VERTAA
Verticillium albo-atrum is a soilborne fungal pathogen that causes Verticillium wilt in a wide range of host plants, including vegetables, ornamentals, and woody crops. The fungus invades the plant through the roots, colonizes the vascular system, and disrupts water transport. It survives in soil for many years as microsclerotia, making management difficult. The pathogen is primarily spread through infested soil, plant debris, and infected planting material, but seed transmission has been reported (and unverified) in older reports for some crops.
