Uh oh, looks like I have a systemic wilt

slowrolling · June 5, 2012

So for the past couple of weeks I've noticed yellowing at the base of some of my plants. I've pretty aggressively trimmed off any effected branches and sprayed some organic copper fungicide several times now. However it doesn't seem to be preventing from popping back up.

I assume I am either dealing with fusarium or virticillium wilt. What does the rest of tomatoville think?

The first two pictures are all from the same plant. The third pic is from plant2 and the fourth pic is from plant3. This is probably my third time pruning off effected limbs.

If it is one of these wilts should I keep aggressively pruning or just let the wilt do its thing and keep the branches on the plant?

Luckily all of my tomato plants seem to be going pretty well, so I'm hoping they can keep ahead of the wilt if I can't do anything about it. Suggestions?

Is the plant itself wilting, or are you just getting this (in my opinion) relatively minor yellowing of certain leaves?

How tall are the plants? Is it only the bottom leaves? What percent of foliage have you removed from each plant?

small percentage less than 10% plants are 3-4.5 ft tall.

I have hacked significantly more branches with more yellowing in previous days last week which is why its just a small amount today.

If you are only removing a small percentage of bottom leaves and the plant isn't wilting, then my thinking is along the lines of Feldon's - it looks like what I would expect from normal senescence.
Maybe someone more familiar with the blights will see other possibilities.

With fusarium, you see the leaves of entire branches turning yellow but the affected branches are scattered randomly throughout the plant.

Have you been fertilizing your plants? Ami

I've had two Better Bush varieties do this this year. Random leaves popping up yellow and then wilting. I hacked them up heavily and treated daily with organic fungicide. One has really rebounded and the other is in the process of doing so.

I'm new, but I wanted to ask...what "organic fungicide" did you use?
