Abstract
The roots of ragweed Ambrosia trifida exude chemical compounds that have insecticidal activities. This paper reports a survey conducted in a soybean field infested with ragweed to determine if the ragweed affected the populations of plant parasitic nematodes. There was a strong indication that the ragweed decreased populations of plant parasitic nematodes in some cases.
