Pest & Disease Guides

Knowing it is a pest is only half the job; the other half is treating it without harming the plant.

These guides help you identify what you are dealing with, understand why it showed up, and work through a least-toxic-first treatment ladder.

They come from my plant pathology background and the pest guides already on the site.

All guides are instant digital downloads.

Because you receive the file straight away, all sales are final and non-refundable once a guide has been downloaded.

This policy applies to plantbio.org guides and printables only.

Purchases made through affiliate links are handled by the individual seller and follow their own refund policy.
