1. Sapium and Eichhornia
From: Doria Gordon (dgordon(at)botany.ufl.edu)
Greg Jubinsky, of the FL Department of Environmental Protection
(jubinsky_g(at)epic6.dep.state.fl.us) may be the best person for you to
contact about Sapium and Eichhornia. A U.Florida publication on the
invasive plants control says the following for Sapium:
Cut stump treatment of 20% Garlon 4; or basal bark application of 15%
Garlon 4 to trees <10 in dbh or 20% Garlon 4 to trees > 10 in dbh
(non-aquatic sites only). Experimental cut stump and frill applications of
2-3% Arsenal [only if no desirable species present] have proven effective
in aquatic sites and an application has been made to add to the label.
seedlings up to 10 in tall can be hand pulled.
This publication does not list hyacinth.
Sapium has been shown to out-compete water tupelo and other bottomland
hardwood species in high shade and in flooded conditions (work by Sharitz
et al).

We have some preliminary information on the control of water hyacinth in
small areas. Call Holden Brink-Wetlands Manager at the Cosumnes River
Preserve at 916.683.1740. He will be happy to provide information on the
hand removal of water hyacinth.

3. Water hyacinth and chinese tallow
From: Carlen Emanuel (cemanuel(at)zebra.net)
Keith, for water hyacinth I would contact the South Florida Water
Management District for the latest in control methods and success.
Texas TNC might help on Chinese tallow since it has taken over there.
Burn it repeatedly if possible and pray for drought. Wish I could help
you more.
