Good morning,
Does the extension have a service available to diagnose plant diseases? If so, how much does that run? I have some sort of tomato wilt that's been occurring for the last couple of years, and getting worse. I can't figure out if it's Verticillium, Fusarium, or Bacterial Wilt. This year I'm going to lose about 60% of my tomato plants, despite treating three times throughout the season this year with antifungals and bordeaux mixture. The bordeaux mixture provided marginal success last year, but the plants are unresponsive this year. I can also provide photos as needed.
