Thiamethoxam can be absorbed by the leaves and crowns of the plant, it is therefore important to apply in a high volume application and watering the product in as soon as possible (the target pest is soil borne). Absorbtion through roots, after application to the root zone, normally happens over time and is facilitated by soil moisture. It is transported acropetally (upwards) in the xylem. This systemic translocation contributes to even distribution of the active ingredient within the plant tissue. Bio-availability of soil insecticides is very important to ensure high standard efficacy in all soil moisture conditions.
