determined. No importance is attributed to the comparative yield in 

 number of pods given in table 7, as the seed was mixed and more plants 

 of a prolific nature may have been present in one row than in another. 



It is seen from table 7 that there was a decided control of the disease 

 by spraying with either bordeaux or lime-sulfur. The control is especially 

 noticeable on pods three days after picking. 



The results with field beans grown from healthy seed are given in table 

 8. It is seen from this table that spraying the vines with either bordeaux 

 or lime-sulfur materially reduced the percentage of spotted pods due to 

 anthracnose. The spraying does not appear to have controlled the blight. 



The pods sprayed with bordeaux in the above experiments were decidedly 

 discolored by the precipitate from the mixture. Fawcett (1907) points 

 out that this may be avoided by making the last application with ammonia- 

 cal copper carbonate, which leaves no stain. The pods sprayed with 

 lime-sulfur showed no evidence of stain at picking time. 



In 1912 complete results from spraying were obtained from only a 

 small plot, two-thirds of which consisted of Red Marrows planted with 

 seed from clean pods while the other third of each row was planted with 

 spotted seed of mixed varieties. The planting was done on June 13, 

 and applications of fungicides were made on July 7, 17, and 26, and August 

 6. Bordeaux (4-4-50) and lime-sulfur (32° Baume, 1-50) were the 

 fungicides used. The results are given in table 9. From this table it is 

 seen that no control of anthracnose was obtained from spraying, and 

 that seeds from clean pods were nearly as badly affected as those from 

 spotted seed. Earlier in the season (July 26), however, the plants from 

 clean seed had shown practically no infection, but infection was common 

 on the plants from spotted seed. Cool, rainy weather during August 

 brought about abundant infection from numerous sources. 



In 1913 spraying was done on seven varieties planted in eleven plots 

 50 feet long. Plots 1, 2, and 3 were planted with seed a small percentage 

 of which was spotted with anthracnose; plots 4, 5, 6, 7, 8, and 9 with 

 seed a large percentage of which was similarly spotted; and plots 10 and 

 11 with seed from selected clean pods. The planting was done on June 29. 

 The Red Valentine and Challenge Black Wax beans did not germinate 

 well and were replanted on July 12. Applications of fungicides were made 

 on July 16 and 26, and August 6 and 16. The Navy Pea and Red Kidney
