Dissipation and transformation of the diamide insecticide cyantraniliprole in ornamental snapdragon (Antirrhinum majus)

Dissipation and transformation of cyantraniliprole, a new diamide class insecticides, were investigated under greenhouse conditions, using snapdragon (Antirrhinum majus) as the model plant. cyantraniliprole in treated leaves was found to be dependent upon application methods (foliar spray versus soil drench) doses (high low dose), with parent insecticide being major residue at various sampling points. A high-dose foliar resulted pesticide 6.7–23.8 μg/g fresh weight over 8 weeks treatments, while drench treatment varied from 0.8 1.4 μg/g. However, contents similar between two dose. The pathways primarily intramolecular rearrangements, IN-J9Z38 metabolite across treatments. Several other metabolites also identified, some which unique methods. Out total 26 tentatively identified this study, 10 application, six drench. In addition plant-mediated biotransformation, photodegradation compound potential mechanism application.
