Management of cereal and oilseed crop diseases in Norway Andrea Ficke
Overview: Azoxystrobin sensitivity in glume blotch population (lab studies) Field performance of different fungicides DSS and the models in use Site-specific disease control
Azoxystrobin sensitivity in S. nodorum isolates
Azoxystrobin sensitivity in S. nodorum 2011 2013
Azoxystrobin sensitivity in S. nodorum: Strong variation in sensitivity present No major shifts between 2011 and 2013, Less use of pesticides with single type of action ?

DSS and the models in use….
X The models Leaf blotch in summer and winter wheat Net blotch in barley Scald in barley Mycotoxins (DON) in wheat X Flowering model in oats
Summer wheat/ winter wheat: Leaf blotch diseases Based on Danish model Driving factor: precipitation Input data: variety, tillage, spray info, sowing date, weather station
Recommended fungicide timing based on economic threshold Output: Recommended fungicide timing based on economic threshold But how to calculate economic return? Yield quality and quantity loss
Site specific disease control ‘The Multisens project’ Fertilization Weed control Disease management N2O measurements
Early disease detection using remote sensors
Volatile organic compound collection
Thank you!
