Both the pesticide residues in the soil and the presence of antifeedant on seeds (de Paulo may have a negative effect on plant germination and development. Therefore, the effect of quinine-based QASs and a reference substance (quinine hydrochloride) on seeds of a dicotyledonous (white mustard, S. alba) and a monocotyledonous plant (sorghum, S. bicolor) was studied at different concentrations. The effect of the application on the germination capacity of the plants is shown in Table .5 (Supplementary Data), while 3 at the earliest stage of white mustard and sorghum development. Also, no significant germination delays were observed during the experiment compared to the control.
