Detecting a disease in its early stages of development is important to managing disease risk. Last spring, I wrote an article on making a scouting plan for soybean diseases. I received some comments and decided to redo the article by adding new disease problems and specifying regions where certain diseases have been prevalent in the past few years. There are several reasons for making a scouting plan. First, early detection of a disease can help you to make management decisions to prevent disease problems before they take place. Second, the occurrence of different diseases varies in a growing season and certain diseases may be important only in fields that have the right disease conditions.
