The embodiment of the present invention is the method using Toxicity Determination and field test to combine.First pass through indoor virulence to survey
Fixed, after clear and definite two kinds of medicaments are compounding by a certain percentage potentiation ratio (SR), SR ＜ 0.5 is antagonism, 0.5≤SR≤1.5
For summation action, SR ＞ 1.5 is potentiation, on this basis, then carries out field test.
Test method: after prerun determines each medicament effective inhibition concentration scope, medicament is set 5 respectively by active constituent content
Individual dosage processes, if clear water comparison.Carry out with reference to " farm-chemical indoor determination test rule antibacterial ", use mycelial growth speed
Rate method measures the medicament virulence to crop pathogenic bacteria.Measure colony diameter by decussation method after 72h, calculate each process and only grow
Amount, 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) is converted into logarithm value (x), with minimum
Square law tries to achieve virulence regression equation (y=a+bx), and thus calculates the EC of every kind of medicament50Value.Simultaneously according to Wadley method
Calculating two medicaments different ratio synergy ratio (SR), SR ＜ 0.5 is antagonism, and 0.5≤SR≤1.5 are summation action,
SR ＞ 1.5 is potentiation.Computing formula is as follows:
