Summary

In organically cultivated orchards of the LVWO Weinsberg in the years 2006 and 2007
trials were carried out about new products and their efficacy against apple scab. In the
year 2006 (variety ‘Gala’) Armicarb and BioPluss sprayed preventively during primary
ascospore season could not convince, also not in combination with lime sulphur as stopapplication.
Armicarb showed at ‘Gala’ a tendency to increase russetting of the fruits. In
the year 2007 (Variety ‘Elstar’) different combinations of wetting sulphur with yuccasaponin
and stop-applications (lime sulphur, Armicarb) were tested with focus on the time
immediately after blossom. The effect of Armicarb as stop-application was weaker than of
lime sulphur at an infection-period with extreme high ascospore potential. The differences
between the tested combinations were low. Wetting sulphur+yucca-saponin showed
interesting tendencies in the year 2007, but should not be combined with lime sulphur as
stop-application because of significantly increased reticular russetting of the apples.
