bean seed almost or quite free from anthracnose. But it must be possible 

 to obtain such seed every year if the disease is to be avoided in years 

 favorable for its appearance. The practice of selecting from clean pods 

 is the only reliable way to secure seed free from anthracnose (figs. 18 

 and 19). The method in its practical application involves the use of a 

 seed plot, on which the selected clean seed is planted. This plot should

 The pods are so badly affected with anthracnose that they are worthless 



produce the necessary seed for planting the main field the following year. 

 The steps in carrying out the measure are as follows: 



1. Selection, in the fall, of pods having no anthracnose or blight spots. 

 These should be shelled by hand or with a flail, and the seed afterward 

 sorted over to remove all discolored, impure, undersized, shriveled, or 

 broken beans. The amount of seed to be selected in this way will depend 

 on the amount needed for planting the main field. If 40 bushels of seed 

 are required for planting the main field and 20 bushels an acre can be
