Entwicklung von Verkapselungsmethoden für Pflanzenextrakte

Summary

Organic farming is reliant on alternative active substances like plant extracts for plant protection. Limited stability of plant extracts complicates their use and storage.
Consequently, there is a need for the development of novel formulations like encapsulation that stabilize the active substances, control their release and provide an
appropriate handling. In the project DevelOPAR (Development of a plant avian repellent) we illustrate how a repellent plant extract is formulated in order to be applied
as seed-coating protecting seeds not to be eaten by birds. Testing the methods of ionic gelation and complex coacervation we managed to encapsulate the plant extract
and produce homogenous particles that can be applied on corn seeds using a spin coating process.
