Abstract
The raison d’être for the study of plant pathology is to reduce crop loss due to disease (Carlson and Main 1979). To achieve these lower crop losses, plant diseases are controlled with chemicals applied before or during the epidemic, with plant resistance to disease, and with sanitation and other crop management practices. To determine the superior treatment among the many choices that may be available for the control of disease, or to predict the disease progress after the application of a control measure, is frequently not an easy task. It is the purpose of this chapter to provide suggestions, methods, and experimental techniques to aid in the interpretation of the disease progress associated with control procedures. Hopefully, the improved interpretation of disease progress will enable the researcher to make the choice of the best control measure, to predict future disease with or without the application of the control measure, and to correlate disease progress to spore numbers, weather, and plant growth which should lead to better advice to growers on the control of diseases.
