Pesticides
will be used for a long period of time, and their use
may cause environmental contamination and adverse effects on human
health. The aim of this study was to improve the utilization rate
of pesticides and reduce the risk to the environment using mesoporous
silica nanoparticles (MSNs) as carriers. Compared to the conventional
formulation, spirotetramat-loading MSNs improved deposition, uptake,
and translocation performance in cucumber plants. MSNs may hold spirotetramat
in their mesoporous structure and prevent its degradation in plants.
The final residue of spirotetramat and its metabolites demonstrated
that spirotetramat-loading MSNs had low risk to the edible parts of
plants under foliar application. This study added our knowledge of
MSNs controlling pesticide release and transfer in plant.
