“…The waiting period worked out for cypermethrin was 5.16 days at SD and 8.42 days at 2×SD (Table 2). Similar work has been done by Solanki et al (2019) using combiproduct of chlorpyrifos and cypermethrin in sapota and have reported waiting period of 4 to 5 days used as combi-product. Likewise, Gupta et al (2011) have studied the persistence of the chlorpyrifos, profenofos and cypermethrin in tomato using pre-mix formulation (Chlorpyriphos 50% + Cypermethrin 5%) and (Profenofos 40% + Cypermethrin 5%) and found that in pre-mix formulation the residues of profenofos persisted up to 7-15 days while the residues of cypermethrin and chlorpyrifos persist up to 0-7 days only.…”

“…Prior to analysis, soil samples were mixed thoroughly, air dried milled and passed through 2 mm sieve and then subjected to pesticide residues analysis. Extraction and clean-up of profenofos and cypermethrin residues in sapota fruits and soil were carried out according to QuEChERS method with certain modifications (Sharma, 2013;Solanki et al, 2019).…”

Sapota, a prominent and economically important fruit crop of India is susceptible to several species of insect and mite pests. Several pesticides formulations are used to control the pest damage in sapota. The present investigation was aimed to study the dissipation and persistence behaviour of combi-product profenofos 40% + cypermethrin 4% (44EC) at the standard dose (SD) (1162 g a.i. ha-1+106 g a.i. ha-1) and double to standard dose (2×SD) (2324 g a.i. ha-1+212 g a.i. ha-1) in/on sapota under tropical agro-climatic conditions of South Gujarat in India. Prior to quantitative analysis of pesticide residue on Gas chromatography with electron captured detector (GC-ECD), the modified Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) based method was validated on its accuracy, precision, linearity and sensitivity. Profenofos persisted in sapota up to 30 days with the half-lives of 5.65 and 7.34 days at SD and 2×SD, respectively. Cypermethrin dissipated at a rapid pace and was below quantitation limit (BQL) on 7 days at either dose of application; the half-life values recorded were 3.27 and 4.43 days at SD and 2×SD, respectively. This is the first case study that reflects 14 days as a waiting period after the last spray of combi-product (44EC) at standard dose facilitates the residue-free sapota fruits. Further, the health risk index (HRI<1) and Health Index (HI %< 100%) indicates that the application of combi-product profenofos 40% + cypermethrin 4% (44EC) at standard dose could not pose any health risk to Indian consumers.

“…The present finding on DT 50 of chlorantraniliprole is differing from the results reported with DT 50 for cauliflower 1.25–1.36 days ( Kar et al., 2012 ), tomato 3.30 days ( Malhat et al., 2012 ) okra 1.60–1.70 days ( Vijayasree et al., 2015 ), brinjal 1.58–1.80 days ( Vijayasree et al., 2015 ), green chilli 1.58–1.80 days ( Ahlawat et al., 2019 ), 1.26 days ( Paramasivam, 2020 ). This variation might be the resultant of the prevailing environmental factors and processes viz., temperature, relative humidity, volatilization and photo-degradation at field conditions ( Dong et al., 2011 ; Kar et al., 2012 ; Zhang et al., 2012 ; Solanki et al., 2019 ; Paramasivam, 2020 ) which are not consistent in different geographical regions.…”

“…The pace of consumption of above combination product is picked in the past few years among the farmers of India to beat losses of pigeonpea. The residues of insecticides (chlorantraniliprole and λ-cyhalothrin) may persist in food commodities which may be toxic to human health through dietary intake ( Kelageri et al., 2017 ; Solanki et al., 2019 ; Paramasivam, 2020 ; Sharma et al., 2021 ).…”

Pigeonpea ( Cajanus cajan L.) is an annually cultivated food and forage crop, attacked by a large number of pests mainly pod borer ( Helicoverpa armigera ). For the control of this insect pest, a combination of broad-spectrum insecticides viz., chlorantraniliprole and λ-cyhalothrin have been in use to reduce the pod damage and increase crop production worldwide. Therefore, a field trial was conducted to study dissipation and persistence behavior of insecticides combination (Chlorantraniliprole 9.26 % + λ-cyhalothrin 4.63 % ZC) in/on pigeonpea at the recommended dose (RD) 30 g a.i./ha and double recommended dose 60 g a.i./ha (2RD). The quantitative analysis was performed using ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) for chlorantraniliprole and Gas chromatography with electron captured detector (GC-ECD) for λ-cyhalothrin. The Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) method was validated for its accuracy, precision and sensitivity. The chlorantraniliprole persisted upto 30 days and λ-cyhalothrin persisted upto 10 days at RD and 20 days at 2RD. The half-lives (DT 50 ) of chlorantraniliprole and λ-cyhalothrin were from 4.95 to 5.78 days and 2.48–4.33 days at recommended and double recommended dose in pigeonpea, respectively. However, residues of both insecticides measured from soil at 30 th day and harvest time were below the limit of quantification (LOQ). The waiting period deciphered for chlorantraniliprole and λ-cyhalothrin applied as combi-product was 9 days at recommended dose. Dietary risk assessment (Risk quotient<1) was performed on the basis of field trial suggested the application of chlorantraniliprole and λ-cyhalothrin as combi-product at recommended dose is safe for the consumers.

“…The contemporary finding on DT50 of spiromesifen is differing from the results reported with DT50 for brinjal 1.40-2.18 days (Vinothkumar et al, 2018) and other fruits and vegetables like, green chilli 2.18-2.40 days (Sharma et al, 2007), okra 1.65-1.68 days (Raj et al, 2012), tomato 0.93-1.38 days (Sharma et al, 2014) and cucumber 2.12-2.19 days (Banerjee and Agyani, 2019). This variation could be the effect of the major environmental factors and processes viz., relative humidity, temperature, wind, volatilization and photodegradation at field conditions (Sharma et al, 2014;Mate et al, 2015;Vinothkumar et al, 2018;Banerjee and Agyani, 2019;Solanki et al, 2019) which are not reliable in different geographical zones.…”

Brinjal (Solanum melongena) is a versatile crop infected by several insects and pests. For the control of these pests, spiromesifen insecticide has been in use to reduce the damage and increase crop production worldwide. Therefore, a field trial was conducted to study dissipation and persistence behavior of spiromesifen 22.9% w/w SC in/on brinjal at the recommended dose (RD) 96 g a.i./ha and double to recommended dose 192 g a.i./ha (2RD). The quantitative analysis of spiromesifen was performed using ultra-high performance liquid chromatography- tandem mass spectrometry (UHPLC-MS/MS). Samples were processed by the Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) method. The analytical method was validated using various parameters viz., linearity (R2≥0.99), sensitivity (LOD and LOQ), accuracy (recovery=70-120%) and precision (RSD≤20%). The spiroemsifen persisted up to 3 days at RD and 5 days at 2RD. The dissipation half-life (DT50) of spriromesifen was 3.64 and 4.10 days at RD and 2RD in brinjal, respectively. However, residues of spiromesifen measured from soil at 0th (2 hr) day and 10th day were below the limit of quantification (BQL). The waiting period deciphered for spiromesifen applied in brinjal was 1 day at the recommended dose. Further, health risk assessment (health risk index<1 and percent health index<100) was performed on the basis of field trial which suggested that the application of spiromesifen in brinjal crop at recommended dose is safe for the end-users.
