Movement of cyantraniliprole in plants after foliar applications and its impact on the control of sucking and chewing insects.

Background: Given the physical properties of insecticides, there is often some movement of these compounds within crop plants following foliar application. In this context, movement of two formulations of cyantraniliprole, an anthranilic diamide, was characterized for translocation to new growth, distribution within a leaf and penetration through the leaf cuticle.

Results: Upward movement of cyantraniliprole to new plant growth via the xylem was confirmed using (14) C-radiolabeled cyantraniliprole and from Helicoverpa zea mortality on tomato leaves that had not been directly treated.
