Zusammenfassung

Protective sprays with copper are included in spray schedules for apple scab control in organic fruit growing although the use of copper is under discussion. In a research project, funded by the ”Bundesprogramm Ökologischer Landbau” biocontrol agents have been screened for their efficacy against apple scab (Venturia inaequalis) to find alternatives to copper. In greenhouse trials we tested biocontrol agents for their protective and curative efficiency against apple scab by artificial inoculation of potted apple trees. Applications were done 18 hrs before inoculation, 5 hrs after inoculation during simulated rain fall, 24 hrs or 48 hrs after inoculation. In addition, the efficacy of protective applications followed by simulated rain was tested. 23 biocontrol agents and 12 combinations of at least two biocontrol agents were involved in the tests. The optimal moment of application differed between the preparations tested. Sulphur and copper products had the highest efficiency when tested protectively. Some additives (e.g. NuFilm P, T/S forte) enhanced the rain fastness of protective sulphur fungicides. Five preparations reached their highest activity when sprayed curatively 24 hours after inoculation. The products with the highest curative efficiency are based on carbonates. Several combinations of preparations were found, which revealed a high efficiency against apple scab between 18 hrs before and 24 hrs after inoculation. The biocontrol agents and combinations with the highest efficacy will be tested in field trials within this BÖL-project.
