“…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. So, it is suggested that a waiting period of one day is required to reduce the risk for safe consumption of chilli fruits.…”

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.

“…The residues of cypermethrin were determined by gas liquid chromatograph (GLC) model Shimadzu Model 2010 equipped with ECD (Ni 63 ), split ratio (1:10) and fused capillary column (SPB-5) 30 m × 0.32 mm ID, 0.25 µm film Persistence pattern (behaviour /style) and risk assessment of cypermethrin in chilli was studied by Singh et al (2015) following three applications of cypermethrin at 50 and 100 g a.i./ha at 10 day interval and reported half-life periods of 4.43 and 4.70 days at respective doses. Chandra et al (2014) studied the persistence of different insecticides and reported that the average initial deposits of cypermethrin were in the range of 0.378-0.862 mg/kg.…”

Persistence of cypermethrin and decontamination processes on reduction of cypermethrin residues was studied in okra (Abelmoschus esculentus L.) fruits following foliar application of formulation at dose of 50 and 100 g a. i./ha in a field at the Research field of CCS HAU, Hisar, India. Samples of okra fruits were collected periodically and residues were estimated by GC-ECD and confirmed by GC-MS. The average initial deposits of cypermethrin were 0.119 and 0.272 mg/kg in the okra fruits at single and double dose, respectively, one hour after the application. Residues of cypermethrin reached equal to below determination level (0.01mg/kg) on 10th in single dose and after 15 days at double dose. Half-life periods for cypermethrin were observed to be 2.74 days and 3.31 days at single and double dose, respectively following first order kinetics. Residues were below maximum residue limit (MRL) value of 0.2 mg/kg on 0 day in single dose and 1 day in double dose. Safe waiting period of 2 days has been suggested for safety sake. Decontamination processes were found very effective in reducing the residues of cypermethrin in okra fruits. Washing reduced the residues in the range of 39-41 %, whereas washing followed by boiling reduced 71 to 79% residues. In soil, residues of cypermethrin reached below detectable level of 0.005 mg/kg after 3rd and 5th days of application at single and double dose, respectively.
