The embodiment of the 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, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect, on this basis, carry out field trial again.
Test method: after each medicament establishment concentration range was determined in prerun, medicament was established respectively 5 dosage by active constituent content and is processed, and established the clear water contrast.Carry out with reference to " farm-chemical indoor determination test rule bactericide ", adopt the mycelial growth rate method to measure medicament to the virulence of crop germ.Measure colony diameter with the right-angled intersection method behind the 72h, 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 (x) to, tries to achieve virulence regression equation (y=a+bx) with method of least squares, and calculates thus the EC of every kind of medicament
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR＜0.5 is antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect.Computing formula is as follows:
Wherein: a, b are respectively active components A and active component B shared ratio in combination;
A is antibiotic in pyrimidine nucleoside class;
B is selected from a kind of in fluoxastrobin, ZEN 90160, kresoxim-methyl, azoles bacterium ester, the orysastrobin.
