“…2), this will in effect lower the mass of active per unit area without any change in concentration until the spray solution begins to evaporate. In any case, there will be a ''solution residue'' where the concentration of the active is many times more than in the starting spray solution (Zabkiewicz 2003).…”

Pesticide efficacy is improved by surfactants. Increase in the foliar uptake is particularly useful for herbicides, growth regulators and defoliants, because less active compounds are needed, thus decreasing cost and pollution. Therefore, the choice of the adjuvant in an agrochemical formulation is crucial. The surfactants commonly used as adjuvants include anionic, non-ionic, amphoteric and cationic surfactants. This review analyses the role and properties of the new adjuvants for agriculture and the improvement of the ecotoxicity profile of the pesticide formulations in glyphosate formulation.

The physico-chemical properties of the spray liquid affect the efficiency and effectiveness of crop protection treatments. A measure of leaf wettability is the wetting angle, the testing of which is neglected in routinely performed spraying. In the search for a method useful for determining leaf wetting angle for crop protection treatments, the method that Bikerman (1941) applied to the surface of the object observed from above was evaluated. The assumptions of the method and the resulting opportunities and constraints in its application are presented in this paper. The influence of leaf, liquid and droplet properties on the wetting angle was discussed. It was concluded that Bikerman’s method is suitable for determining leaf wetting angles over a wide range of physical properties of liquids used in crop protection treatments.

“…Finally, it should be noted that spray application is a relatively inefficient delivery process16, 17 where less than 1% of the applied compound may actually reach the required site of action. There are many factors that cause losses, including spray drift and evaporation,18, 19 rebound of drops from waxy leaf surfaces20 and poor retention and runoff 21, 22.…”
