Rainy day entertainment – get up to speed on pigweed ID

Palmer amaranth in soybeans

When you finish every possible indoor task during this rainy spell, take a few minutes and check out our latest video on pigweed identification.  The video compares four aspects of pigweed biology that we use to differentiate between redroot pigweed, waterhemp, and Palmer amaranth – pubescence, petiole length, leaf shape, and inflorescence (seedhead) characteristics.  Find it at the OSU weed management website – http://u.osu.edu/osuweeds.  There are far worse ways to spend a few minutes.
