Description
The application is for dividing an application, and original application is the patent application " a kind of bactericidal composition that contains cyazofamid and triazole class compounds " of Shaanxi Mei Bang agricultural chemicals Co., Ltd, and the application number of original application is ︰ 201110046416.3, and original application day is 2011.2.25.
Technical field
The invention belongs to technical field of pesticide, relate to the application of a kind of bactericidal composition that contains cyazofamid and triazole class compounds in crop pest.
Technical background
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.
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.
No matter be cyazofamid, effective active composition B or other efficient germicides, long-term use separately, easily makes disease develop immunity to drugs, and causes the problems such as dosage increasing, preventive effect reduction, lasting period shortening, is unfavorable for environment sustainable development.The active ingredient of the different mechanisms of action is carried out composite, is to delay the disease conventional method that develops immunity to drugs, and according to the effect in production application, judge this composite be synergistic effect or antagonism.Complex role is significantly filled a prescription, and can obviously improve preventive effect, greatly reduces the dosage of agricultural chemicals, also can expand fungicidal spectrum, improves germicidal efficiency, alleviates the pollution to environment.Cyazofamid is different from the effective active composition B mechanism of action, mutually composite have good synergistic effect within the specific limits, and relevant Tebuconazole, glyoxalin, bitertanol, kind bacterium azoles, metconazole, triticonazole, RH-7592, Difenoconazole is relevant composite, there is not yet at present relevant report at home and abroad.

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 in Tebuconazole, glyoxalin, bitertanol, kind bacterium azoles, metconazole, triticonazole, RH-7592, Difenoconazole) 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 active component B(Tebuconazole, glyoxalin, bitertanol, kind bacterium azoles, metconazole, triticonazole, RH-7592, Difenoconazole) shared ratio in combination;
A is cyazofamid;
B be Tebuconazole, glyoxalin, bitertanol, kind bacterium azoles, metconazole, triticonazole,
A kind of in RH-7592, Difenoconazole.
