A NATIONAL DISEASE FORECASTING SYSTEM FOR APPLE BLACK SPOT (VENTURIA INAEQUALIS) IN NEW ZEALAND |
| Authors: | R.M. Beresford, M. Spink |
| Abstract:
A weather information system has been developed which uses monitored and forecast weather to provide apple growers with precise information about the risk of spring ascospore infection by V. inaequalis. The system uses surface wetness, temperature and rainfall data, retrieved by telephone modem from a network of data loggers, to assess the risk of infection from recent wet periods, allowing optimum timing of curative fungicides. Forecasts of rain probability for the next 4 days are used to delay the application of routine protectant fungicides when rain is unlikely. | |
