Abstract
BACKGROUND Fertilizers and pesticides are commonly used simultaneously in agriculture. However, the effects of common fertilizers on the dissipation, enantioselectivity, and metabolites of the chiral insecticide fipronil in soil are yet to be reported. RESULT An enantioselective method for detecting fipronil enantiomers and their metabolites in different soil matrices was developed using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The results showed that organic and compound fertilizers significantly decreased the degradation of S- and R-fipronil, whereas phosphate and microbial fertilizers slightly reduced fipronil dissipation. The half-life values for S- and R-fipronil were 43.3 and 28.9 days, 99.0 and 63.0 days, 69.3 and 43.3 days, 46.2 and 30.1 days, and 43.3 and 31.5 days, respectively, in the control and the four fertilizer treatments, respectively. The enantioselectivity of fipronil enantiomers occurred and R-fipronil exhibited preferential degradation with an enantiomeric fraction (EF) of 0.4900-0.6238 in all treatments; but the four tested fertilizers decreased enantioselectivity with EF values changed from 0.4970 to 0.6238 in the control to 0.4900-0.6171 in fertilizer treatments. Two metabolites, fipronil sulfone and sulfide, were produced, and their amounts increased with culture time in all treatments. Fertilization reduced the content of fipronil sulfide and sulfone but hardly reduced the total amount of fipronil and its metabolites. CONCLUSION Fertilizers affect the environmental behavior of fipronil in the soil. Fertilization alters the soil bacterial community, which may be an important factor. This influence is relatively complicated and should be comprehensively considered in the environmental risk assessment of pesticides. © 2023 Society of Chemical Industry.

CHEMOSPHERE 2020; 261:127762. [PMID: 32738715 DOI: 10.1016/j.chemosphere.2020.127762] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Revised: 07/07/2020] [Accepted: 07/15/2020] [Indexed: 06/11/2023]
Abstract
The presence of microplastics (MPs) and their effects have been widely investigated in the aquatic environment, whereas the research done in the terrestrial environment is incomparably lacking. MPs are considered a pollutant in soil on agricultural land, where they can act as a vector for other pollutants, namely organic chemical compounds, such as pesticides. In soil, presence of MPs is affecting the growth and life of microorganisms in it. The interactions between two types of MPs and three pesticides in the mixture with alluvial soil were studied. Adsorption of acetamiprid, chlorantraniliprole and flubendiamide in concentrations of 1, 5 and 10 mg L-1 onto polyester fibres and polypropylene particles of 0.5-1 mm size was studied at 1% and 5% (w/w) of their content in soil. Results showed that the adsorption of pesticides was dependent on their octanol/water partition coefficient, with the most highly adsorbed pesticide also being the most hydrophobic, regardless of the type and form of MPs. Adsorption of pesticides onto MP particles was confirmed in soil-MPs mixtures with 5% polypropylene and 5% polyester at all tested pesticides' concentrations, proving that MPs in soil systems act as carriers to pollutants. MPs in soil decreased the soil's intrinsic capacity to retain pesticides, indicating the possibility of a greater mobility of pesticides on MPs through the soil system.

Role of climate change variables (standing water and rainfall) on dissipation of chlorantraniliprole from a simulated rice ecosystem. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2020; 205:111324. [PMID: 32971453 DOI: 10.1016/j.ecoenv.2020.111324] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Revised: 08/10/2020] [Accepted: 09/10/2020] [Indexed: 05/27/2023]
Abstract
Chlorantraniliprole (CAP) is extensively used for rice pest management. Lack of information on the role of standing water and amount and timing of rainfall on CAP dissipation in rice ecosystem could hamper its prospective use. Present study was performed to investigate the effects of different water regimes (saturated, 5 and 10 cm standing water) and simulated rainfall (40 and 100 mm occurred at 4, 8 and 24 h after CAP application) on leaching, surface runoff and dissipation of CAP into components of rice ecosystem. The results showed highest concentration of CAP residues in soil and plant under saturated condition followed by 5 and 10 cm standing water conditions. Whereas, the highest concentration of CAP in leachates was detected under 10 cm standing water (12.19 ng mL-1). The results revealed large amount of leaching (21.99 ng mL-1) and surface runoff (42.25 ng mL-1) losses of CAP when 100 mm rainfall occurred at 4 h after pesticide application. The total quantity of CAP residues in soil and plant was highest when rainfall occurred at 24 h after pesticide application under both the rainfall amounts. Water stagnation and high intensity rainfall occurred shortly after pesticide application will contribute to pesticide loss to non-target sites through surface run-off and leaching. There will be less pesticide available in soil for plant uptake which may not be sufficient to kill the target organisms.

