This^blight now has its greatest development along the Pacific coast, especially in C)range and Los Angeles counties. California. The germ which causes this'dis- ease is a newly described species of Pseudomonas [P. JHiihoidis). Oitt'ereut effects of the disease are shown in Fig. 27U. The organism of Walnut bacteriosis winters in the fallen nuts, in the diseased tissues of affected branches, and especially in the pith cavity of the latter.
