The majority of Michigan soybean acreage is planted in no-till. This along with other soil conservation practices has increased the incidence of winter annual weeds. Winter annual's growth habit may act as a "green bridge" from one year to the next for insects and diseases or serve as an alternate host for other crops pests. Indiana researchers reported SCN reproduces on purple deadnettle. The interaction of winter annuals and increasing insect pressure in soybean will be examined in this checkoff-funded project along with timely management of winter annual weeds.
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.
