Cuticle spray deposits

Several key factors may be identified in the uptake activation process (1) In the spray droplet, (2) in the deposit formed on the leaf surface, (3) in the cuticle before or during penetration and (4) in tissues underlying the site of application. Four main sites were considered by Stock and Holloway [125] for increasing the uptake of the agrochemical into a leaf (1) Surface of the cuticle (2) within the cuticle itself, (3) the outer epidermal wall underneath the cuticle and (4) the cell membrane of internal tissues.
