As a competitive weed, lambsquarters cuts yield: One uncontrolled weed per square yard can cut soybean yields up to 7 bushels per acre, according to WeedSOFT® computer models. Across the Corn Belt, growers and retailers are finding that it takes higher rates of glyphosate to effectively control lambsquarters in GT crops.
“We need nearly double the rates of glyphosate to prevent lambsquarters escapes in soybeans, which costs an additional $7 to $8 per acre.”
Mark Hoppe, agronomist, Cooperative Plus Inc.,
East Troy, Wis.
“When lambsquarters haven’t been controlled well with a pre-emergence herbicide, it has cost about $6 to $8 in herbicides and about $6 in application costs to clean it up.”
Doug Wical, agronomy manager, Southwest Landmark,
South Charleston, Ohio
