A review of disease-warning systems used as decision support tools designed to help growers determine when to apply control measures to suppress crop diseases.
The authors stress that weather data are nearly ubiquitous inputs to warning systems. Grower-operated weather monitoring is contrasted with obtaining data from networks of weather stations, and the advantages and disadvantages of measuring vs. estimating weather data are discussed. Special emphasis is given to leaf wetness duration (LWD), not only because LWD data are inputs to many disease-warning systems but also because accurate data are uniquely challenging to obtain.
