Abstract

An additive concentrate modifies droplet size of an aqueous agricultural composition upon spraying. The additive concentrate includes water and a cross-linked polymer formed from a polyvinyl alcohol and a borate. The additive concentrate includes a polyvinyl alcohol moiety in an amount of from 0.005 to 10 weight percent and a borate moiety in an amount of from 0.001 to 5 weight percent, based on a total weight of the additive concentrate. The cross-linked polymer is independently dispersed in the water. A method of spraying an aqueous agricultural composition through a spray nozzle onto a plant is also provided. The aqueous agricultural composition includes an active ingredient and the additive concentrate. Spraying the aqueous agricultural composition produces spray droplets having an average diameter that is larger than an average diameter of spray droplets produced from spraying a control composition that is free of the cross-linked polymer, as evaluated using ASTM E2798-11.
