In past years I had a bigger problem with bright yellow leaves initially up only one side of the plant (or sometimes affecting just one stem) and the tell-tale brown stem interior of Fusarium before the whole plant went belly up.
Here's a nice page for Verticillium Wilt,symptoms, etc.,I saw it only twice, and was taught that the wilting was indeed onesided on the plant and both times that was true.

I
was also taught that sometimes the plant would outgrow the infection.I never saw that with my two plants.

Who taught me? The local Cornell Coop-Ext person who was taught by Zitter at Cornell,who was an expert in tomato diseases, known worldwide,and the one who led me to coin the word CRUD.
