This is a continuing project that is screening for herbicide resistance of selected weeds in no-till soybean production systems. Past results indicate: ~ Herbicide resistance has not been detected in the horseweed samples submitted in 2007 for evaluation. ~In 2007, three common ragweed, three common lambsquarter and two giant ragweed were screened for herbicide resistance with the following results: All three common ragweed samples were ALS-resistant; Two common lambsquarter were triazine resistant while the other was ALS-resistant; and no glyphosate resistance was detected.
The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
