1. A method of reducing bag rupture in an agricultural spray dispensed from a nozzle, the method comprising:
dispensing the agricultural spray from the nozzle, the agricultural spray comprising:
water;
at least one polymer; and
at least one perforation-aid type adjuvant,
wherein a portion of the agricultural spray initially exiting the nozzle that forms a continuous sheet-like portion defining an initial spray pattern exhibits fewer fine droplets exhibiting a diameter less than about 150 μm formed via the bag rupture approach to droplet formation than an initial spray pattern of a similar agricultural spray that does not comprise the at least one perforation-aid type adjuvant.
