucumber is had good prevention effect by metrafenone pyraclostrobin different ratio, and effect uses significantly better than single dose, has and significantly coordinates potentiation.
Shown by the result of indoor biometrics and field control effectiveness test, metrafenone and pyraclostrobin compositions have obvious synergistic function, powdery mildew of cucumber has excellent prevention effect, and prevention effect is all better than single dose kind, has good using value in agricultural is applied.
