MobilityHalf-lifeRoot Uptake
Foliar Applications• Broadcast or spot treatments• Application equipment
– Backpack/handheld sprayer– High pressure vehicle
mounted– Aerial (helicopter)
• Herbicides– Glyphosate– Triclopyr amine– Triclopyr ester– Imazapyr
• Surfactants– Penetration– Spreading
Cut Stump Applications• Cut as level as possible• Sweep off sawdust• Treat as soon as possible• Concentrate on living
tissue• Use enough herbicide
Bark
Dead wood
Living tissue
• Herbicides– Glyphosate– Triclopyr amine– Triclopyr ester– Imazapyr
Basal Bark Applications• Herbicides
– Oil soluble (EC)• Triclopyr ester• imazapyr
• Diluents– Vegetable oil
• Most readily breaks down
– Mineral oil– Diesel fuel not
recommended
Hack and Squirt Applications
• Herbicides– Imazapyr– Glyphosate – Triclopyr amine– Triclopyr ester
• Equipment– Spray bottles
• Used for trees with thick or scaly bark
• Cut all the way around stem• Cut all the way in to cambium• Apply herbicide to exposed cambium• Use dyes• Treat within 15 minutes of cut
Foliar spray Poodle-cut
- Low growing, not climbing into canopy
- Climbing into canopy- Cut at 4-5 feet above ground

Ground TreatmentsInitial Treatment:• Glyphosate (1-3% product)• Metsulfuron methyl (2 oz / 100 gallons)• Triclopyr (1-3% product)• Imazapic (1% product)• Imazamox (?)
Follow-up Treatments:• Use a different herbicide than used in initial treatment• Tank mixes• Imazapyr (?)• Aminopyralid (?)• Fluroxypyr (?)

MethodsFoliarBasal barkCut stem
Cat’s-claw vine (Macfadyena unguis-cati)
Triclopyr ester - cut vine, pull away from tree and treat cut surface and bark
Rosary Pea(Abrus precatorius)
• Foliar spray – “dense”infestations-glyphosate, triclopyr amine
• Cut – treat base with triclopyr ester
• Collect seed pods
