Analyzing Cost Effectiveness of EPIPRE 1

EPIPRE is an integrated pest and disease management system for wheat, fully computerized, based on on‐line calculations of costs and benefits of pesticide treatments; it is field‐specific and utilizes disease and pest monitoring in the field. The development of the project took five years (1977/1981). Cost effectiveness has been estimated in retrospect and in prospect using 1980 as a base year, covering the period 1977 through 1985. Future costs were disccrunted at a 10 % rate. The Net Present Worth of the project was estimated at nearly eight million Dutch guilders. The nonmeasurable effects of the project seem to be even more important than the measurable effect.
