HomeMy WebLinkAboutThe Citizen, 1998-01-07, Page 9Weed resistance is a growing problem but
it is not unique or much different than
resistance to antibiotics, insecticides, and
fungicides. In Ontario last year there were
several confirmed cases of pigweed
resistance to a herbicide product called
Pursuit.
There are now approximately 190 weeds
that are resistant to some form of herbicide.
Most of these weed species are in the
triazines and in group two family of
herbicides including products such as
Pursuit, Ultim and Accent. The herbicides
that we use in Ontario are divided into
groups based on how they work on a weed
(mode of action). They are divided into
approximately 20 different groups. For
example, Banvel and 2, 4-D are in the same
group called the Synthetic Auxins. Pursuit,
Ultim, and Accent are also in a group
together called ALS Inhibitors.
It is clear that a potential problem is
developing because many of the corn and
soybean acres use herbicides from the group
to which Pursuit, Ultim and Accent belong.
Last year we saw the tip of the iceberg with
several confirmed cases of pigweed
resistance to Pursuit.
There are several factors that lead to
herbicide resistance. One factor is the
existence of a genetically different pigweed
plant; this plant looks like all the other
pigweeds but it is not killed by the
herbicide. A second factor is repeated
application of the same herbicide; in this
situation the weed produces offspring that
are also resistant creating a problem in just
a few short years. Another factor is long
residual activity when it is applied alone or
not in combination with other herbicides.
Weeds that usually develop resistance are
originally very susceptible to that herbicide.
They are frequently weeds that produce
much seed and are usually annuals meaning
that they complete their life cycle in one
growing season.
To manage this potential problem that
everyone who uses herbicides has, growers
should be diligent in mixing different
groups of herbicides when choosing or
planning a weed control program. Also,
rotation of the various groups as well as
crop rotation is important in management
from year to year. Another method might be
to consider mechanical weed control with a
cultivator. The main objective in the end is
to try to confuse the weed. If you are using
Pursuit in your soybeans and Ultim or
Accent in your corn you are not really
changing your herbicides.
If you believe that this problem can not
happen to you, you are setting yourself up
for potential disaster. There have been
many confirmed resistant weeds to the
common herbicides that we use today.
Many growers have already experienced
Altrazine resistant lambsquarters and
pigweed.
Weed resistance is a manageable
problem. There are products on the market
today that I believe most growers would not
want to lose as a tool to manage weeds.
Using new tools such as Roundup Ready
and crops and Liberty Link crops will also
prolong the life of all the weed control
options available. Using all the tools
available for weed control rather than one or
two will prolong the life of this very
effective technology. Make a plan on a field
by field basis to rotate your herbicide
groups for next year. Call for help if you
need assistance.