Abstract
Persistence and sorption behaviour of flubendiamide in two different Indian soils as affected by maize stalk biochar was studied. The persistence was more in West Bengal soil (178.6 days) than Sikkim soil (165.3 days) at 10 µg g-1 fortification level. Biochar amendment addition to soil at 5% enhanced the degradation process and half-life (T1/2) values were 103.5 and 117.4 days, respectively for biochar amended Sikkim and West Bengal soil. Sorption study through batch equilibrium method resulted the 4 h equilibrium time with adsorption 6.22% ± 0.16% and 5.26% ± 0.16% in Sikkim and West Bengal soil, respectively. Biochar addition at 5% increased the adsorption of flubendiamide to 8.12% ± 0.16% and 5.88% ± 0.16% indicating a greater influence in this process. The adsorption was more in biochar amended Sikkim soil than West Bengal soil. The values of desorption was slower than adsorption indicating a hysteresis effect having hysteresis coefficient (H1) ranges between 0.025 and 0.151 in two test soils.

Abstract
Atrazine and bifenthrin persistence study was carried out in three sludge amended soil under laboratory condition. Atrazine persisted shorter in sludge amended soil sludge-3 (half-life 23.4 days) followed by sludge-2 (half-life 30.1 days) and sludge-1 (half-life 37.1 days) than unamended control (half-life 150.5 days). Bifenthrin followed the similar pattern with sludge-3 (half-life 43.1 days) which increased to 50.3, 60.2 and 75.2 days, respectively in sludge-2, sludge-1 and unamended control representing an immense influence of sludges on degradation. Duncan's Multiple Range Test revealed that carbon mineralization process was significantly influenced by all the sludges (p < 0.0001). Sludge-3 indicated highest Cmin (initial 118.16 to final 133.64 mg CO2-C/kg) in bifenthrin and 129.91 mg CO2-C/kg in atrazine. The relatively high Cmin rate in sludge amended soil than unamended control suggested a lower persistency of both the pesticides and thus decreasing its potential ecological risk. Sludge-3 sludge amended soil increased the dehydrogenase enzyme activity as compared to sludge-1 and sludge-2 sludge in atrazine.

Abstract
Abstract
Purpose
Flubendiamide is a highly toxic and persistent insecticide that causes loss of insect muscle functions leading to paralysis and death. The objective was to screen for filamentous fungi in soils where insecticides had been applied, to isolate entomopathogenic fungi from insect larva (Anticarsia gemmatalis) that infest soybean crops, and to use these in biodegradation of insecticides.
Method
Filamentous fungi were isolated from soils, and growth inhibition was evaluated on solid medium containing commercial insecticides, Belt® (flubendiamide) and Actara® (thiamethoxam). A total of 133 fungi were isolated from soil and 80 entomopathogenic fungi from insect larva. Based on growth inhibition tests, ten soil fungi, 2 entomopathogenic fungi, and Botryosphaeria rhodina MAMB-05 (reference standard) were selected for growth on commercial insecticides in solid media. Fungi were grown in submerged fermentation on media containing commercial insecticides and assayed for laccase activity.
Result
Isolates JUSOLCL039 (soil), JUANT070 (insect), and MAMB-05 performed best, and were respectively inhibited by 48.41%, 75.97%, and 79.23% when cultivated on 35 g/L Actara®, and 0.0, 5.42%, and 43.39% on 39.04 g/L Belt®. JUSOLCL039 and JUANT070 were molecularly identified as Trichoderma koningiopsis and Neurospora sp., respectively. The three fungal isolates produced laccase constitutively, albeit at low activities. Fungal growth on pure flubendiamide and thiamethoxam resulted in only thiamethoxam inducing high laccase titers (10.16 U/mL) by JUANT070. Neurospora sp. and B. rhodina degraded flubendiamide by 27.4% and 9.5% in vivo, while a crude laccase from B. rhodina degraded flubendiamide by 20.2% in vitro.
Conclusion
This is the first report of fungi capable of degrading flubendiamide, which have applications in bioremediation.

