Should local governments use chemical herbicides to remove invasive plants in your area?
In 2026, Knoxville initiated a new three-year program using chemical herbicides to eradicate invasive kudzu across several city locations. This strategy replaces previous attempts to control the plant using goat grazing, which failed to prevent regrowth in subsequent seasons.
Why it matters
Kudzu is an invasive species that poses a significant threat to native East Tennessee plant life. City officials moved to the herbicide program because previous biological control methods proved ineffective at stopping the plant from re-establishing itself.
The city has implemented a 3-year plan to manage kudzu through direct leaf application of herbicides. This protocol includes a multi-phase approach involving active eradication, follow-up spot treatments, and long-term monitoring for native regrowth.
The players
City of Knoxville
The local municipal government responsible for managing public parks, greenways, and invasive species control initiatives within city limits.
The details
City crews are currently applying herbicides to kudzu at the Chapman Highway site, where officials report that most of the plant life is already dead. Similar treatments are underway at Fort Dickerson Park and the Third Creek Greenway, while crews are also clearing invasive honeysuckle at the Holston Chilhowee Pool.
Timeline
2026: The city is in the first year of the new herbicide program.
2027: The city will perform follow-up spot herbicide treatments.
2028: The city will transition to monitoring for native plant regrowth.
The Big Picture
The city's herbicide program follows the Tennessee invasive species management guidelines for restoring native plant biodiversity. This approach marks a departure from traditional biological control methods as the city pivots toward aggressive chemical suppression to protect native ecosystems.
Residents can expect improved access to public spaces like the Third Creek Greenway as invasive kudzu and honeysuckle are removed. The initiative aims to restore native plant health, which will eventually enhance the ecological diversity of local parks and trails.
The takeaway
Effective invasive species management often requires moving beyond singular solutions to comprehensive, multi-year treatment strategies. Homeowners can support city efforts by identifying and removing invasive plants like kudzu from their own properties to prevent further spread.
