The present invention is in the field of aqueous emulsions that dry into water-insoluble or water-resistant structures that are useful for active packaging, manufactured devices and components, and other applications. The aqueous emulsions of the present invention comprise biopolymers, metal in the form of a salt, nanoparticles or metal oxide nanoparticles, essential oil, and additives such as surfactants and plasticizers. When the components of the emulsion are mixed following the distinctive method of preparation, a water-soluble fluid is obtained, which, upon drying, becomes a water-insoluble or water-resistant solid exhibiting antimicrobial, antioxidative, and other useful properties including tensile strength, elasticity, transparency. The obtained fluid may be applied by spraying, pouring, injecting, 3-D printing, or otherwise formed into a solid product of any geometrical shape including film, foil, or other 3-D shape.

A first aspect of the invention is an agricultural composition comprising nanoparticles, an agrochemical active ingredient in the nanoparticles, and optionally (but in some embodiments preferably) a carrier for the nanoparticles. In some embodiments, the nanoparticles are viral particles or capsids, particularly plant viral particles or capsids. In some embodiments, the carrier comprises an inert or biodegradable carrier (e.g., a solid carrier) to which the nanoparticles are bound or in which the nanoparticles are suspended. In some embodiments, the carrier comprises inert or biodegradable polymer fibers.

Stabilized liquid agrochemical compositions are provided that comprise flowable, aqueous dispersion concentrates comprising a) a continuous aqueous liquid phase; b) at least one dispersed, solid phase comprising a dispersion of polymer particles having a mean particle size of at least one micron, wherein the outside surfaces of the particles comprise a colloidal solid material and wherein the particles have at least one agrochemically active ingredient distributed therein, optionally a non-porous particulate mineral that acts as a diffusion barrier to slow the release of the active ingredient, and optionally at least one non-cross-linkable mobile chemical such that the extraction of this chemical from the disperse phase renders it porous in a manner that allows the active ingredient to diffuse out. The colloidal solid is used to stabilize the polymerizable resin in an emulsion state during preparation. In one embodiment, the agrochemically active ingredient is a solid and is distributed within the dispersed solid phase or is a liquid and is distributed within the dispersed solid phase. The compositions of the invention can be used directly or with dilution to combat pests or as plant growth regulators.
