A Technical Report from The Bartlett Tree Research Laboratories 400
Verticillium wilt is a soil borne fungal disease that can be fatal to a wide range of woody plants. It is also a significant disease of vegetables and row crops. This vascular disease causes the water-conducting vessels of the plant material to become blocked. This produces symptoms of severe moisture stress in the leaves such as curling, drying, and abnormal coloration. Dieback and death may follow over the next one to three years. Through research or observation, some plants have been determined to be highly resistant or immune to Verticillium wilt disease. Listed in this report are species that can safely be used on sites with a history of the disease.
