Although cranberry anthracnose was not reported prior to 1907, it has a wide geographical range through the eastern United States. It is a much less injurious disease than either scald or rot (see pages 192 and 201, respectively).

It is not easy to diagnose a case of the anthracnose disease by gross examination of affected berries. They are not uniform in appearance. Berries affected with anthracnose may be very soft or not. The diseased flesh is usually light-colored. Sometimes flesh - colored, sticky masses of spores appear on the lesion; however, this is not a constant character.

Little of importance is known regarding the life - history of the causal fungus.

The disease is often associated with scald and rot and may be controlled by the use of bordeaux mixture as employed for those diseases.
