“…ACE and IMI were the most common NEOs in pesticide residues detected in Hainan Province adjacent to the South China Sea. 39 This finding may be due to their similar concentration use structures in agriculture; therefore, ACE and IMI showed a good positive correlation in seawater. Furthermore, studies have shown that CLO is one of the metabolites of THM.…”

This study investigated the residual levels of eight parent neonicotinoid insecticides (p-NEOs) and three NEO metabolites (m-NEOs) in surface waters of river−estuary−ocean systems on a large geographical scale in South China. Imidacloprid, thiamethoxam, acetamiprid, and clothianidin were dominant NEOs in surface waters. High levels of ∑NEOs were found in the upper reaches of Guangzhou section of the Pearl River (PR_GZ), indicating multiple input sources of NEOs in PR_GZ. Additionally, the decreased influence of terrestrial input and human activities was observed along with the flow direction, where the order of ∑NEOs concentration was PR_GZ (inland river, 64.5 ng/L) > Pearl River Estuary (estuary, 33.9 ng/L) > Xisha Islands of the South China Sea (SS_XS, open sea area, 27.0 ng/L); and the level in Northwestern South China Sea (coastal sea, 49.9 ng/L) was also higher than that in open sea area. The estimated annual fluxes of NEOs released into the South China Sea totaled 34.8 ± 20.4 tons, most of which come from the Pearl River basin. To the best of our knowledge, this is the first study to assess the concentrations, distribution, and source analysis of NEOs in river−estuary−ocean systems in South China.

“…However, toxicological studies from vitro to vivo demonstrated that pesticides targeting different systems (such as nervous system, endocrine, reproduction, etc.) pose a persistent threat to non-target organisms in many aspects after long-term accumulation [ 44 ]. Results from epidemiology research, reappearance in model animals (e.g., zebrafish, rats, mice), and multi-omics data analysis demonstrated how pesticide residue affects each physiological system.…”

“…Additionally, it is necessary to ascertain the distribution of pesticides in maize plants before application in order to ensure food safety in field production. 26,27 In this study, EB granules were prepared by the rotating granulation method, and the granules were characterized using a Fourier transform infrared (FTIR) spectrometer. The disintegration process of the granules in water and in vitro release were studied.…”

Distribution of Emamectin Benzoate Granules in Maize Plants by Broadcasting into Maize Leaf Whorls

et al. 2023

Good control effects on fall armyworm (FAW) can be obtained by broadcasting emamectin benzoate (EB) granules into maize leaf whorls. However, the distribution of EB in maize plants is not clear. In this study, EB granules were prepared by the rotating granulation method, and the granules were characterized using a Fourier transform infrared spectrometer. The behavior of EB granules in water was observed using a microscope, and in vitro release of EB from granules was also studied. A method for the determination of EB in maize plants, old leaves, grains, and cobs was established by using ultra-performance liquid chromatography-tandem mass spectrometry. The results showed that EB was loaded in granules successfully, and the granules disintegrated slowly in water, so the release of granules could be regulated using various water contents. The prepared EB granules were qualified and stable. The field experiment showed that the concentration of EB in maize leaf whorls could be maintained above 0.23 mg·kg–1 within 3 days after broadcasting EB granules. This ensured that FAW could be killed in a short time. Then, EB gradually transferred to the old leaves. After 21 days of application, the content of EB in the old leaves was 0.07 mg·kg–1, which has long-time control effects on FAW. The control effects of the three doses of granules against Spodoptera frugiperda were higher than 78% after 14 days of application. At the tested dosage, no phytotoxicity to crops was observed. At harvest, neither the maize grain nor the cobs had EB content. New controlled formulations to S. frugiperda were developed and will be suitable for application in mountainous areas where the lack of water resources is a factor.
