The GC-MS analysis was performed to determine the encapsulation efficiency and pesticide loading efficiency using a Shimadzu GC coupled with a GCMS-QP 2010 plus mass detector and a single-quadrupole mass spectrometer Quantum (Shimadzu) with 100% dimethyl polysiloxane (Restek Rxi-1ms; 30 m × 0.25 mmiD., 0.25 μm film thickness) column. GC-MS operating conditions: The initial oven temperature was 60 °C, maintained for 1 min and then ramped to 270 °C at a rate of 10 °C/min followed by holding for 5 min at 270 °C. The initial temperature of the injector was 63 °C and then programmed at the same rate as the oven.
