A computarized warning system for fire blight control

Abstract

A warning system for the control of fire blight in pear and apple has been described. It is based upon the determination at the local level of a climatic potential (CP), and an inoculum potential (IP). These potentials are combined in order to estimate an overall level of risk. A recommended control measure is associated with this risk. Among the inputs required, climatic data, forecast of certain 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. © 1991.
