What is vascular wilt disease?

Vascular wilt diseases are caused by pathogenic fungi or bacteria that enter the water-conducting xylem vessels of a plant, then proliferate within the vessels, causing water blockage. The typical symptoms include wilting and death of the leaves, followed often by death or serious impairment of the whole plant.
