Dissipation and Persistence of Flubendiamide and Thiacloprid in/on Tomato and Soil

Abstract

Flubendiamide, a phthalic acid diamide protects the plants against a broad range of economically important lepidopterus pests and thiacloprid a second generation neonicotinoid is effective against the sucking insects, white flies and jassids. To estimate the residues of flubendiamide and thiacloprid on tomato, analytical methods were validated by conducting recovery studies, residues were quantified by using HPLC on C(18) column and PDA at 260 λ. Residues of flubendiamide declined below detectable level of 0.01 mg kg(-1) after 5 and 7 days of application at lower and higher dose with RL(50) of 0.72 and 1.32 days, respectively. Thiacloprid residues reached below its detectable level of 0.01 mg kg(-1) after 5 and 7 days of its lower and higher dose with RL(50) of 0.83 and 1.79 days, respectively.

Single basal application of thiacloprid for the integrated management of Meloidogyne incognita and Bemisia tabaci in tomato crops

“…This may be because thiacloprid dissipates slower in the soil than on the plant20. Thiacloprid would be gradually released from the soil and absorbed into the roots, thus persisting longer as reported for imidacloprid21.…”

Influence of compost of sewage sludge and low-quality water on pesticide uptake by tomato plants grown in an iron mine soil

“…The concentration of FEN fell between 32 and 33 %, indicating a much faster metabolism in tomato for THC than for FEN. Previous studies with tomato established THC half-life in 2-7 days (Omirou et al 2009;Kooner et al 2010;Sharma and Parihar 2013), while in cabbage it ranged between 1.3 and 1.6 days (Wang et al 2011) and in eggplant the t 1/2 raised to 11-12 days, being dissipation rate independent of the applied dose (Saimandir et al 2009). Residues of FEN in tomato were not detectable after 3 or 7 days (Cabras et al 1985;Cabizza et al 2012) pointing to a rapid degradation rate, which is not in accordance with our results.…”
