“…Singh and Battu (2012) reported that the initial deposit averages of spinosad in cabbage were 0.33 and 0.56 mg kg -1 at single and double dosages, respectively, and the half-life values were 1.4 and 1.5 d at the same dosages. On the other hand, the half-life value of abamectin was 4.1 d. This value was higher than that (1.06 d) described by Abd Al-Rahman et al (2012) on the residue analysis of abamectin in tomato fruits under field conditions. However, Ahmed (2011) indicated that the half-life time for abamectin was calculated to be 3.93, 6.16, and 2.2 d for orange, strawberry, and cucumber, respectively.…”

A simple and accurate method coupled with a gas chromatography-nitrogen phosphorus detector was developed to detect cyprodinil and fludioxonil in grape and soil. The accuracy and precision of the method in detecting the two fungicides were evaluated by conducting intra- and inter-day recovery experiments. The limits of detection were 0.017 mg/kg for cyprodinil and 0.030 mg/kg for fludioxonil. The limits of quantitation were 0.05 mg/kg for cyprodinil and 0.10 mg/kg for fludioxonil in grape and soil. The recoveries of the fungicides in grape and soil were investigated at three spiked levels and were found to range from 85.81 to 102.94% for cyprodinil and from 92.00 to 106.86% for fludioxonil, with relative standard deviations below 7%. Field experiments were conducted in two experimental locations in China. The half-lives of cyprodinil were 9.6-20.8 days in grape and 5.8-15.6 day in soil, and the half-lives of fludioxonil were 6.2-7.2 days in grape and 6.0-12.1 days in soil. When the cyprodinil and fludioxonil 62% water-dispersible granule formulation was sprayed at a low dosage three times, terminal residues of cyprodinil and fludioxonil were below 1.0 mg/kg in grape 14 days after harvest. This work may serve as a reference to establish the maximum residue limits for cyprodinil and fludioxonil in grape and promote the proper and safe use of these two fungicides.

“…Therefore, pymetrozine residues may lead to potential health injury. Several analysis methods have been developed for residues of pymetrozine in different matrices, such as differential pulse polarographic method (DPP), liquid chromatography (LC) with UV/vis, diode array detection (DAD), and mass spectrometry (MS); however, the fast and efficient method is LC with mass spectrometry (MS) (Guan et al 2013;Abd Al-Rahman et al 2012;Lehotay et al 2010;Mercan et al 2007;Lee et al 2011). A simple, sensitive, and selective method with LC-MS/MS for quantification of pymetrozine was developed to study the dissipation behavior and final residue of pymetrozine in rice field ecosystem.…”

The dissipation and residue of pymetrozine in rice field ecosystem were studied based on a novel and reliable analytical method for pymetrozine in paddy water, soil, rice straw, brown rice, and rice husk. The pymetrozine residues were extracted with acetonitrile and cleaned up by Carb-NH 2 SPE cartridge and determined by high-performance liquid chromatography electrospray ionization tandem mass spectrometry (LC-ESI-MS-MS). The dissipation of pymetrozine followed first-order kinetics and its half-lives ranged from 1.7 to 1.8 days in paddy water, 5.1 to 5.7 days in soil, and 2.3 to 2.6 days in rice straw, respectively. At harvest time, the highest final residues of pymetrozine varied in soil among three geographical fields and were below the limit of detection in rice tissues. The recommended dosage was considered to be safe for human beings and animals, and the results were helpful in setting maximum residue limit for pymetrozine in rice.
