ABSTRACT

In agricultural practices, adjuvants are mixed with pesticide formulations in the spray tank solution. Four commonly used surfactants for cropping were evaluated for their influence on spray performance. In a spray test, the volume median diameter, Dv 0.5 (the volume percentage of droplets below 100 μm and the relative span value), was analyzed for a range of nozzles. When using different adjuvants, a totally different Dv 0.5 was sometimes obtained, compared to spraying pure water. The concentration of these adjuvants plays an important role. Increasing the pressure resulted in a decrease of droplet size. At a pressure of 3 bar, the intensity of the effects of the adjuvants was similar to that at a pressure of 2 bar. When the reduction in surface tension is taken into consideration to explain the droplet behavior in spray performance, it can be concluded that a logical relationship is not always found, and that the type of nozzle in use should always be considered.
