Brown Rot across the plant library
8 of the 505 plant guides in this library name brown rot among their diseases. Every one is listed below, linked to its guide and grouped by the kind of plant it is, so you can see at a glance which corners of a garden it turns up in.
This is the library read down a column instead of across a row. Each plant guide names its own diseases; nobody publishes the other view — which of the plants you actually grow share one, and whether the timing they record agrees.
The 8 plants that list brown rot
Grouped by plant type. Where the library attached a note to the entry — “rare”, “on seedlings”, “in wet clay” — that note is printed next to the plant, verbatim, because two plants can name the same disease and mean opposite things by it.

Where it concentrates
Botanical families with more than one affected plant in the library, counted from the same 8 guides above. 8 of 8 are Rosaceae.

How the library qualifies it
Every distinct note the guides attach to an entry for brown rot, verbatim, with how many plants carry it. The other 6 guides list it bare, with no qualifier at all.
- in wet Julys
- More susceptible than peaches due to lack of fuzz
Shared timing — and where it doesn’t agree
4 of the 5 recorded brown rot timings in this library contain that exact phrase. That is a count of what the guides say, not a recommendation — the entries themselves are below, unedited, and the label on whatever you use governs the rest.
Quoted verbatim from the spray-timing fields of the guides that name brown rot. Another 3 of the 8 record a program aimed at a different problem; those stay on their own guides.
- Dormant
- Dormant copper/oil for shot hole + brown rot.
- Growing
- Petal fall: curculio insecticide. Brown rot: fungicide as fruit colors.
- Growing
- Brown Rot: Nectarines are highly susceptible. Spray fungicide at petal fall, shuck split, and pre-harvest.
- Growing
- Petal Fall (Shuck Split): Insecticide (Curculio/OFM) + Fungicide (Brown Rot). Cover sprays every 10-14 days. Pre-Harvest: Fungicide 2 weeks before picking.
- Growing
- Petal Fall: Insecticide essential. Brown Rot sprays crucial as high-sugar fruit ripens.
Timing only — the label is the law
This page reports when the guides in this library say to watch for brown rot and when a treatment is worth considering. It is not a recommendation to apply any 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.
