“…VinothKumar (2020) reported that the R 2 = 0.992 in linearity studies. The 0.05 mg kg À1 LOQ for spiromesifen has been reported by several workers (George et al, 2014;Rao et al, 2015;Sharma et al, 2014;VinothKumar, 2020).…”

“…Findings of the linearity studies were similar to those of Sharma et al (2006)) who reported the R 2 value for spiromesifen to be 0.9881. VinothKumar (2020) reported that the R 2 = 0.992 in linearity studies. The 0.05 mg kg −1 LOQ for spiromesifen has been reported by several workers (George et al, 2014; Rao et al, 2015; Sharma et al, 2014; Sharma, Dubey, et al, 2007; VinothKumar, 2020).…”

“…Pesticide residues in food and their penetration into the food chain have sparked extensive public discussion. Few dissipation studies were performed to generate data on the effects of spiromesifen insecticides on chili fruits (Pathipati et al, 2017; Sharma, Rao, et al, 2007; Sushil et al, 2018; Varghese et al, 2011; VinothKumar, 2020; Viswanathan & Paul, 2020; Xavier & Chandran, 2016). Herein we report the dissipation kinetics and risk assessment of the effect of spiromesifen on chili fruits.…”

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.

“…EDI is estimated daily intake (mg kg − 1 body weight). In India, the estimated average vegetable intake per person is 200 g (Anonymous, 1999), with a maximum daily intake of 5% green chiles (10g) (Vinothkumar, 2020) by a person of average weight 55kg (Mukherjee & Gopal, 2000). Quantitatively determined RQ is greater or lower than 1 denote, substantial and minimal dietary risk, respectively.…”

An eco-friendly, premium and discerning method was validated for quantifying residue of fipronil and hexythiazox in chilli fruit using GC-ECD and HPLC–DAD, respectively. Within the measured range, all calibration curves exhibited a strong linear relationship (r > 0.99). The approach has a quantification limit of 0.01 mgkg− 1, and its recovery of individual molecules ranged from 81.23 to 91.23% with relative standard deviations (RSDs) below 3%. Fipronil and hexythiazox dissipate according to first order kinetics with half-life 2.99 and 2.83 days for single dose and 3.93 and 3.1 days for double dose, respectively. A safe holding period of 27 days for formulation and 27 and 19 days each for fipronil and hexythiazox was recommended for safe consumption of chilli considering the FSSAI maximum residual limit (MRL) of 0.01mgkg− 1 for both molecules. RQ < 1 indicates that use of present ready-mix formulation in chilli doesn't appear to furnish any dietary risks to human beings. A 53.68–75.19% reduction in the maximum residue was seen when fipronil and hexythiazox were removed using a simplistic decontamination method. Data was also analysed statistically including Shapiro wilk’s test (confirm normality of data), levene test (for homogeneity of variance) and Tukey’s HSD post-hoc test (to compare pair of groups) using IBM SPSS version 16.

“…Spiromesifen research focuses on its insecticidal activity against Bemisia tabaci , mites, and other pests and its dissipation time in vegetables. , Spiromesifen is highly insecticidal while remaining biologically and environmentally friendly, but this inevitably leads to resistance, so efforts have focused on spiromethyl ester derivatives. For example, compounds 11–16 − showed broad-spectrum insecticidal activities against Myzus persistae, Tetranychus urticae, Thrips tabaci, Diabrotica balteata, Frankliniella occidentalis, Nilaparvata lugens, Aphis craccivora, Aphis gossypii, Bemisia tabaci, Aonidiella aurantii, and Meloidogyne incognita exceeded 80% at 400 mg/L, and the insecticidal activities of most compounds to Bemisia tabaci and Aonidiella aurantii achieved levels of more than 80% effective even at 200 mg/L.…”

Spiro compounds are biologically active organic compounds with unique structures, found in a wide variety of natural products and drugs. They do not readily lead to drug resistance due to their unique mechanisms of action and have, therefore, attracted considerable attention regarding pesticide development. Analyzing structure−activity relationships (SARs) and summarizing the characteristics of spiro compounds with high activity are crucial steps in the design and development of new pesticides. This review mainly summarizes spiro compounds with insecticidal, bactericidal, fungicidal, herbicidal, antiviral, and plant growth regulating functions to provide insight for the creation of new spiro compound pesticides.
