“…Liu et al [35] labeled pyraoxystrobin with radioisotope 14 C; the radiation intensity of various parts of plants can be observed using autoradiography, and then the distribution and route of pesticides in plants can be judged, but the method is costly and radioactive. Guglielmi et al [42] used a non-destructive method to study the absorption and conduction of pesticides in plants, which would allow monitoring over a much longer period without degrading the plants, and the data are more reliable. In this study, the fluorescence labeling method was used to study the conduction process of nanoparticles in plants.…”

Mesoporous silica nanoparticles (MSN) are widely used as pesticide carriers to enhance their effective utilization, since it can promote the solubility and absorption of pesticides by plants. For plants, the particle size of pesticides influences their absorption and efficacy. Herein, is our research work of the size effect of MSN on the loading, release, and delivery behavior of pyraoxystrobin (Pyr) in cucumber plants. The well-ordered Pyr-loaded carbon quantum dots-MSN (Pyr@M) with sizes of 15, 100, and 200 nm were prepared. A comparative study among different particle sizes of Pyr@M was carried out on the aspects of control release performance, loading content, uptake, and transportation performance in cucumber plants. It was found that the loading content increased as the particle size increased. The nanoparticles as carriers increased the solubility of insoluble Pyr, but the nanoparticle size had no clear difference impact on the release rate. The efficiency of the cellular uptake strongly depended on the particle size. The smaller the MSN size, the easier it was to be absorbed and transmitted by cucumber plants. Compared to the free Pyr, the upward transportation rate of Pyr from Pyr@M in plant increased by 3.5 times. These findings provide new theoretical basis to design the MSN pesticide delivery system.

A non‐destructive method for testing two components of the behaviour of soil‐applied agricultural chemicals over a long period

Abstract: This method must contribute to a better knowledge of the behaviour of commercial soil-applied phytochemicals. It can also be used to screen new xenobiotics within strategies to satisfy environmental requirements.
