BACKGROUND: During the winter, the use of deicers wasrapidly increased for reduction of traffic accidents as well asinjuries in Korea, whose components are largely comprisedof calcium chloride and sodium chloride. Recently, toreduce the adverse effects of chloride-deciers such aspollution of water and soil, and decrease of agriculturalproductivity, the attention of eco-friendly deciers have beenincreased. This study aimed to investigate biological effectsof magnesium chloride deicer (PC-10) and organic aciddeicer (EFD-1) against wheat, barley, and spinach. METHODS AND RESULTS: We examined the effect oftwo deciers, PC-10 and EFD-1 on the seed germination andgrowth of wheat, barley and spinach. EFD-1 showed highersuppression of the germination than PC-10 among testedcrop seeds. In demage index of the seedlings of the crops,there was no symptoms in spinach such as spotting andcolor change of leaves. EFD-1 showed much strongerinhibitory effect on the germination of tested crop seedsthan PC-10 when crops were exposed continuously to testeddeciers in soils. The growth and shoot and root in examinedcrops was relatively higher in PC-10 treatment than inEFD-1 treatment when compared to the control. Thebiomass decrease was found in all examined conditions ofdeciers. PC-10 showed 23-35% reduction of biomasswhereas EFD-1 exhibited 39-84% loss in all examinedcrops at over 2% concentration. CONCLUSION: These results suggest that the effects ofdeicers used in this study by inputting into soil againstgrowing tested crops cause the reduction of germination ofseeds, growth, and biomass compared to the control.
