Glyphosate resistant tall waterhemp and glyphosate resistant giant ragweed infestations are  intense.  Waterhemp and Giant Ragweed populations show evidence of PPO resistance, but at a lesser frequency than glyphosate resistance.  Quinoa (comparable to common lambsquarters), volunteer corn, and other grass species can be artificially established without issue. Marestail, cocklebur, giant foxtail, and velvet leaf have been observed at a less consistent frequency.
