“…An effective method of weed control is the use of chemical preparations in the form of herbicides . An extremely important aspect of the use of herbicides in plant production is the possibility that weeds will become resistant to plant protection agents. − One of the most common herbicides is dicamba, (3,6-dichloro-2-methoxy)benzoic acid, which was developed in the early 1960s as a selective herbicide for pre- and postemergence control of weeds in cereal crops. − After application, dicamba can translocate through all broadleaf weeds, causing their destruction . Herbicides based on dicamba have high vapor pressures (2.6 × 10 –8 atm at 25 °C), suggesting substantial volatility after application. ,, …”

A series of piperidinium-based herbicidal ionic liquids (HILs) were synthesized and investigated. The designed HILs, obtained with high yields, consisted of cation 1-alkyl-1-methylpiperidinium with surface activity and a commercially available herbicidal anion: (3,6-dichloro-2-methoxy)benzoates (dicamba). The above-mentioned compounds were characterized in terms of surface activity and phytotoxicity. Preliminary results were obtained at higher wettability for all HILs when compared to the wettability of commercial Dicash, with HIL having 18 atoms in the carbon chain being the best effectiveness in wetting surfaces (weeds and crop leaves), whereby a drop of HILs with short alkyl chains (C 8 −C 10 ) could not slide down a leaf. Our findings present that wettability or mobility of HILs drops varied depending on the plant species. Moreover, in this study, by zeta potential and atomic force microscopy measurements, we provide conclusive evidence to demonstrate that alkyl chain elongation plays a significant role in the evolution of surface properties of HILs.
