“…Final residue testing revealed a positive correlation between application dose and spraying frequency and the risk of residue in the harvested broccolini". Also, Liu et al [9] reported that "the final residues of the four pesticides spirotetramat, flonicamid, thiamethoxam and tolfenpyrad in eggplant after the final applications at 7 and 10 days were 0.01-0.21, 0.085-0.26, 0.05-0.078 and 0.01-0.21 mg/kg, respectively with half-lives ranging from 3.4 to 14.5 days". Biswajit [10] tested "three dosages of tolfenpyrad 15% EC (100, 125, and 150 g a.i.…”

The use of Tolfenpyrad, a broad-spectrum insecticide in preventing the crop losses, studies on its dissipation pattern and safe waiting period required were studied. Tolfenpyrad 15 EC @ 150 g a.i. ha-1 at recommended dose under field conditions to assess the differences in rate of dissipation, and also to recommend safe waiting periods and half-life period based on MRLs established by FSSAI. Tolfenpyrad was sprayed two times at head formation stage and cabbage samples collected at regular intervals were analysed for residues. The dissipation pattern of tolfenpyrad 15 EC was studied collecting samples at regular intervals i.e, 0, 1, 3, 5, 7, 10,15 and 20 days after last spray and analyzed. The initial deposits of 0.184 mg kg-1 tolfenpyrad recorded at 2 hours after last spray dissipated to 0.145, 0.086, 0.021, 0.010 mg kg-1 with dissipation percent of 21.19, 53.26, 88.58 and 94.56 at 1,3,5,7 days after final spray. The tolfenpyrad residues dissipated to less than LOQ (<LOQ) of 0.01 mg kg-1 after 10 days showing a hundred per cent dissipation. The safe waiting period and half-life for tolfenpyrad were 7.09 and 1.590 days, respectively. The residues of tolfenpyrad in cabbage and soil samples were less than LOQ both field conditions at harvest (20 days after last spray).

“…The insecticide tolfenpyrad that is widely utilized in agriculture poses environmental concerns due to its persistent nature in aquatic systems, potentially leading to contamination. Tolfenpyrad residues have been reported in Pu'er tea, 10 eggplant, and Chinese cabbage fields 11,12 . However, there is a paucity of reports on the effects of tolfenpyrad on aquatic organisms.…”

“…Tolfenpyrad residues have been reported in Pu'er tea, 10 eggplant, and Chinese cabbage fields. 11,12 However, there is a paucity of reports on the effects of tolfenpyrad on aquatic organisms. Our research findings reveal that tolfenpyrad exposure significantly reduces the survival rate of zebrafish, accompanied by pronounced effects on body length and spontaneous movement frequency.…”

Tolfenpyrad, a highly effective and broad‐spectrum insecticide and acaricide extensively utilized in agriculture, presents a potential hazard to nontarget organisms. This study was designed to explore the toxic mechanisms of tolfenpyrad on zebrafish embryos. Between 24 and 96 h after exposure of the fertilized embryos to tolfenpyrad at concentrations ranging from 0.001 to 0.016 mg/L (96 h‐LC50 = 0.017 mg/L), lethal effects were apparent, accompanied with notable anomalies including pericardial edema, increased pericardial area, diminished heart rate, and an elongated distance between the venous sinus and the arterial bulb. Tolfenpyrad elicited noteworthy alterations in the expression of genes pertinent to cardiac development and apoptosis, with the most pronounced changes observed in the cardiac development‐related genes of bone morphogenetic protein 2b (bmp2b) and p53 upregulated modulator of apoptosis (puma). The findings underscore that tolfenpyrad induces severe cardiac toxicity and mitochondrial damage in zebrafish embryos. This data is imperative for a comprehensive assessment of tolfenpyrad risks to aquatic ecosystems, particularly considering the limited knowledge regarding its detrimental impact on aquatic vertebrates.
