| 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... |

| Die Netzfleckenkrankheit der Gerste (Drechslera teres) ist eine wichtige samenbürtige Krankheit im der ökologischen Sommergerstenproduktion. Einige wirksame Saatgutbehandlungen für die ökologische Landwirtschaft wurden bereits gefunden. Essigsäure als neue Saatgutbehandlung war die wirksamste Behandlung in den Versuchen, die von 2007 bis 2009 stattfanden. Die Reduzierung der Wassermenge von 4 auf 2 Liter pro 100 kg Saatgut in der Ethanol-Behandlung (70%)führte zu einer geringeren Wirkung. Diese Wirkung konnte durch den Einsatz von Haftmitteln nicht verbessert werden. Die Methode der Ethanol-Behandlung hatte eine sichtbare Wirkung auf den Krankheitsbefall. Saatgut, das direkt nach der Behandlung getrocknet wurde, zeigte einen höheren Befall mit Netzflecken... |
