Abstract: An additive comprising an active; the interfacial polymerization reaction product of a (poly)isocyanate and a polyamine; a copolymer having maleic anhydride-based repeat units and either or both of olefinic or styrenic-based repeat units; wherein at least a portion of the maleic anhydride-based repeat units are neutralized. A method of preparing an additive comprising providing an oil phase comprising an active, a solvent, a (poly)isocyanate; providing an aqueous phase comprising water and an emulsifier; mixing the oil phase and the aqueous phase to provide an emulsion; providing a polyamine to the emulsion; providing an aqueous dispersion or solution comprising a copolymer having maleic anhydride-based repeat units and either or both of olefinic or styrenic-based repeat units; wherein at least a portion of the maleic anhydride-based repeat units are neutralized; and cofeeding the emulsion and the aqueous dispersion or solution to a spray dryer.

Abstract: Disclosed is a composition comprising an agricultural active ingredient that is water insoluble or poorly soluble in water; a polyalkoxylated alcohol having the formula R—O(AO)—H where R is a alkyl, alkenyl, aryl, aralkyl, or heterocyclic group having 1-25 carbons and where AO is a polyoxyalkylene chain having “m” oxyalkylene groups having four to 10 carbon atoms oxybutylene (HAO) and “n” oxyethylene (EO) groups, where m is at least 1, n is at least 2, and m+n is no more than 200; and either water, a solvent which is at least partially miscible with water, or both. Also disclosed is a method of using the composition to control pests by spraying.

Abstract: An additive consisting of an active, the active consisting of one or both of tetraacetylethylenediamine or triacetylethylenediamine; and the interfacial polymerization reaction product of a (poly)isocyanate and a polyamine. A method of preparing a water dilution-responsive additive comprising providing an oil phase comprising an active, a solvent, a (poly)isocyanate; providing an aqueous phase comprising water and an emulsifier; mixing the oil phase and the aqueous phase to provide an emulsion; providing a polyamine to the emulsion.
