Because it propagates

Refrigerated Trailers
underground rhizomes,
quackgrass is difficult
to control and almost
impossible to eradicate.
The weed’s dual
reproductive capabilit
ies have earned it the
title “tiger of the corn
field”.
Infestations, while
particularly heavy m
Pennsylvania, Min
nesota, Wisconsin,
Michigan, New York,
and Ohio, are found
everywhere except
several states m the
deep south and
southeast.
Quackgrass leaves
are about one-quarter
uich wide and somewhat
hairy on the upper
surface, with a pair of
claw-like “hooks”
clasping the stem.
Rhizomes are white
when young, later
turning straw-colored,
and have very sharp
points which can easily
spread through soil.
More Thin Tillage
The rhizomes serve as
reserve food storage,
enabling the weed to
establish new growth
even when entirely
separated from the
parent plant. Massive
development of
rhizomes and roots - up
to six tons per acre -
makes the plant difficult
to control by cultivation
alone, although
repeated tillage will
significantly reduce
stand and vigor.
In addition, rhizomes
reportedly secrete a
toxic substance which'
enhances the com
petitive ability of the
plant and inhibits the
germination of seeds.
In fact, quackgrass is
so competitive that
university field plots
with quackgrass in
festations yielded only
15 bushels per acre,
whereas fields where
quackgrass was
eliminated reached 80
bushels per acre.
Effective quackgrass
control is the result of
an integrated approach,
utilizing a combination
of chemical and non
chemical means.
Tillage alone has not
been an efficient
method because the
land must be taken out
of production for ex
tended periods of tune
to allow for frequent and
expensive tillage
operations.
The traditional - but
not always most
practical - method of
quackgrass control is to
grow com on infested
acreage for three years
using high rates of
atrazme.
Farmers growing
continuous com have
achieved satisfactory
results using split ap
plications of atrazme:
one applied prior to fall
or spring plowing, and
the other as a pre
emergence treatment in
the spring. Higher rates
are used the first year,
followed by reduced
rates m the second and
third years
