Summary: This study developed a method for accurate analysis of dimethomorph and evaluated its uptake, dissipation, and residues in potato through foliar spray. The results showed that dimethomorph was translocated to the tubers within a few days and had relatively short half-lives in potato leaves, tubers, and soil. The risk assessment indicated that the recommended minimum dosages of dimethomorph posed little risk for consumption of potato tubers.

Summary: A method was developed to detect the residues of fluopimomide and dimethomorph in taro, showing rapid dissipation of both compounds and residues below the limit of quantitation within 14 days post-application. Dietary risk assessments indicate negligible long-term risks of the fluopimomide/dimethomorph mixed formulation in taro at recommended dosages.

Summary: This study evaluated the deposition and persistence of pyridaben in cotton fields, as well as its control effect on mites. Pyridaben dissipated faster in cotton leaves from Xinjiang and Shandong compared to soil, with slight variations between formulations. The initial deposition did not affect the complete degradation of pyridaben. The control effect on cotton mites was up to 80% at 14 days after application, indicating the rational use of pyridaben for crop protection and environmental safety.

Summary: A method for detecting pymetrozine residues in tea was established, showing that levels decreased during tea processing and were below MRLs in both China and EU in green tea collected at 6 and 21 days. Leaching rates of pymetrozine from dry tea to tea brew were also determined.

Summary: This study investigated the residue analysis, dissipation kinetics, and food safety evaluations of Hexaconazole in green chilli and soil. The results showed that Hexaconazole had a short half-life in green chilli, and washing with boiling water was an effective decontamination strategy to remove the residue.

Summary: This study found that crop residue inputs can increase soil organic carbon, nitrogen, and phosphorus contents, helping to alleviate soil carbon limitation and maintain balanced soil stoichiometry. The increase in soil organic carbon and carbon-to-nitrogen (phosphorus) ratio reached saturation after around 13-16 years, while the increase in grain yield stopped. A predictive model was proposed to evaluate the potential for crop residue improvement under different soil conditions and nitrogen input levels.

Summary: A modified-QuEChERS method was developed and validated for the determination of kresoxim-methyl in banana and soil using HPLC-MS/MS. The dissipation behavior, residue distribution, and risk assessment of kresoxim-methyl in banana were investigated. The results showed a low dietary risk of kresoxim-methyl in banana to humans, indicating the importance of proper and scientific usage of this formulation.

Summary: The study determines the persistence of herbicides in Indian soil and their impact on soil biological properties. The degradation of butachlor was faster in autumn rice soil than in winter rice soil, while the degradation of pretilachlor was similar in both seasons. No pesticide residue was detected in rice at harvest. The application of herbicides resulted in a decline in microbial biomass, microbial populations, and phosphatase activity, but increased dehydrogenase and urease activities in rice soil. The study suggests that the use of butachlor and pretilachlor at recommended rates does not negatively affect harvested rice or the soil environment.

Summary: The study validated a method to analyze kresoxim-methyl residue in green chilli, assessing its dissipation rate and safety evaluations. The residues in green chilli were found to be below the MRL after 2.33 days, with half-lives of 6.3 and 5.3 days for recommended dose and double dose, respectively.

Summary: The study investigates pesticide levels in celery and how they degrade after being sprayed with selenium nanoparticles. Results show that the degradation rate of pesticides in celery is accelerated, with reduced half-lives, and dietary exposure risk remains within acceptable limits, except for abamectin.

Summary: Oxygenic photosynthetic organisms have evolved mechanisms, such as the cysteine-mediated excitation quenching mechanism of IsiA protein, to dissipate excess light energy and provide photoprotection under stress conditions, ensuring optimal photosynthetic productivity and minimizing photodamage to cells.
