BEAN 



Anthracnose (Collet olvidnun lindemuthianum Bri. & Cay.), 

 Fig. 383. This is a fungous disease also known as rust or pod spot. 

 Rusty brown or reddish sunken spots occur on the pods with simi- 

 lar spots on leaves and stems. Seed from disease-free regions or 

 from selected disease-free pods will, it is believed, produce dis- 

 ease-free crops. Seed treatment or hand picking of seed is 

 useless. Spraying has not been profitable.

Blight (Pseudomonas phaseoWErw. Smith), Fig. 384. Irregu- 

 lar water-soaked patches appear on leaves, stems and pods, which 

 later become dried out and brownish in color. Diseased seed is 

 the main source of the bacterium which causes the disease. State- 

 ments above in regard to the control of anthracnose are largely 

 applicable.
