Abstract

Suspected triazine resistant Pennsylvania smartweed plants were discovered near Holy Cross, Dubuque County, IA. Subsequent variable chlorophyll a fluorescence assays confirmed these selections to be triazine resistant. This is the first reported evidence of s-triazine resistance in Pennsylvania smartweed.
