Conservation tillage systems (no-till) and the reduced use of residual herbicides, most likely have contributed to increased presence of winter annual weeds in Michigan soybean fields. Soil-borne insects and SCN have presented challenges in reduced tillage systems in recent years. The growth habit of winter annuals may act as a "green bridge" for the survival of next year's insects and diseases. Fifty-five no-till fields were sampled during the 2007 and 2008 crop years; common chickweed, purple deadnettle and Shepherd's purse were the most common winter annuals identified. Three fields had wireworms present and ten had grubs present. Asiatic garden beetle (2), European chafer (3),...
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.
