20150366190 | Sustained Release Methods to Defeat Plant Pests - A dilute concentrate for treating vegetation for suppressing fungi thereon, formed from a concentrate having components added in the following sequence fungicide, EtOH, and surfactant, at about 1:3:1 weight percent, respectively, and forming supramolecular assemblies comprising surfactant/fungicide/EtOH, surfactant/fungicide, and free non-associated fungicide; and a latex/water solution, wherein the supramolecular assemblies in the dilute concentrate now include latex/fungicide/surfactant, latex/fungicide, and free fungicide. Upon drying of a latex film from the dilute concentrate supramolecular assemblies, the composition of the assemblies regulates the release of fungicide from the dried latex film by the formation of active pools with varying water solubility, wherein the surfactant forms supramolecule assemblies with the fungicide via a non-covalent mechanism to produce (i) a composite surfactant/fungicide combination, a fraction of which assembles with the polymerizing latex via a non-covalent mechanism to form additional supramolecular assemblies and (ii) a fungicide/latex combination that is formed by a non-covalent mechanism. | 12-24-2015 |