Abstract
An enantioselective method of pyriproxyfen enantiomers in fertilized soil was established on Lux Cellulose-3 column using ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The effects of urea, potassium dihydrogen phosphate, organic fertilizer and compound fertilizer on the dissipation of pyriproxyfen in soil were investigated. Studies have shown that pyriproxyfen had a good linearity in the range of 0.050-7.5 μg/g. The method LODs and LOQs of two enantiomers were 0.0032-0.015 μg/g and 0.050 μg/g, respectively. The recoveries of two enantiomers ranged from 80.61% to 110.86%, intra-day together with inter-day RSDs of 1.38-12.52%. The results indicated that compound fertilizer could promote the dissipation of pyriproxyfen in soil, while the organic fertilizer, potassium dihydrogen phosphate and urea slowed down the dissipation of pyriproxyfen. Enantioselective dissipation of pyriproxyfen enantiomers occurred in blank soil and fertilized soil but performed not obviously. Pyriproxyfen almost not dissipated for 42 d when urea was added. These results revealed that the use of fertilizers would have impacts on the behaviors of this pesticide. The impacts were relatively complex which should be fully considered in future environmental risk evaluation.

Abstract
Clothianidin is a widely used insecticide under Indian subtropical condition. The objective of this study was to generate residue data which aims to understand leaching potential of clothianidin [(E)-1-(2-chloro-1,3-thiazol-5-ylmethyl)-3-methyl-2- nitroguanidine] through packed soil column. The maximum amount of clothianidin was recovered at 0-5 cm soil depth in both Manipur (67.15%) and Delhi soil (52.0%) under continuous flow condition. Manipur and Delhi soil concentrated maximum residue with or without farm yard manure (FYM) in 0-20 cm soil depth. The effect of varying the amount of water enhanced the distribution of residues in the first 0-5 cm layer. Among the tested soils, residue was detected in the leachate from Delhi soil (0.04 µg/mL). Clothianidin leaching was minimized in soil of Manipur compared to Delhi after incorporation of FYM. As the volume of water increased upto 160 mL, mobility increased and residues moved to lower depth. Clothianidin did not leach out of the 25 cm long soil columns even after percolating water equivalent to 415.42 mm rainfall. Clothianidin is mobile in soil system and mobility can be reduced by organic amendment application.

Abstract
This paper reports the use of solar heating techniques, solarization (S) and biosolarization (BS) as a strategy for the environmental restoration of soils containing neonicotinoid, acetamiprid (AC), imidacloprid (IM) and thiamethoxam (TH), and diamide, chlorantraniliprole (CL) and flubendiamide (FB) insecticide residues. For this, a semiarid Mediterranean soil (Haplic calcisol) was covered with low-density polyethylene (LDPE) during the hot season, to raise the maximal soil temperatures. Compost from sheep manure (CSM), meat-processing waste (MPW) and sugar beet vinasse (SBV) were used as organic wastes. The results showed that both S and BS increase insecticide disappearance rates compared with the non-disinfected soil, the increase in soil temperature and added organic matter playing a key role. The dissipation rates of TH and AC in soil were satisfactorily described by first-order (monophasic) kinetics, while IM, CL and FB showed a deviation from exponential behaviour. For them, the best results were obtained applying biphasic kinetics with a rapid initial degradation followed by a slower decline of their residues. The findings suggest that S and BS (especially using MPW) can be considered as a valuable tool for enhancing the detoxification of soils polluted with these insecticides.

Abstract
Pesticide persistence and degradation in soil are influenced by factors like soil characteristics, light, moisture etc. Persistence of tricyclazole was studied under different soil moisture regimes viz., dry, field capacity and submerged in two different soil types viz., Inceptisol and Ultisol from Delhi and Karnataka, respectively. Tricyclazole dissipated faster in submerged (t1/2 160.22-177.05d) followed by field capacity (t1/2 167.17-188.07d) and dry (t1/2 300.91-334.35d) in both the soil types. Half-life of tricyclazole in Delhi field capacity soil amended with Blue Green Algae (BGA), was 150.5d as compared to 167.1d in unamended soil. In Karnataka soil amended with BGA the half-lives were 177.0d compared to 188.0d in unamended soil, indicating that BGA amendment enhanced the rate of dissipation of in both the selected soils. Tricyclazole was found to be stable in water over a pH range of 3-9, the half life in paddy field was 60.20d and 5.47d in paddy soil and paddy water, respectively. Statistical analysis and Duncan's Multiple Range Test (DMRT) revealed significant effect of moisture regime, organic matter and atmospheric CO2 level on dissipation of tricyclazole from soil and pH of water (at 95% confidence level p<0.0001).

Abstract
An experiment was conducted under three levels of atmospheric CO2 [ambient (398 ± 10 μmol mol(-1)), elevated (570 ± 10 μmol mol(-1)) and open condition], three levels of temperature (4, 25, and 40 °C) to study the degradation pattern of flubendiamide in soil and also carbon mineralization in soil. Results of this study revealed that flubendiamide was found to persist longer under outdoor condition (T1/2, 177.0 and 181.1 days) than ambient (T1/2, 168.4 and 172.3 days) and elevated condition (T1/2, 159.3 and 155.3 days) at 1 and 10 μg g(-1) fortification level, respectively. Results also revealed that flubendiamide dissipated faster at 40 °C (T1/2, 189.4 days) than 25 °C (T1/2, 225.3 days). Slower dissipation was recorded at 4 °C (T1/2, 326.3 days). Thus, increased CO2 levels and temperature following global warming might adversely affect flubendiamide degradation in soil. Laboratory study on microbial biomass carbon (MBC) and carbon mineralization (Cmin) in soil revealed that in des-iodo flubendiamide-treated soils, MBC significantly increased up to 45 days and then decreased. Flubendiamide-treated soil showed a non-significantly decreasing trend of soil MBC with time up to the 15th day of incubation and after 15 days significantly decreased up to 90 days of incubation. In des-iodo flubendiamide-treated soil, the evolution of CO2 decreased up to 45 days, which was increased after 45 days up to 90 days. In flubendiamide-treated soil, CO2 evolution decreased up to 30 days and after 45 days, it increased up to 90 days.

Abstract
The effect of abiotic factors on dissipation of spinosad (soil moisture regimes, pH, and light) was studied. Spinosad residues were estimated using high performance liquid chromatography fitted with a UV detector. Under laboratory conditions, half-lives of spinosad were 9.0 and 7.7 days for air dried and field capacity soils, respectively. Percent dissipation of spinosad after 30 days was 47.02, 22.35, 62.5, 68.23 and 76.47 in solution with an aqueous pH of 10.85, 9.15, 6.97, 3.90 and 2.04, respectively. The half-life of spinosad in UV and sunlight was only 1.6 and 5.2 h, respectively. Light, especially the UV component, is an important factor for degradation of spinosad compared to other abiotic conditions.

Abstract
This investigation was undertaken to compare the dissipation pattern of flubendiamide in capsicum fruits under poly-house and open field after giving spray applications at the recommended and double doses of 48 g a.i. ha(-1) and 96 g a.i. ha(-1). Extraction and purification of capsicum fruit samples were carried out by the QuEChERS method. Residues of flubendiamide and its metabolite, des-iodo flubendiamide, were analyzed by high-performance liquid chromatography-photodiode array, and confirmed by liquid chromatography-mass spectrometry/mass spectrometry. Limit of quantification of the method was 0.05 mg kg(-1), and recovery of the insecticides was in the range of 89.6-104.3%, with relative standard deviation being 4.5-11.5%. The measurement uncertainty of the analytical method was in the range of 10.7-15.7%. Initial residue deposits of flubendiamide on capsicum fruits grown under poly-house conditions were (0.977 and 1.834 mg kg(-1)) higher than that grown in the field (0.665 and 1.545 mg kg(-1)). Flubendiamide residues persisted for 15 days in field-grown and for 25 days in poly-house-grown capsicum fruits. The residues were degraded with the half-lives of 4.3-4.7 and 5.6-6.6 days in field and poly-house respectively. Des-iodo flubendiamide was not detected in capsicum fruits or soil. The residues of flubendiamide degraded to below the maximum residue limit notified by Codex Alimentarius Commission (FAO/WHO) after 1 and 6 days in open field, and 3 and 10 days in poly-house. The results of the study indicated that flubendiamide applied to capsicum under controlled environmental conditions required longer pre-harvest interval to allow its residues to dissipate to the safe level.

Das SK, Mukherjee I, Kumar A. Effect of soil type and organic manure on adsorption-desorption of flubendiamide. ENVIRONMENTAL MONITORING AND ASSESSMENT 2015; 187:403.

Abstract
Laboratory study on adsorption-desorption of flubendiamide was conducted in two soil types, varying in their physical and chemical properties, by batch equilibrium method. After 4 h of equilibrium time, adsorption of flubendiamide on soil matrix exhibited moderately low rate of accumulation with 4.52 ± 0.21% in red soil and low rate with 3.55 ± 0.21% in black soil. After amending soils with organic manure, adsorption percentage increased to 6.42 ± 0.21% in red soil and (4.18 ± 0.21%) in black soil indicating that amendment significantly increased sorption. Variation in sorption affinities of the soils as indicated by distribution coefficient (K d) for sorption was in the range of 2.98-4.32, 4.91-6.64, 1.04-1.45 and 1.92-2.81 ml/g for red soil, organic manure-treated red soil, black soil and organic manure-treated black soil, respectively. Desorption was slightly slower than adsorption indicating a hysteresis effect having hysteresis coefficient ranges between 0.023 and 0.149 in two test soils. The adsorption data for the insecticide fitted well the Freundlich equation. Results revealed that adsorption-desorption was influenced by soil types and showed that the maximum sorption and minimum desorption of the insecticide was observed in soils with higher organic carbon and clay content. It can be inferred that crystal lattice of the clay soil plays a significant role in flubendiamide adsorption and desorption. Adsorption was lower at acidic pH and gradually increased towards alkaline pH. As this insecticide is poorly sorbed in the two Indian soil types, there may be a possibility of their leaching to lower soil profiles.

