HERBICIDES AND
WEED CONTROL
Read labels carefully for their general use on
warm season grasses
Most herbicides that can be effectively used on
bermudagrass are phytotoxic on paspalum
CHECK THE GENERAL TURF USE LABELS OR WARM SEASON

GRASS ENCROACHMENT
Paspalum into bermudagrass
•Dual combination of Confront (triclopyr +
clopyralid) + MSMA (0.5 and 2.0 lb.ai./A)
•Applications at 3-4 week intervals during
the Spring after full greenup
•At least 3 repeat applications may be
needed
Bermudagrass into paspalum
•Single herbicides or combinations have been
ineffective; too much damage on the paspalum
•Have researched Prograss, Fusilade, and
Envoy
PLANT GROWTH REGULATORS
•Primo (trinexapac-ethyl): 0.13 ai/A on
fairways; 0.125 fl oz/M or less on greens
•Trimmit (paclobutrazol): not sensitive to
rates or timing of applications;
seed head suppression; minimum growth suppression
•Proxy (ethephon): seed head suppression;
some growth suppression
•Cutless (fluprimidol): growth suppression
<75 F and >85 F
