Crop productivity on hilly terrain may vary greatly from upper to lower slopes due to differences in fertility, moisture and micro-environment. Plant diseases are affected by these conditions, resulting in differences in yield and quality among slopes. Precision farming technology allows the characterization of a field into specific landscape positions such as slope position and may increase the production efficiency by applying the optimum amount of inputs to each position. In order to apply precision farming technology to plant pathology it is necessary to understand the relationship among micro-environments within a field created by slope and the occurrence and severity of plant diseases. The objectives of this study were to determine: 1) the variation in diseases of canola and wheat over the landscape, 2) the interaction of slope position with fungicide application for Alternaria black spot control in canola, and 3) the interaction of soil nutrients and seeding rate with diseases of wheat.
