Fusarium Wilt
One side of the plant wilts while the other looks fine, lower leaves yellow first, and recovery never comes even after watering — the fungus has plugged the water-carrying vessels. Slice a stem low and the interior ring is stained brown.
Disease checklist
Four things to look for. If most of them match what you are holding, you are in the right place.
What gets rid of it
Gentlest option first. For most backyard cases the first one is enough, so try these in order and stop as soon as it works. If you do spray something, the product label tells you how — please read the notice further down.
1Pull and trash infected plants
There is no cure in season; removing the plant (never into compost) limits the soil load.

The F in tomato codes like VFN. In known fusarium soil this is the only reliable path.

The fungus persists in soil for years; move the crop family and give beds 4+ years where you can.

Which plants get fusarium wilt
Every plant we cover that gets fusarium wilt, grouped by type — tap any one to open its page. A note beside a plant came from that plant’s own entry, because the same disease can be a minor nuisance on one plant and a serious problem on another. Plenty of plants we do not cover get it too.

Plant families hit hardest
Related plants often share the same problems, so if one plant in a family has it, check the others. The largest group here is Cucurbitaceae, with 2 of the 7 affected plants.

When to treat
There is no treatment. Pull affected plants, rotate away from that ground, and grow resistant varieties.
Timing only — the label is the law
This page tells you when to watch for fusarium wilt and when treating is worth considering. It is not a recommendation to apply any particular product. Read and follow the product label before you spray — under federal law the label is the legal instruction, and using a pesticide against it is illegal.
- Check the pre-harvest interval. Every product that’s cleared for an edible crop sets a minimum number of days between spraying and picking. Find it on the label before you spray anything you intend to eat.
- Check the re-entry interval before you or anyone else works in the treated area again, and use the protective equipment the label names.
- Confirm the product is registered for your crop in your state. This page groups many different crops together, and a product legal on one of them is not legal on all of them — state registrations differ too. Your state pesticide agency or local extension office can confirm both.
- Rates and mixing instructions come from the label, never from us. We don’t publish them because they differ by product and formulation.
Other problems on the same plants
If a plant gets fusarium wilt, these are the problems it most often gets as well, so they are worth checking for while you are out there. They tend to appear together; one does not cause another.
