1. (a) Blackheart, which is decayed or wet, and which affects one or more branches composing the heart of the stalk.
2. (b) Insects, if more than four branches are each damaged by more than an aggregate area of one square inch. Mere presence of insects is not serious damage.
3. (c) Seed stem, the length of which is more than four times the diameter of the stalk measured at a point two inches above the point of the attachment of the outer branches to the root.
4. (d) Pithiness, a distinct open texture with air spaces in the central portion of more than four branches, will be considered serious damage if this condition affects more than two-thirds of the distance between the base of the petiole and the point where the leaf branches are attached. This two-thirds distance need not be contiguous. Distinct open texture means openings which total more than one-fourth the distance across the surface of a transverse cut in the celery branch.

Serious damage means injury which is due to any of the following:
