“…Soil factors like soil texture, temperature, pH, and organic carbon content influence residues, retention, and degradation rates of pesticides [22][23][24][25]. Degradation of ethofumesate has been reported in the medium silty loam soil; they found a two-stage degradation process rapid initial phase followed by a slower process [15].…”

Indiscriminate use of pesticides and growing awareness of environmental and health problems had led to monitoring their residues in soil and crops. Ethofumesate is one of the widely used herbicides for controlling weeds in sugar beet. Dissipation kinetics and terminal residues of ethofumesate were investigated in two diverse soils under subtropical field conditions. Ethofumesate dissipated slowly after application and follows biphasic first-order kinetics in soils. The average half-life for initial and later phases in sandy loam soil, respectively, was 14.54 and 20.42 and 51.83 and 65.21 days, while for silty clay loam, it was 10.09 and 13.00 and 71.42 and 73.10 days, respectively. Recoveries in soil, leaves, and beetroot ranged from 78.15 to 88.05, 77.01 to 88.58, and 76.25 to 84.50%, respectively. The quantitation limit for soil, roots, and leaves was 0.002 μg g−1. At harvest, no residues were detected in soils, leaves, and sugar beetroots. Residues were below the maximum residue limits in sugar beetroots and leaves as set by EU (0.2 ppm). Ethofumesate is safe from weed control and environmental aspects as it does not persist for a long duration in soils and does not appear to pose any adverse effect on human/animal health under subtropical field conditions.

“…DUR mobility is related to soil organic carbon content and soil texture (Landry et al, 2006). Tandon and Pant (2019) found that the persistence of DUR was stronger in sandy loam than in silty clay loam soil in sugarcane fields. The DT 50 of DUR in silty clay loam soil was 32.37 days when applied at 4 kg/ha, whereas it was 43.93 days in sandy loam soil.…”

“…Due to their high persistence and extensive use, DUR residues are frequently found in water, soil, and sediments ( Field et al, 2003 ; Giacomazzi and Cochet, 2004 ; Tandon and Pant, 2019 ). The highest concentration of DUR in sediment samples in the Brazilian Amazon region was 55.2 μg/kg ( Viana et al, 2019 ).…”

“…It is widely used for the pre- or postemergence control of various types of broadleaf and grassy weeds in diverse crops such as cotton, fruit, and cereals, as well as for algal control in fish production ponds, with application doses ranging from 0.45 to 3 kg a.i. ha –1 ( Castillo et al, 2006 ; Stork et al, 2008 ; Lu et al, 2019 ; Tandon and Pant, 2019 ). It has also been used in antifouling paints for boating activities and non-crop applications such as roads, garden paths, and railway lines ( Schrader et al, 2004 ; Hussain et al, 2015 ).…”

Emerging Strategies for the Bioremediation of the Phenylurea Herbicide Diuron

Diuron (DUR) is a phenylurea herbicide widely used for the effective control of most annual and perennial weeds in farming areas. The extensive use of DUR has led to its widespread presence in soil, sediment, and aquatic environments, which poses a threat to non-target crops, animals, humans, and ecosystems. Therefore, the removal of DUR from contaminated environments has been a hot topic for researchers in recent decades. Bioremediation seldom leaves harmful intermediate metabolites and is emerging as the most effective and eco-friendly strategy for removing DUR from the environment. Microorganisms, such as bacteria, fungi, and actinomycetes, can use DUR as their sole source of carbon. Some of them have been isolated, including organisms from the bacterial genera Arthrobacter, Bacillus, Vagococcus, Burkholderia, Micrococcus, Stenotrophomonas, and Pseudomonas and fungal genera Aspergillus, Pycnoporus, Pluteus, Trametes, Neurospora, Cunninghamella, and Mortierella. A number of studies have investigated the toxicity and fate of DUR, its degradation pathways and metabolites, and DUR-degrading hydrolases and related genes. However, few reviews have focused on the microbial degradation and biochemical mechanisms of DUR. The common microbial degradation pathway for DUR is via transformation to 3,4-dichloroaniline, which is then metabolized through two different metabolic pathways: dehalogenation and hydroxylation, the products of which are further degraded via cooperative metabolism. Microbial degradation hydrolases, including PuhA, PuhB, LibA, HylA, Phh, Mhh, and LahB, provide new knowledge about the underlying pathways governing DUR metabolism. The present review summarizes the state-of-the-art knowledge regarding (1) the environmental occurrence and toxicity of DUR, (2) newly isolated and identified DUR-degrading microbes and their enzymes/genes, and (3) the bioremediation of DUR in soil and water environments. This review further updates the recent knowledge on bioremediation strategies with a focus on the metabolic pathways and molecular mechanisms involved in the bioremediation of DUR.

“…Injudicious use of pesticides pollutes environment, as they enter the biosphere through different modes after being discharged on soil surface or canopy. Only 1% of the sprayed pesticides are effective, while 99% of pesticides applied are released to non-target soils, water bodies and atmosphere, and finally absorbed by almost every organism leading to contamination of environment, residues in soil, water and food, damage to soil microorganisms including earthworms, negative effect on plant biodiversity, toxicity to human and animals, shifts in weed flora and appearance of resistance in pests species [1][2][3][4].…”

A sensitive and reliable method for simultaneous determination of oryzalin and ethofumesate residues in pantnagar soil and water was validated. The compounds were extracted by LLE with dichloromethane from water, and acetone:methanol mixture from soil followed by SPE cleanup. Detection and quantification was done by RP-HPLC using mobile phase methanol:water (70:30, v/v) at 280 nm. The developed method showed satisfactory validation results with linearity (0.99), relative standard deviations (1.55 and 1.73%), and limit of quantification (0.002 μg g−1 and 0.005 μg g−1) for ethofumesate and oryzalin, respectively. Recoveries ranged for oryzalin and ethofumesate from 79.80–90.52, 75.58–86.04% (soil) and 83.50–95.92, 82.28–94.60% (water), respectively. The method could be used for routine high-throughput detection and determination of these compounds.
