Fusarium wilt in Massachusetts?

[Jonathan_E]

Tomatovillans,

I know that fusarium wilt is not common as far north as Massachusetts, but I can't figure out what else is ailing a couple of my plants. What in particular makes me suspect FW as the culprit is the "unilateral" nature of the chlorosis and wilting. In other words, only one side of the plant yellowed and wilted initially; in some case, only one side of a leaf yellowed; in some, the leaves on only one side of a stem yellowed; and one of the fruit ripened only on one side.

Pictures are attached; suggestions are welcome.

Best regards,

Jonathan
