In this poster we present a novel systemic insecticide based on imidazoline and thiazoline chemistry. Optimising the formulation, including a classical adjuvant evaluation as well as the preparation of specific salts failed to improve aphicidal activity on whole plant bioassays. To evaluate leaf uptake in the absence of plant physiology, we developed a new method which allowed for the first time the direct, quantitative and real time translation of diffusion kinetics across leaf cuticular membranes into biological effect. Benefits and limitations of this new assay will be discussed.
