Noxious weeds; amends definition, commercial viability, phase-out period, report.

The document structure was converted from a continuous text block to a numbered line-by-line format, and the header information was reorganized to include a bill number and session date.

Removed the 'Enrolled' status and chapter number header, indicating this is no longer the final signed version but a committee substitute.

Added standard substitute bill formatting, including page numbers, draft status, and committee attribution.

Adjusted line breaks and paragraph spacing to fit the substitute bill layout, while preserving the exact wording of the legislative content.

Added a mandatory phase-out period for noxious weeds commercially propagated in Virginia: 2 years for grasses, forbs, and vines; 4 years for shrubs; and 7 years for trees.

Added a requirement for the Commissioner of Agriculture to conduct a comprehensive review of noxious weed regulations and report findings to legislative committee chairs by November 1, 2026.

Modified the definition of 'noxious weed' to explicitly state that the definition does not apply when in-state production is commercially viable or the plant is commercially propagated in Virginia, triggering the new phase-out rules.
