(2) sterilization biological test
There will be three kinds of situations: antagonism, addition and potentiation after active compound, generally when the effect summation acted on when each reactive compound is individually used of active compound combinations, namely it is believed that active compound exists synergistic function. The predictive role of reactive compound by Colby formula calculate (CalculatingSynergisticandAntagonisticResponsesofHerbicid eCombination ", Colby, S.R.; Weeds15,20-22,1967):
X=is when using preventive effect during active component A with the amount of application of mppm, being expressed as the percentage ratio of untreated control group;
Y=is when using preventive effect during active component B with the amount of application of nppm, being expressed as the percentage ratio of untreated control group;
E=is when using preventive effect when active component A and B with the amount of application of m and nppm, being expressed as the percentage ratio of untreated control group.
If the preventive effect of reality is higher than value of calculation, then the preventive effect of conjugate has superadditivity, namely there is synergy. In this case, the preventive effect actually observed must exceed the expection preventive effect (E) adopting above formula to calculate. That is, if it is observed that activity more than from the intended activity of Colby formula, then there is synergy.
