Abstract: 

Background: One of the main reasons of environmental contaminations is the broad application of herbicides. Controlled release technologies such as encapsulation of herbicides are as an effective tool to reduce environmental contaminations. The aim of the present study was successful nanocapsulation of Gallant Super (GS), its characterization and compare the physiological responses of Spirodela polyrhiza L. upon exposure to GS and its encapsulated form.
Methods: Nanocapsulation of GS in the poly (methyl methacrylate) (PMMA) was performed in the Department of Nanotechnology, Faculty of Sciences and biological effects of the contaminants on S.
polyrhiza was investigated in Biotechnology Research Center, both in Urmia University, Urmia, Iran in 2016. The surface morphology of PMMA/GS nanocapsules was studied by SEM and TEM and their chemical characterization was determined by FT-IR spectroscopy. For assessment of the effects of the encapsulated Gallant Super (ECGS) and GS on S. polyrhiza, some plant physiological parameters were investigated.
Results: Direct treatment of GS had more and notable negative effects on the plant growth when compared with ECGS treatments. Moreover, different examined concentrations of the two contaminant groups led to the remarkable induction of the activities of the antioxidant enzymes such as SOD. Even though the enhancement of the antioxidant enzymes activities when the plant was treated with GS was notably more than the effects of ECGS.
Conclusion: ECGS caused to the fewer changes in the plant physiological parameters and negative effects of the treatment of ECGs were less than when the plant had direct contact with GS.
