Targets complete costs to accomplish the work
Payments can’t exceed 100% of landowner costs
2 treatments are “required”
$250 / acre – initial treatment

Invasive Plants Incentive Program – landowner role
1. Meet with GFC forester/technician to show the invasive species –
verify species, and measure acreage
2. Discuss and plan treatment prescriptions
3. GFC will send follow-up correspondence outlining plan
4. GFC will notify you if you are selected (or not chosen)
5. Procure contractor (or plan for self treatment)
a) Contractor reporting obligations!
b) Let us know if you need help finding a contractor
6. Let GFC know when contractor plans to perform work – we can
help supervise
7. Turn in bills, receipts, etc and notify GFC treatment is complete
8. Plan for follow-up evaluations, and treatment #2 (if needed)

Non-native Olives – Control Recommendations
Foliar:
Arsenal AC* or Vanquish* as a 1-percent solution in water (4 ounces per 3-gallon mix) with
a surfactant (April to October). Or when safety to surrounding vegetation is desired,
Garlon 3A as a 2 percent solution (8 ounces per 3-gallon mix).
Basal Bark:
For stems too tall for foliar sprays, apply (January to February or May to October) a basal
spray using Garlon 4 as a 20-percent solution (5 pints per 3 gallon mix) in a labeled basal
oil product, vegetable oil or mineral oil with a penetrant, or where permitted, fuel oil or
diesel fuel, or undiluted, or Pathfinder II when safety to surrounding vegetation is desired.
Elsewhere apply Stalker* as a 6-percent solution (1.5 pints per 3-gallon mix) in a labeled
basal oil product, vegetable oil or mineral oil with a penetrant, or where permitted, fuel oil
or diesel fuel, to young stems.
Cut Surface or Injection:
Or, cut larger stems and immediately treat the stump tops with one of the following
herbicides in water with a surfactant: Arsenal AC* as a 5-percent solution (20 ounces per
3-gallon mix) or when safety to surrounding vegetation is desired, a glyphosate herbicide
as a 20-percent solution (5 pints per 3-gallon mix).
* Non-target plants may be killed or injured by root uptake.

Chinese Tallowtree – Control Recommendations
Large trees.
•Make stem injections using dilutions and cut spacings specified on the herbicide label (anytime except March and April) with
Arsenal AC* (or Habitat in aquatic situations) or Clearcast*; when safety to surrounding vegetation is desired, inject Garlon 3A
or glyphosate herbicides.
•For felled trees and cut saplings, apply an herbicide to stump tops and sides immediately after cutting using Garlon 4 as a
10-percent solution in a basal oil (1 quart per 3-gallon mix) when stumps are less than a 6-inch diameter and a 20-percent
solution (2 quarts per 3-gallon mix) on larger stumps, or apply Garlon 3A or glyphosate herbicides as a 20-percent solution (2
quarts per 3-gallon mix). Ortho Brush-B-Gone (triclopyr) and Enforcer Brush Killer (triclopyr) are also effective for treating cut
stumps and readily available to homeowners in retail garden stores. Follow the label directions.
•For treatment of extensive infestations in forest situations, apply Velpar L* to the soil surface within 3 feet of the stem (one
squirt of spot gun per 1-inch stem diameter) or in a grid pattern at spacings specified on the herbicide label.
Saplings. Apply Garlon 4 as a 15-percent solution (58 ounces per 3-gallon mix) in labeled basal oil, vegetable oil, kerosene,
or diesel fuel (where permitted), or undiluted Pathfinder II when safety to surrounding vegetation is desired, or Stalker* as a 6-
to 9-percent solution (1.5 to 2 pints per 3-gallon mix) in labeled basal oil, vegetable oil, kerosene, or diesel fuel (where
permitted) to young bark as a basal spray.
Seedlings and saplings. Thoroughly wet all leaves with one of the following herbicides in water with a surfactant (July to
October): Arsenal AC* as a 0.75-percent solution (3 ounces per 3-gallon mix), Arsenal Powerline* as a 1.5-percent solution (6
ounces per 3-gallon mix), Krenite S as a 20-percent solution (5 pints per 3-gallon mix), Clearcast* as a 2-percent solution (8
ounces per 3-gallon mix), or when safety to surrounding vegetation is desired, Garlon 4 as a 2-percent solution (8 ounces per
3-gallon mix).
Clearcast added to this control section

Non-native roses – Control Recommendations
Foliar:
Thoroughly wet all leaves with one of the following herbicides in water with a surfactant: April to June (at or near the
time of flowering)—Escort XP* at 1 ounce per acre in water (0.2 dry ounces per 3-gallon mix); August to October—
Arsenal AC* as a 1-percent solution (4 ounces per 3-gallon mix) or Escort XP* at 1 ounce per acre in water (0.2 dry
ounces per 3-gallon mix); May to October—repeated applications of a glyphosate herbicide as a 4-percent solution
in water (1 pint per 3-gallon mix), a less effective treatment that has no soil activity to damage surrounding plants.
Basal Bark:
For stems too tall for foliar sprays, apply basal sprays using Garlon 4 as a 20-percent solution (5 pints per 3-gallon
mix) in a labeled basal oil product, vegetable oil or mineral oil with a penetrant, or where permitted, fuel oil or diesel
fuel, or apply undiluted Pathfinder II (January to February or May to October).
Cut Surface or Injection:
Or, cut large stems and immediately treat the stump tops with one of the following herbicides in water with a
surfactant: Arsenal AC* as a 10-percent solution (1 quart per 3-gallon mix) or when safety to surrounding vegetation
is desired, a glyphosate herbicide as a 20-percent solution (5 pints per 3-gallon mix).
* Non-target plants may be killed or injured by root uptake.
Glyphosate has been the most effective if non-target damage is acceptable.

Chinese Privet invades upland areas too…
Numerous low-growing small stems in pine
stand = good choice for broadcast understory
treatment
Burning may be good first step
Escort XP® (1 ounce per acre) – high volume

Chinese Privet control options
Foliar Treatments:
Escort XP® (1 oz per acre + 0.25% non-ionic surfactant) High Volume Broadcast. Good choice for pine stands but may damage hardwood overstory (Ash, Elm, Dogwood and Cherry are susceptible to root uptake from Escort). Growing season.
Glyphosate (2-5% solution with water) applied as a directed foliage spray DURING THE DORMANT SEASON. Good choice for hardwood stands with numerous sprouts or stands with desirable plants near privet. 41% activeingredient products.
Accord Concentrate® (up to 7 pints per acre) applied aerially DURING THE DORMANT SEASON (within piedmont region – GFC trial). 54% active ingredient product labeled for areas where standing water occurs. http://www.gatrees.org/ForestManagement/documents/AerialGlyphosateApplicationtoControlPrivet2009.pdf

Chinese Privet control options
Cut Surface Treatments: as a cut surface or injected into the cambium. Safe around desirable trees where privet must be removed.
• Krenite® (mixed 50-50 with water plus surfactant)
• Arsenal AC® (5% solution with water plus surfactant)
• Glyphosate (mixed 50-50 with water) – 41% active ingredient products
• Garlon 3A® (20% solution with water plus surfactant)
Basal Bark Treatments: Safe around desirable trees where privet must be removed.
• Garlon 4® (20% plus crop oil) applied as a basal bark treatment. Good treatment option for large privet with single stems and bushy canopy.
Other Considerations:
• Privet eradication will take at least 2 treatments over 2 growing seasons
• Most privet seed will germinate within one year of maturing
• Re-sprouts should be at least 24” before treating
