infection was noted on the exotic species, Adsuki, Kulthi, Rice and Moth 

 beans, but occurred to a slight extent on Urd bean (Phaseolus mtingo) , 

 Mung bean (P. ati7-eiis) , Hyacinth bean {DoIicJws lablab) , and White 

 Dutch Case-knife bean (P. multiflorus) . 



Mosaic, which, like the preceding disease, is carried in the seed, 

 occurred rather generally. It was noted as early as May 25 at In- 

 dianapolis, and later during the season at Vincennes and Lafayette. In 

 the variety plot above mentioned, mosaic occurred to a greater or less 

 extent on all varieties except Wardwell's Kidney Wax, Red Kidney, Sad- 

 dleback Wax, Dwarf Horticultural, Robust Pea, Black Valentine, Im- 

 proved Goddard and Webber Wax. Mosaic also occurred on the Adsuki 

 bean {Phaseolus angulans) , Urd bean, and Mung bean but not on the 

 Kulthi bean {Dolichos bifloo-us) , Rice bean (Phaseolus calcaratus) , Moth

bean (P. aconitifolius) and Hyacinth bean. Efforts to cross inoculate 

 beans with soybean mosaic were unsuccessful. Unmistakable evidence 

 of mosaic transmission in the seed of the Adsuki bean was obtained by 

 both field and greenhouse tests. 



During the July drouth, R. C. Friesner found a root rot and wilt 

 resembling the Fusarium root rot disease in a garden plot of Kentucky 

 Wonder beans at Indianapolis. In late-planted beans near Lafayette 

 there was considerable fungus injury to the crop of seed owing to the 

 extremely wet weather in the fall. Staining and shrivelling of the 

 seed were the outstanding effects produced. 



Lima bean. — A bacterial spotting of the leaves and pods due to 

 Pseudomonas plmseoli was commonly noted on both bush and pole 

 varieties in gardens and to a considerable degree on the canning crop 

 in Johnson County at the time of harvest in September (fig. 3A). The 

 causal organism was isolated from pod and leaf lesions.
