“…Analysis of field sample in LC-MS/MS showed that spiromesifen-enol was not present in any of the field samples over 2 years of study. Similar results were obtained from the multi-locational field trials conducted on tomato (Sharma et al 2014). Earlier, the residues of spiromesifen in field experiment were found in the form of unchanged parent compound (Weber 2005).…”

“…Both the parent compound, spiromesifen and metabolite, spiromesifen-enol were not detected in the cabbage at harvest. Treatment of spiromesifen to tomato resulted in residue-free crop at harvest (Sharma et al 2014). The dissipation pattern of spiromesifen on cabbage did not vary significantly in the studies conducted during 2013 and 2014.…”

“…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.…”

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.

Dissipation of spiromesifen and its metabolite, spiromesifen-enol, on tomato fruit, tomato leaf, and soil was studied in the open field and controlled environmental conditions. Sample preparation was carried out by QuEChERS method and analysis using LC-MS/MS. Method validation for analysis of the compounds was carried out as per "single laboratory method validation guidelines." Method validation studies gave satisfactory recoveries for spiromesifen and spiromesifen-enol (71.59-105.3%) with relative standard deviation (RSD) < 20%. LOD and LOQ of the method were 0.0015 μg mL and 0.005 mg kg, respectively. Spiromesifen residues on tomato fruits were 0.855 and 1.545 mg kg in open field and 0.976 and 1.670 mg kg under polyhouse condition, from treatments at the standard and double doses of 125 and 250 g a.i. ha, respectively. On tomato leaves, the residues were 5.64 and 8.226 mg kg in open field and 6.874 and 10.187 mg kg in the polyhouse. In soil, the residues were 0.532 and 1.032 mg kg and 0.486 and 0.925 mg kg under open field and polyhouse conditions, respectively. The half-life of degradation of spiromesifen on tomato fruit was 6-6.5 days in the open field and 8.1-9.3 days in the polyhouse. On tomato leaves, it was 7-7.6 and 17.6-18.4 days and in soil 5.6-7.4 and 8.4-9.5 days, respectively. Metabolite, spiromesifen-enol, was not detected in any of the sample throughout the study period. Photodegradation could be the major route for dissipation of spiromesifen in the tomato leaves, whereas in the fruits, it may be the combination of photodegradation and dilution due to fruit growth. The results of the study can be utilized for application of spiromesifen in plant protection of tomato crop under protected environmental conditions.
