Methods of using drift reduction adjuvant compositions

A method to reduce bag rupture in an agricultural spray dispensed from a nozzle, the method comprising:

• dispensing the agricultural spray from the nozzle, the agricultural spray exhibiting a sheet-like shape, the agricultural spray comprising:
• water;
• at least one drift reduction adjuvant composition comprising at least one rheology modifier and at least one perforation-aid type adjuvant;
• and
• at least one agricultural composition comprising at least one pesticide and/or at least one fertilizer;
• wherein the agricultural spray exhibits fewer fine droplets exhibiting a diameter less than about 150 μm formed via the bag rupture approach to droplet formation than a similar agricultural spray that does not comprise the at least one perforation-aid type adjuvant as determined by an analysis of the agricultural spray;
• wherein the analysis of the agricultural spray comprises detecting at least a portion of the agricultural spray adjacent to the nozzle or a f such that one or more bags rupturing from the agricultural spray, if present, are detected, each of the one or more bags comprising a thin membraned semi-spherical protrusion extending from the agricultural spray, wherein the portion of the agricultural spray adjacent to the nozzle includes a region of the agricultural spray initially exiting the nozzle that forms a continuous sheet-like portion defining an initial spray pattern.

A method to reduce bag rupture in an agricultural spray dispensed from a flat-fan nozzle, the method comprising:

• dispensing the agricultural spray from the flat-fan nozzle in a direction that is perpendicular to a ground, the agricultural spray comprising:
• water;
• at least one rheology modifier comprising at least one of guar gum, modified guar gum, polyacrylamide, or lecithin;
• at least one perforation-aid type adjuvant comprising at least one surfactant and at least one of a modified seed oil or a paraffinic oil;
• and
• at least one agricultural composition comprising at least one pesticide and/or at least one fertilizer;
• wherein the agricultural spray exhibits at least 50% fewer fine droplets exhibiting a diameter less than about 150 μm formed via the bag rupture approach to droplet formation than a similar agricultural spray that does not comprise the at least one perforation-aid type adjuvant as determined by an analysis of the agricultural spray;
• wherein the analysis of the agricultural spray comprises detecting at least a portion of the agricultural spray adjacent to the nozzle or a similar nozzle such that one or more bags rupturing from the agricultural spray, if present, are detected, each of the one or more bags comprising a thin membraned semi-spherical protrusion extending from the agricultural spray, wherein the portion of the agricultural spray adjacent to the nozzle includes a region of the agricultural spray initially exiting the nozzle that forms a continuous sheet-like portion defining an initial spray pattern.
