It can grow an inch or two a day, produce nearly a million seeds and emerge at almost any point in the growing season.

Researchers have sequenced the genomes of Palmer amaranth and other pigweed species, uncovering key mechanisms behind ...

New chromosome-level genomes have been published for three troublesome Amaranthus weed species: Palmer amaranth and redroot and smooth pigweed. The advancement represents a major leap in scientists’ ...

More specifically, planting soybean over a cereal rye cover crop demonstrates an effective practice to both produce soybean and to suppress two problematic Amaranthus weed species: waterhemp and ...

Knowing how devastating Palmer amaranth can be, it’s important that farmers learn how to identify and manage the weed. Scouting fields to determine which weeds are most prevalent is a key step ...

Ask corn growers what their No. 1 weed problem is today, and it’s likely at least one of these three – Palmer amaranth (pigweed), waterhemp or common ragweed – will be listed in their response.

My research is focused on improving productivity and resilience of forage crop production systems. Research interests include: agronomic management factors that influence crop weed competition, the ...

Several of those — kochia, Palmer amaranth and, in particular last year, waterhemp — have been flagged as serious weed ...
