Aphids across the plant library

109 of the 505 plant guides in this library name aphids among their pests. 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 pests; nobody publishes the other view — which of the plants you actually grow share one, and whether the timing they record agrees.

The 109 plants that list aphids

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 pest and mean opposite things by it.

How the library qualifies it

Every distinct note the guides attach to an entry for aphids, verbatim, with how many plants carry it. The other 87 guides list it bare, with no qualifier at all.

Shared timing — and where it doesn’t agree

These entries do not describe one shared window. The 2 guides that record a timing for aphids have no phrase in common, so there is no consensus to report and none is invented here. They are reproduced below exactly as the library holds them, each next to the plant it belongs to.

Quoted verbatim from the spray-timing fields of the guides that name aphids. Another 48 of the 109 record a program aimed at a different problem; those stay on their own guides.

Dormant oil for scale/aphids.

Timing only — the label is the law

This page reports when the guides in this library say to watch for aphids 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.

What else these plants get

Counted over the same 109 guides: the other problems most often listed on a plant that lists aphids. These are co-occurrences in the library’s own records, not a claim that one causes another.
