BLOOMINGTON, IL – Even though university researchers have identified a probable glyphosate-resistant Palmer pigweed case at specific sites in Georgia-one that they are calling a “difficult to control” case until it is confirmed through genetic testing-Illinois soybean farmers can rest assured that their checkoff investment is investigating weed control and resistance, and so far, no weeds in the state have been found to be glyphosate resistant.

“As with this case in Georgia, once again, weeds have shown their ability to adapt their sensitivity to Roundup Ready systems,” said Bryan Young, weed science associate professor, Southern Illinois University (SIU). “What we are seeing is that weed control with glyphosate is not as effective as it once was.”

It is widely agreed among soybean farmers and researchers that glyphosate is the single most effective herbicide for use in soybean fields. Some of the most challenging decisions in glyphosate-resistant soybean management entail the number of glyphosate applications necessary for season-long weed control and what rate or formulation of glyphosate is best.
