On southern red oak (Quercus falcata) sites that were clearcut, eastern
redbud increased on plots where flowering dogwood, red maple (Acer
rubrum), and hickory (Carya spp.) were injected with herbicides. This
increase may be in part due to bird dispersed seed since bird activity
was high in this area .
The response of eastern redbud to tebuthiruon or triclopyr treatments
was reported by Stritzke and others . Neither of the herbicides
used resulted in more than 66 percent kill of eastern redbud, and by 2
years after the treatment, canopy cover of all species had increased to
94 percent (plots with no herbicides averaged 175% canopy cover) .
Picloram has been reported as effectively suppressing sprouting in
Eastern redbud is relatively free of serious insect pests and diseases
. It is fed upon by gypsy moth larvae (later stages) only when
preferred species are not available .
Eastern redbud is rated as moderately sensitive to ozone damage .
