Dissipation pattern of flubendiamide 480% SC in Dolichos bean

Abstract

Field and laboratory experiments were conducted during kharif, 2015 to study the dissipation pattern of Flubendiamide 480% SC @ 60 g a.i ha-1 by spraying thrice on field bean collecting samples at regular intervals i.e. 0, 1, 3, 5, 7, 10 and 15days after last spray and analyzed. The results of flubendiamide residues showed that, the initial deposits of 1.79 mg kg-1 were detected on field bean pods. The residues recorded at 1, 3, 5 and 7th day after third spraying were found to be 0.90, 0.51, 0.13 and 0.06 mg kg-1, respectively and showing a dissipation per cent of 49.72, 71.51, 92.74 and 96.65 per cent, respectively. The residues were below detectable level (BDL) after ten days showing hundred per cent dissipation.
