How Weeds Spread
How to Kill them
Other Interesting Facts
Annual bluegrass
Likes moist areas
Leaf blades that are crinkled part way down
are one way to identify the Annual Bluegrass.
Spreads by seeds
Starts to Germinate in Late
The problem is that it creates
poor footing for athletes on turf
fields, and spreads rapidly because
the weed grows 100 seeds and will
grow them shortly after mowed.
Likes moist areas. Needs to be
constantly irrigated to survive
One of the most invasive weeds
Clean ALL equipment after
using it in infested areas to
stop spreading
To get rid of them you can hoe
them out or hand pull them.
Do this frequently to prevent
Broadleaf Plantain
 broadleaf perennial that tolerates many conditions
 Tap root and whole plant
such as; dry, wet, & heavy soil.
 Crowds native species of plants and can cause
clumps that are bad for traction on athletic fields
 This plant spreads by seed
 This plant can be invasive if not taken care of fast
 Use a long handle tool and dig out the
plants tap root, it is most effective this way.
 Preen Weed Control is a weed killer and
preventer that works great on wide spread
out breaks.
Buckhorn Plantain
Buckhorn is similar to the Broadleaf Plantain but have
longer and skinnier leaves
Buckhorn leaves are 1 1/2 “ wide and up to 8” long.
Buckhorns are in the plantain family just as
They reproduce by seeds and roots
Like the Broadleaf, it likes moist places and
is a cool season peranial
Can be invasive if not taken care of
To kill or prevent this weed;
Apply postemergence herbicides in mid
spring early summer or mid to late
To remove this with out chemicals pull
as much as the tap root out as possible.
Treatment with chemicals can be done
by your self or with a pro.
Self; use herbicides
Pro; they use stronger chems and only
they can purchase them
 Reproduces by seeds and roots
 This weed is invasive so deal with it as
soon as possible
 Winter annual
Spreads fast and grows in every state
Prefers shady, cool, and moist environment's
 Growing is done end of winter
early spring and is the best time to
dig it out. REMOVE ENTIRE PLANT!!!
 removal and prevention can be
done chemically; herbicides,
glyphosate or triclopyr are very
 Can grow in dry and
wet land
Summer annual
Spread by seed
Crab grass is invasive
To kill this weed use
preemergence or postemergence
 Use chemicals in late April or
early May
 Can grow in
any situation
 Dandelion life cycle
 Flowered Dandelion
As you can see from the life cycle
picture this plants changes and
spreads by seeds that are loose and
blow away.
Are an Annual
To kill with out chemicals dig out
the Dandelion before it gets
Killing with chemicals use; 2,4-D,
You'll probably find it mixed with
other broad- leaved weed-killers
such as MCPP (Mecoprop) and
 Grows in unmanaged
 Last week of February and start
flowering the first of March.
 Winter annual weed that you can count
on showing up every year
 It can be a pest in wheat fields as well as
lawns and wasteland.
 Spread by seed
 Is invasive
Henbit is most effectively controlled with
herbicides in the fall while plants are
small and immature. Products containing
dicamba, MCPP and 2,4-D have
demonstrated effective control in the fall
and early spring. In dormant
bermudagrass, glyphosate, diquat or
metribuzin will control henbit.
 Tubers 
Nutsedges grow mainly from tubers formed on
underground, horizontal creeping stems called
Spreads by Tubers and rhizomes
To kill without chemicals; pull out the
Tubers and Rhizomes.
Kill with chemicals; dichlobenil (Casoron),
metolachlor (Pennant), and
dimethenamid-P (a component of
Freehand). Metolachlor and
Spreads fast by seed
Identified as a clover
To kill with out chemicals; pull out the
large tap root while plant is still small
To kill with chemicals; preemergence
herbicide, then spot treat glyphosate.
 Summer annual
 Spreads by seeds and sometimes stem
 Biological Control; Purslane sawfly. Eats
and reproduces on weed.
 Chemical Control; Chemical control is
generally not necessary
 Preemergent control; The herbicides
dithiopyr, pendimethalin, or
combinations of benefin and trifluralin
or benefin and oryzalin
 Not invasive
 To kill, hand pull is the best
White clover
