The ADEM system is a PC-based system and contains a disease forecasting model for Neonectria canker and fruit rot.
- The disease models are driven by the following weather variables – rainfall, surface wetness duration, ambient temperature and ambient relative humidity; these are recorded on a logger and downloaded to the PC.
- The models use the weather data to determine the favourability of the weather for Neonectria infection of fresh leaf scars and near-mature fruits and indicate the incidence of disease likely to occur at these two infection sites.
Forecast of fruit rot
- The model will be revised shortly to include new data on fruit susceptibility to Neonectria rot from recent inoculation experiments.
