A computerized warning system for fire blight control.
A warning system for the control of fire blight (Erwinia amylovora) on pears and apples based on determination at the local level of a climatic potential (CP) and an inoculum potential (IP) is described. These potentials are combined in order to estimate an overall level of risk. A recommended control measure is associated with the risk assessment. Among the inputs required, climatic data, forecast of climatic parameters and precise information about the disease situation in the plot and its surroundings are essential. The warning system is computerized, and has been devised for use with an IBM-PC personal microcomputer; its availability to growers and plant protection services is presently under study.
