Summary

In 2001 eleven different apple scab control strategies with reduced copper use and copper substitutes were tested on an organic apple orchard near Hamburg, Germany. The strategies were tested on a six year old "Elstar" plantation. Among the different fungicides were copper sulphate, copper hydroxide, lime sulphur, sulphur, bacillus subtilis and "Biofa-Algenextrakt".
The results show that fruit scab as well as leave scab can be fairly well controlled by a lime sulphur strategy and the copper hydroxid strategies. Bad results were produced with the different copper sulphate strategies and bacillus subtilis, insufficient results with the sulphur strategies.
