Residual dynamics of thiacloprid in medical herbs marjoram, thyme, and camomile in soil

Dissipation rate of thiacloprid and its control effect against Bemisia tabaci in greenhouse tomato after soil application

“…However, Bikramjit and Gajbhiye found that the dissipation of thiacloprid in soil followed first‐order kinetics, with half‐lives of 3.2–3.3 days, and that thiacloprid residues in the plough layer persisted beyond 16 days, but no residues were detected after 22 days with soil application. Yu et al calculated that the half‐life of thiacloprid in soil was 3.5–3.6 days. Generally, the dissipation of pesticides in soil depends on the soil type and the environmental conditions.…”

Chemometric-assisted QuEChERS extraction method for the residual analysis of thiacloprid, spirotetramat and spirotetramat’s four metabolites in pepper: Application of their dissipation patterns

“…The residue dynamics of thiacloprid have been studied in different matrices, including medicinal herbs, tomatoes, eggplants, cabbage and soil (Dong et al, 2014;Omirou, Vryzas, Papadopoulou-Mourkidou, & Economou, 2009;Saimandir, Gopal, & Walia, 2009;Wang, Guan, & Zhang, 2011;Yu, Wu, Stahler, & Pestemer, 2007). Only two published papers were available on the behaviour of spirotetramat in plants (i.e., cotton, mango and soil) (Mohapatra, Deepa, Lekha, et al, 2012;Pandiselvi, Sathiyanarayanan, & Ramesh, 2010).…”

The disappearance rate and risk assessment of thiacloprid residues in Asian pear using liquid chromatography confirmed with tandem mass spectrometry

“…The variation in dissipation pattern might be attributed to the fruit size (bigger in site 1), as the temperature and humidity were similar at both sites (Figure ). In addition, the differences between the reported half‐lives are also attributed to the plant species and cultivation (open field vs. greenhouse), as can be seen in tomatoes (1.9 days under greenhouse condition; Omiron, Vryzas, Papadopoulou‐Mourkidou, & Economou, ), apples and tea (3.8–4.6 days and 3.3–days; Dubey, Patyal, Harma, Thakur, & Kumar, ), medicinal herbs (marjoram, thyme and chamomile, 0.7–1.2 days; Yu, Wu, Stahler, & Pestemer, ) and eggplant (11.1–11.6 days; Saimandir, Gopal, & Walia, ).…”

“…In addition, the differences between the reported half-lives are also and chamomile, 0.7-1.2 days; Yu, Wu, Stahler, & Pestemer, 2007) and eggplant (11.1-11.6 days;Saimandir, Gopal, & Walia, 2009).…”
