Detailed Description
The synergistic effect of the fungicidal, bacterial compositions according to the invention on harmful fungi and bacterial diseases can be illustrated by the following examples, to which the invention is in no way restricted.
The active compounds, alone or in combination, are prepared as acetone or DMSO stock solutions containing 0.25% by weight of active compound. 1% by weight of emulsifier
(wetting agents based on ethoxylated alkylphenols with emulsifying and dispersing action) are added to the stock solution and the active compound or mixture is diluted with water to the desired concentration in the examples below.
The expected potency of the active compound mixtures was determined using the Colby formula [ S.R.Colby.calcium synergy and antibiotic Responses of pharmaceutical compositions.Weeds, 1967,15(1):20-22] and compared with the observed potency.
Colby formula: e ═ x + y-xy/100
E: the expected efficacy when using mixtures of active compounds a and B at concentrations a and B, respectively, is expressed as% of the untreated control.
x efficacy when using active compound a at a concentration a, expressed as% of untreated control;
y efficacy when using active compound B at a concentration of B, expressed as% of the untreated control.
If the actual observed efficacy (O) is greater than the expected efficacy (E), the effect of the combination is a synergistic effect, which corresponds mathematically to a positive difference in (O-E). If the actual observed efficacy (O) is equal to the expected efficacy (E), the effect of the combination is a purely additive effect, showing no synergy, mathematically the difference corresponding to (O-E) is zero. If the actual observed potency (O) is less than the expected potency (E), then the effect of the combination is an antagonistic effect, mathematically the difference corresponding to (O-E) is negative.
