Plant plasters: Efficient spray micro-coatings for plant delivery

This proposal will study and apply recently-discovered methods of strongly attaching beneficial chemicals to plant leaves, stalks, and fruit. The materials have an unusually good ability to stick to crop plants and deliver herbicide or pesticide active ingredients more efficiently than standard additives, without toxicity. Recent findings have shown significant health risks from commercial herbicide additives and their run-off into vulnerable ecosystems like the Great Barrier Reef. This project will explain the unusually effective, but simple, adhesion and delivery performance, incorporate the new additives into commercially-relevant formulations for our industrial partner, and work to deliver the materials at relevant manufacturing scales.
