Fusarium wilt shows up again.. remove plant?

[windclimber]

The dreaded Fusarium has showed up on one of the Giant varietys I am growing... Slankard....

Classic signs,.... distinct bright yellowing on one side only of the leaf, and plant on the lowest branches.

Complete yellowing of one branch and complete wilting.

Should I pull it very carefully as to not spread in the garden and other plants close by?

Will it's removal increase chances for the others close by?
I have noticed topshoots on nearby plant wilting in the heat of the day and then recovering......gettin kinda nervous.
