Giant ragweed trial

The most problematic weed at the NIARC (and much of northern Illinois) is Giant ragweed. Area farmer and NIARC advisory board member Ken Beck visited the center today and posed in front of a check (no herbicide) area at one of our trials. Look very closely to find the soybean under the towering ragweed! in addition to our traditional herbicide trials that deal with our population of Giant rag, we have a targeted study that is looking at tank-mix and application timings for Giant ragweed control in soybean. Yield and control data will be shared post harvest.
