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.
Test method: after the effective inhibition concentration scope of each medicament is determined in prerun, medicament is established respectively 5 dosage processing by active constituent content, establishes clear water contrast.Carry out with reference to " farm-chemical indoor determination test rule bactericide ", adopt mycelial growth rate method to measure the virulence of medicament to crop germ.After 72h, measure colony diameter by right-angled intersection method, calculate each processing 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), 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 of two medicaments (SR) according to Wadley method, 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 components A and active component B shared ratio in combination;
A is azoles mepanipyrim;
B is selected from the one in thiophanate-methyl, cyazofamid, fluorine bacterium azoles, Fenamidone, carbendazim, Prochloraz or its salt.
