An agricultural formulation includes a copolymer including (i) 20 wt % to 50 wt % monomeric structural units derived from a first acrylic monomer with a log Kow of 1.0 or less based on a total weight of the copolymer and (ii) from 50 wt % to 80 wt % of monomeric structural units derived from a second acrylic monomer with a log Kow of from 2.0 to 6.0 based on a total weight of the copolymer. The agricultural formulation also includes an active ingredient with a log Kow of greater than 1.0.
