Evaluation to the mixed potentiation for applying middle display of two or more herbicidal active components is based on “CalculationSynergistic and Antagonistic Response of Herbicide Combinations” What Colby ' the s methods described in (Weeds 15/1 (1967), S.R.Colby) determined.

In formula, X is fresh weight inhibition of the promazine Sulfometuron Methyl with certain dosage when alone to target weeds.

Y is that the chlorine sodium of 2 first 4 or the different monooctyl ester of the chlorine of 2 first 4 are suppressed when alone with certain dosage to the fresh weight of target weeds Rate.

E₀For promazine Sulfometuron Methyl and the chlorine sodium of 2 first 4 or the chlorine of 2 first 4 different two kinds of pharmacy mix of monooctyl ester when it is miscellaneous to target The theoretical value of careless fresh weight inhibition.

E is miscellaneous to target when being promazine Sulfometuron Methyl and the chlorine sodium of 2 first 4 or the different two kinds of pharmacy mix of monooctyl ester of the chlorine of 2 first 4 The measured value of careless fresh weight inhibition.

If the actual control of weeds rate (E) observed in biologic test exceedes uses Colby ' s methods Calculated desired value (E₀), then it represents that the effect of Herbicidal combinations is more than the summation of each agent effectiveness, this Mean that compositionss have potentiation.
