Gesellschaft für Phytopathologie mbH Konstanz

For more than 20 years of research in the field of plant protection and microbiology.

Screening and development of biotechnological production processes (fermentation and formulation)

The research by the company Bio-Protect is based on preliminary scientific work by the chair of Phytopathology at the University of Constance, which was dealing with the isolation and characterization of antagonistic yeastlike fungi. The idea arose of colonizing the habitat on the plant or fruit at an early stage with these harmless yeasts and thus preventing infection by harmful microorganisms (fungi or bacteria).

The company Bio-Protect continued this research approach and has already developed the following powerful preparations: Boni Protect to control storage decay in pome fruit, Blossom Protect to combat fire blight and Botector to combat grey mould (Botrytis spp.) in strawberries and wine. These preparations contain two strains of the yeast-like fungus Aureobasidium pullulans. Bio-Protect GmbH has developed production procedures for both the antagonist strains and appropriate formulations for their use in the different indications.

These products have been registered in many countries within and outside of Europe by bio-ferm GmbH from Austria, and are already being marketed worldwide. Driven by the know-how gathered over years, we have set ourselves the goal of developing further biotechnological plant protection products. The first goal here was to combat oomycetes such as downy mildew fungi or Phytophthora infestans. Thereby the research project “Use of microorganism for copper reduction in combating late blight and downy mildew (oomycetes) in organic farming ” sponsored by the German Federal Environmental Foundation, the additive 2H13 was developed.


In the joint research project mikroPraep we develope, together with Hochschule Geisenheim University, JKI Federal Research Centre for Cultivated Plants and the TU Berlin, a broad range fungicide based on microorganism. This project is funded by the Landwirtschaftlichen Rentenbank.
