The embodiment of the present invention is the method being combined using Toxicity Determination and field trial.First pass through indoor virulence survey
It is fixed, the synergy ratio (SR) after two kinds of medicaments compound by a certain percentage is defined, SR ＜ 0.5 are antagonism, 0.5≤SR≤1.5
For summation action, SR ＞ 1.5 are synergistic effect, on this basis, then carry out field trial.
Test method：After prerun determines the effective inhibition concentration range of each medicament, medicament sets 5 respectively by active constituent content
A dosage processing, if clear water compares.Reference《Farm-chemical indoor determination test rule fungicide》It carries out, speed is grown using mycelia
Rate method measures virulence of the medicament to crop germ.Colony diameter is measured with crossing method after 72h, calculates the net growth of each processing
Amount, mycelial growth inhibition rate.
Net growth (mm)=measurement colony diameter -5
Mycelial growth inhibition rate is converted into probit value (y), liquor strength (μ g/mL) is converted into logarithm (x), with minimum
Square law acquires virulence regression equation (y=a+bx), and thus calculates the EC of each medicament50Value.Simultaneously according to Wadley methods
Two medicament different ratio synergy ratios (SR) are calculated, SR ＜ 0.5 are antagonism, and 0.5≤SR≤1.5 are summation action,
SR ＞ 1.5 are synergistic effect.Calculation formula is as follows：
Wherein：A, b is respectively active components A and active constituent B ratio shared in combination；
A is dimoxystrobin；
B is selected from one of Tebuconazole, tricyclazole, epoxiconazole, propiconazole, prothioconazoles kind.
