Primary attack Foulum, 1988
Milder winters - Volunteer plant 2015, Foulum
Sexual recombination = high diversity / adaptation + oospores Earlier attacks, most likely from oospores Early attacks on resistant starch potatoes (e.g. Kuras) More aggressive isolates (Blu-13), fungicide resistans ”False crop rotations” due to volunteers survival during winter Structural changes in agriculture (less farmers with more fields)
Oospores 2014 Denmark, Foulum
>1997
Increased fungicide use, from 5 in 1990th to 10 in 2010-15
The enemy (Denmark)

Defence weapons Primary attack Volunteers Dumps Oospores
• Healthy seed and crop rotation • Breeding & inclusion of new resistance genes • DSS and control strategies (Fungicides: timing, type og dosis) • Mapping of the pathogen on population level. Link between genotype and phenotype • Surveillance (Scouts: when and where is the disease, how much, disease activity etc.) • Strategic, tactical and operational planning and missions
