For summation action, SR ＞ 1.5 are synergistic effect, on this basis, then carry out field test.
Test method：After prerun determines the effective inhibition concentration scope of each medicament, medicament sets 5 respectively by active constituent content
Individual dosage processing, if clear water compares.Reference《Farm-chemical indoor determination test rule bactericide》Carry out, using mycelial growth speed
Rate method determines 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 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 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 component B ratio shared in combination；
