“…The present of waxy hydrophobic layer on the leaves surface became a barrier to retain the fungicide on the surface and thus reduce the efficacy of the fungicide on pepper vine. This research finding is consistent with the results reported by Mukherjee and Gopal (2000) [9] who report that the safe waiting period for application of imidacloprid on brinjal were 5 and 7 days following application of 42 and 84 g a.i. of imidacloprid.…”

Persistence behavior of imidacloprid and beta-cyfluthrin in black pepper was studied following application of formulation of Solomon at 0.6 (recommended dose) and 1.2 (double recommended dose) g a.i./ha for one pepper production cycle. The results also showed that the Solomon at 0.6 mL/L concentration significantly suppressed the pest infestation in pepper vines. Pepper vine treated with Solomon produce more berries compared to control and showed no phytotoxicity. Analytical procedure of Solomon active ingredient was validated prior to actual analysis. Satisfactory recoveries ranging between 87.6%-106.7% were obtained for the fortified pepper berries samples. Results showed low level of imidacloprid and beta-cyfluthrin residues in dried pepper berries ranging between  0.01 mg/kg to 1.43 mg/kg and  0.01 mg/kg to 1.612 mg/kg respectively. The half-life value period for imidacloprid were found to be 2.06 and 2.30 days and for beta-cyfluthrin, these values were observed to be 1.57 and 1.49 days respectively at recommended and double recommended dose. Imidacloprid and beta-cyfluthrin residue dissipated below the limit of quantification (LOQ) of 0.01 mg/kg after 7 and 9 days respectively at recommended and double recommended dose. Soil sample collected 15 days after the last spray did not show the present of Imidacloprid and beta-cyfluthrin residue at their detection limit of 0.01 mg/kg.

“…The prescribed acceptable daily intake (ADI) of cypermethrin is 0.05 mg kg −1 body weight −1 day −1 (Sharma 2007). Maximum permissible intake (MPI) was obtained by multiplying the ADI with the weight of average Indian person (55 kg) (Mukherjee and Gopal 2000). MPI was calculated to be 2750 μg person −1 day −1 .…”

The study was conducted to observe the persistence pattern and risk assessment of cypermethrin in chilli fruits following three applications of cypermethrin (Super fighter 25 EC) at 50 and 100 g a.i. ha(-1) at 10-day interval. Residues of cypermethrin in chilli were estimated by gas liquid chromatography (GLC) and were confirmed by gas chromatography-mass spectrometry (GC-MS). The average initial deposits of cypermethrin in chilli fruits were found to be 1.46 and 3.11 mg kg(-1), at recommended and double the recommended dosages, respectively, following third application of the insecticide. Half-life periods for cypermethrin were found to be 4.43 and 4.70 days at recommended and double the recommended dosages, respectively. Residues of cypermethrin declined below its limit of quantification (LOQ) of 0.05 mg kg(-1) after 25 days at both the application dosages. Theoretical maximum residue contribution (TMRC) values were calculated from the residue data generated and were found to be below maximum permissible intake (MPI) even on 0 day. Therefore, according to our risk assessment studies, a waiting period of 1 day is suggested for consumption of chilli sprayed with cypermethrin at the recommended dosages.

Supervised field trials were conducted at four different agro-climatic zones in India to evaluate the dissipation pattern and risk assessment of flubendiamide on tomato. Flubendiamide 480 SC was sprayed on tomato at 48 and 96 g active ingredient (a.i.) ha(-1). Samples of tomato fruits were drawn at 0, 1, 3, 5, 7, 10, 15, and 20 days after treatment. Quantification of residues was done on a high-performance liquid chromatography (HPLC) device with a photo diode array detector. The limit of quantification (LOQ) of this method was found to be 0.01 mg kg(-1) while limit of detection (LOD) being 0.003 mg kg(-1). Residues of flubendiamide were found below the determination limit of 0.01 mg kg(-1) in 20 days at both the dosages in all the locations. The half-life of flubendiamide at an application rate of 48 g a.i. ha(-1) varied from 0.33 to 3.28 days and at 48-g a.i. ranged from 1.21 to 3.00 days. On the basis of data generated under the All India Network Project on Pesticide Residues, a preharvest interval (PHI) of 1 day has been recommended, and the flubendiamide 480 SC has been registered for its use on tomato by the Central Insecticide Board and Registration Committee, Ministry of Agriculture, Government of India. The maximum residue limit (MRL) of flubendiamide on tomato has been fixed by the Ministry of Health and Family Welfare, Government of India under Food Safety Standard Authority of India, as 0.07 μg g(-1) after its risk assessment.
