ANTHRACNOSE OF SCARLET RUNNER 289 



When pods are badly diseased, they are often con- 

 torted ; the beans are also some- 

 times attacked. 



Professor Halsted states that 

 this fungus is parasitic on the 

 living rind of cucumbers, pump- 

 kins, water-melons, and musk- 

 melons. 



PREVENTIVE MEANS. Spray 

 with Bordeaux mixture when 

 the disease first appears on the 

 stem or leaves, which will pre- 

 vent its passing on to the pods. 

 Badly diseased plants should be 

 removed. Seed obtained from 

 plants where the disease has 

 existed should not be used. 

 Plants grown in damp situa- 

 tions are most liable to the 

 disease.
