Summary: This research investigated the effectiveness of boron-containing products and plant-based surfactants in removing pesticide residues from tomatoes and apples. The results showed that both types of treatments were able to significantly reduce the pesticide residues, with the highest removal rate achieved using 1% etidot at 72%. The importance of cuticle thickness in pesticide removal was also highlighted. Overall, this research has practical implications for reducing pesticide residues on fruits and vegetables.

Summary: The persistence of the combination formulation of fluopyram 200 + tebuconazole 200-400 SC was evaluated for the management of fungal diseases in mango and pomegranate in India. The results showed that the fungicide degraded relatively quickly, but within the recommended pre-harvest interval, it did not pose a significant risk to public health.

Summary: The persistence of fluopyram and tebuconazole in different crops and agricultural soils has been studied. However, the behavior of these fungicides may change when they are applied as a combined formulation in organically amended vineyard soils under field conditions. This study evaluates the effect of applying spent mushroom substrate (SMS) or this residue re-composted with ophite (SMS + OF) on the adsorption, dissipation, and mobility of fluopyram and tebuconazole in vineyard soils. The results indicate different dissipation mechanisms for both fungicides, as the adsorption by soil organic carbon prevented the dissipation of fluopyram but facilitated the dissipation of tebuconazole, probably due to the formation of non-extractable residues.

Summary: Insecticides are important for increasing crop yields, but excessive use has negative impacts on the environment and human health. This study developed a simple and efficient analytical method using acetonitrile extraction and UPLC-MS/MS to determine the residues of spiromesifen and spirodiclofen in tomato fruit. The method was validated with good linearity, LOD, LOQ, and recovery rates. The dissipation behavior of the insecticides in tomato fruit under field conditions was also studied, showing that spiromesifen dissipated more rapidly than spirodiclofen. The final residue concentrations were below the European Union maximum limits and the insecticides were deemed safe for adult consumers based on chronic risk assessment.

Summary: Supervised field trials were conducted for two consecutive years to estimate the dissipation and persistence of indoxacarb and thiamethoxam residues in chili. The results showed that the half-life of indoxacarb in green chili was 3.46-4.77 and 3.58-3.76 days, while in soil it was 3.85 and 4.93 days, respectively, at single and double recommended doses. The residues of thiamethoxam in seedlings, green chili fruits, and red chili fruits were below the limit of quantification.

Summary: The dissipation kinetics of atrazine and trifluralin in clay loam soil were investigated under different temperature and moisture conditions. Temperature had a greater impact on atrazine persistence, while the interaction of temperature and moisture was significant for trifluralin over time. Both herbicides tended to double their half-life with every 10 degrees C decrease in temperature, indicating the potential for years of persistence in soil conditions <= 20 degrees C.

Summary: This study aims to establish consumer safety by studying the dissipation pattern and dietary risk assessment of fluopyram and tebuconazole in kidney beans. A simple QuEChERS analytical method was used to analyze the residues of these two fungicides in different plant parts and soil. The results showed that the dietary intake risk of fluopyram and tebuconazole from kidney beans is negligible.

Summary: A field dissipation study was conducted to evaluate the pre-harvest interval (PHI) and processing factor (PF) for fluopyram and tebuconazole residues in grapes and raisins. An analytical method using LC-MS/MS was established for the simultaneous extraction and analysis of these residues. The residues dissipated with specific half-lives and the residues during raisin preparation showed degradation. The established PHI and PF values ensure the management of these residues in grapes and raisins.

Summary: The study found that the degradation of fluopyram and tebuconazole was faster in the poly-house with lower light intensity, while the fungicides persisted longer in the open field. In bell pepper, fluopyram had the longest half-life in leaves and the shortest in soil, while tebuconazole exhibited faster dissipation in fruits.

Summary: Pesticide dissipation half-life in plants is crucial for assessing environmental fate of pesticides and establishing good agriculture practices. This study utilized machine learning models to predict the dissipation half-life and proposed novel intervals to account for variations in empirical data. The best-performing model, GBRT-ECFP, showed the potential of machine learning in evaluating pesticide fate in agricultural crops.

Summary: The dissipation kinetics and dietary risk assessment of spiromesifen were studied on four summer vegetables. The residues of spiromesifen dissipated rapidly after spraying on the fruits, with suggested safe waiting periods varying slightly among different crops. The hazard quotient was found to be below 1, and the theoretical maximum dietary intake was lower than the maximum residue limit in all vegetable crops investigated.
