3a-3d, embodiment 63, embodiment 107-110, reference substance 4a-4d.
(2) content is tested
After determining the effective inhibition concentration scope of each medicament through prerun, each medicament is set at 5 dosage respectively by active constituent content
Reason, if clear water is compareed.Reference《Farm-chemical indoor determination test rule bactericide》Carry out, determined using mycelial growth rate method
Virulence of the medicament to crop germ.Colony diameter is measured with crossing method after 72hr, each processing net growth, mycelia life is calculated
Long inhibiting rate.
Net growth (mm)=measurement colony diameter -5；
Mycelial growth inhibition rate (%)=100* (control group net growth-treatment group net growth)/control group net growth；
Mycelial growth inhibition rate is converted into probit value (y), liquor strength (μ g/mL) is converted into logarithm value (x), with least square
Method tries to achieve virulence regression equation (y=a+bx), and thus calculates the EC of every kind of medicament50Value.Calculated simultaneously according to Wadley methods
Two medicament different ratio synergy ratios (SR), SR ＜ 0.5 are antagonism, and 0.5≤SR≤1.5 are summation action, SR ＞
1.5 be synergistic effect.Calculation formula is as follows：SR=EC50(theoretical value)/EC50(observed value), EC50(theoretical value)=(a+b)/
[(a/A EC50)+(b/B EC50)], wherein：A, b are respectively active component fluopicolide and B (ZJ0712, pyrazoles ether bacterium
Ester) ratio shared in combination, A is fluopicolide, and B is pyraclostrobin.
