“…The reported PHIs for spiromesifen on chilli were 14.5 and 16.8 days from treatments at 96 and 192 g a.i. ha −1 (Sharma et al 2006), which was similar to the results obtained in the current study.…”

“…The half-lives of spiromesifen from treatment at 96 g a.i. ha −1 varied from 5.5 to 6.2 days on apple, 2.18 to 2.4 days on chilli, 5.0 to 8.5 days on tea, and 0.93 to 1.38 days on tomato from multi-locational field studies carried out earlier (Sharma et al 2005;Sharma et al 2006;Sharma et al 2007;Sharma et al 2014). The preharvest interval was calculated based on the European Union prescribed maximum residue limit (MRL) of 0.02 mg kg − 1 for spiromesifen on cabbage (Anonymous 2012).…”

“…Spiromesifen residues were not detected in soil samples collected after 40 days from treated apple field and 15 days from treated tomato field (Sharma et al 2005;Sharma et al 2014). Soil collected from treated cotton and chilli field was free from spiromesifen residues at harvest (Sharma et al 2006). …”

“…Therefore, it is essential to study the persistence of pesticide residues on cabbage, whenever it is applied for crop protection. A multi-locational trial of spiromesifen on chilli and tomato has been carried out to study the dissipation pattern and to work out the half-life of spiromesifen on these crops (Sharma et al 2006;Sharma et al 2014). No such information is available for cabbage.…”

“…Residue analysis of spiromesifen has been carried out on apple, chilli, cotton, and tomato using multiple steps, large volume of organic solvents, and gas chromatograph-mass spectrometry (GC-MS) (Sharma et al 2005;Sharma et al 2006;Sharma et al 2014). QuEChERS method is a rapid, cost-effective, singlestep buffered acetonitrile extraction and dispersivesolid phase extraction (d-SPE) cleanup method (Anastassiades et al 2003).…”

Spiromesifen is a new class of insecticide used for the control of whiteflies and mites which have developed resistance to the more commonly used neonicotinoids. Dissipation pattern of spiromesifen on cabbage was evaluated over 2 years by conducting supervised field studies as per good agricultural practices. Cabbage and soil samples were extracted and purified using modified QuEChERS method and analyzed through gas chromatography (GC). Confirmatory studies were carried out by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The recoveries of spiromesifen from cabbage and soil were between 85.44 and 103.37% with the relative standard deviation (RSD) between 3.2 and 9.4% (n = 6). The limit of detection (LOD) and limit of quantification (LOQ) were 0.003 μg mL(-1) and 0.01 mg kg(-1), respectively. The measurement uncertainties (MUs) were within 9.9-14.9%. Initial residues of spiromesifen on cabbage were 0.640 and 1.549 mg kg(-1) during 2013 and 0.723 and 1.438 mg kg(-1) during 2014 from treatments at standard and double doses of 125 and 250 g active ingredient (a.i.) ha(-1), respectively. Spiromesifen residue dissipation followed first-order rate kinetics, and it degraded within the half-lives of 2.9 and 3.9 days during 2013 and 3.2 and 4.5 days during 2014. The residue levels reached below the maximum residue limit (MRL; 0.02 mg kg(-1)) within 15-17 days at the standard dose and 24-27 days at the double dose. The field soil analyzed at harvest (30 days) was free from spiromesifen residues. Metabolite spiromesifen-enol was not detected in any sample which was confirmed through LC-MS/MS analysis.

A supervised field trial was designed in Rajasthan Agricultural Research Institute, Durgapura, Jaipur, Rajasthan, to assess the dissipation and persistence of spiromesifen in chili fruits. Spiromesifen (22.9% suspension concentrate) was sprayed two times at an interval of 10 days at the recommended dose (96 g. a.i. ha−1) and double the recommended dose (192 g. a.i. ha−1) with four replications. Sampling was done according to the planned interval of days after the second spray. Extraction and cleanup were performed using the modified QuEChERS (quick, easy, cheap, effective, rugged, and safe) method and the spiromesifen residue was analyzed by GC–electron capture detector and confirmation performed using GC–MS. The average initial deposit of spiromesifen was 1.207 mg kg−1and 1.948 mg kg−1at the recommended and double the recommended dose, respectively. The half‐life values of spiromesifen ranged between 2.7 and 3.2 days at the recommended and double the recommended dose. The safe waiting period was calculated for the respective doses and it was concluded that an average of 7 days is safe for picking. The FSSAI (Food Safety and Standards Authority of India) have set the maximum residue limit of 0.1 mg kg−1 for spiromesifen in green chili. The theoretical maximum residue contribution value of spiromesifen was lower than the maximum permissible intake at both the applications on the 0th day. Hence, there will be no adverse effects on human health after consumption of green chilies.
