Summary

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
(pheasants, crows) confirmed the aviaries results. Nevertheless long term effectiveness of the extracts in the field is still challenging. A new project (DevelOPAR)
was initiated to further improve extract formulation and application technology. Extensive field trials are scheduled.
