A family of fifteen quaternary ammonium salts (QAs), bearing the 1,2-bis(4-pyridyl)ethane core, were obtained using for the first time two different green methods, such as microwave (MW) and ultrasounds (US) irradiation, with very good yields and in much shorter times compared to the classical method, and an assay on their antimicrobial action against Escherichia coli (E. coli) was carried out. While 12 to 24 hours were required for complete alkylation of 1,2-bis(4-pyridyl)ethane by reactive halogenated derivatives in anhydrous solvent under reflux conditions, MW and US irradiation reduced the reaction time and the desired products were achieved in a few min. One of the aims of this study was to evaluate the antibacterial potential of the synthesized QAs against pathogenic bacteria, along with their impact on germination activity of wheat seeds (Triticum aestivum L.). The antibacterial activity of the QAs against Escherichia coli was explored by determining the minimum inhibitory concentration (MIC). The MIC values varied from 0.312 to 2.5 mg/mL, highlighting the lowest values attained for the derivatives containing methoxy, chlorine and benzofurane functional groups. The viability of aerobic bacteria was determined with the Tetrazolium/Formazan Test, a method that was found to be the best alternative approach with respect to the difuzimetric method. Seeds of Triticum aestivum L. were used for the evaluation of the germination indicators, such as seed germination (SG), the relative seed germination (RSG), the relative radicle growth (RRG), and the seed germination index (GI). The toxicity studies of QAs 1, 4 and 7, at two different concentrations, showed no inhibitory effect on seed germination.

Effectiveness of fungicide treatments during vegetation is recognized as important conditioning factor for the health of wheat crops. Furthermore, quantity and quality of the harvested grain are fundamentally affected by the health state of the crop during vegetation. Aim of this research was to identify the influence exercised by a gradient of fungicide treatments applied to wheat crop on seed mycosis susceptibility after harvest. Seeds belonging to three wheat cultivars (‘Andrada’, ‘Codru’, ‘Exotic’) that received a number of 0-3 fungicide treatments with some commonly used commercial products during vegetation (Credo, Evolus, Acanto Plus), were screened for germination rate, Alternaria sp. and Fusarium sp. incidence. Overall seed germination frequency was 96%, Alternaria sp. frequency was 8.78% and Fusarium sp. frequency was 2.25%. Seeds from the crop that received three fungicide treatments during vegetation displayed 5.38% higher seed germination relative to control, decrease of Alternaria sp. frequency of 60.94% and decrease of Fusarium sp. frequency of 57.10% relative to control. Results suggest a decrease of seed mycotic load associated with increased number of fungicide treatments applied on the crop. Optimization of fungicide application might be possible by studying the influence of phenophase on the effectiveness of the treatments, and these aspects shall receive more attention in the future.
