1. A method of analyzing an adjuvant for reducing bag rupture in an agricultural spray containing the adjuvant, the method comprising:
dispensing from a nozzle the agricultural spray containing the adjuvant;
detecting one or more bags rupturing from an initial spray pattern of the agricultural spray, the one or more bags comprising a thin membraned semi-spherical protrusion extending from the agricultural spray, the initial spray pattern being a region of the agricultural spray initially exiting the nozzle that forms a continuous sheet-like portion; and
determining whether the agricultural spray exhibits fewer fine droplets formed by the one or more bags rupturing from the initial spray pattern.
