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... |

Damages of planted seed and emerged seedlings caused by birds represent a significant problem in organic farming since there is no chemical repellent available. Bird attack often leads to reduced emergence and yield decrease. In the course of a perennial cooperation project 30 different plant extracts were systematically checked on the ability to prevent bird damage. Corn seed was applied with different extracts and tested via choice trials (seed and seedling) in aviaries. This screening resulted in detection of repellent effective extracts, whereby combined application of several extracts increased the positive activity. Accompanying tests showed no negative impacts of the extract application on seed quality (germination, vigour). First field trials... |

Until now, the term ‘Farming for Health’ is unknown in Germany but it would cover a wide spectrum of different kinds of social agriculture already existing in Germany, such as farms that integrate disabled people or drug therapy into their farming system, or farms that integrate children, pupils or older people. Relevant work in Germany is done in ‘Sheltered Workshops’, where supporting and healing powers of farming and gardening are used for disabled people with a diversity of work possibilities. Relevant activities also take place in work-therapy departments using horticultural therapy and in animalassisted therapy. There are an estimated number of 1000 different projects for mentally ill, disabled and elderly people in hospitals, Sheltered Workshops, on... |
