Summary

The intention of this research project, which was supported within the "Bundesprogramm Ökologischer
Landbau", was to look for alternatives in organic fruit growing to control apple scab, Venturia
inaequalis. One important part of the investigations was the application of different substances like
microbiological nutrient media, enzymes usually used for production of fruit juices and organic fertilizers
on their effect on the ascospore potential on depots of fallen leaves. Some substances like
TRYPTIC SOY BROTH increased the decomposition of the leaves significantly, other like BACTOFIL B
and HUMOFIX showed nearly no effect on the decomposition, but reduced the ascospore potential in
early spring by 80 % compared to the untreated control.
