    Most agricultural products are designed to be applied as uniform dispersions in aqueous spray solutions. The quality of this dispersed system is highly important for successful biological control.

    For the evaluation of the dispersion stage, a new test-system was developed. It is based on a fiber optic photometric sensor system. It allows one to characterise and describe the dynamics of a dispersion of a product in a spray tank, settling over time, redispersion properties, and thus the differentiation of products. Examples for performance and evaluation of typical agrochemical products are presented.
