Abstract
A method to reduce bag rupture in a spray dispensed from a nozzle involves detecting one or more bags rupturing from an initial spray pattern of the spray dispensed from the nozzle, the one or more bags comprising a thin membraned semi-spherical protrusion extending from the spray, where the initial spray pattern is a region of the spray initially exiting the nozzle that forms a continuous sheet-like portion. The spray includes an agricultural spray including water, at least one polymer, and at least one perforation-aid type adjuvant. The agricultural spray exhibits fewer fine droplets exhibiting a diameter less than about 150 μm formed via the bag rupture approach to droplet formation.
