  • Spreading Active Agricultural Agents
    Publication number: 20120270942
    Abstract: Disclosed herein is a device for the application of agricultural active agents, wherein the device is suitable to be brought to the site of action in a manner temporally and spatially separated from the production process, and comprises a dispenser and non-water-soluble nanofibers and/or mesofibers charged with agricultural active agents. The polymers from which the nanofibers and/or mesofibers are made are preferably biodegradable. The agricultural active agents are selected from fungicides, herbicides, batericides, plant growth regulators and plant nutrients. These are preferably pheromones, kairomones and signaling substances. Furthermore, a method for the production of this device is disclosed, wherein the nanofibers and/or mesofibers charged with active agents are produced via electrospinning. The device is suitable to be used to bring agricultural active agents to the site of action in a manner temporally and spatially separated from the production of this device.
