The California Wild Walnut - Juelans Calitorni Walnut Bacteriosis. âChief among the more serious diseases of Juglans regia in the United States is a bac- terial blight of the nut, branch and leaf of that tree. This blight now has its greatest development along the Pacific coast, especially in Orange and Los Angeles counties, California. The germ which causes this dis- ease is a newly described species of Pseudomonas [P. juglaiidis). Different effects of Ihe disease are shown in Fig. 2714. 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. New in- fections occur as soon as spring growth begins, taking place near the growing point of branches, in the open- ing leaves, and upon the young and tender nuts. The finer lateral veins of the leaves and the adjoining par- enchyma are destroyed, and the midrib is often af- fected.
