In a Purdue Extension report, “2,4-D-
and Dicamba-tolerant Crops -- Some
Facts to Consider,” one of the con-
cluding statements said: “Often, there
are no effective herbicides that are
easily available for some crops, or it is
not desirable or possible to use more
intensive tillage on large acreages.
The presence of glyphosate-resistant
weeds imperils the long-term sustain-
ability of the RR (Roundup Ready)
system unless producers practice more
integrated weed management that
relies less on the sole use of glypho-
sate.”
In 1998, the USDA National Agricul-
tural Statistics Service began publish-
ing farmer surveys of pest manage-
ment practices. Farmers were asked
to answer “yes/no” questions, which
were then categorized for the report
into one of four pest management
categories: prevention, avoidance,
monitoring and suppression.
Two tables were created for each crop:
corn and soybeans. The first table
shows percent of planted acres; the
second table shows percent of farms.
Beginning in 2000, the survey reflects
the introduction of genetically modi-
fied soybeans, and soon to follow,
corn traits with insect and herbicide
resistance.

ccording to University of Illinois Extension
director John Fulton, “One of the major prob-
lems this year was the control of mare’s-tail
and waterhemp (mainly in soybeans). Both these
weeds have been classified as having resistance to
glyphosate (Roundup).”
