Professional Forestry Herbiciding Since 1995
What Is Understory Herbiciding?
Understory herbiciding is a controlled vegetation treatment used to manage undesirable plant growth within 15 feet of the forest floor. It creates the ideal conditions for hardwood and pine regeneration following timber harvests.
Contact Herbicides
• Absorbed through foliage
• Require rain-free period
• Trans-locate into root systems
Residual Herbicides
• Activated by rainfall
• Absorbed through root systems
• Often applied during dormant foliage periods
If a timber harvest area contains more than 40–50% competitive ground cover, herbiciding is often the most effective method for promoting regeneration.
Competitive vegetation may include:
• Fern
• Beech brush
• Striped maple
• Multiflora rose
• Mile-a-minute
• Japanese Silt Grass
When Is Herbicide Application Recommended?
• 60 ft spray coverage
• GPS-guided mapping and acreage calculation
• 450-gallon tank capacity
• Up to 100 acres per day
• Raven 440 precision calibration
Our tracked equipment is designed to operate efficiently on steep and rough terrain.

Proven Regeneration Results
We typically achieve 90–100% vegetation control. Even 80% control creates a strong regeneration window lasting 4–5 years.
This area was logged, allowed to regrow for one year, then treated with herbicide. It was planted with pine trees the following spring.

FAQs
When is a herbicide application warranted?
1
Herbicide applications are typically recommended after a timber harvest designed to promote regeneration. If more than 40–50% of the area contains competitive ground cover, herbiciding is often the most effective way to eliminate vegetation that competes with new growth.
Spray season generally runs from early June through mid-September, depending on location and vegetation type. Certain selective residual treatments may begin as early as March or April.
2
When is the best time to spray?
Herbaceous (soft tissue) vegetation typically shows full results within 4–6 weeks. Woody vegetation generally requires one full growing season to see complete effectiveness.
3
How soon will we see results?
How long will the treatment remain effective?
4
With an 80% or greater vegetation control rate, herbicide treatments typically remain effective for 4–5 years, providing a strong regeneration window.
