biological test example
When the effect of active compound combinations exceedes the summation of the effect when each reactive compound is used separately, there is collaborative desinsection and acaricidal action.The predictive role of the particular combination of two kinds of reactive compounds can use so-called " Colby formula " (see S.R. Colby, " Calculating Synergistic and Antagonistic Responses of Herbicide Combinations ", Weeds 1967,15,20-22) calculate as follows: if
X is the kill ratio when using the reactive compound A that consumption is m ppm for m g/ha or concentration, is expressed as the percentage accounting for untreated control,
Y is the kill ratio when using the reactive compound B that consumption is nppm for n g/ha or concentration, is expressed as the percentage accounting for untreated control,
E is when using consumption for kill ratio during m and n g/ha or the concentration reactive compound A and B that is m and n ppm, being expressed as the percentage accounting for untreated control, so
If the desinsection lethality rate of reality exceedes calculated value, then the lethal effect of composition be super add and, namely there is synergy.In this case, the kill ratio actually observed must be over the value of the expection kill ratio value (E) using above-mentioned formulae discovery.
