Development of a systems approach for the management of late blight (Phytophthoi infestans) in organic potato production: an update on the EU Blight-MOP project

摘要

The recent tightening of EU restrictions on the use of copper fungicides in organic production systems has increased the potential for devastation by late blight of potato (caused by Phytophthora infestans). The EU project, Blight MOP, is an attempt to introduce a 'system approach' to late blight management into organic production: integrating agronomic strategies, resistant varieties, diversification strategies and alternative treatments. An overview of the project is given, along with preliminary results from 2001.
