Organic EprintsContributions of EU-project REPCO to apple scab controlJürgenKöhlauthorBartHeijneauthorJohnHockenhullauthorHanneLindhard PedersenauthorMarcTrapmannauthorUteEibenauthorLuciusTammauthorThe objective of REPCO is to contribute to the replacement of copper fungicides in organic agriculture by new measures for control of downy mildew (Plasmopara viticola) in grapevine and scab (Venturia inaequalis) in apple. Both major European organic crops strongly depend on copper fungicides. Permitted amounts will be reduced stepwise during the following years (Council Regulation (EEC) 2092/91, Annex II) to avoid environmental risks. In European countries where copper fungicides are already out of use, production of organic apples suffers severe economical problems because of insufficient scab control. Potentiators of resistance, organically based fungicides and biocontrol agents are screened and evaluated in apple. Effects of crop management practices in organic agriculture on overwintering of Venturia inaequalis are assessed. Novel disease control measures and knowledge are integrated into organic management systems. 'Pipeline' products already under development elsewhere are included and where necessary optimised in their use.
