A polyacrylamide-based composition as a microemulsion is provided in the form of a water-in-oil microemulsion with polyacrylamide dissolved in the water phase, and further comprising ethylene oxide - propylene oxide block copolymer. Specifically, the present invention includes, dissolved in the water phase, a polyacrylamide copolymer and an EO/PO block copolymer, with the water phase mixed with an oil phase. Preferably, the present invention may further comprise the presence of at least one fatty acid and/or at least one nonionic surfactant to stabilize the microemulsion. In addition, the present invention may further comprise effective amount of other components, such as pesticides and/or fertilizers, that may be delivered to trees, plants or other vegetation. |
