title: Persistence and dissipation of flubendiamide and des-iodo flubendiamide in cabbage (Brassica oleracea Linne) and soil.
abstract: Flubendiamide belongs to a novel class of insecticide which controls lepidopteran pest complex of cabbage such as diamondback moth, cabbage white butterfly, cluster caterpillar etc. Being a newly introduced insecticide no information is available on its residue persistence in cabbage. A study was undertaken to evaluate the residue persistence of flubendiamide in cabbage and soil following 2 applications of flubendiamide 480 SC at the recommended and double the recommended dose of 24 and 48 g a.i. ha(-1). Initial residue deposits of flubendiamide in cabbage were 0.33 and 0.49 mg kg(-1) respectively. The residues persisted for 10 days from the both the treatments and dissipated with the half-life of 3.9 and 4.45 days, respectively. Des-iodo flubendiamide, a metabolite of flubendiamide, was not detected in cabbage at any time during the study period. Soil sample collected from the treated field after 15 days was free from any residue of flubendiamide or its metabolite.
