Hey
guys! I have listed the 5 most notorious, noxious weeds known to man.
Well, ok maybe not, but these well-known weeds are quite difficult to
control.
(top left) The first ones on our list are the
Sedges. These include but are not limited to yellow nutsedge, purple
nutsedge and kyllinga species. These guys
look like grass and if your lawn was pure nutsedge it would be no big
deal. Because our lawns aren’t they need to go! These plants reproduce
through seed and underground “nut shaped” rhizomes. The best way to
control these plants is to spray over-the-top with products such as
Image, Dismiss, or Sedgehammer to name a few.
(top middle) The
second weed is a woody herb called Chamber Bitters. I’d rather drop a
bowling ball on my tongue than deal with this menace! This plant looks
like a dwarf mimosa tree and carries seed on the backs of its leaves.
These things show up in mid June and proliferate like rabbits. The best
control is a pre-emergent containing Gallery, followed by over -the
-top applications of products containing 2, 4, D.

Crabgrass is the scourge of suburbia. This stuff is considered a grain.
Again, if your lawn was pure crabgrass and you cut it oh, um, every day
it would look great. However, we don’t and we won’t so this pest must
bite the dust also. Pre-emergent control with products such as
Barricade or Dimension work well. Clean up stragglers by going over-
the- top with products such as Drive, Vantage, or Tenacity to name a
few.
(bottom left) Lespedeza! , "Gesundheit"! Lespedeza is a
sprawling, ground- hugging weed that drives homeowners crazy because it
grows so quickly. It appears in the early spring, persists all season
and reproduces by seeding. For pre-emergent control use Dimension in
the early spring, then go over-the-top with Trimec, Speedzone Southern
or Manor.
(bottom right) The last grass on the list that causes
an unsightly mess has two pronunciations depending on whether you’re a
Yankee or a Southerner. Annual Blue Grass is usually called by its
genus and species (Poa annua). Thus, those from the north follow the
strict Latin nomenclature, while those from the south run it together
and give it the more friendly pronunciation of “Poanna”. However, there
is nothing friendly or cute about this grass. It grows in clumps,
reproduces from seed and starts showing up in the late fall. The best
control is to apply a pre-emergent such as Barricade or Dimension in the
early fall followed by two more applications three months apart. Clean
up remaining stands with herbicides by spraying products such as
Certainty or Atrazine."
