Placement of yellow water-sensitive papers within the canopy (left). Canopy has been divided into Upper (U) and Lower (L) sections, in the Outside (O) and Inside (I) leaf layers, and Abaxial (B) and Adaxial (D) leaf surface; acronyms of the yellow water-sensitive paper positions are: UOD − Upper part of the canopy, Outside leaf layer, aDaxial leaf surface, UOB − Upper part of the canopy, Outside leaf layer, aBaxial leaf surface, UID − Upper part of the canopy, Inside leaf layer, aDaxial leaf surface, UIB − Upper part of the canopy, Inside leaf layer, aBaxial leaf surface, LOD − Lower part of the canopy, Outside leaf layer, aDaxial leaf surface, LOB − Lower part of the canopy, Outside leaf layer, aBaxial leaf surface, LID − Lower part of the canopy, Inside leaf layer, aDaxial leaf surface, LIB − Lower part of the canopy, Inside leaf layer, aBaxial leaf surface. In the right section, classes of the spraying deposition according to the percentage of coverage are defined.
