The only way to remove kudzu is to destroy its
extensive root system
Cutting from early spring through late fall (as
regrowth appears) will exhaust the stored
carbohydrate reserve in the plant
Late season cutting must be followed up with
application of glyphosate to cut stems,
For small populations or sensitive areas, grubbing is
appropriate, taking care to remove all vines from
around trees and all roots and runners; all plant parts
must be bagged and disposed of in a landfill
For cut stump application, apply a 25% solution of
glyphosate or triclopyr and water to cross section of
a stem; ground must not be frozen to be effective
For foliar applications of herbicide, apply a 2%
solution of glyphosate or triclopyr mixed with water
and a 2.5% non-ionic surfactant to the leaves, being
sure to wet the leaves but not causing runoff;
ambient air temperatures should be above 65° F
Chlorpyralid (e.g. Transline) herbicide can be used
as a foliar application at a concentration of 0.5% and
is selective to plants in the aster, pea, and buckwheat
families only
Prevention of seed production should be a
management priority as it is a prolific seed producer
with a high germination rate; mowing or cutting in
late summer prior to seed production is advisable
Hand pulling is effective, but all roots must be
removed to prevent the shrub from sprouting again;
pulling is best done when soil is damp and loose and
the worker must wear thick gloves to prevent injury
Young plants can be dug up individually
A Weed Wrench® is recommended for sensitive
sites and for uprooting larger plants
For whole plant applications of herbicide, apply a
2% solution of glyphosate mixed with water and a
surfactant; application in late summer during
fruiting is most effective
Can also apply herbicides to freshly cut stumps or as
a basal bark application; apply 25% solution of
glyphosate or triclopyr plus water ensuring to cover
at least 20% of outer stump.
Mowing Russian Olive with a brush type mower and
carefully removing all cut material from site for
disposal is the most effective method
No known pesticide use has been effective in
controlling this shrub
Cut stump treatments with trichlopyr or glyphosate
solution at 25 to 50% solution
Saplings can be treated with 20% Garlon® 4 in a
basal oil as a basal bark treatment. Older trees can
be girdled and then treated with this treatment.
Seedlings can be hand pulled, bagged and removed
