“…When metalaxyl‐M was applied with MAN + BOS + KRE (Mix 8), there was a statistically significant difference between the concentration of metalaxyl‐M on day 14 (PHI) and that of metalaxyl‐M applied alone (Table 3). Previous studies on the dissipation of metalaxyl‐M found that the half‐life of metalaxyl‐M was 5.3 and 6.0 days for sites 1 and 2, respectively, in Swiss chard in Korea, 35 and 2.4 days in parsley in Iran 36 …”

BACKGROUND: Grape and leaf quality are often severely reduced by fungi such as grey rot Botrytis cinerea Pers., powdery mildew Erysiphe necator Schwein, and downy mildew Plasmopara viticola (Berk. & M.A.Curtis) Berl. & De Toni and by insects such as Otiorhynchus spp., European grapevine moth Lobesia botrana Den.-Schiff., vine mealybug Planococcus citri Risso, and grape erineum mite Colomerus vitis Pgst. Various pesticides are often applied to mitigate these pest problems. These chemicals used singly as well as in the form of a mixture can leave residues on or in the crop. It is therefore of great importance to study the dissipation of the pesticides applied alone and in mixtures to this crop to protect consumers. RESULTS:The dissipation kinetics of cypermethrin, boscalid, deltamethrin, kresoxim-methyl, lambda-cyhalothrin, metalaxyl-M, metrafenone, and triadimenol residues were studied in vine leaves grown under sunny conditions in Turkey. The dissipation rate for singly applied pesticides followed first-order kinetics, with half-lifes in grape leaves in the range of 1.85-7.22 days. Changes in the degradation process of pesticide residues were determined after application, as both single applications and mixtures. The degradation of boscalid, cymoxanil, deltamethrin and metalaxyl-M accelerated while the degradation of cypermethrin, kresoxim-methyl, and lambda-cyhalothrin slowed down in mixtures of pesticides.CONCLUSION: The use of pesticides in mixtures leads to slower degradation and higher residues for some active ingredients and faster degradation and fewer residues for other active ingredients. Therefore, pesticide mixtures should not be applied in the field without having detailed information about their ingredients.

“…On the other hand, nature of the end products of natural degradation is distrustful because toxicity of the pesticide may be increased or decreased upon conversion to another compound (Menzie, 1972;Gavrilescu, 2005). As well, the persistence of pesticide residuals is also unrevealed because pesticide residuals are found in different matrices in the environment in different forms (Darko et al, 2008;Nag and Raikwar, 2011;Silva et al, 2019;Heshmati et al, 2020). The intensive and indiscriminate usage of pesticides has resulted in serious health issues both in human and other life forms, as well as there exist adverse side effects to the environment (Jeyaratnam, 1985;Kumar et al, 2013b;Sharma and Singhvi, 2017).…”

Purpose: Scientists have identified a plenty of bacterial strains having ability to degrade pesticide residues accumulated in the environment. Due to wide variation of chemical properties of pesticides, a single strain may not be versatile. Hence, identification of bioremediation ability of various bacteria is important. This review focused on understanding and explaining the role of soil bacteria having pesticide detoxification ability.Methodology: Previous research articles, book chapters and literature on bioremediation ability of different soil bacteria were reviewed and various strains of soil bacteria having bioremediation ability, mechanisms behind microbial bioremediation, factors affecting bioremediation and limitations and recent advancements of bioremediation were identified. Based on identified research gaps, further perspectives were introduced. Findings:The results revealed that plenty of soil bacteria having a bioremediation potential have been identified worldwide. As the major mechanism of bioremediation, the microorganisms consume pesticidecontaminated in the soil as their energy or nutrient sources. Various factors such as Bioavailability, Substrate and Environmental factors effect on bioremediation potential. Biostimulation, Bioaugmentation, Biopiling, Composting, Bioreactors and Land farming are identified as popular bioremediation methods suiTable 0for the bioremediation of pesticide contaminants. However, this technique still remains partially developed due to the lack of versatile microorganisms for detoxifying variety of different pesticides.

“…Since these products are consumed daily as food, the occurrence of pesticide residues can pose potential risks to the consumers' health and increase the chance of various chronic diseases and cancers (Mrema et al 2013;Hassani et al 2015;Guo et al 2016;Georgiadis et al 2018;Heshmati et al 2021). Thus, monitoring pesticide residues in agricultural products and food and performing risk assessments based on the residue data by evaluating parameters such as estimated daily intake (EDI) and hazard quotient (HQ) are crucial and have received considerable attention recently (Moretto et al 2015;Tsatsakis et al 2017;Dong et al 2017;Dong et al 2018;Bopp et al 2018;Pico et al 2018;Heshmati et al 2020aHeshmati et al , 2020b.…”

Pistachio is an economically valuable crop, and Iran is among the biggest producers, exporters, and consumers of this product in the world. During the growing season, pistachios are subjected to multiple sprayings with various pesticides, which result in the accumulation of their residues in nuts. These residues have raised concerns regarding consumers' health. In this research, uptake and dissipation kinetics of insecticides imidacloprid (IMI), thiacloprid (THI), thiamethoxam (THX), and abamectin (ABA) were investigated in pistachio nuts. Field experiments were conducted in a pistachio orchard. Pistachio trees were sprayed with the recommended dose of each insecticide formulation and water as the control. Samplings were performed for up to 49 days. Based on the results, pesticides uptake and dissipation kinetics were best fitted to first-order exponential growth (FOEG) and single firstorder kinetic (SFOK) models, respectively. Variations in pesticides uptake/dissipation rates were mostly related to their water solubility, pK a , and log K ow . THX showed a higher uptake rate (0.16 ± 0.04) compared to IMI (0.10 ± 0.01) and THI (0.06 ± 0.01). The fastest dissipation rates were observed for IMI (0.04 ± 0.002 day −1 ) and THX (0.03 ± 0.001 day −1 ), while the slowest belonged to THI (0.02 ± 0.003 day −1 ). ABA residues were below the quantification limit (LOQ) throughout the experiment. Based on FOEG and SFOK model predictions, multiple sprayings with THI and THX resulted in final concentrations exceeding the maximum residue limit (MRL). Hazard quotients for all pesticides were <1, indicating no risk to humans via consumption of the pistachio nut.