Abstract
Persistence of spiromesifen in soil as affected by varying moisture, light, compost amendment, soil sterilization and pH in aqueous medium were studied. Degradation of spiromesifen in soil followed the first-order reaction kinetics. Effect of different moisture regimes indicated that spiromesifen dissipated faster in submerged soil (t 1/2 14.3-16.7 days) followed by field capacity (t 1/2 18.7-20.0 days), and dry soil (t 1/2 21.9-22.9 days). Dissipation was faster in sterilized submerged (t 1/2 17.7 days) than in sterilized dry (t 1/2 35.8 days). Photo spiromesifen metabolite was not detected under different moisture regimes. After 30 days, enol spiromesifen metabolite was detected under submerged condition and was below detectable limit (<0.001 μg g(-1)) after 90 days. Soil amendment compost (2.5 %) at field capacity enhanced dissipation of the insecticide, and half-life value was 14.3 against 22.4 days without compost amendment. Under different pH condition, residues persisted in water with half-life values 5.7 to 12.5 days. Dissipation in water was faster at pH 9.0 (t 1/2 5.7 days), followed by pH 4.0 (t 1/2 9.7 days) and pH 7.2 (t 1/2 12.5 days). Exposure of spiromesifen to different light conditions indicated that it was more prone to degradation under UV light (t 1/2 3-4 days) than sunlight exposure (t 1/2 5.2-8.1 days). Under sunlight exposure, photo spiromesifen metabolite was detected after 10 and 15 days as compared to 3 and 5 days under UV light exposure.

Abstract
The dissipation of pyraclostrobin, a strobilurin fungicide, in soil was found to be influenced by soil moisture, organic matter content and microbial population. Among the different moisture regimes, dissipation was faster under submerged condition (T1/2 10 days) followed by field capacity (T1/2 28.7 days) and in dry soil (T1/2 41.8 days). Use of sludge at 5 % level to Inceptisol favoured a faster dissipation of pyraclostrobin, whereas a slower rate of dissipation was observed in partial organic matter removed soil as compared to normal soil. Slower rate of dissipation was also observed in sterile soil (T1/2 47 days) compared to normal soil. Pyraclostrobin dissipated faster in Vertisol (T1/2 21.8 days) than in Inceptisol (T1/2 28.7 days). No significant difference in the dissipation rate was observed at 1 and 10 μg g(-1) fortification levels.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2013; 443:904-909.

Abstract
Flubendiamide belongs to the modern insecticides applied in Japanese tea cultivation to control smaller tea tortrix and tea leaf roller. Since fate and behavior in soil have been only monitored sparsely and fragmentarily until today, laboratory tests were performed on sorption, leaching, biotransformation and photo-induced biotransformation of flubendiamide in two different soils. In batch equilibrium tests, K(d) and K(OC) values were 15 and 298 L kg(-1) for the Japanese tea field soil as well as 16 and 1610 L kg(-1) for the German arable field soil classifying flubendiamide to be moderately mobile and slightly mobile, respectively. The affinity to the tea field soil was additionally confirmed by soil column tests where flubendiamide was predominantly retarded in the topsoil layers resulting in a percolate contamination of only 0.002 mg L(-1). In the aerobic biotransformation tests, flubendiamide did not substantially disappear within the 122-d incubation period. Due to DT(50)>122 d, flubendiamide was assessed very persistent. Supplementary, photo-induced impacts on biotransformation were studied in a special laboratory irradiation system. Despite a 14-d irradiation period, photo-induced biotransformation in the tea field soil was not identifiable, neither by HPLC/DAD nor by LC/MS/MS. 3-d irradiation tests in photosensibilizing acetone, however, showed that the primary photo-transformation product desiodo-flubendiamide was formed. How far this photochemical reaction may also occur in soil of perennial tea plant stands, however, has to be checked in field studies.
