Carbon nanotechnology is a growing research field with applications in electronics, medicine, and engineering. The application of carbon nanomaterials in agriculture has also been explored because of population growth and resource depletion. In this research, fungicide pyraclostrobin (Pyr) was successfully loaded on multiwalled carbon nanotubes (MWCNTs) via a physisorption process, with drug loading up to 16.64% (w/w). Compared with the 97% Pyr technical concentrate (97% Pyr TC), prepared Pyr-loaded MWCNTs had a longer period of sustained relea...
