“…Similarly, photolysis has also been reported as the main degradation pathway of trifloxystrobin under field conditions, and the number of sunshine hours is the key influencing factor for the photolysis process (Wang et al, 2015). Trifloxystrobin residue was found in tomato, whereas its metabolite trifloxystrobin acid was observed in soil (Wang et al, 2014). Reddy et al (2013) reported that the organic matter content, microbial population and soil moisture affected the dissipation of pyraclostrobin, and their results showed the more rapid dissipation of pyraclostrobin under wet air conditions compared with dry conditions; moreover, the most rapid pyraclostrobin dissipation occurred in sludgeamended soil (t 1/2 9.2 days).…”

Strobilurin fungicides have been widely used in agricultural fields for decades. These pesticides are designed to manage fungal pathogens, although their broad-spectrum mode of action also produces non-target impacts. Therefore, the removal of strobilurins from ecosystems has received much attention. Different remediation technologies have been developed to eliminate pesticide residues from soil/water environments, such as photodecomposition, ozonation, adsorption, incineration, and biodegradation. Compared with conventional methods, bioremediation is considered a cost-effective and ecofriendly approach for the removal of pesticide residues. Several strobilurindegrading microbes and microbial communities have been reported to effectively utilize pesticide residues as a carbon and nitrogen source. The degradation pathways of strobilurins and the fate of several metabolites have been reported. Further indepth studies based on molecular biology and genetics are needed to elaborate their role in the evolution of novel catabolic pathways and the microbial degradation of strobilurins. The present review summarizes recent progress in strobilurin degradation and comprehensively discusses the potential of strobilurin-degrading microorganisms in the bioremediation of contaminated environments.

“…There are previous reports on the dissipation pattern and final residues of difenoconazole and trifloxystrobin in some other matrices, such as rice (Cao et al, 2015;Chen et al, 2014;Li, Wang, Hao, & Han, 2014), tomato (Kong et al, 2012;Wang et al, 2014), apple (Guo, Li, Guo, & Wang, 2010;Wang, Wu, Zhang, Wang, & Zhang, 2015) and many other principal fruits and vegetables (Banerjee, Oulkar, Patil, Dasgupta, & Adsule, 2008;Liu et al, 2011;Mohapatra, 2015;Park et al, 2007). In previous papers, trifloxystrobin was determined by HPLC (Likas & Tsiropoulos, 2014;Zhu, Dai, Fang, & Zhu, 2013), GC with electron capture (Likas, Tsiropoulos, & Miliadis, 2007) or GC with MS (Paramasivam et al, 2015), while determination of difenoconazole was mainly developed by GC (Guo et al, 2010) and UPLC-MS/MS (Kong et al, 2012).…”

An optimized quick, easy, cheap, effective, rugged and safe method for the simultaneous determination of difenoconazole, trifloxystrobin and its metabolite trifloxystrobin acid residues in watermelon and soil was developed and validated by gas chromatography with tandem mass spectrometry. The samples were extracted with acetonitrile (1% formic acid) and cleaned up by dispersive solid-phase extraction with octadecylsilane sorbent. The limit of quantification of the method was 0.01 mg/kg, and the limit of detection was 0.003 mg/kg for all three analytes. The recoveries of the fungicides in watermelon, pulp and soil were 72.32-99.20% for difenoconazole, 74.68-87.72% for trifloxystrobin and 78.59-92.66% for trifloxystrobin acid with relative standard deviations of 1.34-14.04%. The dissipation dynamics of difenoconazole and trifloxystrobin in watermelon and soil followed the first-order kinetics with half-lives of 3.2-8.8 days in both locations. The final residue levels of difenoconazole and trifloxystrobin were below 0.1 mg/kg (maximum residue level [MRL] set by China) and 0.2 mg/kg (MRL set by European Union), respectively, in pulp samples collected 14 days after the last application. These results could help Chinese authorities to establish MRL of trifloxystrobin in watermelon and provide guidance for the safe and proper application of both fungicides on watermelon.

“…In brief, the literature on the determination of TFS and TFSA residues mainly focused on plant matrices such as rice (Luo et al, 2020), tomato (Wang et al, 2014) and grapes (Likas et al, 2007), while there are few studies on the residues of TFS and its metabolite in animal‐derived food. Han, Sun, and Wu (2008) developed a method for the determination of TFS and TFSA by gas chromatography in peanut oil, milk and juices.…”

Trifloxystrobin (TFS) is a widely used strobilurin fungicide and its residues accumulating in animal-derived food could result in potential harm to consumers. By optimization of extraction solvents and cleanup sorbents, a residue analysis method for TFS and its metabolite trifloxystrobin acid (TFSA) was established in milk, eggs and pork based on QuEChERS sample preparation and LC-MS/MS. The calibration curves exhibited good linearity with determination coefficients (R 2 ) >0.9930 over the range of 0.5-250 ng/ml for both TFS and TFSA. The recoveries of the two analytes were 81-100% with RSD 3-10% and 76-96% with RSD 2-13%, respectively. The limit of quantification (LOQ) was 1 ng/g for both analytes. The milk, egg and pork samples, 30 each, were collected from the 30 main producing regions in China, and residues of TFS and TFSA were analyzed. The concentrations of both analytes were lower than the corresponding LOQs and maximum residue limits. Long-term dietary risk assessment showed that the hazard quotients were 0.001-0.003%, indicating an absence of unacceptable risks in milk, eggs and pork to the health of common consumers in China.
