| In Europe, late blight, caused by Phytophthora infestans, is the most devastating disease affecting organic (and conventional) potato production. Under suitable environmental conditions the disease can spread rapidly and it can cause complete crop loss. The extent of damage due to late blight depends on several factors: in organic production systems these factors include climate, choice of variety, soil management and use of crop protection agents such as copper. Therefore, the extent of economic damage varies between European regions. Council Regulation (EEC) No 2092/91, amended by Commission Regulation (EC) No 473/2002 of 15 March 2002 regulates the use of copper in organic agriculture. Copper has been the single most important control agent in... |

| Problemstellung/Ziele Die Kraut- und Knollenfäule (Phytophthora infestans) ist die Krankheit, die im biologischen (aber auch konventionellen) Kartoffelanbau in Europa die größten Probleme verursacht. Unter günstigen klimatischen Bedingungen breitet sich die Krankheit sehr rasch aus und kann große Ertragsausfälle verursachen. Innerhalb von Europa variiert der durch P. infestans verursachte wirtschaftliche Schaden stark zwischen den Regionen. Dies hängt von verschiedenen Faktoren ab, aber in biologisch bewirtschafteten Anbausystemen immt man an, dass die klimatischen Bedingungen, die verwendeten Sorten sowie die agronomischen Maßnahmen wie Bodenbearbeitung oder die Verwendung von Pflanzenschutzmitteln eine wichtige Rolle spielen. Die Reduktion oder das... |

The extent of damage due to late blight depends on several factors: in organic production systems these factors include climate, choice of variety, soil management and use of crop protection agents such as copper. Therefore, the extent of economic damage varies between European regions. This report presents the results of a detailed survey that has been conducted in 7 European countries in the year 2001: (i) statistics on yields, farm gate prices, and production techniques, (ii) an analysis offarmer... |
