Additionally, the disclosures describes application to various plants and pests as well as advantages of the disclosed formulations.

Pyrethroid formulations

The present disclosure describes a formulation comprising a nanoparticle including a polymer-associated herbicide, such as fenoxaprop or pyroxsulam with an average diameter of between about 1 nm and about 500 nm; wherein the polymer is a polyelectrolyte and a dispersant or a wetting agent. The disclosure describes various formulations and formulating agents that can be included in the formulations.

Herbicide formulations

In various aspects provided are methods for producing a nanoparticle within a cross-linked, collapsed polymeric material, said method including (a) providing a polymeric solution comprising a polymeric material; (b) collapsing at least a portion of the polymeric material about one or more precursor moieties; (c) cross-linking the polymeric material; (d) modifying at least a portion of said precursor moieties to form one or more nanoparticles and thereby forming a composite nanoparticle. In various embodiments, a non-confined nanoparticle can be produced by complete pyrolysis of the confined nanoparticle, and a carbon-coated nanoparticle by incomplete pyrolysis of the confined nanoparticle.

Composite nanoparticles, nanoparticles and methods for producing same

Composite nanoparticles containing organic ions

A method for producing a composite nanoparticle, including the steps of: changing the conformation of a dissolved polyelectrolyte polymer from a first extended conformation to a more compact conformation by changing a solution condition so that at least a portion of the polyelectrolyte polymer is associated with a precursor moiety to form a composite precursor moiety with a mean diameter in the range between about 1 nm and about 100 nm; and cross-linking the polyelectrolyte polymer of the composite precursor moiety to form a composite nanoparticle.

Producing composite nanoparticles

A method for producing a composite nanoparticle, including the steps of, collapsing at least a portion of a polyelectrolyte polymer in solution about one or more precursor moieties to form a composite precursor moiety having a mean diameter in the range between about 1 nm and about 100 nm, wherein the polyelectrolyte polymer has an extended conformation in a first solution state and a more compact conformation in a second solution state; and cross-linking the polyelectrolyte polymer of the composite precursor moiety to form a composite nanoparticle wherein the precursory moiety is a charged organic ion.
