“…For both single and double the recommended dosages, the half-life of fenpropathrin in chilli following third application was found to be 2.41 and 1.92 day, respectively. Similar findings were observed by Ahmed and Mohammed (2014) who reported deposits of 1.53 and 1.76 mg/kg in squash fruit along with garden rocket following treatment of fenpropathrin 20 EC @ 238 g a.i./ha with half-life values of 1.78 days besides 1.85 days, accordingly. Singh et al (2015) suggested that spraying of cypermethrin @ 50 and 100 g a.i./ha, the residual deposits were found to be 1.46 and 3.11 mg/ kg declined below its LOQ of 0.05 mg kg -1 after 25 days with T 1/2 of 4.43 days as well as 4.70 days, respectively.…”

Spraying of chilli crop with fenpropathrin @ 75 and 150 g a.i./ ha led to the initial residues ranging from 0.12 to 0.14 and 0.19 to 0.22 mg/kg, respectively. Fenpropathrin residues in chilli dissipated below the limit of quantification after 3 and 5 days at low and high doses. The half-life of fenpropathrin in chilli was calculated to be 2.41 and 1.92 days. Residues of fenpropathrin on chilli collected 0 day after spray was below MRL following application @ 75 g a.i./ ha. Among various household processing methods, KMnO4 solution reduces 72.50 per cent residue washing, boiling, dipping in sodium bicarbonate solution, salt solution and acetic acid solution, respectively after 0 (2 hrs after spray) day of fenpropathrin @ 75 g a.i./ ha after third spraying in chilli.

Since the 1990s, the insect growth regulator pyriproxyfen and pyrethroids such as fenpropathrin have been widely used to reduce pest populations in agriculture. The widespread use of these insecticides makes it essential for researchers to understand how they behave in terrestrial ecosystems and how they can be detected. This work reviewed the most effective analytical techniques used to detect pyriproxyfen and fenpropathrin in various samples. The degradation of pyriproxyfen and fenpropathrin in soil takes time, but in aerobic environments, pyriproxyfen and fenpropathrin are degraded rapidly following first-order kinetics or pseudo-first-order kinetics. Both insecticides tend to adsorb on soils and are not susceptible to leaching into groundwater. Based on greenhouse or field conditions, both insecticides degrade differently by following first-order kinetics, and their half-lives in plants range from one to three weeks. Since both insecticide residues are soluble in acetone, hexane, ethyl acetate, and acetonitrile, they can be extracted in those solvents. They can also be processed in a variety of ways discussed in this paper. Ultimately, the review explains how fate profiles of pyriproxyfen and fenpropathrin in soil and plants affect these molecules' adverse effects on non-target organisms.
