This picture comes from Michigan. Jeffery Eager submitted this picture of a 30 inch test row of soybeans with white mold. This fungus can be devestating to soybeans. The fungus can stay in a field for many years even when crop rotation is heavily practiced. Here is an explaination of white mold from Michigan State University:

White mold, also known as Sclerotinia stem rot, is caused by the plant pathogenic fungus Sclerotinia sclerotiorum. The host range for this pathogen is very wide and includes green beans and dry beans, tomatoes, potatoes, green peppers, canola, and many others. Once white mold becomes established in a field it is very difficult to manage. Because of its wide host range, and its ability to survive in the soil for many years, rotation contributes little to control. If possible, only one white mold susceptible crop should be grown in the rotation. Rotation with a non-susceptible crop such as wheat or corn will help reduce the build-up of the pathogen in the soil but will not eliminate it from a field.

Remember, we are always looking for more agricultural pictures from anywhere in the world.
