• ranged from 10.8° ± 7.3° to 31.3° ± 21.3° (Table 1). Wheat leaves are not vertically oriented to the plant axis. TAs provide information on droplet adhesion on such inclined surfaces. For wheat leaves, we could not find any comparative values for TAs in the literature. In the context of active ingredient

• hairs on the leaves. Agnique® SBO10 and the nonionic surfactant XP ED 75 increased the droplet adhesion and caused an increase of the TA from 20.9° to 85° and 90°, respectively. Scanning electron microscopy showed that surfactants with a hydrophilic–lipophilic balance value below 10 caused a size

• roll off. Droplet adhesion can be improved by adding adjuvants, such as surfactants. Surfactants enhance the leaf surface wettability by reduction of the surface tension of applied liquids. Surfactants are amphiphilic molecules with a nonpolar, hydrophobic structural group together with a hydrophilic
