Description
The application is for dividing an application, original application is the patent application " a kind of bactericidal composition containing cyazofamid and methoxy acrylic ester compounds " of Shaanxi Mei Bang agricultural chemicals Co., Ltd, the application number of original application is ︰ 201010614659.8, and original application day is 2010.12.30.
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition containing cyazofamid and methoxy acrylic ester compounds.
Background technology
Cyazofamid (cyazofamid), molecular formula is C
13h
13clN
4o
2s, chemical name is: the chloro-2-cyano group-N of 4-, N-dimethyl-5-p-methylphenyl imidazoles-1-sulfonamide; Cyanogen azoles flusulfamide, structural formula is:
Sulphaguanidine azoles fungicide.Oomycete fungi is had to very high biologically active as the plasmodiophora brassica bacteria of phytophthora, downy mildew, false downy mildew, pythium spp and Plasmodiophoromycetes.Mechanism of action is mitochondrial cytochrome b c in blocking-up Oomycete germ body
1the electronics transmission of complex carrys out the supply of interfering energy, the Q that its binding site is enzyme
1center, with other bactericide without cross tolerance.It may be because target enzyme causes the sensitivity difference of medicament that its height to pathogen is selected activity.Field application has high control efficiency to late blight and downy mildew, and using dosage is lower 2～38 times than other bactericide, and as the concentration with 50～100mg/L, processing potato late blight has outstanding control efficiency, and the medication phase is flexible, the lasting period is long.The downy mildew of processing grape, cucumber, muskmelon by same concentration, also has fabulous control efficiency.This medicament can extend the plant growth time, and makes increasing both production and income.For tomato, be improved the effect of quality.Access times are no more than 4 times, and using method is foliar spray.Exceeding under the concentration for the treatment of of 4 times of actual amount, having no poisoning report.Just at expanding prevention object, comprise pimento epidemic disease, ground rot of water melon, the sick downy mildew of great Bai, onion downy mildew and other diseases at present.
Yet in the real process of agricultural production, preventing and treating the problem that disease the most easily produces is the drug-fast generation of germ.Different cultivars composition carries out composite, is to prevent and treat the very common method of resistance germ.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals is all additive effect, really has the seldom composite of synergistic effect, especially synergistic effect very obviously, synergy ratio very high composite just still less.Through inventor's research, after discovery is composite by cyazofamid and Fluoxastrobin, kresoxim-methyl, ZJ0712, ZEN 90160, Enestroburin, can produce good synergistic effect, and not yet open about the composite relevant report of cyazofamid and Fluoxastrobin, kresoxim-methyl, ZJ0712, ZEN 90160, Enestroburin.

The embodiment of the present invention is the method that adopts Toxicity Determination and field trial to combine.The embodiment of the present invention is the method that adopts Toxicity Determination and field trial to combine.First by Toxicity Determination, the synergy ratio (SR) after clear and definite two kinds of medicaments are composite by a certain percentage, SR < 0.5 is antagonism, 0.5≤SR≤1.5 are summation action, SR > 1.5 is synergistic effect, on this basis, then carries out field trial.
Cyazofamid and active component B(B are selected from a kind of of Fluoxastrobin, kresoxim-methyl, ZJ0712, ZEN 90160, Enestroburin) composite to crop pest Toxicity Determination.
After the effective inhibition concentration scope of each medicament is determined in prerun, each medicament is established respectively 5 dosage by active constituent content and is processed, and establishes clear water contrast.With reference to < < farm-chemical indoor determination test rule bactericide > >, carry out, adopt mycelial growth rate method to measure the virulence of medicament to crop germ.After 72h, by right-angled intersection method, measure colony diameter, calculate and respectively process net growth, mycelial growth inhibition rate.
Net growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (μ g/mL) converts logarithm value to (x), with method of least squares, tries to achieve virulence regression equation (y=a+bx), and calculates thus the EC of every kind of medicament
50value.According to Wadley method, calculate the different proportioning synergy ratio (SR) of two medicaments, SR < 0.5 is antagonism simultaneously, and 0.5≤SR≤1.5 are summation action, and SR > 1.5 is synergistic effect.Computing formula is as follows:
Wherein: a, b are respectively active component cyazofamid and B(Fluoxastrobin, kresoxim-methyl, ZJ0712, ZEN 90160, Enestroburin) shared ratio in combination;
A is cyazofamid;
B is a kind of in Fluoxastrobin, kresoxim-methyl, ZJ0712, ZEN 90160, Enestroburin.Implementation of an application example two: cyazofamid and azoxystrobin compound are to peronophythora litchi Toxicity Determination.
Test medicine provides by Shaanxi Mei Bang agricultural chemicals Co., Ltd.
Experimental scheme: effective inhibition concentration scope of determining cyazofamid, the former medicine of Fluoxastrobin and the two different proportioning mixture through preliminary experiment.
Toxicity test result
Table 1 cyazofamid, Fluoxastrobin and the composite toxicity test analysis of results table to peronophythora litchi thereof
