| description | Owing to their small size, morphology and release modification properties, nanopesticides are considered promising alternative strategies for enhancing biological activity and minimizing pesticide losses. In this study, we used a colloidal self-assembly method to develop a morphology-stable, regularly rod-shaped nanoselenium pesticide carrier (NSer), which was further modified with chitosan. After loading penthiopyrad (PEN), the biological activity of NSer@PEN and its impact on the physiological and biochemical processes of plants were further compared with those of spherical nanoselenium pesticides (NSes@PEN) and commercial materials (20 % PEN SC). The biological activities were quantified through the EC50 values, which revealed that NSer@PEN (0.71 mg/L) and NSes@PEN (1.09 mg/L) exhibited significantly greater activity against Colletotrichum orbiculare Arx compared to 20 % PEN SC (2.70 mg/L). Moreover, through further investigation into the impact of nanopesticides on plant root exudates, Fourier transform infrared spectroscopy (FTIR) and two-dimensional correlation spectroscopy (2D-COS) analysis revealed that the ketone CO bond exhibited the strongest binding affinity, and the CO bond of phenols contributed significantly to the binding of cucumber root exudates induced by NSer@PEN, resulting in a mild response of the plant. The morphology-dependent nanoselenium carriers developed in this work are expected to enhance biological activity and reduce plant stress caused by pesticides, tackling one of the application challenges of pesticides. |
