Weed management remains a critical challenge in modern agriculture, necessitating innovative approaches to enhance the efficacy of herbicides. Nanotechnology offers a promising avenue for the synthesis of herbicides with improved performance and reduced environmental impact. This study underscores the importance of employing nanotechnological methods in the synthesis of herbicides, emphasizing their potential to revolutionize weed management practices. The nano-encapsulated pretilachlor materials were synthesized using solvent evaporation method at the Centre for Agricultural Nanotechnology, Coimbatore (Tamil Nadu, India). This research explores the synthesis and characterization of nano-encapsulated pretilachlor utilizing the solvent evaporation method. Through transmission electron microscope (TEM), X-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and gas chromatography-mass spectrometry (GC-MS) analyses, we investigated the presence of nanoparticles, crystal structure, functional group, thermal stability, and composition of the nano-encapsulated pretilachlor herbicide. According to the results of characterization techniques on encapsulated pretilachlor, the TEM analysis confirmed the presence of pretilachlor, XRD analysis confirmed the nano-encapsulated pretilachlor exhibits amorphous nature and the polymer peak showed semi crystalline nature, FTIR validated the functional group of pretilachlor, TGA showed that double stage decomposition with high stable temperature and GC-MS analysis of different compounds of nano-encapsulated pretilachlor were detected representing with 100% concentration
