What weeds should you be worried about in your fields? An early August Farm Journal Pulse provides some insight. More than 1,500 farmers shared their weed challenges, answering the question: What is your most significant weed problem?

Waterhemp tops the list, closely followed by marestail/horseweed and then ragweed.

Aaron Hager, University of Illinois Extension weed scientist, says certain weed species tend to thrive better in certain environments, whereas other species seem to adapt to a very broad range of landscapes.

Additionally, weed species can quickly expand their footprint. "The introduction of a new weed species into an area where it had not previously occurred can happen as easily as someone inadvertently depositing seed that had attached to their clothing when they visited a field where the species was present," he says. "Long-distance seed movement is of great concern and is an excellent mechanism by which species move from region to region."
