Control. 



The treatment as outlined for scald gives satisfactory control 

 for the rot disease (page 195).

ANTHRACNOSE 



Caused by Glomerella cingulata (Stoneman) Sp. and von S. var. Vaccinii 



Shear 



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 uni- 

 form in appearance. Berries affected with anthracnose may 

 be very soft or not. The diseased flesh is usually light-col- 

 ored. 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.
