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.

Methods of using drift reduction adjuvant compositions

Reducing fines from an agricultural spray dispensed from a nozzle is provided in the disclosed methods. The agricultural spray comprises water, an agricultural composition such as a pesticide, at least one oil emulsion drift reduction adjuvant, and at least one spontaneous emulsion drift reduction adjuvant. The agricultural spray exhibits fewer fine droplets having a diameter less than about 105 μm, about 150 μm, and/or about 210 μm compared to an agricultural spray neither or only one of the oil emulsion drift reduction adjuvant and the spontaneous emulsion drift reduction adjuvant.

Drift reduction adjuvants and methods of using the same

In an embodiment, a test section comprises at least one surface defining an at least partially enclosed space. The at least partially enclosed space defines an airflow path for air to flow. The test section also comprises a nozzle disposed in the at least partially enclosed space. The nozzle is configured to spray an agricultural spray and is positioned to emit the agricultural spray such that at least a section of the agricultural spray exhibits a non-parallel angle relative to the airflow path defined by the at least partially enclosed space. The test section further comprises at least one stimulus source positioned to illuminate at least a portion of the agricultural spray adjacent to the nozzle. Additionally, the test section comprises at least one detector positioned to image at least the portion of the agricultural spray adjacent to the nozzle.
