Abstract :
[en] Spray retention is a critical stage in pesticide application since non-retained drops can result
in reduced efficacy, economic loss and environmental contamination. Current methods of
retention assessment are based either on field experiments or laboratory studies. The former
are usually performed on whole plants under realistic spray application conditions but offer
no insight into the physics behind the process whilst the latter mainly focus on drop impact
physics but are usually restricted to unrealistically low drop speeds. The aim of the paper is
to devise an experimental method to investigate retention at drop scale level as a function of
operational parameters but under controlled realistic conditions. A device based on highspeed
video was developed to study retention on a synthetic superhydrophobic surface for
a moving agricultural nozzle. The sizes and velocities of the drops generated were measured
immediately before impact using image analysis. Impact class proportions were established
and transition boundaries between impact outcomes were quantified using Weber number.
Two contrasting experiments were performed to investigate the ability of method to detect
small parametric changes. The insignificant changes in spray pattern that occur from
pressure changes, did not significantly affect impact class boundaries, but changed the
proportion of drops in each class because of size and velocity variations. The use of
a surfactant reduced the volume median diameter of the spray, increased impact speed and
changed the impact class boundaries. The method should allow a precise parametric
investigation of spray retention in laboratory and close to field conditions.
