Dissipation of flubendiamide in/on Brinjal (Solanum melongena) fruits

Abstract

A field experiment was conducted at Anand Agricultural University, Anand during Sept-Dec, 2009 to study the rate of degradation of flubendiamide in/on brinjal fruits following foliar application of Fame 480 SC at 90 (standard dose) and 180 (double dose) g a.i. ha( -1). The residues estimated using HPLC revealed persistence of flubendiamide in/on brinjal till 3rd and 7th day after the last spray at standard and double dose, respectively. The residues of flubendiamamde were reported as parent compound, and no desiodo metabolite was detected. The initial deposits of 0.17 and 0.42 μg g( -1) in/on brinjal fruits reached below determination level of 0.05 μg g( -1) on the 5th and 10th day at standard and double dose, respectively. The half life of flubendiamide on brinjal fruits ranged from 2.68 to 2.55 days. Soil samples analyzed on the 15th day after the last spray revealed residues at below determination level (0.05 μg g( -1)) at either dose of application.

Residual behavior and risk assessment of flubendiamide on tomato at different agro-climatic conditions in India

“…Similar results were reported in cabbage (Mohapatra et al 2010) and in brinjal (Chawla et al 2011) and in tomato (Paramasivam and Banerjee 2012). The Paramasivam and Banerjee (2011).…”

“…The half-life values of flubendiamide on brinjal were observed to be 0.62 and 0.54 days, respectively, following three applications of flubendiamide 480 SC at 90 and 180 g a.i.ha −1 on brinjal fruits (Takkar et al 2012). Similarly, the half-lives of flubendiamide were reported to be 2.68 and 2.55 days following application of flubendiamide at 90 and 180 g a.i.ha −1 on brinjal fruits (Chawla et al 2011).…”

Insecticides chlorantraniliprole and flubendiamide in Aster scaber: Dissipation kinetics, processing effects, and risk assessment

“…Studies have reported the dissipation and dietary risk assessment of CAP and FBD in various plant samples, including brinjal, kale, paprika, perilla leaves, strawberries, tea leaves, and tomatoes [ [8] , [9] , [10] , [11] , [12] , [13] ]. Pesticide residue levels can vary significantly depending on whether the crops are grown in a greenhouse or in open fields.…”
