What is Late Blight Risk Monitoring?
Late Blight Risk Monitoring is a service provided by Michigan State University to Michigan potato growers. The objective of the program is to provide growers with up-to-date information to help them make timely and effective disease management decisions. Late blight of potato, caused by Phytophthora infestans, spreads in potato canopies by continuous leaf and stem infection when inoculum is present and favorable environmental conditions, typically moist cool weather, exist. The Late Blight Risk Monitoring website uses real-time weather data from the Michigan Agricultural Weather Network (MAWN) to estimate when conditions are most favorable for a disease epidemic and provides fungicide recommendations appropriate to that risk. For more information see: Web-interactive integration of regional weather networks for risk management of late blight in potato canopies.
