When glyphosate no longer provides complete weed control in a grower's field the tendency is for the grower to tank-mix glyphosate with other herbicides in subsequent post emergence applications. However, preliminary research has shown that growers should invest most of their weed management costs (herbicides) in tactics that focus on using effective herbicides early in the growing season. Investing the same amount of money on mid- to late-season weed management (herbicide use) may prove to be less effective for controlling weeds and reduce soybean yield. The objective of the research is to discern the success of herbicide programs within three different cost ranges that may be used by...
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.
