Claims7
A composition comprising a polymer nanoparticle and at least one organic, neutral, non-ionic agricultural compound associated with the polymer nanoparticle, wherein the polymer nanoparticle is less than 100 nm in diameter and cross-linked;
- wherein the polymer nanoparticle comprises a collapsed water-soluble polyelectrolyte;
- wherein the polymer has a molecular weight of at least about 100,000 Dalton prior to collapse and cross-linking;
- and wherein the at least one organic, neutral, non-ionic agricultural compound is selected from the group consisting of a pyrethroid, a neonicotinoid, and combinations thereof.
A composition comprising a polymer nanoparticle and a combination of at least two organic, neutral, non-ionic agricultural compounds associated with the polymer nanoparticle, wherein the polymer nanoparticle is less than 100 nm in diameter and cross-linked;
- wherein the polymer nanoparticle comprises a collapsed water-soluble polyelectrolyte;
- wherein the polymer has a molecular weight of at least about 100,000 Dalton prior to collapse and cross-linking;
- and wherein the combination of at least two organic, neutral, non-ionic agricultural compounds comprises a combination of an insecticide and a fungicide.
