I was texted the following picture (slightly blurry) early yesterday morning from a SW-GA crop consultant. He commented that it was all over the field.
This is Florida beggarweed (kidney-shaped cotyledons). When I first got to GA in 1999, Florida beggarweed was the #1 peanut weed. It became less troublesome when Valor (flumioxazin) was registered in 2001 (very effective) and when Palmer amaranth exploded. Florida beggarweed tends to be a later emerging weed and prospers during wetter conditions.
At this point in the growing season, there are not many good options for controlling Florida beggarweed in peanut. The first option is a POST (60 days after peanut emergence) application of Classic (chlorimuron). The other option is to use Gramoxone (paraquat) in a non-selective applicator (wiper, sponge, rope-wick). Both of these options are described on page 224 of the 2025 UGA Pest Control Handbook and/or listed below. Please carefully read the comment sections of these recommendations. Peanut cultivar tolerance to Classic is a major concern. If a newer peanut cultivar is not listed in the comment section (i.e. Arnie, TifNV-HG, etc.), that means I DO NOT have any tolerance data and have no clue what will happen.
