How long does verticillium wilt last?

Verticillium wilt may kill a small tree in one season, but larger trees may take several years to die or may recover completely.

Can you spray for verticillium wilt?

What is the difference between Fusarium wilt and verticillium wilt?

Fusarium wilt enters the tree through the roots, while verticillium wilt can enter the tree through the leaves or stems. Fusarium wilt is host-specific, while Verticillium wilt is hosted by almost 200 different plant types.
