    • 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. The application is suitable to be carried out mechanically or automatically. This is preferably agricultural land used for fruit growing, viticulture, gardening or a commercial row crop. The device according to the present invention is particularly suitable to be used for the regulation of arthropods.

    • The invention relates to a non-viral transfection agent comprising polymer/nucleic acid complexes and nanofibers, wherein the polymer/nucleic acid complexes are composed of at least one nucleic acid and at least one cationic polymer. The nanofibers carry the polymer/nucleic acid complexes, wherein the non-viral transfection agent is advantageously produced by means of electrospinning. The cationic polymer is favorably a polyimine or polyethyleneimine and can be modified with one or more hydrophilic polymers coupled thereto. It can also be advantageous to couple the cationic polymer with one or more carbohydrates and/or with a receptor-specific ligand. The nucleic acid is a DNA or an RNA, or a DNA or RNA derivative, advantageously a therapeutically active nucleic acid. The nanofibers are composed of biodegradable, biocompatible polymers. The nanofibers or the entire transfection agent can be provided with a polymer coating. A method for producing a non-viral transfection agent comprises the following steps: providing the polymer/nucleic acid complex, producing a spinning solution containing the polymer/nucleic acid complexes, and electrospinning.
