COMPARISON OF THE ´COUGARBLIGHT´ AND ´MARYBLYT´ FORECASTING SYSTEMS IN THE PROVINCE OF REGGIO EMILIA (ITALY)

After the appearance of fire blight in the Reggio Emilia province, the Consorzio Fitosanitario Provinciale set up a long-term project for the control of the disease.
Forecasting systems, previously developed in other countries affected by the disease, were used to detect periods with high risk of infection.
A comparison was made of the forecasting systems “Cougarblight” and “Maryblyt”, to determine the best environment for the use of each model.
Three farms with a total of 10 ha were evaluated in the Correggio area (Reggio Emilia). Weekly inspections were carried out during the spring and summer months of 2002 and 2003 to identify shoot and blossom infections, and active cankers on wood.
An automatic regional weather station located in the area was used to provide meteorological data for the forecast systems.
This paper discusses the differences observed between the two models as regards the accuracy of infection forecasting in the field and their possible application in other areas.
