It doesn't go after insects or mites, so the only wait is for the spray to dry. Release on the same day if you like.

Spores need
a clean landing.

Bacteria hold the ground

How it works

Bacteria hold the ground

The bacteria spread across the leaf and stop disease spores sprouting. Clean leaves stay clean; that's why early matters.

The maker

Arber

Plant care made
from biology.

Arber builds its range from living things: bacteria that guard leaves, a plant extract that wakes up a plant's own defenses, and nutrients from produce that would otherwise have been thrown away. Its sprays use the same kinds of actives commercial growers rely on, registered with the EPA.

We carry it because its sprays can share a plant with our bugs when the timing is right, and every Arber page here gives you that timing.

Before you order

Your questions, answered

Something else? Ask Toby in the chat, bottom right.

Can I use it with beneficial insects?

Yes. They can go out once the spray has dried; it works on fungus, not insects or mites.

Can I use it indoors?

No, it needs a garden hose. Bio Fungicide concentrate in a spray bottle is the indoor version.

Will it clear black spot that's already there?

No. Pick off and bin marked leaves, then spray to protect the clean ones and the new growth.

How do I know I've covered it?

The undersides glisten too. Most pests and spores sit under the leaf, so tip the spray up from below before you move on.
