2020/2021 Proposed Treatments
Melaleuca Brazilian pepper All species
Lygodium Australian pineHighlights: Broward County
Herbicide Mixes:
• 1% Trycera, .5% GroPerfect: Great on Lygodium, Grape Vine, Syngonium, Dalechampia, and most
broadleafs and vines (GroPerfect is type of fertilizer).
• 2% Finale, .5% MSO: Great foliar treatment for Guinea and invasive cane grasses. Used at lower rates
than Glyphosate and needs less retreatment.
• 40% Glyphosate, 10% Imazapyr: Cut stump mix. Great on all invasive trees and vines, Syngonium and
Smilax. Also very effective on Cissus; cut vine and dip the cut portion of upper part of the vine into mix.
• 5fl Glyphosate, 5fl MSO per gallon: Foliar mix for Pothos and Syngonium. Multiple treatments needed
so be careful to stay within label rates. Works best after initial treatment, let dry, and reapply second
treatment same day.

Corridors of Invasion
Noteworthy results
• 16 new County records
• ECISMA EDRR Species identified
• Cyperus alopecuroides (Foxtail flatsedge)
• Eucalyptus torelliana (Torell’s eucalyptus)
• Furcraea foetida (Mauritius hemp)
• Pteris tripartita (Giant brake fern)
• Hemarthria altissima (limpograss),
Heteropogon contortus (tanglehead grass)
and Imperata cylindrica (cogongrass) are
common and, in some locations, abundant
along right-of-ways in the ECISMA footprint.
