“…Volatilization and drift of agricultural run-off allows the commercial herbicidal formulations to spread in the environment and cause unintended contaminations. This provided the opportunity to produce novel, effective formulations based on currently manufactured herbicides, such as halogenated derivatives of phenoxyacetic acid (2,4-D, MCPA and MCPP) [5][6][7][8] or benzoic acid (Dicamba), 9 fomesafen, 10 glyphosate 11 and sulfonylurea (metsulfuron methyl). The commercial formulations of herbicides also contain various additives, which improve their biological activity.…”

Novel herbicidal ionic liquids (HILs) containing different anions and cations derived from ammonium esterquats were prepared by employing a simple, inexpensive pathway. The basic physicochemical properties of the synthesized salts (such as density, viscosity, refractive index, solubility and thermal stability) were determined.Additionally, their herbicidal efficacy was evaluated under greenhouse and field conditions with a subsequent assessment of biodegradability and toxicity (acute oral toxicity towards rats and rainbow trout, the growth inhibition test of green algae and the acute immobilization test using water flea). The results of greenhouse and field experiments revealed that the herbicidal activity of HILs comprising long alkyl chains has exceeded that of commercial plant protection products. The HIL containing the di(tallowoyloxyethyl)dimethylammonium cation exhibited notable biodegradability (63% after 28 days) and various toxicity classifications depending on the tested organism: category V towards rats with LC 50 4 2000 mg, category II towards fish with LC 50 /96 h at 10.62 mg L À1 , category I towards algae and daphnids with E r C 50 /72 h at 1.73 mg L À1 and EC 50 at 0.28 mg L À1 , respectively. These findings provide evidence that the synthesis of HILs with a specifically designed structure may be successfully employed for obtaining novel, efficient and environmentally friendly plant protection agents. † Electronic supplementary information (ESI) available: 1 H and 13 C NMR spectra, detailed testing procedures for: the acute toxicity test towards rats, the acute oral toxicity test towards rainbow trout, the growth inhibition test of green algae, the acute immobilization test using water flea.

“…The literature describes combinations of ammonia and phosphonium cations containing anions of phenoxyacetate [14][15][16], dicamba [17], and fomesafen [18], confirming that they maintain their biological activity, which tends to be higher than that of the currently popular commercial preparations. Herbicidal ionic liquids are also characterized by lower mobility in the soil and groundwater.…”

Herbicidal ionic liquids exhibit many advantages compared to conventional chemical plant protection agents, which allow for a reduction of the herbicide dose per hectare and decrease of toxicity. Popular herbicides, such as 4-chloro-2-methylphenoxyacetic (MCPA) or 2,4-dichlorophenoxyacetic (2,4-D) acids, can be modified by reaction with long chain ammonium cations in order to obtain novel forms. The aim of this study was to present an alternative method for the synthesis of herbicidal ionic liquids based on a natural cation known as Ethoquad C/12 and to analyze the physicochemical properties and herbicidal activity of the obtained products. New ionic liquids comprising MCPA and 2,4-D as anions were obtained and their chemical as well as thermal stability were evaluated. Furthermore, their biological and surface activity were investigated. The obtained results confirmed that the herbicidal activity has been preserved.
