The preferred hosts of E. tracheiphila are in the cucurbit family (wild and cultivated species), of which cucumbers are “the most susceptible host, followed by. Erwinia tracheiphila is the causal agent of bacterial wilt of cucurbits, an economically important phytopathogen affecting few cultivated. E. tracheiphila induces severe wilting symptoms in many wild and cultivated cucurbits, especially cucumber (Cucumis sativa) and musk melon (Cucumis melo ).

Topical Meetings and Workshops. Careers In Plant Pathology. Resistant cultivars of cucumber are being developed. Use crop rotation to reduce beetle numbers in adjacent areas. Based on work by Michasia Harris and Bugwoodwiki user Jbrock. However, the disease will soon spread down the runner and then infect the whole plant, causing it to shrivel and die.

Bacteria spread throughout the plant through adjacent xylem vessels.

Weather has little effect on the incidence of wilt, but may influence the rate of symptom expression. Initially, wilting may be confined to a portion of a leaf trachiephila eventually spreads throughout the entire leaf, to other leaves on a branch and subsequently throughout the plant Walker, Users may want to set up a specific directory and file naming scheme for storing images; otherwise, they will be saved using your system defaults.

Foliage appears yellow before the entire plant collapses and dies. A diagnostic procedure for determining bacterial wilt Latin, is to cut the stem, bring the two cut pieces back together and slowly pull apart.
