The expected efficacy (calculated efficacy) of the composition was determined using the Colby formula (see r.s. Colby, Weeds (Weeds), 1967, 15, 20-22) and compared to the observed efficacy.
E＝X+Y–XY/100
In the formula:
e: the expected efficacy (calculated efficacy in the tables below) when using the combination of active components a and B at concentrations a and B, expressed as% of the untreated control;
x: the efficacy of active ingredient a at the concentration a used, expressed as% of the untreated control;
