“…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.

An ecological study was done on weed species in two secondary forests present in Nnamdi Azikiwe University, Awka Campus and Federal College of Education Umunze, Anambra State, Nigeria. Data was collected from the two study sites which were randomly divided for adequate coverage and proper representation. Species dominance, abundance and diversity of weed species were recorded. The result of the study showed that a total of 21 weed species were recorded in Plot 1 study area which is at Nnamdi Azikiwe University, Awka campus; Pennisetum purpureum had the highest species abundance in the study site, with a total frequency of 93 and Dominance index of 28.97. Pennisetum purpureum had a relative density of while Tridax procumbens was the second most abundant with a frequency of 40 and Dominance of 7.10. Rhynchospora corymbosa showed the least abundance with a frequency of 6. The result of Shannon Wiener index for weed species in Plot 1 study was 2.56 and this showed that there is high diversity of weed species in the study area. Meanwhile, the result of the study in Plot 2, which is at Federal College of Education, Umunze showed that a total of 18 weed species were recorded; Imperata cylindrica had the highest species abundance in the study site, with a total frequency of 87 and Dominance index of 27.43, while Cypertrus rotundus was the second most abundant with a frequency of 67 and Dominance index of 10.5. Acanthus Montana showed the least in abundance with a frequency of 6 and Dominance index of 1.02. The result of Shannon Wiener index for weed species in Plot 2 study was 2.47 and this also showed that there is high diversity of weed species in the study area. This result invariably indicates a great potential for utilization in conservation and ecological purposes.

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.
